Water treatment

●Waste liquid treatment：

After the liquid is fermented, it can meet the requirements of fully decomposed, harmless and hygienic in the "Technical Specifications for Returning Livestock and Poultry Manure" GB/T25246-2010, and it can meet the needs of crops for nutrients when applied to farmland to maintain or Improve soil fertility and soil activity. The system is simple, quick to construct, no leakage and no evaporation during storage, and can reduce the nitrogen loss of manure during manure storage. It not only reduces the cost of manure storage in cattle farms, but also efficiently retains the fertilizer effect of manure. At the same time, it does not cause pollution to the surrounding atmosphere, soil, groundwater, etc. during the storage process. It is a green, environmentally friendly, efficient and economical manure storage method. .

● Sewage treatment：

The company's sewage treatment mainly uses nitrite-based simultaneous denitrification (SNR-N) as the core technology process, and uses this technology to deploy various types of high-concentration organic wastewater such as breeding wastewater, slaughtering and food processing wastewater. It has the characteristics of low investment, less land occupation, low operating cost and simple operation. After being treated by this process, the waste liquid can be discharged or reused up to the standard, and the environmental protection pressure of the pasture can be effectively solved.

1. Strengthen pretreatment to reduce back-end treatment load and reduce activated sludge production;

2. The film-covered biogas digester is used as an anaerobic treatment facility, with large capacity, low investment cost and low operating cost;

3. Adopt short-range denitrification integrated process, save energy and reduce consumption, occupy a small area, have less residual sludge, and have high pollutant removal efficiency and operation and maintenance automation;

4. The key process links and key equipment adopt online maintenance and backup to ensure the continuous and stable operation of the system for 24 hours;

5. The design takes into account the impact resistance of different water quality and quantity in different seasons;

6. Comprehensive comparison, the design considers investment cost, operating cost, safety and stability, operation and maintenance and other comprehensive cost performance;

7. Automatic control: The key links can realize online monitoring and automatic control to ensure linkage and intelligent control.
