Background
The municipal drainage port is a tail end port for conveying and draining water into a water body on the surface of a received ground by a municipal pipeline through a pad surface of a city and is divided into a confluence drainage port and a shunt drainage port. Before entering the surface water body to be received at the tail end of the confluence piping network, a closure facility needs to be adopted, and confluence sewage is held in the confluence pipeline at the upstream side of the closure facility, so that the characteristics of the black and odorous water body can be presented; although the split-system discharge port is located in a pipe network split-system area, due to the complexity of burying a municipal pipe network, even if rain and sewage split is carried out in the split-system area, sewage to a certain degree still exists and is mixed to be connected into the rainwater pipe network, in addition, when the surface water body is treated, the municipal discharge port does not allow sewage to flow into the river in fine days, the tail end of the pipe network is always cut off before the tail end of the pipe network enters the surface water body to be received, so that the mixed-connection sewage is held back in the rainwater pipe in fine days, and the tail end also presents certain black and odorous water body characteristics. The combined exhaust port and the split exhaust port can emit out aerosol carrying harmful virus and germs, and malodorous gases such as ammonia, hydrogen sulfide, mercaptan and the like, which seriously affect the quality of the air environment around the exhaust port and harm the living environment and the health of citizens near the exhaust port.
When the actual operation of municipal pipe network was maintained, in order to avoid municipal drainage mouth aerosol and foul gas's loss, set up the PVC curtain at the row of mouthful end usually and shelter from deodorant, not only deodorant effect is not good, the municipal drainage mouth periphery still has the foul smell peculiar smell, and the PVC curtain still influences row of mouthful view, leads to the citizen often to arrange the mouth to keep away from and keep away from to the municipal administration. A closed treatment device (No. CN111533340B) for virus prevention and control and water purification and deodorization at the discharge port of a pipe network provides a full-section type virus in-situ killing technology for water at the discharge port of the pipe network, but related reports on municipal discharge port aerosol and foul gas are not seen at present. Particularly, the deodorization problem of the aerosol carrying harmful virus and germs at the mouths of large municipal culverts and malodorous gases such as ammonia, hydrogen sulfide, mercaptan and the like, and a disease-preventing bacterium diffusion and deodorization technology is urgently needed. The invention provides a technology for eliminating and killing municipal excretory bacteria and deodorizing malodorous gas, and simultaneously has the effect of beautifying the excretory landscape.

7. A municipal administration exhaust aerosol germ sterilization and malodorous gas collection and removal method is characterized in that: the method comprises the following steps:
1) arranging a curtain type continuous non-breaking water curtain at a municipal discharge port;
2) collecting the gas-water mixed solution after continuous non-broken water curtain washing by using a floating water collecting tank;
3) using strong oxidant to kill virus and germ in gas and water mixed liquor;
4) the gas-water mixed solution after sterilization is sprayed out of the upper layer gas filtering filler tank of the biological filter box through the atomizing nozzle so as to be adsorbed and decomposed by utilizing the synergistic action of microorganisms and plant roots; the water body is filtered and purified by the lower layer water body filtering filler and then is used as a water source of the arc curtain type continuous non-breaking water curtain.
