01. directly discharged into a river channel without treatment, and rainwater at the early stage of rainfall is dirty, so that water body pollution is caused;
02. the rain sewage and the sewage are converged together and enter a sewage plant, and are discharged after being treated, if the treatment capacity of the sewage plant is designed according to the sewage flow, the flow in rainy days is suddenly increased, the water quality is changed violently, the activated sludge of the sewage plant is easy to lose, and the reduction of pollutants cannot be realized;
03. rain sewage flows together to enter a sewage plant, is discharged after treatment, and if the treatment capacity of the sewage plant is designed according to the flow of the flow, a large amount of equipment is left unused for a long time and a large amount of cost is brought by the long-term maintenance of an idle biochemical pool.
Therefore, with the increasing awareness of environmental protection and the increasing economic strength, and with the recent emergence of problems such as blacking and odorization of urban rivers, the drainage mode of the rain sewage flow is gaining acceptance.
