Description
Technical Field
The utility model relates to a device for intercepting and purifying initial rainwater at a river mouth in an industrial living combined pollution area, and belongs to the field of water environment research.
Background
At present, many industrial village and town sewage collecting and treating systems in China are not complete enough, and particularly, a treatment system aiming at rain and sewage converging is more difficult to see, and many industrial sewage is mixed with initial rainwater to directly enter a river channel through a river inlet, so that the pollution degree of the river channel is increased. It is known that the initial rainwater dissolves a large amount of acidic gases, automobile exhaust, factory exhaust and other polluting gases in the air, and after falling to the ground surface, a large amount of pollutants mixed with roof and road flushing enter a sewer, and are directly discharged into a river through the sewer. In large cities of China, initial rainwater and other wastewater are treated separately, and the rainwater is treated and discharged separately, so that the burden of a sewage treatment plant is relieved, but because the rainwater and sewage diversion is a small project, the village and town area is small, the rainwater is not just in parallel with the industrial wastewater and is converged into a river channel, the requirements of rainwater and sewage diversion can not be met in many small industrial villages and towns at present, the water entering the river channel is a rainwater and sewage river, and a large amount of pollutants in the initial rainwater greatly aggravate the pollution degree of discharged water. Especially when facing a great deal of rainfall in a transient state, a great deal of surface runoff formed by the initial rainwater is mixed with pollutants and rapidly enters a river channel through a drain pipe. How to cope with the initial rainwater discharge is an unprecedented problem. The presently disclosed patents, such as China patent utility model, grant publication number: CN 206566598U, publication date: the device can meet the requirements of treating solid particles, partial suspended matters and organic matters, but the device firstly occupies a large area, secondly is buried underground, and in order to prevent soil scouring from affecting the device, the stability of a foundation and the pouring of concrete are necessarily required, so that the engineering quantity is large, and the overall flexibility is small. Similar to such initial rainwater treatment apparatuses requiring excavation and burying, the flexibility of the apparatus is too small, and for example, patents (grant bulletin number: CN 106894466A, publication date: 2017, month 06, and 27), patents (grant bulletin number: CN 206570904U, publication date: 2017, month 10, and 20) have limitations of such flexibility. In addition, chinese patent utility model, grant bulletin number: CN 106939635A, publication date: the first filtering and storing device for rainwater on overhead roads is disclosed in 2017, 07 and 11, and can be used for treating solid particles, suspended matters and grease and storing the rainwater, but can only be used for treating the rainwater, and cannot remove nutrient salts such as nitrogen, phosphorus and the like.
