Treating method of river bottom mud

Abstract

The invention provides a treating method of river bottom mud, comprising the following steps: (1) detecting pollution indexes of river bottom mud; (2) blending the varieties and the numbers of microbial agents; (3) throwing the obtained composite microbial agents into a water body according to 150ppm to 300ppm; (4) transferring, translating and degrading pollutants in the river bottom mud by the composite microbial agents; (5) detecting the pollution indexes of the river bottom mud; and (6) repeating the steps from (2) to (5) until a river conforms to requirements. Each composite microbial agent comprises the components by weight percent: 60 to 80 photosynthetic bacteria, 60 to 80 nitrifying bacteria, 30 to 40 lactobacillus and 30 to 40 microzyme. The processing method of river bottom mud reduces and enables the pollutants of the river bottom mud to be inorganic, thereby cutting sludge and achieving the effect of processing the river bottom mud in situ.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a treatment method for river bottom mud. 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 go...

Problems solved by technology

[0004] For river bottom mud, dredging is the most widely used. River dredging requires a lot of manpower, material and financial resources, and requires a long construction period. Silt will cause secondary pollution during transportation and storage, and dredging It cannot solve the fundamental problem, and it will also destroy the natural ecology of the original river, so that the indigenous biological population in the bottom mud will be lost with dredging, thereby reducing the self-purification ability of the river water body
