Abstract

The invention belongs to the technical field of environment friendliness, and discloses a biological preparation for treating domestic sewage. The biological preparation is formed by mixing a mixed bacterium liquid and an auxiliary preparation material at the weight ratio of 1:1. The invention further discloses a method for treating the domestic sewage via the biological preparation. In the biological preparation, various microorganisms are matched to perform actions of symbiotic coordination and cannot generate mutual antagonism; various pollutants in the sewage can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a biological preparation for treating domestic sewage. Background technique [0002] Domestic sewage is the sewage produced in the process of human life, and it is one of the main pollution sources of water bodies. Mainly feces and washing sewage. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fatty protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, Potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus content, and the post-processing is relatively difficult. People should protect water resources. China's national con...
