Abstract

The invention discloses a microbial sewage treating agent used for livestock and poultry breeding wastewater treatment. In the microbial sewage treating agent, proper bacterial strains are selected according to the characteristics of livestock and poultry breeding wastewater for being optimizingly combined, wherein effective substances and secretion substances, generated during growth processes, of the microorganisms are formed into substrates and raw materials which are mutually grown, and a microbial community, which is complex in composition, is stable in structure, is wide in functions, including various bacteria is formed through a mutual symbiotic and proliferative relationship. The microorganisms are beneficial to each other during a purification process of the livestock and poultry breeding wastewater and a best cooperative advantage of the microorganisms is achieved. The microbial sewage treating agent has a high-efficient treatment effect, achieves qualified discharge of the wastewater, is low in cost and is significant in economic benefit.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a microbial sewage treatment agent used for the treatment of livestock and poultry breeding wastewater. Background technique [0002] The amount of wastewater discharged by large-scale farms every day is large and concentrated, and the wastewater contains a large number of pollutants, such as heavy metals, residual veterinary drugs and a large number of pathogens. If it is discharged into the environment or directly for agricultural use without treatment, it will cause local ecological problems. Serious pollution of the environment and farmland. [0003] Livestock and poultry breeding wastewater is a high-concentration organic wastewater rich in a large number of pathogens, and contains a lot of nitrogen, phosphorus and potassium components. The effect of ordinary chemical treatment and physical technology treatment is not good, the treatment is difficult, and it is difficult to meet t...
