Sewage treatment device

Abstract

The invention belongs to the field of sewage treatment equipment, and particularly relates to a sewage treatment device. The sewage treatment device comprises a filtering pond and an adsorption gasifying pond, wherein the filtering pond is connected with the adsorption gasifying pond through a water outlet pipe; a water pump is arranged on the water outlet pipe; the filtering pond is divided into a grating chamber and a settling chamber by a partition; the grating chamber is arranged above the settling chamber and communicates with the settling chamber through a connecting tube; a water inlet tube is arranged above the grating chamber; a water inlet valve and a water flow meter are arranged on the water inlet tube; one end of the water outlet pipe extends into the settling chamber while the other end of the water outlet pipe extends into the top of the adsorption gasifying pond; the end, which extends to the adsorption gasifying pond, of the water outlet pipe is provided with a spraying rod; and a sprayer is arranged on the spraying rod. After being treated by the sewage treatment device, the sewage can reach the standard of reuse of reclaimed water, and the treatment effect is good.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, and in particular relates to a sewage treatment device. Background technique [0002] China is a country short of water. Sewage treatment and reuse are effective measures to develop and utilize water resources. Sewage reuse is to treat urban sewage and industrial sewage through membrane bioreactors and other equipment, and then use them for greening, washing, Supplementing ornamental water and other non-drinking purposes. At present, in the water treatment industry, membrane bioreactors are put into large-scale practical applications. According to whether the membrane bioreactor needs oxygen, it can be divided into aerobic and anaerobic membrane bioreactors. Membrane bioreactors are generally used for urban and industrial treatment. Aerobic MBR is used for urban sewage treatment, usually for the purpose of reusing the effluent. Although the MBR process can effectively separate muddy wate...

[0002] China is a country short of water. Sewage treatment and reuse are effective measures to develop and utilize water resources. Sewage reuse is to treat urban sewage and industrial sewage through membrane bioreactors and other equipment, and then use them for greening, washing, Supplementing ornamental water and other non-drinking purposes. At present, in the water treatment industry, membrane bioreactors are put into large-scale practical applications. According to whether the membrane bioreactor needs oxygen, it can be divided into aerobic and anaerobic membrane bioreactors. Membrane bioreactors are generally used for urban and industrial treatment. Aerobic MBR is used for urban sewage treatment, usually for the purpose of reusing the effluent. Although the MBR process can effectively separate muddy water, it completely intercepts the sludge In the reactor, this will increase the sludge concentration in the reactor, which will lead to aggravated membrane pollution, and excessive flocculent sludge will block the surface pores of the membrane and increase the working pressure of the outlet pump. , until the pumping pressure is too large to work, then the membrane needs to be cleaned, and the cleaning cost of the membrane is quite high no matter whether it is internal cleaning or external cleaning.
