Abstract

The invention discloses a compound microbial agent. The compound microbial agent is prepared from nitrophilous rhizobium ATCC 35116 culture, trichoderma longibrachiatum AS3.1029 culture and acremoniumATCC 48379 culture. By culture solution prepared by mixed culture of the nitrophilous rhizobium ATCC 35116 culture, the trichoderma longibrachiatum AS3.1029 culture and the acremonium ATCC 48379 culture, the compound microbial agent has an excellent treatment effect on sewage mineral fertilizers, various organics, colloids, macromolecular substances such as sugars and organic acids, and the like,and accordingly effectiveness in domestic sewage purification treatment is realized.

Description

technical field [0001] The invention relates to a microbial bacterial agent and its preparation method and application, in particular to a composite microbial bacterial agent for heavy metal wastewater treatment and its preparation method and application. Background technique [0002] At present, the discharge of urban domestic sewage is the main pollution source of urban water in my country, and the treatment of urban domestic sewage is the top priority of urban water conservation and urban water environment protection at present and in the future. Domestic sewage is the sewage generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter, including: floating and suspended solid particles of large and small sizes, colloidal and gel-like diffusers, and pure solutions. [0003] In the prior art, when using compound microbial bacterial agents to treat domestic sewage, bacterial agents and biological enzymes are often used to decomp...
