Embodiment 1

[0064] Figure 1-2 An implementation of the bioelectric enhancement-based water body repairing device of the present invention is shown, which includes a casing 1 and a hollow part 3 arranged in the casing 1, and both the casing 1 and the hollow part 3 are PVC pipes.

[0065] The side wall of the casing 1 is provided with a first through hole 18. In this embodiment, the first through hole 18 is a circular hole, so as to realize the dynamic exchange between the sewage in the casing 1 and the sewage outside the casing 1. The inner diameter of the casing 1 is 20 cm, the height is 50 cm, the porosity of the side wall of the casing 1 is 45%, and the diameter of the first through hole 18 is 0.5 cm. The upper part of the casing 1 has an opening, so that the sewage entering the inside of the casing from the first through hole 18 flows out from the upper opening, so as to realize the circulating flow of sewage in the casing 1 and outside the casing 1 .

[0066] Both the upper and lowe...

Embodiment 2

[0075] This embodiment shows another implementation of the bioelectric enhancement-based water body restoration device of the present invention. The main structure is similar to that in Embodiment 1 (so it is not shown in the drawings), which includes a casing and a The hollow part in the shell, the shell and the hollow part are PVC pipes.

[0076] The side wall of the casing is provided with a first through hole, and the upper part of the casing has an opening, so that the sewage entering the inside of the casing from the first through hole can flow out from the upper opening. The inner diameter of the casing is 40 cm, the height is 60 cm, the porosity of the side wall of the casing is 60%, and the diameter of the first through hole is 1.0 cm.

[0077] Both the upper and lower parts of the hollow part are sealed to maintain an anaerobic environment. The inner diameter of the hollow member is 12 cm, the height is 60 cm, the porosity of the side wall is 40%, and the diameter o...

Abstract

A water restoration device based on bioelectricity enhancement, comprising: a casing, the side wall of which is provided with a first through hole; and a hollow part, which is arranged in the casing, and the hollow part The side wall is provided with a second through hole; the area between the housing and the hollow part forms an aerobic area, and the inner hollow area of ​​the hollow part forms an anaerobic area, and the aerobic area is provided with a first An electrode, a second electrode is arranged in the anaerobic region. The water body restoration device provided by the invention is a double-layer composite structure with a shell and a hollow part inside the shell, and realizes the integrated design of an aerobic area and an anaerobic area. The water restoration device provided by the present invention directly uses indigenous microorganisms to realize the in-situ restoration of polluted river water, has high nitrogen removal efficiency, and can effectively remove phosphorus and inhibit algae growth at the same time. Repair device.

Description

technical field [0001] The invention relates to the field of sewage treatment and ecological restoration, in particular to a water body restoration device based on bioelectricity enhancement. Background technique [0002] Urban watercourses are an important part of urban ecosystems. Due to the inflow of industrial wastewater, domestic sewage and agricultural runoff, the river water body is deteriorating day by day. Black and odorous water bodies and frequent algal blooms have become the main problems of water pollution in some areas of my country. The essence of polluted water remediation is to eliminate organic pollutants and inorganic pollutants in the water body, restore the water body ecology and gradually make it self-purifying. Due to the high cost, ex-situ restoration is not suitable for the restoration of large-scale water bodies. Therefore, the current treatment of river polluted water bodies generally adopts in-situ restoration. [0003] The in-situ treatment me...
