对前有综合池的污水湿地处理规模的研究

对于前有综合池的雨污合流市政雨水管道水体的湿地处理措施的适宜规模,采用在潜流湿地中埋设土壤溶液采集器的陶瓷头,在不同位置取水监测的方法来探讨。从土壤溶液采集器的取水结果来看,若忽略陶瓷头对SS的过滤作用及SS与其他污染物的相关性带来的对其他污染物的过滤作用,除个别情况外,几乎所有位置的污染物出水浓度均能达到北京市地方标准DB11/307-2005水污染物排放标准中的一级B限值要求。因此,可以初步确定,若以DB11/307-2005水污染物排放标准中的一级B限值要求为出水目标,上述水质水量的来水对应的试验所设计的潜流湿地的处理规模为:长度方向为距离进水口10m,深度方向为距离上表面20cm。湿地的设计面积以及填料深度的最终确定有待进一步研究。

Initial Discuss of the Scale of Wetland Treatment

For the suit scale of the wetland which with comprehensive pool in front of it to treat water come from municipal rainwater and sewage water pipes,adopt the methods of inspecting water specimen collecting from different location by covering up ceramic head of soil solution collector in undercurrent wetland to discuss.The water from the soil solution collector view results,if neglect ceramic head filtration effect on SS and the filtration effect by the relativity between SS and else contamination,few exceptions,almost contamination concentration in all location can reach the B of 1 grade limit requirements of Beijing local standards DB11/307-2005 discharge standard of water pollutants.Therefore,preliminary identify,if DB11/307-2005 discharge standard of water pollutants in the requirements for the B of 1 grade limit for target,the runoff water which quality and quantity above-mentioned corresponding to the experimental subsurface flow wetland design scale is: the length direction from the inlet is 10m,the depth direction from the upper surface is 20cm.The finalization of the design of wetland area and the depth of the filler needs to be further studied.
