| 摘 要： | 针对高盐度废水生物除磷的难点问题,采用生物/化学组合工艺处理高盐度、高磷、高氮的榨菜腌制废水,考察了运行工况、挂膜密度、排泥周期、药剂种类和投加量等对除磷效能的影响.试验结果表明:采用厌氧/生物除磷/生物脱氮/化学除磷组合工艺除磷高效、可行,当一级SBBR生物除磷单元的挂膜密度为60%、排泥周期为2 d、运行工况为进水(O.2 h)-厌氧(3 h)-好氧(6 h)-沉淀及排水(0.2 h),化学除磷单元按物质的量之比为9:1投加硫酸铝时,在进水COD及(PO3-4)-P分别为10 000 mg/L和38.5 mg/L的条件下,出水COD和(PO3-4)-P分别为90和0.1mg/L,去除率均达到了99%以上.生物除磷、生物脱氮、化学除磷单元的除磷分担率分别为56.6%、20.8%和22%.
