饮用水源地保护区内路面初期雨水的水处理工艺

Water Treatment Technology of Highway Initial Rainwater in Drinking Water Source Protection Areas

为缓解饮用水源地保护区内公路运营引发的水污染问题,应对初期雨水及事故废水进行收集并处理.以某公路建设工程为依托,探讨了初期雨水和事故废水的水处理工艺.采用沉淀池与人工潜流湿地组合式处理初期雨水,自动智能连通事故应急池处理事故废水.计算确定水处理工艺各单元的容积.出水水质分析表明,该工艺可以满足杂用要求.

In order to relieve the water pollution problem of highway project in the source of drinking water protection area,the initial rainwater and wastewater should be collected and treated.Taking a highway construction as example,the water treatment technology of initial rainwater and wastewater of accident are discussed.It is proposed that,the initial rainwater could be treated by settling tank and constructed subsurface flow wetland,and the wastewater of accident could be treated by automatically connecting with the accident emergency pool.The volume of water treatment units are calculated and determined. According to effluent quality analysis,this technology can meet miscellaneous requirements.
