| 摘 要： | 粪尿污水是生活污水中污染物的主要贡献者,它的单独净化处理是污水分散处理的重点和核心之一。但目前高浓度粪尿污水的单独处理技术尚有待研究。文章采用114LUASB反应器、以啤酒厂UASB反应器内的污泥为接种污泥,研究了在30℃条件下连续日处理413L和间歇日处理118L粪尿污水的净化效果,探讨了UASB用于人粪尿污水处理的可行性。UASB反应器水力停留时间控制在6.65h,连续运行结果表明,在SLR从0.36kgCOD(/kgVSS·d)逐步增加到2.29kgCOD(/kgVSS·d)的过程中,COD的去除率稳定在88.82%～96.84%。3d左右的负荷冲击不会导致反应器处理效果明显下降。未经沉淀预处理的高SS对反应器净化没有不良影响。间歇运行结果表明,出水COD浓度较连续进水时低。

| Abstract: | Experimental treatment of toilet wastes or black-water(mainly feces and urine),is conducted using a laboratory bench-scale up-flow anaerobic sludge blanket(UASB)reactor.Influents of black water with COD ranging from 500mg/L to 2,000mg/L are treated in both continuous and intermittent runs.The continuous test lasted for six months with an up-flow velocity of 17.14m/h and HTR of 6.65h,showing the COD removals ranged 88.82%～96.84% and no detrimental effect arising from high SS in the influent due to skipping pre-sedimentation.UASB performance and production of methane under the intermittent operation condition were studied as well. |
