摘要:
悬浮快速过滤工艺作为合流雨污水溢流污染处理技术已有应用案例,但该工艺对晴天污水的处理效果尚未得到确认.在中国江南某市合流区域进行了晴天污水处理的现场中试,结果表明,悬浮快速过滤工艺对污水的悬浮颗粒物(suspended solid, SS)和化学需氧量(chemical oxygen demand, COD)具有较高的去除率.其中,SS去除率约为29.5%~58.3%,COD的去除率约为6.7%~42.6%.高滤速和小预处理单元水力负荷有利于提高悬浮快速过滤工艺的污染物去除率.进水水质也影响着处理效果.该工艺较适用于高SS和高非溶解态COD比例的污水,进水中极小粒径颗粒物(< 25μm)的比例是工艺对SS的去除率的限制因素,而进水中SS、非溶解性COD与极细粒径颗粒物(< 25μm)比例可作为工艺适应性的关键性指标.同时,将合流制溢流的悬浮快速过滤装置作为污水的预处理设施,对减少合流管沉积物具有重要意义.
Abstract:
The suspension rapid filtration process has been applied as a pollution treatment technology for combined sewage overflow, but the treatment effect on treating sewage during sunny days has not been confirmed. In this paper, we carry out the on-site pilot test of sunny sewage treatment in a combined sewage area (i.e. a certain city of Jiangnan). The test results indicate that the suspension rapid filtration process effectively removes the suspended solid (SS) and chemical oxygen demand (COD) in sewage, the removal rates of SS and COD are from 29.5% to 58.3% and from 6.7% to 42.6%, respectively. High filtration velocity and small hydraulic load of pretreatment unit are beneficial to improve pollutant removal efficiency of pollutants in the suspension rapid filtration process. The influent quality also affects the treatment effect. The process is more applicable to the treatment of sewage with high SS and insoluble COD ratio. The proportion of SS particles <25 μm in influent is also key limiting factors to the removal rate of SS. And, the ratio of SS, insoluble COD and ultra-fine particles (<25 μm) in influent can be used as key indicators of process adaptability. Meanwhile, the suspension rapid filtration device can also be applied as a pretreatment facility for sewage to treat the combined overflow, which is of great significance to reduce sediment in combined sewer pipes.
