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 uppe

Embodiment Construction

[0036] Below in conjunction with embodiment content of the present invention is described in further detail

[0037] This example is for a river in a certain city. The river flows through villages A, B, and C, and finally flows into a tributary of the Dongjiang River. The total length of the river is about 8.5km, the water depth is 0.5-2.5m, the sludge is 60-150cm, the average width is 9m, and the total area is 7.65×10 4 m 2 , about 110 mu; total volume 1.14×10 4 m 3 .

[0038] The river surge is affected by the tidal action, the water volume changes greatly, and the water quality is complicated. The flow rate at the gate is 5m / min, and the flow rate is 55,000m 3 / d, there are high and low tides twice a day.

[0039] The residential quarters and factories on both sides of the river are relatively dense, and there are hundreds of sewage outlets, large and small. The pollutant composition is relatively complex, with about 12300m 3 The external sewage is directly discharged...

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...
