摘要
将厌氧+好氧+超滤(UF)膜+光催化工艺用于养猪废水处理的试验研究,探讨了厌氧池水力停留时间(HRT)以及进水有机负荷变化对工艺处理效果的影响.结果表明,HRT为6 d时,该工艺对化学需氧量(COD)和氨氮(NH3--N)的去除率能达到93.64%和93.48%,并稳定在较高水平;在进水有机负荷变化情况下,工艺能够稳定出水COD在63.2～82.3 mg.L-1,COD,BOD,TP,NH3--N的平均去除效率为98.47%,98.06%,94.69%和93.78%,远低于畜禽养殖业污染物排放标准的一级标准,处理效果良好.
The main purpose of this study is to probe anaerobic ＋ aerobic ＋ UF membrane photocataly- sis technology for the treatment of piggery wastewater. Influence of anaerobictank hydraulic retention time and influent contaminants on waste water treatment efficiency were studied. The results showed that, when treated for 6 d, the removal rate of COD and NH3 -N was 93.63% and 93.48% respec- tively, and it is stable at high level. While organic loading of influent contaminants had a variation, ef- fluent quality of COD could stablize at 63.2 - 82.3 mg. L -1 , the effluent average removal rate of COD, BOD5 , TP and NH3 - N was 98.47% , 98.06% , 94.69% and 93.78% respectively, which were far below the primary discharge standard of pollutants for livestock and poultry breeding. There-fore the system has a good treatment effect.
