Description
Technical Field
The utility model relates to the technical field of urban drainage, in particular to a gutter inlet structure with an initial rainwater purification function.
Background
The rainwater inlet is a main way for rainwater to enter an urban rainwater pipe network and is usually arranged at the edge positions of two sides of a road, but at present, the management system of the rainwater inlet in China is not perfect enough, so that the rainwater inlet is frequently subjected to garbage accumulation in cities, and the rainwater inlet is blocked. The rubbish clearance of inlet for stom water and drain pipe is very difficult, the accumulation of silt and rubbish can not be prevented to simple inlet for stom water, because the influence of weather and human factor, the inlet for stom water has more the leaf, rubbish such as plastic bag is piled up, cause the inlet for stom water to block up easily, and simultaneously, the rainwater flow can bring partial silt and rubbish into inside the pipeline, form the siltation of intraductal silt and rubbish, seriously probably block the pipeline even, come interim when heavy rain, in case rubbish has blockked up partial inlet for stom water and drain pipe, will cause the reduction of water cross section, the drainage flood discharge function will receive serious influence, road ponding is in the unavoidable, influence normal traffic.
The initial rain is the rainfall forming surface runoff in the early stage of rainfall. In the early stage of rainfall, a large amount of polluting gases in the atmosphere are dissolved by rainwater, and after the rainwater falls to the ground, roof, roads and the like are washed away, so that the initial rainwater contains a large amount of pollutants, and the pollution degree of some initial rainwater is higher and even exceeds urban domestic sewage. If the rainwater is directly discharged, the pollution of the receiving water body is inevitably intensified. The traditional gutter inlet is single in function, focuses on improving the drainage capacity of the gutter inlet, and does not have the capacity of peak clipping and dirt blocking.
Some of the prior art rainwater well patents with filtering function, such as the rainwater well garbage collecting box, the rainwater well garbage collecting device and the rainwater well system patent disclosed in CN201520233608.9, realize the filtering treatment of garbage by adding a garbage collecting box in the rainwater well. For another example, in a rainwater well filtering device and a rainwater well patent disclosed in cn201920353751.x, garbage is filtered by adding a filtering tank in a rainwater well. However, these prior arts can only realize simple filtration of garbage, can remove floaters with large volume, but cannot treat pollutants in rainwater, especially pollutants in initial rainwater.
The applicant has applied for patent CN202021069582.6 and has disclosed a garbage-retaining basket, a rainwater treatment device and a rainwater inlet structure, in which the garbage-retaining basket is adopted to retain the floating objects in the rainwater, and the filtering layer is adopted to filter the pollutants in the rainwater. However, when the rainwater is excessively large, the pollutant components accumulated in the filter layer are still discharged to the sewage through the overflow pipe, and the pollutant treating effect is lost.
Therefore, in order to control the problem of initial rain runoff pollution from the source and make up the defects of the traditional rainwater inlet, the technical personnel in the field need to consider and design a rainwater well structure which can better realize the purification treatment of initial rainwater pollutants and improve the rainwater pollution treatment effect.

Furthermore, a layer of non-woven fabric is laid on the inner side of the second accommodating body.
Therefore, the initial rainwater filtering effect can be further improved, and meanwhile, the peripheral soil body is prevented from entering the second accommodating body.
Further, rain is combed the peripheral lid and is equipped with round curb, and rain is combed the upper surface and is less than the curb, and curb upper surface and ground flush, evenly laid all around the curb and crossed the water hole, crossed water hole lower extreme level inwards and rain is combed the upper surface intercommunication.
Like this, the water hole of crossing can play the effect of reposition of redundant personnel energy dissipation to the rainwater, slows down the rainwater velocity of flow, avoids the rainwater velocity of flow to overflow the initial stage rainwater at the excessive speed and holds back the treatment zone and directly enter into the outlet, can reduce the washing away of rainfall runoff to filtering material simultaneously, guarantees the filter effect.
The utility model is based on the theory of sponge city construction, can realize the storage and purification of initial rainwater, and greatly reduces pollutants carried by initial rainwater runoff. The initial rainwater is purified by the rainwater inlet and then directly seeps into the rainwater inlet, so that underground water resources can be supplemented. The filter material adopted in the gutter inlet device has a large specific surface area, and can provide a good growth environment for the growth of various microorganisms, so that various pollutants such as organic matters, oils, heavy metals and the like can be removed. The device reasonable in design, the filter bed is as removable part, and the maintenance management of being convenient for does benefit to cyclic utilization, and the design of the mode of intaking is applicable to the mountain region city, plays the energy dissipation effect, reduces the washing away to the filler.
In conclusion, the utility model can realize the interception and purification treatment of initial rainwater and improve the treatment effect of rainwater pollution; have storage and purification ability concurrently, from the source control initial stage rainwater runoff's pollution, realize low influence development, the effect of protection water environment.
