Abstract

The invention relates to the technical field of sewage treatment, and in particular relates to a sewage filtering device. The sewage filtering device comprises a water inlet, a primary filtration pipe, a refined filtration pipe and a water outlet pipe which are sequentially arranged from top to bottom, wherein a deslagging pipe is arranged on the side wall of the primary filtration pipe, a filter screen is arranged in the primary filtration pipe, one end, far away from the deslagging pipe, of the filter screen is hinged with the inner wall of the primary filtration pipe; and a cobblestone layer, a quartz sand layer, a magnetite filtering material layer and an activated carbon layer are sequentially arranged in the refined filtration pipe from top to bottom. The sewage filtering device provided by the invention has the advantages that sewage with higher solid content can be rapidly and stably treated, impurities in the sewage are removed by virtue of the filter screen, then the sewage is further filtered by virtue of the refined filtration pipe, and granule impurities in the sewage are removed; then the sewage is subjected to disinfection treatment by virtue of an ultraviolet lamp irradiation tube in a diversion tube and is then discharged from the water outlet pipe after the disinfection treatment is finished, so that filtration of solid impurities in the sewage is realized; and meanwhile, the device provided by the invention has high filtering efficiency, good filtering effect and significance on promotion of the development of sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage filtering device. Background technique [0002] my country is a country that lacks water resources. With the development of the economy and the improvement of people's living standards, the consumption of fresh water resources and the corresponding discharge of domestic sewage and industrial wastewater continue to increase. Due to backward economic and technical conditions, pollution has not been achieved. Timely control, nationwide water pollution is becoming increasingly serious. The direct discharge of a large amount of sewage without effective treatment has caused a series of environmental problems such as river pollution and eutrophication of lake water, which has seriously deteriorated the ecological environment of my country's surface water bodies. Serious water pollution and shortage of water resources have become prominent problems that restrict my coun...
