Abstract

The invention provides a microbial inoculant used for treatment of municipal sewage. The microbial inoculant is composed of bacterial powder A, bacterial powder B, bacterial powder C and auxiliary materials, wherein the bacterial powder A contains lactic acid bacteria, bacillus subtilis, blue-green algae, saccharomycetes and trichoderma; the bacterial powder B contains Nocard's bacillus, streptomycetes, thermophilic actinomycetes, aspergillus niger and chaetomium globosum; the bacterial powder C contains aspergillus, bacillus cereus, rhizobium, bacillus flexus and pseudomonas; the auxiliary material A is composed of dipotassium phosphate, potassium dihydrogen phosphate and sodium chloride; the auxiliary material B is composed of polyaluminium chloride, sodium lignin sulfonate and sodium laurate. The inoculant is used for treatment of municipal sewage, the microbes are reasonably mixed, the municipal sewage can be treated to form water conforming to the primary emission standard within three days, and no environmental pollution is caused during the treatment process.

Description

technical field [0001] The invention relates to a microbial bacterial agent, in particular to a microbial bacterial agent for urban sewage treatment. Background technique [0002] Urban sewage is a general term for sewage discharged into urban sewage systems. The combined sewerage system also includes production wastewater and intercepted stormwater. Urban sewage mainly includes domestic sewage and industrial sewage, collected by the urban drainage pipe network and transported to sewage treatment plants for treatment. Sewage resulting from the confluence of urban sewage, industrial wastewater and urban runoff sewage. [0003] More than 90% of urban sewage is water, and the rest is solid matter. Water generally contains the following pollutants: [0004] Suspended solids: generally 200~500 mg / L, sometimes more than 1000 mg / L. Among them, inorganic and colloidal particles are easy to adsorb organic poisons, heavy metals, pesticides, pathogenic bacteria, etc., forming comp...
