Compound microbial agent for treating black and odorous bottom mud and its application

Abstract

The invention discloses a composite microbial agent for treating black and odorous bottom mud and application thereof. The active ingredients of the composite microbial agent for treating the black and odorous bottom mud provided by the invention consist of Ensifer morelensis, Paracoccus pantotrophus and Rhodococcus ruber. The active ingredients of the microbial agent for treating the black and odorous bottom mud provided by the invention are cultures obtained by culturing the composite microbial agent for treating the black and odorous bottom mud by using a culture medium. The invention alsoprovides a biological oxidation reactor containing the composite microbial agent for treating the black and odorous bottom mud and / or the microbial agent. The composite microbial agent for treating the black and odorous bottom mud, the microbial agent or the biological oxidation reactor has obvious oxidation effect on the black and odorous bottom mud, has organic matter removal rate obviously higher than that of single-bacterium treatment, can be used for treating and repairing the black and odorous bottom mud, and has good application prospect.

Description

technical field [0001] The invention relates to a compound microbial bacterial agent for controlling black and odorous bottom mud and its application. Background technique [0002] Black and odorous urban rivers, lakes, and ponds have become a common pollution problem in many large and medium-sized cities in my country, seriously affecting the lives of residents, the image of the city, and the ecological environment. However, the sediment sediment in rivers, lakes, and ponds often becomes the main source of pollutants due to years of accumulation, and anaerobic reactions are prone to occur in an anaerobic environment at the bottom of the water, which intensifies the release of pollutants into the water body, resulting in the generation of black odor. . Therefore, the control of black and odorous bottom mud is particularly critical for eliminating black and odorous sediments. [0003] At present, the commonly used methods mainly include physical dredging, etc., but due to t...

Problems solved by technology

[0003] At present, the commonly used methods mainly include physical dredging, etc., but due to the huge amount of dredging works, it has disadvantages such as high investment and long construction period, and the bottom sludge from dredging needs to be treated separately, which needs to be improved urgently.
