Biological microbial inoculum culture and adding device for in-situ remediation of micro-polluted water body

Abstract

The invention discloses a biological microbial inoculum culture and adding device for in-situ remediation of micro-polluted water body. The device comprises a stainless steel container, an ultraviolet sterilization system, a microbial inoculum circulatory culture system, a microbial inoculums adding system and a buoyancy stability control system; raw water from a water source is subjected to asepsis by the ultraviolet sterilization system and then flows into the stainless steel container; an appropriate amount of bacterial liquid is added into the stainless steel container at the same time; an additional carbon source is not required in the culture process, and original nutrients in the raw water are fully used as the nutrients required by bacterial culture; dissolved oxygen concentrationrequired by the microbial inoculum culture process is met by starting the microbial inoculum circulatory culture system; the microbial inoculum circulatory culture system accelerates the microbial inoculum culture process through stirring function per se; the microbial inoculums adding system is started to add the biological microbial inoculum into the water body to be treated; and the stability of the device in water is ensured by starting the buoyancy stability control system at the same time. The device has the advantages of compact structure, flexible use, easy movement, investment conservation and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and relates to a biological bacterial agent culturing and dosing device for in-situ restoration of micro-polluted water bodies. Background technique [0002] Eutrophication is a water quality problem faced by many lakes and reservoirs in my country. Reservoir eutrophication and the proliferation of algae lead to a significant increase in organic matter, chromaticity and abnormal smell in water, which not only affects various functions of water bodies and water quality indicators, but also affects water quality. destroy the ecological balance of water bodies. Therefore, various water restoration technologies have emerged. In situ bio-injection technology has the advantages of no additional carbon source and special treatment structures, low investment, low operating cost, simple operation and basically no side effects. It is an economical and effective biological nitrogen removal t...

AI Technical Summary

Problems solved by technology

However, in the in-situ bioremediation of slightly polluted water, there is a problem of poor organic nutrition, and it is difficult for general microbial agents to play a role, so the water purification effect is not ideal.

In addition, the research on the in-situ bio-injection technology of micro-polluted water is still in the laboratory research stage, and there is a lack of special biological agent cultivation and dosing devices in practical engineering applications. The report of the biological agent culture and dosing device
