Domestic sewage purification device for high-rise building in city

Abstract

The invention discloses a domestic sewage purification device for a high-rise building in a city and belongs to the field of sewage purification for the high-rise buildings. The domestic sewage purification device for the high-rise building in the city comprises a flushing filtering pipe, wherein the flushing filtering pipe fixedly sleeves a sewage discharging bottom pipe for the high-rise building through a connecting sleeve. The device can be connected with a water outlet end of the sewage discharging bottom pipe for the high-rise building on a bottom layer of the high-rise building; a multileveled filtering layer in the flushing filtering pipe is used for carrying out multileveled purification treatment on sewage discharged by the sewage discharging bottom pipe for the high-rise building and a purification effect is good; meanwhile, the multileveled filtering layer can rotate under the driving of a solenoid valve; when the device is used for carrying out filtering treatment, the filtering layer is horizontally arranged and is used for filtering; after the device is used for filtering for a period of time, the solenoid valve drives the filtering layer to overturn for 300 to 340 degrees; pure water is flushed through a flushing pure water pipe and is used for carrying out back-flushing on a back surface, so that the filtering effect of the flushing filtering pipe is ensured; sewage treatment is directly carried out on the bottom of a floor, the cost is relatively low and the consumption of energy sources is small.

Description

technical field [0001] The invention relates to the field of high-rise sewage purification, and more specifically relates to a domestic sewage purification device for high-rise buildings in the city. Background technique [0002] With the development of social economy, the number of high-rise buildings in modern society is increasing, and the height is getting higher and higher. Most of the high-rise buildings are built in prosperous areas, and the waste water used in high-rise buildings is mostly discharged through sewage discharge pipes. side, and then use the transfer pump to transport the sewage to the sewage treatment plant. Since the high-rise building is far away from the sewage treatment plant, and the high-rise building is located in a prosperous area, the cost of sewage transport to the treatment plant is high and consumes a lot of energy.
