Abstract

The invention belongs to the technical field of waste gas treatment, and particularly relates to a sewer deodorization device. The sewer deodorization device is mounted on a sewer with the upper portion being provide with a manhole cover; a gas outlet is formed in the manhole; the sewer deodorization device comprises a shell used for being placed in the sewer, and an overlapping edge part which extends outwards along the periphery of the top of the shell to be fixedly connected with the manhole cover; the shell is internally provided with an inner cavity used for storing deodorization fillers,and the overlapping edge part extends towards the inner cavity to be provided with an exhaust pipeline communicating with a gas outlet; and the side portion of the shell is further provided with a first vent hole for communicating the sewer with the inner cavity, and the side portion of the exhaust pipeline is provided with a second vent hole communicating the inner cavity with the exhaust pipeline. According to the sewer deodorization device, flammable and explosive gas in stink diffused from the sewer can be effectively removed, thus the hidden danger of the city is eliminated, the concentration of the stink overflowing the bottom face from the sewer is significantly reduced, and the city appearance is improved.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a sewer deodorizing device. Background technique [0002] Urban sewage refers to the general term for sewage discharged into urban sewage systems. In combined drainage systems, it also includes production wastewater and intercepted rainwater. Urban sewage mainly includes domestic sewage and industrial sewage, collected by the urban drainage pipe network and transported to sewage treatment plants for treatment. Malodorous gas refers to the gaseous substance that stimulates the olfactory organs and causes people's unpleasantness and damages the living environment. Malodorous gas not only has a serious impact on the ecological environment, but also has great harm to human health. Chronic diseases, acute diseases, especially malodorous gas substances such as ammonia, hydrogen sulfide, methyl mercaptan, lower fatty acids, and amines produced by the decompositi...
