Quick sewage treatment plant of environmental protection

Technical Field

The utility model relates to a sewage treatment device field specifically is a quick sewage treatment plant of environmental protection.

Background

Aeration refers to the process of forcibly transferring oxygen in the air into the liquid in order to obtain sufficient dissolved oxygen. In addition, the aeration also can prevent the suspension in the tank from sinking and strengthen the contact of the organic matters in the tank with microorganisms and dissolved oxygen. Thereby ensuring the oxidative decomposition of the organic matters in the sewage by the microorganisms in the tank under the condition of sufficient dissolved oxygen.

In the prior art, if the publication number is CN216918745U, a sewage treatment aeration system is specifically disclosed, and specifically, a sealing cover which comprises an aeration tank and is arranged at the opening part at the top of the aeration tank is disclosed, a fixed aeration component is arranged at the bottom in the aeration tank, a rotary aeration component is arranged at the middle part of the aeration tank, one end of the fixed aeration component and one end of the rotary aeration component are connected with an aerator arranged outside the aeration tank, a water inlet pipe is arranged at the top of one end of the aeration tank, and a water outlet pipe is arranged at the bottom of the other end of the aeration tank. Although the introduction of the rotary aeration component can increase the oxygen capacity and simultaneously stir suspended matters in the tank to prevent sedimentation, the device needs to be additionally provided with a driving device for driving the rotary aeration component, so that the manufacturing cost of the device is increased, and the energy consumption in the aeration treatment process is also increased; the factors affecting the oxygen content in the sewage again include various factors, wherein pressure and temperature factors are also important factors, the oxygen content is inversely proportional to the temperature and is positively correlated to the pressure value, so that an aeration device which can reduce the water temperature and the pressure on the surface of the sewage to increase the oxygen content of the sewage, does not affect the temperature required by the active state of most microorganisms (sewage at the middle and lower parts) in the sewage, and can realize sewage treatment by stirring without additionally arranging a power driving unit is needed.
