With the continuous improvement of people's living standards and living environment requirements, the deodorization of various sewage stations has been widely valued. Environmental quality standards are increasingly strict, and the promotion and research and development of deodorization technology in sewage stations should be accelerated. Any gas substance that can stimulate the olfactory organs, thus causing unpleasantness and destroying the living environment can become a malodorous gas. Odor gas pollution has become one of the seven major environmental hazards in the world, so all countries attach great importance to the prevention and control of odor gas pollution.

Source and harm of odor in sewage treatment station

Odor source of sewage treatment station The main structures that produce odor in sewage treatment station are: water inlet, sedimentation tank, grit chamber, oil separation tank, air flotation tank, biological reaction tank, sludge tank and sludge dewatering room. Due to the different processes used in sewage treatment stations, the concentration of malodorous pollutants produced is also very different. Generally speaking, the concentration of malodorous pollutants produced by biochemical treatment is higher, followed by physicochemical treatment.
