Initial rainwater diversion method
The invention discloses an initial rainwater diversion method. Rainwater in a water collection area flows into an initial rainwater diversion device through a plant area rainwater gutter, rainwater infirst 15 minutes flows into a initial rainwater collection pool through an initial rainwater gutter, the highest water level of the initial rainwater collection pool is flush with the top of the initial rainwater gutter, the effective volume below the highest water level in the pool equals to the rainwater amount for the first 15 minutes in the water collection area, and after the water level ishigher than the highest water level, due to the fact that the top of the initial rainwater gutter is flush with the bottom of the later rainwater gutter, later rainwater flows away from a later rainwater gutter through the initial rainwater diversion device and enters a plant area water pond after large impurities are filtered through a grid so as to realize diversion. Rainwater zero emission is realized, the environment pollution caused by the fact that initial rainwater is directly discharged outside without treatment is avoided, initial rainwater is treated by fully utilizing a leachate treatment station matched with a garbage power generation project or a waste water treatment station arranged by other items, the rainwater is recycled after reaching the standard, the later rainwater with a low pollutant concentration is fully recovered, and a water resource is effectively saved.
本发明公开了一种初期雨水分流方法，汇水面积内的雨水经过厂区雨水沟流入初期雨水分流装置，前15分钟的雨水经过初期雨水沟流入初期雨水收集池，初期雨水收集池的最高水位与初期雨水沟顶部齐平，池内最高水位以下有效容积为汇水面积内的前15分钟雨水量，水位高于最高水位后，由于初期雨水沟顶部和后期雨水沟底部齐平，后期雨水会通过初期雨水分流装置从后期雨水沟流走，并经过格栅过滤较大的杂质后进入厂区水塘，从而实现分流。实现雨水零排放，避免初期雨水不经处理直接外排对环境的污染，充分利用垃圾发电项目配套的渗滤液处理站或其他项目设置的废水处理站处理初期雨水，达标后回用；充分回收污染物浓度较低的后期雨水，有效节约了水资源。
