Rapid oxygenation sewage treatment device

Abstract

The invention discloses a rapid oxygenation sewage treatment device. The rapid oxygenation sewage treatment device comprises a dissolved oxygen chamber and a filter chamber in parallel. The top of thedissolved oxygen chamber is provided with a water inlet. Through a diagonal sliding groove at the top of the dissolved oxygen chamber, large solid wastes in the sewage are effectively intercepted anddischarged timely so that the interception ability of an inclined groove to solid wastes is guaranteed in a continuous treatment process. Through a drum, small waste particles are blocked and the sewage is broken into water drops so that the dissolved oxygen content in the sewage is greatly increased. Through multiple oxygenation processes based on a mixing nozzle and a water falling plate, the organic matters in the sewage can be completely precipitated. A microfiltration membrane can fully intercept the organic matters so that the organic matter content of the sewage reaches to the discharge standard. The activated carbon adsorption network preferentially intercepts the floc formed by the precipitation of the organic matters before the microfiltration membrane intercepts so that the service life of the microfiltration membrane is greatly prolonged and the treatment cost is reduced.

Description

technical field [0001] The invention relates to environmental protection technology, in particular to a rapid oxygenation sewage treatment device. Background technique [0002] In modern life, especially with the deepening of urbanization, the living density of the population is increasing, and the domestic wastewater and some other sewage impurities are also increasing. At the same time, in order to be in the existing living environment More space is found, so urban construction is also increasingly developing towards high-rise buildings and underground buildings, but the problem of urban pollution, especially the problem of domestic sewage, is also becoming more and more serious. [0003] In order to deal with the sewage problem, a lot of sewage treatment equipment have appeared. Before the sewage treatment and discharge, the organic matter content in the water needs to be reduced to avoid the problem of eutrophic water body. The treatment of organic matter in a large amou...

Problems solved by technology

[0003] In order to deal with the sewage problem, a lot of sewage treatment equipment have appeared. Before the sewage treatment and discharge, the organic matter content in the water needs to be reduced to avoid the problem of eutrophic water body. The treatment of organic matter in a large amount of sewage is mainly to increase oxygen. Relying on aerobic reaction to precipitate, filter or absorb organic matter, and at present, the oxygenation of sewage is mainly carried out by aerators, and aerators need to lay a large number of pipelines, and it cannot guarantee that the dissolved oxygen content of sewage at all levels can reach the standard, so directly affect the treatment effect
