A method for in-situ natural purification of black and odorous water

Abstract

The invention discloses a method for in-situ natural purifying of a black odor water body. The black odor water body flows along a river channel, the method comprises the following steps: a quantum effect ecological network can be spread in the river channel to form a quantum effect ecological unit; and the high-efficiency composite microbial liquid is regularly fed to the black odor water body toform a composite microbial unit; a biological purification unit is disposed at the bottom of the river channel, and the biological purification unit comprises a biological purification bed and microorganisms attached to the biological purification bed for degrading the sludge of the river channel; aeration devices are arranged in a front section, a middle section and a rear section of the river channel to form a water flow exchange unit for disturbing the water body at the bottom and surface of the river channel to increase the oxygen content of the water body; and a water ecological regulation unit is arranged at the river channel to reconstruct and balance a water ecosystem. The method utilizes the synergistic action of a plurality of units to treat the black odor water body, and constructs the water ecosystem, so that the water body can realize the self-cleaning function, the method prevents the water body from recovering pollution, and the treatment effect is good.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a method for naturally purifying black and odorous water in situ. Background technique [0002] With the development of social productivity, my country's water environment pollution is becoming more and more serious, and rivers and lakes are generally polluted. Relevant data show that 75% of lakes have eutrophication to varying degrees, and 90% of urban waters are seriously polluted, further exacerbating water pollution. shortage of resources. A large amount of domestic sewage, industrial sewage, aquaculture sewage and agricultural sewage are discharged into rivers every day due to life and production in various industries, which has a serious negative impact on the improvement of residents' lives and the implementation of sustainable economic development strategies. The large flow of sewage around the river and the complexity of the geographical environment make it impossible to c...

Problems solved by technology

The disadvantage is that the purification rate is slow, the floor area is large, it affects the flood control safety of the river, there is a risk of secondary pollution, and the replacement of fillers and the harvesting and processing of plants are relatively expensive.
