Description

Green roof rainwater is collected and cyclic utilization system based on tradition sponge wisdom

Technical Field

The utility model relates to a water circulating system technical field, concretely relates to green roof rainwater is collected and cyclic utilization system based on traditional sponge wisdom.

Background

In recent years, waterlogging becomes an urgent problem to be solved in many cities when raining. At present, many cities adopt a fast drainage mode, rainwater can only be concentrated and quickly drained from a pipeline after falling to a hardened ground, 70% of rainwater in the cities is lost in the mode, and if most of rainwater is left instead of being drained, the rainwater can be stored, permeated and purified in urban areas to the maximum extent, so that the utilization of rainwater resources and the ecological environment protection are promoted. That is to say, sponge city construction is expected to be absorbed, stored, permeated and other links before discharging a large amount of water to the tail end of the pipe canal, and becomes an effective way for breaking the rain and waterlogging instead of relying on the enlarged drain pipe.

The international common language of sponge cities is "low impact development rainwater system construction", i.e. absorbing, storing, percolating, purifying water in the rain, releasing and utilizing the stored water when needed. The sponge city can maximally realize the storage, permeation and purification of rainwater in the urban area on the premise of ensuring the safety of urban drainage and waterlogging prevention, and promotes the utilization of rainwater resources and the ecological environment protection. Such as rivers, lakes, ponds and other water systems, and greenbelts, gardens, permeable pavements and other city supporting facilities. Rainwater seeps, is stored, purified and recycled through the sponges, and finally the rest part is discharged outside through a pipe network and a pump station, so that the standard of an urban drainage system is effectively improved, and the urban waterlogging pressure of a changed part is effectively improved.

On the one hand, however, with the development of cities, non-permeable ground in urban areas such as: cement ground, granite ground etc. are bigger and bigger, and the infiltration ability of rainwater reduces by a wide margin, causes the continuous increase of rainfall ground runoff, and urban drainage system receives very big examination, causes very big threat for the normal production life in city. Meanwhile, as the rainwater infiltration capacity is reduced, the groundwater cannot be well supplemented, and the reduction of the groundwater level not only influences the growth environment of ground vegetation, but also causes serious geological disasters.

At present, most of China still faces a serious situation of water resource shortage. The rainwater is a precious fresh water resource, is slightly polluted, and can be used as a miscellaneous water source for greening, car washing and the like after being simply treated. Under the situation that water resource shortage is more and more serious, rainwater is collected and utilized more and more importantly, new water sources can be opened up, urban water resources are saved, the runoff of rainwater ground can be reduced, the danger of occurrence of rain flood disasters is reduced, and remarkable economic benefits, social benefits and environmental benefits are obtained.
