System for microbial culture expanding and deep purification of micro-pollution water body

Abstract

The invention discloses a system for microbial culture expanding and deep purification of a micro-pollution water body. The system comprises a grille, a micro-nano bubble machine, a microbial cultureexpander and a microbial enhanced treatment area composed of gravels, clay and submerged plants. Bottom sediment, especially the organic pollutants in floating sediment, can be effectively reduced, the ecosystem of a polluted water body can be quickly repaired and rebuilt, the self-purification capacity of the water body can be improved, and water quality can be improved. The polluted water body is lifted to the upstream of a riverbed, sequentially passes through the grille, the micro-nano bubble machine and the microbial culture expander and is introduced into an assimilative water body afterfiltration, oxygenation and rapid microbial culture expansion. Gravels, clay and submerged plants are arranged in the assimilative water body to strengthen a microbial treatment effect, create a natural habitat and improve the level of biodiversity. The system can achieve the circulation treatment of the polluted water body and has the advantages of high efficiency, safety, wide application range, strong anti-pollution and impact property, and the pollutants in a river channel are natural nutrient sources for microbial culture expansion.

Description

technical field [0001] The invention relates to the technical field of micro-pollution remediation for water environment treatment and deep water quality improvement, in particular to a micro-polluted water depth purification system for microbial expansion and cultivation. technical background [0002] In the process of urbanization in my country, the problem of water pollution has become increasingly prominent. The destruction of the water ecosystem caused by water pollution, the reduction of the self-purification ability of the water body, the threat of eutrophication such as blue-green algae and Spirogyra, and the black and odorous phenomenon of the water body in severe cases, not only affect the urban environment, but also have a huge impact on the lives of surrounding residents. Since the "Water Pollution Prevention and Control Action Plan" was promulgated in 2015, according to the latest news from the National Urban Black and Odor Water Treatment Information Release Pl...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of in-situ expansion culture of microorganisms, which has no safety risk, high expansion efficiency, cyclic treatment of polluted water bodies, deep purification by means of contact oxidation and aquatic plant water ecological restoration, so as to solve the problem of existing water bodies The production cost is high, there are security risks, the repair effect is poor, and it is difficult to implement on a large scale.
