| 摘 要： | 考察了乙酸盐（钠）含量对循序间歇式废水生物脱氮除磷工艺的氮、磷去除效果及污泥沉降性能的影响。试验结果表明，废水中乙酸盐（钠）含量对ＰＯ＾３－４－Ｐ，ＰＮ＾－ｘ－Ｎ的明显。随着乙酸盐（钠）浓度的增加，ＰＯ＾３－４－Ｐ及ＮＯ×－Ｎ的去除率相应提高。乙酸盐（钠）的最低起始浓度为１２５ｍｇ／Ｌ，但超过２１５ｍｇ／Ｌ后，便产生污泥膨胀现象。

| Abstract: | In this paper, the effects of acetate on biological N and P removal rates and activated sludge settleability were studied. A sequential biological batch reactor (SBR) was used. Experimental results demonstrate that:Acetate has morde effects on PO43--P and NOx--N removal than on NH4+-N removal. The removal rates of PO43- and NOx--N became higher with increase in initial acetate concentrations. The least required initial concentration of acetate is 125×10-6. As the initial acetate concentration reached 215×10-6, the bulking of activated sludge occured. |
