Device and method for sterilizing aerosol germs and collecting and removing malodorous gas at municipal discharge port

Abstract

The invention discloses a device and a method for sterilizing aerosol germs and collecting and removing malodorous gas at a municipal discharge port. The device at least comprises an upper water curtain covering unit and a lower water collecting unit, the upper water curtain covering unit comprises a horizontal sealing cover plate fixed at the upper edge of the river inlet of the municipal discharge port; an arc-shaped water distribution pipe is arranged around the peripheral side of the horizontal sealing cover plate; the arc-shaped water distribution pipes discharge water downwards to form a curtain type continuous non-breaking water curtain; the lower water collecting unit comprises a floating body type water collecting tank; the floating body type water collecting tank floats up and down along with the water level at the joint of the municipal discharge port and the river; mixed liquid leached by the arc-shaped curtain type continuous non-breaking water curtain enters the floating body type water collecting tank; and a water pump is arranged in the water collecting tank. The method is suitable for killing aerosol germs and eliminating stink at the discharge port of the large municipal box culvert, does not affect normal drainage of the municipal discharge port, and also has the effect of beautifying the municipal discharge port.

Description

technical field [0001] The invention relates to a device and method for disinfecting aerosol germs and collecting and removing malodorous gas at municipal exhaust outlets. Background technique [0002] The municipal outfall is the end port where the urban runoff from the underlying surface is transported through the municipal pipeline to the receiving surface water body. It is divided into a confluence system and a diversion system. Interception facilities are required at the end of the combined pipe network before it enters the receiving surface water body. On the upstream side of the interception facility, the combined sewage is "suffocated" in the combined pipe, which will present the characteristics of black and odorous water; although the outlet of the diversion system is located in the pipe network In the diversion system area, due to the complexity of the buried municipal pipe network, even if the rain and sewage diversion is carried out in the diversion system area, ...

AI Technical Summary

Problems solved by technology

[0003] In the actual operation and maintenance of the municipal pipe network, in order to avoid the escape of aerosol and malodorous gas at the municipal discharge outlet, PVC curtains are usually installed at the end of the discharge outlet to block and deodorize. The curtain also affects the view of the outlet, causing citizens to avoid the municipal outlet

A closed treatment device for virus prevention and control and water purification and deodorization at pipe network outlets (authorized announcement number CN111533340B) provides a full-section virus in-situ elimination technology for pipe network outlet water bodies, but So far, there have been no relevant reports on aerosols and odorous gases from municipal exhaust outlets
