High-efficiency wastewater aeration system for water supply and drainage and aeration process

Abstract

The invention belongs to the field of wastewater treatment, in particular to a high-efficiency wastewater aeration system for water supply and drainage. According to the scheme, the high-efficiency wastewater aeration system comprises an aeration barrel and a water storage tank, a rotating table is fixedly connected to the bottom of the aeration barrel, and a driving assembly for driving the aeration barrel to rotate is arranged at the bottom of the aeration barrel. The high-efficiency wastewater aeration system is simple in structure and convenient to operate. A first rotating motor is started to drive the aeration barrel to start to rotate, so that aeration rods and an activated carbon placement frame can stir wastewater in the aeration barrel, and oxygen is injected into the wastewaterin the aeration barrel through an aeration circular pipe and the aeration rods while stirring, so that the oxygen can be fully mixed with the wastewater. In addition, when the activated carbon placement frame stirs, activated carbon in the activated carbon placement frame can filter and remove impurities in the wastewater in the aeration barrel. By rotating a second nut, braking of the activated carbon placement frame by the second nut can be relieved, so that the activated carbon in the activated carbon placement frame is conveniently replaced, and activated carbon failure is prevented.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a high-efficiency wastewater aeration system for water supply and drainage and an aeration process. Background technique [0002] Drainage science and engineering, referred to as water supply and drainage, generally refers to urban water supply systems and drainage systems (municipal water supply and drainage and building water supply and drainage). In the drainage system, the treatment of wastewater is an important project, and the removal of organic matter in wastewater is often achieved by biological contact oxidation. The biological contact oxidation method is a biofilm treatment process between the activated sludge method and the biological filter tank. It is characterized by setting fillers in the tank, aeration at the bottom of the tank to oxygenate the sewage, and making the water in the tank flow state to ensure that the sewage is fully in contact with the ...

AI Technical Summary

Problems solved by technology

[0004] There are still the following disadvantages in the above technical solution: 1. The oxygen enters the aeration tank from a nozzle, and the oxygen supply is unevenly distributed, which is not conducive to the uniform mixing of oxygen and water body and the oxygen supply is insufficient; 2. Activated carbon is placed in the aeration tank It is used to filter wastewater, but the activated carbon cannot be replaced, resulting in the inability to filter wastewater again after long-term use; 3. The timing of drainage and water intake is fixed, and it cannot be controlled according to the actual situation of wastewater aeration. When the gas is not completed, the water will start to enter and exit, which will affect the follow-up work
