Embodiment 1

[0033] Example 1: Treatment of a middle drainage channel

[0034] 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 purification method of polluted river of the present invention to control, and concrete method is as follows:

[0035] (1) Detect the pollution indicators of the river,

[0036] (2) Intercept sewage from rivers,

[0037] (3) The type and quantity of the bacterial agent to be prepared,

[0038] (4) put the obtained composite bacterial agent into the water body by 60-120ppm,

[0039] (5) The compound bacterial agent transfers, transforms and degrades the pollutants in the river,

[0040] (6) Detect the pollution indicators of the river;

[0041] (61) Repeat steps (3) to (6) until the river meets the requirements;

[0042] The parts by weight of the composite microbial agent are: 50-80 photosynthetic b...

Abstract

The invention provides a method for purifying a polluted river, comprising the following steps: (1) detecting pollution indexes of a river; (2) intercepting sewage of the river; (3) blending the varieties and the numbers of microbial agents; (4) throwing the obtained composite microbial agents into a water body according to 60ppm to 120ppm; (5) transferring, translating and degrading pollutants in the river by the composite microbial agents; (6) detecting the pollution indexes of the river; and (61) repeating the steps from (3) to (6) until the river conforms to requirements. Each composite microbial agent comprises the components by weight: 50 to 80 parts of photosynthetic bacteria, 60 to 70 parts of bacillus subtilis, 60 to 70 parts of nitrifying bacteria, 25 to 30 parts of lactobacillus and 25 to 30 parts of microzyme. The method for purifying a polluted river reduces the pollutants of the water body of the river and enables the pollutants of the water body of the river to be inorganic, initially processes the river and has simple operation and low cost.

Description

technical field [0001] The invention relates to the technical field of ecological treatment, in particular to a method for purifying 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...
