Description

Aeration device for hospital sewage treatment Technical Field The utility model belongs to the technical field of sewage treatment, and relates to an aeration device for hospital sewage treatment. Background In the course of working and living, hospitals can produce a large amount of medical wastewater and domestic sewage. When sewage is discharged, the sewage needs to be treated. Aeration treatment is an important process in sewage treatment, and aeration is to increase the contact between sewage and oxygen by bubbling air or oxygen into the sewage, so that the microorganisms in a pool can be guaranteed to carry out oxidative decomposition on organic matters in the sewage under the condition of sufficient dissolved oxygen. In order to improve the contact between oxygen and water, a microporous device is usually arranged at the bottom of the water body and is communicated with an air pump so that gas is diffused through micropores. However, because of the large amount of solid particles in the sewage, the position where the aeration device releases oxygen may be blocked during long-term use. Disclosure of utility model Aiming at the problems, the utility model provides an aeration device for hospital sewage treatment, which well solves the problems in the prior art. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: An aeration device for hospital sewage treatment, comprising: The two ends of the water containing tank are provided with a water inlet and a water outlet; The diffuser is provided with a plurality of micropores at the upper end and an air inlet pipe; the valve cores are arranged on the micropores in a one-to-one correspondence manner; The output end of the air pump is connected with the air inlet end of the diffuser; The output end of the circulating pump is fixedly arranged at the upper end of the water containing tank, and the input end of the circulating pump is fixedly connected to the bottom of the water containing tank. Optionally, the diffuser comprises: The valve core and the air inlet pipe are arranged on the sinking part; The floating part is fixedly arranged on the sinking part and is an air bag; the input end of the pressure release valve is connected with the air inlet pipe, and the output end of the pressure release valve is connected with the floating part; and the exhaust valve is fixedly arranged on the floating part. Optionally, the air inlet pipe is a hose. Optionally, the valve core is threadably connected to the micro-bore.
