[0002] In the system of oxygen type ozone generator for removing COD in water by ozone, in addition to the application of ozone as hydroxyl radical, oxygen is contained in the tail gas, which is a good collocation when the back end is connected with a biochemical system, and the oxygen provides the demand of bacteria for dissolved oxygen, but in the zero discharge system, when the back end is connected with a large capacity water tank and a membrane system, it often becomes a burden, therefore, the deoxygenation membrane is connected behind the ozone reaction tank to reduce the oxygen in water to a certain concentration, and the mixed gas containing nitrogen and oxygen can be returned to the front end after dehumidification and used as an oxygen source. The deoxygenation membrane assembly comprises a solution flow pipe, a deoxygenation membrane body and a deoxygenation cavity, a vacuum pump can perform vacuumization in the deoxygenation cavity, oxygen in the solution on the inner side of the deoxygenation membrane is sucked out and passes through the deoxygenation membrane body and is then collected by the vacuum pump, when the deaeration efficiency of the deoxygenation membrane is reduced and cannot meet the production demand, such as when the oxygen concentration of the effluent cannot reach the expected low level, the deoxygenation membrane should be replaced. However, in the process of replacing the deoxygenation membrane of the existing deoxygenation membrane assembly, the deoxygenation membrane assembly needs to be completely removed from the installation place and then disassembled to replace the deoxygenation membrane.

It should be understood that by arranging the boss, when the liquid flows to the drainage cover, the space between the drainage cover and the annular filter membrane body gradually decreases, and the water flow speed may increase due to the decrease in the space volume. According to Bernoulli's effect, the increase in flow speed leads to a decrease in pressure, which helps the gas dissolved in the water to overflow, thereby facilitating deoxidation.
