[0002] A large amount of domestic wastewater and industrial wastewater are produced in daily life and industrial production. In order to avoid environmental pollution caused by direct discharge of wastewater, domestic wastewater and industrial wastewater are usually collected and treated in a centralized manner. After the wastewater is collected, a large amount of waste gas will be generated. The spread of the foul smell in the waste gas in the atmosphere will cause serious air pollution, which is not in line with the environmental protection concept of wastewater treatment. Therefore, it is necessary to collect the waste gas and filter it to remove the bad smell. However, the biological filler used in the centralized waste gas treatment device of the existing waste water station Due to insufficient oxygen content and nutrient solution, the organic nutrient and activity of the biofiller are low, which affects its absorption of exhaust gas odor and microbial oxidative decomposition and deodorization performance

The invention discloses a biological filtration device for centralized treatment of waste gas in a wastewater station. The biological filtration device comprises a wastewater collecting tank, a gas collecting cover, a constant-temperature humidifying pipe and a biological filtration tower, wherein the gas collecting cover is mounted at the top of the wastewater collecting tank, the constant-temperature humidifying pipe is mounted at the top of the gas collecting cover, an axial flow fan is fixedly mounted between the gas collecting cover and the constant-temperature humidifying pipe, the biological filtration tower is mounted at the top of the constant-temperature humidifying pipe, a purified gas outlet and an odorous waste gas inlet are formed in the top and bottom of the biological filtration tower, and a biological filtration filler layer is mounted in the biological filtration tower. Aeration of biological filtration filler and addition of a nutrient solution are performed by the aid of an aeration pipe and an aerator, so that organisms can have sufficient organic nutrients and keep higher activity, absorption of waste gas odors by the biological filtration filler and microorganism oxygenolysis deodorization can be effectively improved, purification and up-to-standard emission of waste gas in wastewater are realized, the atmospheric pollution is reduced, and the environmental protection performance of wastewater treatment is improved.
