Embodiment 1

[0037] Example 1: Treatment of a middle drainage canal in Xiqing District, Tianjin

[0038] The industrial enterprises around the main canal discharge about 6,000 tons of industrial sewage and 9,000 tons of domestic sewage every day, and the pollution level of industrial sewage is very high. Adopt the processing method of polluted river of the present invention to control, concrete method is as follows:

[0039] (1) Detect the pollution indicators of the river,

[0040] (2) The type and quantity of the prepared bacterial agent,

[0041] (3) Put the obtained composite bacterial agent into the water body at 50-100ppm,

[0042] (4) The compound bacterial agent transfers, transforms and degrades the pollutants in the river,

[0043] (5) Detect the pollution indicators of the river;

[0044] (51) Repeat steps (2) to (5) until the river meets the requirements;

[0045] The weight ratio of the composite bacterial agent is as follows: 10-40 photosynthetic bacteria, 10-40 bacillus...

Abstract

The invention provides a method for treating a polluted river, which comprises the following steps: (1) detecting the pollution indexes of the river; (2) regulating the types and quantities of microbial agents; (3) putting a resulting composite microbial agent in a water body in an amount of 50 to 100 ppm; (4) allowing the composite microbial agent to transfer, covert and degrade pollutants in the water in the river; (5) detecting the pollution indexes of the river; and (6) repeating the steps from (2) to (5) till the river meets requirements. The microbial agents comprise photosynthetic bacteria, bacillus subtilis, nitrobacteria, lactic acid bacteria and yeasts. The method for treating the polluted river of the invention reduces and inorganizes pollutants in water in the river to treat the river and has the advantages of simple operation and low cost.

Description

technical field [0001] The invention relates to the technical field of ecological treatment, in particular to a treatment method for polluted rivers. Background technique [0002] The apparent characteristics of polluted rivers - black and smelly, are mainly caused by the enrichment of a large amount of nutrients imported from the outside in the water body. A large amount of pollutants are deposited to form silt. The pollutants in the water body consume the dissolved oxygen in the water body, and a large amount of good Oxygenous water body organisms began to die, while anaerobic microbial populations became very active, resulting in the production of hydrogen sulfide and other odors and many black metal sulfides, which destroyed the original ecosystem in the river channel and gradually deteriorated. Finally, the river lost its self-purification ability and gradually Become black and smelly. There are many factors affecting the governance of black and odorous rivers, and the...
