Ecological treatment method for black and odorous water body

Abstract

The invention discloses an ecological treatment method for black and odorous water body. According to the ecological treatment method, metabolism capability of microorganisms and the diversity of genes are utilized; pollutants are converted into pollution-free final products for entering into the biogeochemical cycle again; meanwhile, due to the introduction of microorganisms, the biological diversity in water can be increased; all levels of nutrition structures of the water body are improved to be stable and balance is kept. Compared with physical method, migration method and chemical method,the advantages of the invention scheme are that: the conversion process of pollutants can be efficiently and relatively thoroughly completed under mild conditions, the treatment cost is low, the application range is wide, the influence on the environment is small, secondary pollution is avoided, the impact resistance of microorganisms is high, the tolerance to harmful environments such as toxic and harmful substances is high, and in-situ self-renewal can be achieved; repeated adding is not needed, long-term use can be achieved through one-time adding, the effect of rapid and efficient sewagedisposal is achieved, the water environment is effectively improved, and the water self-purification function is completely repaired and restored.

Description

technical field [0001] The invention relates to the technical field of environmental protection, more specifically to the field of sewage treatment, in particular to an ecological treatment method for black and odorous water bodies. Background technique [0002] With the acceleration of industrialization, the problem of environmental pollution is becoming more and more serious. The indiscriminate discharge of wastewater generated in industrial production is the main cause of river and water pollution, and the restoration of polluted water is imminent. Currently, the restoration of industrially polluted water mainly uses Putting in chemical agents and physical filtration and other combined treatment, throwing flocculants to combine pollutants and flocculants to precipitate, and then use physical filtration to filter the flocs to improve water quality; or plant aquatic plants with strong vitality for ecological purification, Such as water hyacinth and so on. [0003] However,...

AI Technical Summary

Problems solved by technology

[0003] However, industrially polluted water bodies are often black, odorous and eutrophic water bodies with complex components, and it is difficult to completely purify and repair them with a single treatment technology, and the addition of chemical agents needs to be strictly controlled to avoid secondary pollution. Pollution, the most important thing is that the cost of chemical treatment is high and the treatment effect is not long-lasting. It cannot achieve both symptoms and root causes to restore the self-regulation function of the water body; and in the process of aquatic plant treatment, due to the strong adaptability of the plant, it is easy to grow wildly, affecting the principle of the water body. It has functions, and the decay of plants will also increase the eutrophication of the water body, and cannot restore the self-healing of the water body
