技术领域technical field
本发明涉及一种雨水处理装置，具体是一种初期雨水弃流装置。The invention relates to a rainwater treatment device, in particular to an initial rainwater abandonment device.
背景技术Background technique
随着我国城市化快速发展，导致用水量的陡增，水资源短缺现象日益严峻，为了可继续城市发展的需要，雨水资源的再利用得到了广泛重视。With the rapid development of urbanization in my country, the water consumption has increased sharply, and the shortage of water resources has become increasingly serious. In order to meet the needs of sustainable urban development, the reuse of rainwater resources has been widely valued.
初期雨水，即降雨初期的雨水。一般是指地面10-15mm厚已形成地表径流的降水。由于降雨初期，雨水溶解了空气中的大量酸性气体、汽车尾气、工业废气、PM2.5等污染性气体和污染物，降落地面后，又由于冲刷屋面、沥青混凝土道路等，使得前期雨水中含有大量的污染物质，因此，初期雨水中含有大量的污染物质，污染程度较高，甚至超出普通城市污水的污染程度。未经处理的初期雨水直接排入雨水管网或者河道，给水环境造成了一定程度的污染的同时，会对后续的雨水处理造成较大压力，影响雨水的再利用。Initial rainwater, that is, rainwater at the beginning of rainfall. Generally, it refers to the precipitation that has formed surface runoff with a thickness of 10-15mm on the ground. In the early stage of rainfall, the rainwater dissolved a large amount of polluting gases and pollutants in the air, such as acid gas, automobile exhaust, industrial waste gas, PM2.5, etc. Therefore, the initial rainwater contains a large amount of pollutants, and the pollution level is relatively high, even exceeding the pollution level of ordinary urban sewage. The untreated initial rainwater is directly discharged into the rainwater pipe network or river course, which causes a certain degree of pollution to the water environment and at the same time puts a lot of pressure on the subsequent rainwater treatment and affects the reuse of rainwater.

上述初期雨水弃流装置安装后，下雨天，城市建筑设施的排水系统收集的初期雨水经进水口15引入该弃流装置，首先由导流腔11内安装的提篮格栅3进行初步过滤，过滤拦截树叶等较大的垃圾，过滤产生的垃圾被收集在提篮格栅3内，便于定期清除；过滤后的污染较大的初期雨水经集水器2进入弃流腔12，再经弃流口17排入城市污水管网；随着下雨时间的延长，雨量越来越大，弃流腔12内迅速填满雨水，导致下浮球42上浮并封住集水器2的下口，这时经进水口15进入导流腔11的雨水经提篮格栅3过滤后直接从出水口16排入城市雨水管网。随着雨量的减小或雨停，少量的雨水会渗漏到弃流腔12内，但不会造成有害影响。After the above-mentioned initial rainwater abandonment device is installed, on rainy days, the initial rainwater collected by the drainage system of urban building facilities is introduced into the abandonment device through the water inlet 15, and the basket grid 3 installed in the diversion cavity 11 is initially filtered. Larger garbage such as leaves is intercepted, and the garbage produced by filtration is collected in the basket grille 3, which is convenient for regular removal; the filtered initial rainwater with relatively large pollution enters the waste flow chamber 12 through the water collector 2, and then passes through the waste flow port 17 is discharged into the urban sewage pipe network; with the prolongation of the raining time, the rainfall is getting bigger and bigger, and the rainwater is quickly filled in the waste flow chamber 12, causing the lower floating ball 42 to float up and seal the lower mouth of the water collector 2. At this time The rainwater entering the diversion cavity 11 through the water inlet 15 is directly discharged into the urban rainwater pipe network from the water outlet 16 after being filtered by the basket grille 3 . As the rainfall decreases or the rain stops, a small amount of rainwater will seep into the flow-discarding cavity 12, but it will not cause harmful effects.
