Sewage treating and recycling equipment

Abstract

The invention discloses sewage treating and recycling equipment. The sewage treating and recycling equipment comprises a pressure dissolved air vessel, an air floating tank, a precipitation filtration chamber, an ozone sterilizing chamber and a recycling tank. The outer surface of the pressure dissolved air vessel is connected with a water storage tank in the air floating tank through a second water pipe. A third guide pipe is arranged inside the water storage tank, extends out of the air floating tank and is connected to the top of the precipitation filtration chamber. The sewage treating and recycling equipment has the advantages that the air floating tank is connected with the outer surface of the pressure dissolved air vessel to form a total-dissolution air floating system, so that the problem of poor decontamination ability is solved; the filtration chamber is provided with a filter screen and an activated carbon layer, so that the problem of poor sludge settleability is solved; the equipment is provided with the ozone sterilizing chamber and an ultraviolet sterilizing lamp, so that the problem of poor sterilizing effect is solved; the outer surface of the recycling tank is a protruded hexagon, so that materials are saved and area is increased; the equipment is provided with a water quality detector, so that the problem that traditional equipment cannot detect treated water and cannot give an alarm timely is solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to sewage treatment and reuse equipment. Background technique [0002] Modern sewage treatment technology can be divided into physical treatment method, chemical treatment method and biological treatment method according to the principle. The physical treatment method is to separate and remove the insoluble suspended pollutants in the wastewater through physical action (the method mainly includes the screening method, the precipitation method, the air flotation method, the filtration method and the reverse osmosis method, etc.; the chemical treatment method is The treatment methods for separating pollutants in sewage by chemical reaction mainly include neutralization, electrolysis, redox and electrodialysis, gas lift, adsorption, stripping, extraction and other methods, which are generally applicable to industrial sewage treatment; biological treatment is the use of The me...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional sewage treatment equipment has poor decontamination ability, and the sludge settleability is not good. The sterilization effect of the general equipment is not good, resulting in poor water quality. The recovery tank of the existing sewage treatment equipment is rectangular. The use of materials is increased, and the effective area cannot be maximized. Traditional equipment lacks the detection of treated water sources, and cannot detect the quality of treated water in a timely manner.
