This is a sludge cow dung organic fertilizer production line in Argentina project. What is very special is that this project uses sludge and cow dung as the main raw materials.
With the acceleration of urbanization, the collection and treatment rate of urban sewage in Argentina has increased year by year, and the amount of comprehensive sludge generated in cities and towns and life has also increased sharply.
At present, the main methods for sludge disposal are landfill and incineration, which not only produce secondary pollution, but also occupy a lot of land and consume a lot of energy. Sludge treatment has become a major problem faced by the environmental protection department in Argentina.
Sludge is a solid produced after sewage treatment, containing a large amount of organic matter. Processing sludge into organic fertilizer has simple process, convenient management, low energy consumption and low operating cost, which can meet the requirements of comprehensive sludge resource utilization in cities and towns and life.
In order to meet market demand, the client of this project, an Argentine trading company, invested 140,000 US dollars to build an "organic fertilizer production project". After the project is completed, it will produce 50,000 tons of organic fertilizer annually.
The sludge cow dung organic fertilizer production line in Argentina project processes powdered organic fertilizer. The project has a labor quota of 20 people, with two shifts, 8 hours per shift, and 330 working days per year.

The main raw and auxiliary materials and energy consumption of this sludge cow dung organic fertilizer production line in Argentina project are shown in the table below.
| Item | No. | Name | Amount | Remarks |
| Raw and auxiliary materials | 1 | Sewage sludge | 30,000 t/a | Urban sewage treatment plant |
| 2 | Cow dung | 20,000 t/a | Local breeding area, fermented | |
| 3 | Micro life deodorant | 2.0t/a | Production machine storage deodorant | |
| 4 | EM bacterial agent | 3.0t/a | Purchased from outside, stored in the raw material area of the factory | |
| Energy consumption | 1 | Fresh water | 132m3/a | Supplied by the local water supply network |
| 2 | Electricity | 100,000 kWh/a | Supplied by the local power supply network |
The physical and chemical properties of the main raw and auxiliary materials are as follows:
Sludge:
The sludge produced by the sludge cow dung organic fertilizer production line in Argentina project comes from the local sewage treatment plant. The sludge is mainly composed of low-level organic matter such as amino acids, humic acid, bacteria and their metabolites, polycyclic aromatic hydrocarbons, heterocyclic compounds, organic sulfides, volatile odors, organic fluorides, etc. In addition, it also contains inorganic sand and heavy metal substances such as mercury, cadmium, and lead.
The sludge accepted by the project is all sludge produced by domestic sewage treatment plants. The sludge of this project does not use sludge from industrial sewage plants. At the same time, a sludge monitoring report must be provided each time it is transported into the plant area. The plant area can only accept sludge after it is qualified. Otherwise, unqualified sludge will have a huge harm to earthworms. It should meet the standard requirements and meet the pollutant control standards for sludge agricultural use.
Microbial deodorant:
Microbial deodorant follows the principle of microecological engineering. On the basis of fully learning from foreign advanced composite microbial technology, it adopts microecological engineering technology and uses modern biotechnology to produce a new type of biological deodorant composed of beneficial microorganisms of different properties.
Microbial deodorants can effectively remove malodorous gases such as hydrogen sulfide and ammonia, have no toxic side effects on humans, animals and plants, and do not cause any pollution to the environment. Microbial deodorants contain a variety of strains with strong decomposition capabilities.
There is a symbiotic relationship between the strains to form a functional group. Beneficial microorganisms effectively inhibit the corruption and decomposition of spoilage bacteria and turn to fermentation and decomposition. The organic acids produced can degrade (decompose), absorb and fix N and S oxides.
EM bacterial agent:
It is composed of a large number of friendly strains such as Bacillus, mold, yeast, and actinomycetes. It is a medium and high temperature aerobic bacterial agent that is good at decomposing crude protein, fat, cellulose, and lignocellulose.
It can quickly heat up the fermented product, efficiently kill harmful pathogens, insect eggs and weed seeds, etc., quickly disperse macromolecular nutrients such as nitrogen, phosphorus, and potassium in the fermented product, and convert them into small molecular fast-acting nutrients that are beneficial to crop absorption, and form a large amount of humus and trace elements.
It is a pure microbial live spore preparation, and the product contains microbial strains with nitrogen fixation, phosphorus solubilization, and potassium solubilization functions. Nitrogen-fixing bacteria can produce a large amount of nitrogenase, which converts nitrogen molecules into nitrogen atoms that can be absorbed by plants for crops to use. At the same time, it has the ability to remove odor and improve the environment.
The removal rate of hydrogen sulfide and ammonia is not less than 60%. The fermented fertilizer has the effects of reducing soil bulk density, increasing soil activity, strengthening roots, curbing soil-borne diseases, and increasing crop yield and quality.
This sludge cow dung organic fertilizer production line in Argentina project uses urban domestic sludge and cow dung as raw materials and is mixed in proportion.
Fresh sludge mainly comes from local sewage treatment plants. In order to avoid the impact of odor generated by raw material transportation on sensitive points along the transportation route, the environmental impact assessment requires that the sludge transportation route must be reasonably selected, and try to choose a transportation route with good road conditions and avoiding most sensitive targets. Avoid transportation during peak traffic hours.
During the sludge transportation process, strengthen management, close the transportation vehicles, and prohibit omission and throwing along the way to avoid secondary pollution during transportation.
The specific process flow is as follows:
Mix the purchased sludge with cow dung, add EM bacteria agent and stir, and use biological deodorant for spraying to achieve the deodorizing effect.
The project sludge is transported from the sewage treatment plant to the project mixing area for unloading and mixing. The sludge stays in the mixing area for no more than 2 hours. The sludge is not stored on site for a long time.
It is mixed in time according to the principle of mixing immediately after transportation and then transported out of the factory by belt conveyor and car.

The water used in this sludge cow dung organic fertilizer production line in Argentina project is provided by the local water supply network, mainly for domestic use, and the project does not use water for production. Domestic water: The project has a labor quota of 20 people, working 330 days a year. All employees are nearby villagers.
The project does not have a canteen or dormitory. According to the calculation of 40L/person·d, the project has a labor quota of 20 people and a water consumption of 264m3/a.
The domestic sewage generated by this project is calculated as 80% of the water consumption, so the amount of washing wastewater generated is 0.32m3/d (105.6m3/a).
All washing wastewater is splashed to suppress dust and is not discharged; fecal sewage is discharged into the anti-seepage dry toilet in the factory area, which is regularly cleaned and used as agricultural fertilizer.
The power supply for this sludge cow dung organic fertilizer production line in Argentina project is provided by the local power supply network, with an annual power consumption of 100,000 kWh, which can meet the power requirements of the project.
In addition to this organic fertilizer production project, we have built many alfalfa pellet production lines, cattle feed production lines, poultry feed production lines, wood pellet production lines, straw pellet production lines, biomass pellet production lines and organic fertilizer production line projects in Argentina.
