Assembled rainwater purification device

Technical Field

The utility model relates to the technical field of rainwater purification, in particular to an assembled rainwater purification device.

Background

Most of the existing rainwater drainage systems flow into a drainage pipeline through a sewage interception well arranged on the ground and are discharged into a downstream water body. Along with the increase of urban pollution and human activity pollution, the water pollution of rainwater before flowing into a water collecting well is serious. The rainwater contains a great amount of pollutants such as grease, suspended solids, sediment and the like. Therefore, the pollution degree of the rainwater is higher, and if the rainwater is directly discharged into the downstream water body, serious pollution is caused to the water body.

At present, the rainwater is treated by adopting a mode of collecting and blocking and filtering for many times, for example, chinese patent No. 113931253A discloses a method for comprehensively recycling rainwater and sewage, which comprises the steps of firstly enabling surface rainwater to flow into a well through a collecting port, an external pipeline and the like, and adding a grid at the inlet to block large pollutants outside a pipe network system; then small pollutants, sediment and the like can enter a pipe network system, and the pollutants which cannot be removed by the grid in the rainwater are further treated by additionally building a regulating reservoir or a drainage well and the like, so that the pollution degree of the initial rainwater is reduced to the minimum as much as possible.

However, as urban inland inundation and rainfall flood pollution become serious, the traditional initial rainwater pollution treatment device and method fall behind and have poor effect, so that the pressure of rainwater and municipal pipe network is high, and the sewage plant and the river channel are also burdened. In addition, the traditional treatment device has large occupied area and low pollutant interception efficiency; the construction is complex and the period is long; the later cleaning and maintenance are complicated, and the current requirements are difficult to meet.
