Method for digesting bottom mud of black and odorous river channel through microorganism preparation

Abstract

The invention relates to the field of pollution management and discloses a method for digesting bottom mud of black and odorous river channel through a microorganism preparation. The microorganism preparation is added into a black and odorous river channel; the microorganism preparation is prepared by mixing CQ1, CQ2 and CQ3 according to the volume ratio of (1 to 3) to (1 to 3) to 1; the CQ1 is amixed bacterium agent of bacillus subtilis, bacillus aureus, acinetobacter, psychrobacter, acinetobacter and pseudomonas strains; the CQ2 is a mixed bacterium agent of arcobacter, acinetobacter and shewanella oneidensis strains; and the CQ3 is a mixed bacterium agent of aeromonas, ralstonia eutropha and ralstonia eutropha strains. By adopting the method disclosed by the invention, the problems that original biological population structures and living conditions of rivers and lakes are damaged in a traditional dredging manner, a self-cleaning function is weakened so that negative influences onecological restoration are caused and secondary pollution is easy to cause, principal and secondary aspects cannot be treated at the same time, people are likely to be disturbed and the management price is high are solved.

Description

technical field [0001] The invention relates to the field of pollution control, in particular to a method for dissolving black and odorous river bottom mud with microbial preparations. Background technique [0002] Black and smelly river course means that the physical and chemical environment in the river course is strongly reducing, the organic and inorganic pollution is extremely serious, the water body has peculiar smell, it is no longer suitable for aquatic organisms to survive, the aquatic vegetation is degraded or even extinct, and there are only a few phytoplankton, zooplankton and benthic animals Stain-tolerant species exist. At present, black and smelly rivers are a common phenomenon in urban river networks in my country. Due to social and economic development, a large amount of industrial wastewater and domestic sewage without effective treatment are discharged into urban rivers and lakes, causing water environmental pollution. Black and odorous rivers and eutroph...

Problems solved by technology

[0009] The present invention intends to provide a method for microbial preparations to digest black and odorous river bottom mud, so as to solve the problem that the traditional dredging method destroys the original biological population structure and habitat of rivers and lakes, weakens their self-purification function, and has a negative impact on ecological restoration, which is easy to cause The problem of secondary pollution
