Description
Technical Field
The invention relates to the field of sewage treatment, in particular to an activated microorganism activation and propagation system and an activated microorganism propagation method for sewage treatment.
Background
According to the 'urban black and odorous water body regulation working guideline' issued by the ministry of construction of housing and urban and rural areas of China, the urban black and odorous water body is a general name of water bodies which present unpleasant colors (black or blackish) and/or emit unpleasant smells (smells or smells) in the built-up areas of cities. The mechanism of blackening water is mainly divided into two types: an insoluble substance present in a water body in a solid state or in a form adsorbed on suspended particles; the other is organic compound with color humus dissolved in water. Researches show that humic acid and fulvic acid in suspended particles in water adsorb and complex compounds of iron, manganese and sulfur, which are main chemical substances for blackening the water, and indicate that Fe2+Plays a dominant role in the blackening process. Iron exists mainly in the form of oxides and hydroxides in nature, along with a large amount of organic pollutants entering a water body, aerobic microorganisms consume a large amount of oxygen content in the water body, so that the whole water body exists in an anoxic reduction state, and at the moment, iron elements are reduced to form a large amount of Fe2+. Meanwhile, sulfur mainly enters the water body in the form of organic sulfur and sulfate, the organic sulfur is decomposed to form hydrogen sulfide due to serious oxygen deficiency of the water body, and the sulfate forms S under the reduction action of sulfate reducing bacteria2-. A large amount of accumulated ferrous ions and S2-The FeS is formed by combination and enters the water body under the influence factors of hydraulic flushing and the like, so that the water body is blackened.
In an anoxic water body, organic pollutants can generate a large amount of odorous substances such as hydrogen sulfide, ammonia, amine, mercaptan and the like under the anaerobic degradation of anaerobic microorganisms. The acid hydrolysis products of humic acid and fulvic acid form a large amount of odorous ammonia gas and extremely odorous thioether compounds after a series of biochemical reactions. When a large amount of actinomycetes exist in water, mercaptan and thioether substances generated by anaerobic decomposition of sulfur-containing protein can be utilized to carry out biological metabolism to generate 2-methylisothianol and oxytetracycline with odor. In addition, odorous substances such as beta-ionone (aldehyde) and the like can be formed after the death and cracking of the algae, and the water body environment is seriously influenced, so that the water body treatment is not slow at all. At present, two sewage treatment modes mainly comprise a chemical preparation and a microbial preparation, wherein the microbial preparation is favored because the microbial preparation can not cause secondary pollution to a water body. At present, when the microbial preparation is used for treating sewage, exogenous microbes are generally added, and when the treated section is an upstream river channel section of a living area, downstream residents of the treated section often have greater worry and conflict psychology.
Disclosure of Invention
The invention aims to provide an activated microorganism activation propagation system and an activated propagation method for sewage treatment, which can effectively enrich and proliferate local target microorganisms in a river channel by automatically adjusting propagation conditions.
