Problems solved by technology

[0005] However, in the actual restoration process of the river channel, the carrier is usually prone to float under the impact of the water flow, which reduces the contact area between the carrier and the water body and reduces the restoration effect of the river channel water body.

Embodiment 1

[0048] A kind of fixed microbial filter wall, see figure 1 , including several filter units 1 connected in series along the width of the river channel 3 and several fixing components 2 for fixing the filter units 1 in the river bed, so that the water body in the channel 3 passes through the filter wall vertically along the horizontal plane.

[0049] see figure 2 Each filter unit 1 includes an artificial floating bed 11 floating on the river surface, a carrier assembly 12 suspended below the artificial floating bed 11 and attached with dominant bacteria, and an aeration assembly 13 . The dominant bacterium in the present invention is selected from Zhongyibao brand national invention patent ZL200610060895.3 microbial agent. The microorganisms in the microbial agent rely on mutual synergy to form a micro-ecosystem with complex composition and stable structure. Through continuous value-added, Oxidize and decompose the organic pollutants in the water body to achieve the purpose o...

Embodiment 2

[0064] Embodiment 2: The difference from Example 1 is that the dominant bacteria select the microbial agent of Zhongyibao National Invention Patent ZL201210047274.7. The organic pollutants are reduced and degraded, which has obvious effect of river channel restoration.

Abstract

The invention discloses a fixed microbial filter wall, which belongs to the technical field of microbial treatment of river pollution, and comprises a plurality of filter units connected in series and a plurality of fixed components for fixing the filter units. The filter unit includes an artificial floating bed floating on the river surface and a carrier assembly suspended under the artificial floating bed and attached with dominant bacteria, the top of the carrier assembly passes through the artificial floating bed and is connected with a support frame fixed on the top of the artificial floating bed. The present invention stably fixes the filter component on the riverbed of the river through the fixing component and the support frame, and the dominant bacteria cells are fixed in the carrier component intact, so that it can still stably exert the repair performance in complex environments and intense operations , improve the restoration efficiency of the river water body, and at the same time reduce the cost of river restoration.

Description

technical field [0001] The invention belongs to the technical field of microbial treatment of river channel pollution, in particular to a fixed microbial filter wall. Background technique [0002] The remediation of polluted surface water is an environmental protection issue that has only received widespread attention in recent years. With the development of biotechnology, microbial treatment of sewage has become more and more popular to solve the problem that conventional remediation methods are difficult to play an efficient role. [0003] At present, the commonly used methods of microbial treatment of sewage include activated sludge method and biofilm method, mainly through the construction of large-scale sewage treatment plants to centrally treat water bodies polluted by organic matter. However, if such methods are used to treat surface water bodies with relatively low concentrations of organic pollutants, there will be a series of problems such as transportation difficu...
