List of main biofertilizer manufacturing equipment list

The main equipment used in this biofertilizer manufacturing plant in Algeria project are as follows:

Algeria biofertilizer manufacturing Process design

1. The raw materials (livestock and poultry manure) are transported from the poultry farm to the fresh chicken manure storage area in the factory. After entering the factory, the microbial agent and sawdust are added and fully stirred and stored for about 3-5 days (the main function is to increase the temperature).
2. The main pollutants during the stirring and storage process are dust and odor; after meeting the temperature requirements, the forklift is transported to the fermentation tank and fermented in the fermentation tank for about 15 days. During the fermentation process, it is turned over irregularly according to the fermentation situation.
3. After the fermentation is completed, it is transported to the yard for aging and incubation to further increase the microbial content. After the incubation is completed, part of the material is in block form and needs to be crushed and screened.
4. The screening that meets the pellet size requirements (6mm) enters the packaging area for bagging and temporary storage, and the particle size greater than 6mm is returned to the fermentation tank for re-fermentation.
5. Since the moisture content of the product is relatively high (about 30%) and the crushing process is mainly for crushing large block products, the amount of dust generated during the crushing and screening process is relatively small, and the main pollutant in the crushing and screening process is noise; the project workshop is a negative pressure workshop, which is fully enclosed and equipped with a negative pressure fan with an air volume of 11000m3/h. The air is continuously exhausted to keep the workshop in a negative pressure state.

Plane Layout

The rationality of the overall plan layout of the plant area: The biofertilizer manufacturing plant in Algeria project is based on the premise of meeting the production process, considering the requirements of transportation, safety, and hygiene, and combining the natural terrain conditions of the project site.

It is divided and combined according to the different functions of various facilities, and strives to make the plan layout compact and reasonable, save land, be beneficial to production, and facilitate management.

The specific layout is as follows:

The factory has a total of one production plant, one product warehouse and one office area. The production plant is located on the north side of the factory, and the product warehouse and office area are located on the south side of the factory. The stench generated in the production area has little impact on the office area.

An initial rainwater collection pool (20m3) is set at the lowest point of the factory entrance and exit. The initial rainwater in the factory can flow into the collection pool by gravity to ensure that the initial rainwater is not discharged.

The biofertilizer manufacturing plant in Algeria is a closed steel frame structure plant. The plant is oriented north-south. The entrance and exit of the plant are located on the south side of the plant. The production lines inside the plant are arranged from north to south. From north to south, the raw and auxiliary material storage area, fermentation tank, aging and composting area, packaging area, etc. are arranged respectively.

The west side of the plant is the forklift passage inside the plant. The packaging area is located on the south side of the plant, close to the entrance and exit, which is convenient for transportation.

From the perspective of environmental protection, the project's production plant is located downwind of the local dominant wind direction and the main odor and noise pollution areas are a certain distance away from the office area.

The noise and exhaust gas generated during the production process have a reduced impact on employees in the plant area. Therefore, the design and layout of the plant area is reasonable, the logistics are smooth, and the sanitary conditions, transportation, safety, and fire protection all meet the needs of the enterprise and environmental protection requirements.

Public works

The livestock manure of the biofertilizer manufacturing plant in Algeria project is directly sent to the breeding farm and transported to the fresh chicken manure storage area in the plant. The vehicles are not washed in the plant, and there is no vehicle washing waste; the plant is mainly cleaned by sweeping; the production equipment is purged instead of flushing.

Therefore, the water used during the organic fertilizer production project operation period is mainly domestic water and spray tower circulation water. The water is provided by the local tap water network. The plant area is equipped with a water supply system. The water supply capacity is designed according to the needs of production and life to meet the water needs of various systems in the plant area.

Domestic water

The biofertilizer manufacturing plant in Algeria project has a staff of 8 people, all of whom are nearby villagers and do not eat and stay in the plant area. The living water consumption of personnel is calculated as 40L/person·d, then the living water consumption is 0.32m3/d (80m3/a), and the drainage coefficient is calculated as 0.85, then the living sewage generated by project employees is 0.27m3/d (64.8m3/a).

Production water

Spray tower circulating water

The circulating water volume of the spray process is about 1m3/d, and the water loss is calculated as 10% of the circulating water volume. Therefore, 0.1m3/d of fresh water needs to be added every day. The spray water is replaced regularly, and the replaced wastewater is manually sprayed to the fermentation pile and not discharged.

Leachate

After the raw materials of the bio organic fertilizer production line project enter the site, they are directly transported to the fresh chicken manure storage area, and sawdust, bacterial agents, etc. are immediately added for mixing. No leachate is generated. The biofertilizer manufacturing plant in Algeria project uses natural fermentation technology. No wastewater is generated during the normal fermentation process. The water evaporates completely with the fermentation process.

A small amount of waste liquid is generated in the early stage of natural fermentation. The waste liquid is absorbed by the compost raw materials. No waste liquid is precipitated in the later stage of composting. Therefore, this project does not generate compost leachate.

Initial rainwater

A small amount of dust is generated in the links of raw material transportation, loading and unloading, transportation and product production engineering in the site. In the rainy season, surface rainwater runoff washes the ground of the production area and auxiliary production area, so that the initial rainwater will contain a large amount of SS and other pollutants, but as the rainfall continues, the SS concentration will gradually decrease.

Intercepting drainage ditches are built around the site to lead the initial rainwater in the site to the initial rainwater sedimentation tank (20m3) through the intercepting drainage ditch for treatment and reuse for road sprinkling and greening water in the factory area. According to the calculation of 10 times per year, the annual initial rainwater generation of the project is 187m3/a, and the main pollutant is SS, with a concentration of about SS:500mg/L. Since fire-fighting water is not a periodic water use, it is not included in the water balance.

The drainage system of the project plant adopts a rainwater and sewage diversion drainage system. There are interception drainage ditches around the project site, and the inner wall of the interception ditch is smoothed with cement mortar. The initial rainwater is treated in the initial rainwater sedimentation tank and reused for watering and dust suppression in the plant area and roads and greening the plant area.

The domestic sewage of the project is pre-treated in the septic tank, and then manually cleaned and sent to the fermentation workshop for spraying, and is not discharged; the regularly replaced spray wastewater is manually transported to the fermentation workshop and sprayed on the fermentation pile, and is not discharged.

Analysis of the conformity of the project with the technical specifications for livestock and poultry manure composting

Environmental protection engineering

The environmental protection measures adopted by this biofertilizer manufacturing plant in Algeria project are as follows:

Sewage treatment:

The factory area is divided into rainwater and sewage, and the initial rainwater is collected in a sedimentation tank of 20m3. The initial rainwater is reused after sedimentation in the initial rainwater sedimentation tank, and is not discharged.

The domestic sewage of the project is collected and pre-treated in a septic tank (1m3), and then manually cleaned and sprayed to the fermentation workshop, and is not discharged. The regularly replaced spray wastewater is manually transported to the fermentation workshop and sprayed to the fermentation pile, and is not discharged.

Solid waste treatment:

The biofertilizer manufacturing plant in Algeria project domestic garbage is collected and entrusted to the sanitation department for transportation; the sedimentation sludge of the spray tower is regularly cleaned and returned to the fermentation workshop as raw material.

The screened material is directly returned to the fermentation process as raw material, and the recyclable part of the waste packaging should be recycled by the waste recycling unit, and the rest is collected and entrusted to the local sanitation department for regular transportation and disposal; the waste oil is collected and temporarily stored in the hazardous waste temporary storage room (2m2), and regularly handed over to qualified units for recycling and disposal.

Noise control:

Foundation shock absorption and time control meet the "Environmental Noise Emission Standards for Industrial Enterprises".

Waste gas treatment:

The factory area is regularly sprayed with deodorant and the conveyor belt is closed; the production workshop is a closed negative pressure workshop, and a negative pressure fan (air volume 11000m3/h) is installed to collect the workshop waste gas.

The collected waste gas is treated by a water spray dust collector (particle removal efficiency 80%) and then discharged through a 15m high exhaust pipe (DA001).

What is the prospect of building biofertilizer manufacturing plant in Algeria?

‌The prospects for processing organic fertilizer in Algeria are very broad‌. The following are several key factors to support this conclusion:

• ‌Market demand‌:
  With the increase in environmental awareness, farmers are increasingly inclined to use organic fertilizers to improve crop quality. Algeria's agricultural development level is low, lacking excellent varieties and scientific planting techniques, which provides a broad market space for the application of organic fertilizer‌. In addition, the government's support policy for sustainable agricultural development also helps to promote the market demand for organic fertilizer‌.
• ‌Policy support‌:
  The Algerian government encourages agricultural development and provides support policies such as tax incentives and financial subsidies, which helps to reduce the cost of entrepreneurship and improve the profitability of organic fertilizer processing plants‌.
• ‌Cost-benefit analysis‌:
  Although the initial investment and operating costs of organic fertilizer processing plants are high, the cost can be greatly reduced by cooperating with farmers to purchase raw materials. In addition, the price of organic fertilizers is generally higher than that of chemical fertilizers, and the profit margin is larger.
• ‌Sustainable development‌:
  The organic fertilizer processing industry is in line with the development trend of green agriculture and helps to protect the environment. As people pay more and more attention to health and environmental protection, the organic fertilizer market will continue to maintain a strong growth trend, with an annual growth rate of 15% to 20%.
