Method for treating black-odor rivers and lakes with microbiological preparations

Abstract

The invention pertains to the technical field of environment protection, which provides a method for treating black-odor rivers and lakes with microbiological preparations and comprises the following steps of: (1) pre-treatment of the rivers or the lakes; (2) biofilm colonization treatment; (3) microorganism augmentation treatment by direct application; (4) water ecology recovery and oxidation reduction of reductive sludge at the bottom; and (5) protection and further improvement of water environment. The method for treating black-odor rivers and lakes with microbiological preparations employs a plurality of microbiological preparations to treat the black-odor rivers and lakes, realizes the decomposition of organic pollutants in the water body, improves water ecological balance, and oxidizes, and reduces the reductive sludge at the bottoms of the rivers and lakes.

Description

technical field [0001] This technology belongs to the field of environmental protection technology, and specifically involves the application of various microbial agents to treat black and odorous rivers and lakes in cities, so as to decompose organic pollutants in water bodies, promote water ecological balance, and oxidize and reduce reducing sludge at the bottom Methods. Background technique [0002] Black and smelly rivers and lakes are a common phenomenon in my country's urban water networks, especially in the economically developed Pearl River Delta and Yangtze River Delta cities. The management of black and odorous rivers and lakes in my country's cities mainly adopts municipal measures such as sewage interception and dredging, and even covers the entire river with fine steel concrete; or uses irrigation to dilute, which not only wastes a lot of manpower, material resources, and financial resources , and often treat the symptoms but not the root cause, and fail to achi...

AI Technical Summary

Problems solved by technology

This application has the following disadvantages: First, the application divides the treatment steps according to the upper, middle and lower reaches of the river, and this application divides the treatment steps according to the time of water quality improvement, so it is completely different from the technical route of this application. The role of sewage storage is especially true for small and medium-sized cities in the south. The sewage outlets are distributed along the upper, middle and lower reaches of rivers. Moreover, the urban land is tight, and it is impossible to have large fish ponds, so the application will be difficult; second, the bioremediation application used The microbial preparation is not specific; third, the application uses suspended ball filler in the upstream oxidation pond, and the aerator is strongly aerated to make the microorganisms adhere to the filler, and the filler in the application is only suspended on the water surface
