Environment-friendly sewage treatment equipment based on biological contact

Abstract

The invention relates to the technical field of sewage treatment equipment, and discloses environment-friendly sewage treatment equipment based on biological contact. The equipment comprises a main frame, an aeration device is fixedly mounted at the upper end of the main frame, fixing frames are fixedly mounted at the left end and the right end of the interior of the aeration device, and driving devices are fixedly mounted on the opposite surfaces of the fixing frames; rotating rods are fixedly installed on the opposite faces of the driving devices, and a gas making device is fixedly installedon the rotating rod. According to the environment-friendly sewage treatment equipment based on biological contact, generated oxygen is introduced into the connecting pipe through the fixing frame, the oxygen in the connecting pipe and in the connecting pipe partially comes from the fixing frame, under the action of the gas making device, the oxygen can form airflow in the connecting pipe, and airin the atmospheric environment can be brought into the connecting pipe; therefore, the oxygen amount is increased, the contact effect of wastewater and oxygen is better, and the purpose of better sewage treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a biological contact-based environmental protection sewage treatment equipment. Background technique [0002] Sewage treatment technology can be divided into physical treatment, chemical treatment and biological treatment according to the treatment method. Among them, the most used biological treatment method is the biological contact oxidation device. The biological contact oxidation device includes the tank body, filler, water distribution device and aeration device. Use biofilm to contact with wastewater to achieve the effect of purifying wastewater. [0003] In the traditional biological contact wastewater treatment device, the aeration is generally supplied by blower aeration. During the oxygen supply process, since the oxygen is directly in contact with the wastewater, the contact area is small, and the microorganisms in the sewage cannot be fully contact...
