采用二级混凝-气浮-水解酸化-SBR-过滤工艺,对某汽车制造厂的混合废水(包括脱脂废水、电泳废水、磷化废水和生活污水等)进行处理.经过对处理工艺进出水主要水质指标连续1个月的监测,发现COD去除率可达92.5%, SS去除率可达95.2%, NH3-N去除率可达58%, TP去除率可达96.7%,出水水质符合国家《污水综合排放标准》(GB 8978-1996)一级排放标准,吨水处理成本为1.6元/t,系统运行稳定,具有明显的经济、环保和社会效益.
採用二級混凝-氣浮-水解痠化-SBR-過濾工藝,對某汽車製造廠的混閤廢水(包括脫脂廢水、電泳廢水、燐化廢水和生活汙水等)進行處理.經過對處理工藝進齣水主要水質指標連續1箇月的鑑測,髮現COD去除率可達92.5%, SS去除率可達95.2%, NH3-N去除率可達58%, TP去除率可達96.7%,齣水水質符閤國傢《汙水綜閤排放標準》(GB 8978-1996)一級排放標準,噸水處理成本為1.6元/t,繫統運行穩定,具有明顯的經濟、環保和社會效益.

The study adopted two stages coagulation & floculation-air floatation-hydrolysis &acidification-SBR-filtration process to treat the mixed wastewater (including degrease wastewater, electrophoresis wastewater, phosphorus wastewater and sewage, etc. for one of automobile manufactories. After one month's continuous monitor and test, the result indicated that the removal rate of COD can reach 96.7%, the removal rate of SS can reach 95.2%, the removal rate of NH3-N can reach 58%, the removal rate of TP can reach 96.7%. The discharge quality can comply with Integrated Wastewater Discharge Standard (GB8978-1996) class I. The treatment cost is RMB1.6 yuan per ton wastewater. The system runs stably and has evident economic, environmental and social benefits.
