HRT对折流板式厌氧生物反应器处理印染废水的影响

基金项目: 江苏省环境工程重点实验室科研开放基金课题(ZX2014001);国家水体污染控制与治理科技重大专项(2011ZX0701003);江苏省太湖水污染防治办公室项目(JSZC-G2013-177)

Effects of HRT on the Treatment of Printing and Dyeing Wastewater by ABR

  • 摘要: 针对印染废水水质水量变化大、ρ(BOD5)/ρ(CODCr)低、色度高的特点,以苏南某污水厂(印染废水比例大于90%)调节池出水为研究对象,开展ABR(折流板式厌氧生物反应器)处理印染废水试验,处理规模为2 L/h,重点考察不同HRT(水力停留时间)下ABR对CODCr、色度的去除和对ρ(BOD5)/ρ(CODCr)的提升效果. 结果表明:①当进水平均ρ(CODCr)为517 mg/L、色度为380倍、ρ(BOD5)/ρ(CODCr)为0.20时,随着HRT(32、24、18、14和10 h)的缩短,CODCr平均去除率由46.1%降至22.5%,色度平均去除率由60.6%降至51.0%,出水ρ(BOD5)/ρ(CODCr)由0.39降至0.30. ②随着格室数量的增加,ρ(CODCr)和色度逐渐降低,其中第1格室的CODCr和色度的去除率分别占总去除率的20.0%和51.0%,紫外-可见吸收光谱扫描也证明了这一点. ③经过ABR厌氧水解后污染物种类明显减少,说明ABR厌氧水解作用较好,可为后续好氧工艺奠定基础.
