Microorganism expanding culture device for water environment treatment

Abstract

The invention provides a microorganism expanding culture device for water environment treatment. The microorganism expanding culture device comprises an equipment shell, an automatic quantitative microbial agent adding system, a raw water quality filtering and disinfecting system, a clear water supply system, a microbial agent constant-temperature culture system and an automatic control system, the microbial agent automatic quantitative adding system, the raw water quality filtering and disinfecting system and the clear water supply system are all connected with the microbial agent constant-temperature culture system through pipelines; the automatic control system is provided with an operation control program and operation requirements in advance. According to the invention, the effective flora to be supplemented and added into the water body is subjected to enlarged culture by controlling key environmental factors such as temperature, dissolved oxygen and the like which influence microbial proliferation, so that under the condition of the same dosage of the microbial agent, the number and the biological activity of the effective flora added into the water body are increased, and the treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of water environment treatment, in particular to a microorganism expansion cultivation device for water environment treatment. Background technique [0002] With the continuous improvement of the urbanization level, the urban water environment is more and more significantly affected by the urbanization process, and more and more urban pollutants are discharged into urban rivers, resulting in increasing urban water pollution and seriously affecting urban water quality. Environmental quality and the healthy life of residents. Water body microbial remediation technology is to improve the degradation ability of water body indigenous microorganisms or exogenous microorganisms to pollutants by adding microbial reagents or (and) nutrient elements, etc. The process of gradually restoring water quality. This technology does not need to build structures in the water body, and can "in situ" remove river water polluti...

Problems solved by technology

[0004] However, there are few special equipments for this method at present, and only simple mixing of bacterial agents and sediments is used. Due to environmental factors such as temperature and dissolved oxygen, precise control cannot be achieved, and other microorganisms contained in the sediments will interact with the added microbial agents. Effective microorganisms compete for nutrients, resulting in low efficiency of secondary culture of microorganisms, making it difficult to achieve the optimal level of treatment effect
