Problems solved by technology

However, in recent years, the advanced treatment of many difficult industrial wastewater such as landfill leachate, leather wastewater, and coal chemical wastewater has been gradually promoted to the schedule of industrial wastewater treatment. These wastewater not only have high BOD, high ammonia nitrogen, high salinity, but also have certain pH and therefore somewhat corrosive
However, the microporous aerators widely used at present have rubber material on the diffuser surface, and aging and fouling problems will soon occur when used under such wastewater conditions.

Abstract

The invention provides an aerating system, which is used for supplementing oxygen to waste water. The aerating system comprises a jet-flow aerator (4), a circulating pump (2), an air blower (3) and a filter (5), wherein the jet-flow aerator (4) comprises an air inlet (42) and a liquid inlet (43), the air inlet (42) is connected to the air blower (3), the liquid inlet (43) is connected to an outlet of the circulating pump (2), and the filter (5) is connected to the inlet of the circulating pump (2). The aerating system adopting the structure can completely mix an aerating pool.

Description

technical field [0001] The invention relates to an aeration system for aerobic biochemical treatment in the field of sewage treatment. Background technique [0002] In today's increasingly serious environmental pollution, how to control water pollution has become an urgent problem to be solved, especially the treatment of industrial wastewater and domestic sewage, which is mainly carried out by the metabolism of microorganisms, and this process cannot lack the participation of oxygen, so How to efficiently transfer the oxygen in the air to the wastewater, so that it can be effectively used by biology, has become an important topic for many environmental protection companies to study. With the aggravation of water pollution, the problem of eutrophication has become increasingly prominent, among which the excess of ammonia nitrogen and total phosphorus has become a headache for many enterprises. However, whether it is the removal of BOD or the nitrification of ammonia nitroge...
