Mobile device for treating, recovering and reusing sewage

Abstract

The invention relates to a mobile device for treating, recovering and reusing sewage, comprising an air flotation tank, a residue scraping mechanism and a water returning mechanism. The upper part and the lower part of the air flotation tank are respectively provided with a water outlet and a water inlet; the top of the air flotation tank is provided with the residue scraping mechanism, and the bottom is provided with an air inlet and a residue discharging opening; aeration heads are laid on the inner bottom of the air flotation tank, and four pin wheels are arranged on the bottom end of the air flotation tank; scraping plate belts are equidistantly arranged on a bendable circumferential belt-shaped body by a plurality of scraping plate and are sleeved between an axial wheel of a residue scraping motor and a driven wheel; the pendulous parts of the scraping plate belts are immersed in liquid in the air flotation tank; the residue scraping motor and the driven wheel are respectively arranged on the right side and the left side of the top of the air flotation tank; the distance between the driven wheel and the residue scraping motor can be adjusted; the upper part of a filter is provided with a water inlet, and the lower part is provided with a water outlet; activated carbon is filled in the filter; the water outlet of the air flotation tank is connected with the water inlet of the filter; the water outlet of the filter is connected with the return water inlet of a return water pump; and the return water outlet of the return water pump is connected to an external water tank or water pipe. The mobile device for treating, recovering and reusing sewage can move and has obvious sewage treatment and purification effect.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a movable device for on-site treatment and recycling of sewage. Background technique [0002] In the process of environmental governance, the task of sewage treatment is very large, especially oily sewage. It is a difficult problem to solve both in terms of discharge volume and treatment technology. If the treatment is not good, a large amount of toxic and harmful substances Discharging into rivers and farmland will damage the environment, affect agricultural production, and may seriously pollute drinking water. Therefore, the treatment of oily sewage is often regarded as an important project in environmental governance. [0003] If each sewage tank is equipped with sewage treatment equipment, it is not very modern, because capital and land occupation are big problems that are difficult to solve. When there is a lot of oil on the liquid surface, the usual method is to throw straw bale...
