Buried green belt sewage collection and treatment device

Abstract

The invention discloses a buried green belt sewage collection and treatment device, and relates to a sewage collection and treatment device. The purpose is to solve the problem that drainage of road rainwater easily causes river pollution in cities. The device consists of an isolation water collection device and a treatment device, the upper end of the isolation water collection device is open, and the isolation water collection device is internally provided with a plurality of isolation nets horizontally arranged from top to bottom; and a housing of the treatment device is internally provided with a precipitate separator, a porous filter layer, an upper treatment area and a precipitate collection tank. According to the invention, silt, chemical pollutants and the like in rainwater are purified, so that the pollution of rainwater to rivers is reduced, and the ecological environment of river water is protected; the device is a buried green belt sewage collecting and precipitating device, is not influenced by space, and does not occupy land; the device does not affect ecological environment construction, reduces the river treatment cost, and is convenient to operate. The device is suitable for treating river pollution in cities.

Description

technical field [0001] The invention relates to a sewage collection and treatment device. Background technique [0002] With the continuous development of cities, people's lives are getting closer to nature. Roads, bridges, and even high-rise buildings have been built around urban rivers and lakes. Also, with the increasing number of surrounding living population, some pollution is caused to the rivers in the city, and the rainwater from the roads next to the rivers and lakes is also directly discharged into the rivers. The rainwater is not collected, treated and utilized, and it is directly discharged into the river, mixed with soil and other sundries on the ground, which will make the river turbid, resulting in low visibility of the river water, and the long-term inflow of sediment will lead to the accumulation of sediment at the bottom of the river. Accumulative anaerobic effects affect water quality, river pollution reaches a certain level, and sediment dredging is requ...
