Domestic sewage filtering and recycling integrated device

Abstract

The invention discloses a domestic sewage filtering and recycling integrated device, and the device comprises a sewage filtering device, wherein the sewage filtering device comprises a filtering tank, a standing box, a gravel filtering layer, an activated carbon filtering layer and a biochemical filtering layer, the filtering tank is fixedly connected to the top of one side of the standing box, the gravel filtering layer is installed in the filtering tank, the activated carbon filter layer is installed below the gravel filter layer, the biochemical filter layer is installed below the activated carbon filter layer, and a water outlet is formed in the end, away from the filter tank, of the standing box; a garbage filtering device which comprises connecting belts, a filter screen, guide wheels and a discharging plate, wherein the two connecting belts are fixedly connected to the two sides of the filter screen, the connecting belts and the filter screen are arranged between the two guide wheels in a sleeving mode, the two ends of the two guide wheels are rotationally connected to the side wall of the filtering tank, and a discharging opening is formed in the side wall of the filtering tank. According to the invention, a plurality of sewage treatment steps are simultaneously carried out, so that the sewage filtering and purifying efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water resource environmental protection, in particular to an integrated device for filtering and recycling domestic sewage. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to environmental protection. In people's lives, people generally discharge domestic sewage. Domestic sewage contains solid waste such as vegetable roots, soil, plastic bags, and particles such as feces. Small suspended garbage suspended in water also contains microorganisms such as Escherichia coli. Sewage treatment is an important part of water pollution control. In the process of sewage treatment, filtering sewage is an indispensable process. There is a large amount of solids in urban sewage, and most of them need to be removed before subsequent treatment. Filters are mainly used to remove solids. In the prior art, multiple filter screens are arranged in the filter ...

Problems solved by technology

[0003] However, in order to reduce the filtering burden of the filter device, before the domestic sewage treatment, the domestic garbage and waste water in the sewage are often separated, and the waste water is filtered. This method not only requires the cooperation of multiple devices, but also reduces Filtration efficiency of domestic sewage
