Problems solved by technology

At present, the construction of my country's urban sewage pipe network is not perfect. In quite a few areas, especially in the urban-rural fringe, there is still a large amount of rain and sewage confluence and even untreated sewage directly discharged into the river, and the sewage discharge points of this part are relatively scattered. , cannot be treated in a concentrated manner, so the current biological contact oxidation sewage treatment facilities cannot play their due role well

Embodiment Construction

[0020] The frame-type biocontainment and decontamination grid provided by the present invention is composed of four basic units, figure 1 It is a preferred embodiment of the present utility model. As shown in the figure: it mainly includes a frame 1, a dirt-holding layer 2, a decontamination chamber 3 and a suspension 4. Wherein, the frame 1 is made up of hard materials such as hollow galvanized iron pipes or plastics, and is made of two independent fences that can be opened on one side. There is a certain space (20-50cm, depending on the needs) between the two fences. ), length * width * height is 100cm * 50cm * 100cm (depending on needs), and the effect of frame 1 includes fixing the pollution-reducing material and giving the decontamination room to be fixed space. The dirt-holding layer 2 is fixed in an independent fence, and its main material is sponge with a thickness of about 5cm. The sponge has a large surface area, and the microorganisms in the sewage reproduce on th...

Abstract

The frame-type biological pollutant holding and eliminating grating for purifying dispersively drained contaminated water consists of four basic units, including frame, pollutant holding layer, pollutant eliminating chamber and suspension. It is made of physical materials, including galvanized iron tube or plastic for the frame, sponge for the pollutant holding layer, artificial polyethylene root,rope and hanger for the pollutant eliminating chamber, and foamed polyethylene, plastic coated cloth and rope for the suspension. It is used in treating dispersed city sewage in the river and has high treating efficiency, low construction cost, low running cost and low power consumption.

Description

Technical field: [0001] The invention relates to a device specially used for treating polluted water bodies discharged from scattered discharge of point source sewage or combined rain and sewage sewage into rivers and other waters, in particular to a frame-type bio-containment and decontamination grid for purifying polluted water bodies. Background technique: [0002] The biochemical treatment of sewage is to use various microorganisms existing in nature to decompose organic pollutants in sewage, so that sewage can be purified. Among them, the biological contact oxidation method is to use the biofilm fixed on the filler to absorb the organic matter in the sewage, oxidize and decompose it, and purify the sewage. This method has the unique advantage of good and stable effluent quality, but this method needs to properly concentrate the sewage before it can be treated, and it needs to occupy a certain site, and the infrastructure investment is relatively large. At present, the ...
