摘要
介绍了一种溢流雨污水就地消纳生态控污结构的设计方法,在考虑受纳水体环境要求的条件下,通过数值模拟与经验公式综合确定处理规模以控制用地面积;采用竹炭材质的短管作为核心填料以保证净化效果,经试验验证,其对COD、SS的平均去除率分别可达到35%和50%以上;利用生态型透水砖作为构筑物立面结构,根据该地区平均无雨时间间隔确定透水系数,在延长停留时间、强化净化效果的同时保证再次降水时的安全容积。该设计方法可为国内同类溢流雨污水控制提供参考。
A design method of ecological control structure for on-site treatment of combined sewer overflows was presented. Considering the environmental requirements of receiving waters, the treatment capacity was determined to control the area of land through numerical simulation and empirical formulas. Tubular bamboo charcoal was used as the core filler of the structure to ensure purification effect. Experi- ments showed the average removal rates of COD and SS were above 35% and 50% respectively. Ecologi- cal permeable bricks were used as a part of the wall. Its permeation coefficient was designed using the mean time between two rain events. The contact time could be prolonged to strengthen the purifying effect, and the capacity could be ensured before the next rainfall. This design method was introduced to provide reference for controlling combined sewer overflows.
