背景技术Background technique
常规雨水利用技术一般都是具有单一功能,如雨水收集、雨水净化等功能,没有很好的衔接好各综合功能,不能充分的利用好雨水资源;天然雨水往往大量携带地面上的大量生活垃圾与污染物,未经净化后雨水排放到自然环境中,会加剧自然水体的污染程度;遇到暴雨时,会造成城市地表径流量大幅提高,市政管网泄洪能力远远不足,引发道路洪涝积水;常规雨水净化系统往往没有从收集雨水时就考虑净化过程,造成净化成本较高,净化效率低。Conventional rainwater utilization technology generally has a single function, such as rainwater collection, rainwater purification and other functions, without a good connection between various comprehensive functions, and cannot make full use of rainwater resources; natural rainwater often carries a large amount of domestic garbage and water on the ground. Pollutants, unpurified rainwater discharged into the natural environment will aggravate the pollution of natural water bodies; in the event of heavy rain, it will cause a substantial increase in urban surface runoff, and the flood discharge capacity of the municipal pipe network is far from sufficient, causing road flooding and waterlogging ; Conventional rainwater purification systems often do not consider the purification process from the time of collecting rainwater, resulting in high purification costs and low purification efficiency.
现有的蓄水系统没有将环保、城市绿化、景观打造等技术融合在一起,仅在雨天将雨水进行收集蓄水,在旱天排出利用,虽然在一定程度上能够缓解城市雨水带来的洪涝压力,但是没有充分的对雨水进行处理并循环利用,雨水资源没有充分利用到绿色城市建设中。The existing water storage system does not integrate technologies such as environmental protection, urban greening, and landscape construction. It only collects and stores rainwater in rainy days and discharges it for use in dry days. Although it can alleviate urban floods caused by rainwater to a certain extent However, the rainwater has not been fully treated and recycled, and the rainwater resources have not been fully utilized in the construction of green cities.
