摘　　要：采用快速纤维过滤技术在南方某污水处理厂开展合流制溢流处理的中试研究,考察该技术对溢流污染物的去除效果。结果表明,溢流进水SS浓度值常高于COD浓度值,进水混合水样的非溶解性COD浓度为混合水样COD浓度的73.08%~90.0%;滤速不超过20.83 m/h时,SS负荷去除率大于60%,中试装置的水头损失不超过1 kPa;对于进水混合样的小粒径(<0.1 mm)悬浮物去除效果较好。该技术可应用于合流制污水处理厂的溢流预处理工艺,以及其他溢流处理需求的场所。In order to investigate the removal effect of rapid fiber filtration process to treat combined sewage overflow(CSO),the pilot test was carried out at a WWTP in southern area.The results show that the SS concentration values of CSO are usually higher than COD concentration values.For the mixed influent samples,a large proportion of COD is insoluble COD,with values from 73.08%to 90.00%.The SS load removal rate is more than 60%when the filtration rate is under 20.83 m/h.The water head loss of pilot plant does not exceed 1.0 kPa.The fine SS particles in mixed samples can be removed well.The study suggested that the rapid fiber filtration could be applied as a pre-treatment process to treat CSO at WWTP,and other places with treatment needs.
