Microorganism dredging method and device

Abstract

The invention provides a microorganism dredging method. The microorganism dredging method is characterized in that a microbial preparation is implanted in sludge at the bottom of a river channel, the implanting position is 10-15cm far away from the upper layer of the sludge, and the microbial preparation is dredging bacteria which takes porous zeolite particles as carriers, is added with peroxide and contains live bacteria including bacillus subtilis, desulfurizing microorganisms H1-H4, phosphorus accumulation organisms, nitrifying bacteria and denitrifying bacteria which are in proportion. A dredging device comprises a fixed support, a rack and a microorganism implantation groove, wherein the bottom of the rack is provided with a bottom flat plate with a hole, a feed port is formed in the upper part of the microorganism implantation groove, a discharge port is formed in the lower part of the microorganism implantation groove, and an implantation mechanism is arranged in the microorganism implantation groove. The dredging device is used for implanting the microbial preparation in the sludge at the bottom of the river channel, so that microorganisms realize aerobiotic and anaerobic metabolism in anaerobic and facultative aerobic environments and transform matters such as sulfide, nitrite and organic matters in the sludge through microorganism cell metabolism, thus a biological dredging effect is achieved.

Description

technical field [0001] The invention relates to a microbial dredging method and a device thereof. Background technique [0002] The traditional river dredging method is the manual mechanical method, which requires a large investment in manpower and material resources, and the transfer of pollutants will cause secondary pollution; although the short-term effect is obvious, the manual mechanical method cannot fundamentally solve the problem of river silt. After a certain period, the dredged river Re-filling with silt will cause a waste of manpower and material resources, and will completely destroy the ecological environment of the river, which will be difficult to restore in a short time. [0003] Recently, the microbial dredging method has gradually become popular, and it is increasingly used in river dredging projects. However, the success of microbial desilting depends on the ability of microbial preparations and the process of using microorganisms. Generally, microbial ...
