Embodiment 1

[0064] Figure 1-2 It shows an implementation of the bioelectric enhancement-based water restoration device of the present invention, which includes a housing 1 and a hollow part 3 disposed in the housing 1, both of which are PVC pipes.

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

[0066] Both the upper part and the lower part of the hollow part 3...

Embodiment 2

[0075] This embodiment shows another implementation of the water restoration device based on bioelectricity enhancement of the present invention. The hollow part in the shell, the shell and the hollow part are all 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 through the first through hole flows 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] The upper and lower parts of the hollow parts 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 of the second through hole is 0.8 cm.

[0078] The area between the casing and the hollow part forms an aerobic area, and...

Abstract

A water body remediation device based on bioelectricity enhancement comprises a shell, wherein a first through hole is formed in a side wall of the shell; and a hollow part, which is arranged in the shell; a second through hole is formed in the side wall of the hollow part; an aerobic area is formed in an area between the shell and the hollow part, an anaerobic area is formed in an internal hollowarea of the hollow part, a first electrode is arranged in the aerobic area, and a second electrode is arranged in the anaerobic area. The water body remediation device provided by the invention is ofa double-layer composite structure with the shell and the hollow part in the shell, thus achieving the integrated design of an aerobic area and an anaerobic area. The water body remediation device provided by the invention directly utilizes indigenous microorganisms to realize in-situ remediation of the polluted riverway water body, has higher denitrification efficiency, can effectively remove phosphorus and inhibit algae growth, and is a riverway water body long-acting remediation device with low cost investment.

Description

technical field [0001] The invention relates to the fields of sewage treatment and ecological restoration, in particular to a water restoration device based on bioelectricity enhancement. Background technique [0002] Urban waterways are an important part of urban ecosystems. Due to the influx 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 the restoration of polluted water is to eliminate organic and inorganic pollutants in the water, restore the ecology of the water and make it gradually self-purifying. Due to the high cost, ex-situ remediation is not suitable for the remediation of large-scale water bodies. Therefore, in-situ remediation is generally adopted for the treatment of river polluted water bodies. [0003] The in-situ treatment methods of water...
