Problems solved by technology

The sewage of livestock and poultry breeding industry contains more nitrogen, phosphorus, potassium and other nutrients. If it is directly, continuously and excessively applied without any treatment, it will have adverse effects on the growth of soil and crops, such as reducing crop yields. , Delaying the maturity period, affecting the production of subsequent crops, etc. In view of the many problems caused by the above-mentioned farm sewage, it is urgent to develop a new process and new method to meet the needs of farm sewage treatment, and at the same time alleviate the environmental hazards of farm sewage pressure

Abstract

The invention discloses a deep treatment method for sewage of breeding plants. The deep treatment method is mainly characterized by comprising the steps of stirring a flocculating agent of a special formula with sewage to react, treating by virtue of a multi-media filter, carrying out metabolism treatment by virtue of a compound microbial agent in an aeration tank, carrying out high voltage pulse electrocoagulation, carrying out elution and filtration by virtue of ion exchange resin, stirring the treated sewage with a special compound sewage treating agent, standing, filtering, and finally carrying out reverse osmosis concentration by virtue of a high-pressure pump, so as to obtain treated water meeting the emission standard. The deep treatment method has the beneficial effects that the sewage treatment efficiency is high, and the discharged treated water obtained by virtue of the sewage treatment method of an optimized process can meet the national standard; and meanwhile, the process is simple and feasible and strong in operability, has no environmental pollution, can meet the industrial requirements and has relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for advanced treatment of sewage from breeding plants. Background technique [0002] The livestock and poultry industry is an important part of my country's agriculture and rural economy. The environmental pollution caused by the vigorous development of the livestock and poultry industry is becoming more and more serious. The emissions of major pollutants from domestic, domestic and industrial sources were analyzed and summarized. Among the agricultural sources, the COD and ammonia nitrogen emissions from the livestock and poultry breeding industry were 12.6826 million tons and 717,300 tons respectively, accounting for 95.8% and 78.1% of the agricultural source COD and ammonia nitrogen emissions, accounting for 41.9% of the national COD and ammonia nitrogen emissions and 41.5%. At present, the large-scale livestock and poultry breeding sewage discharged by larg...
