【摘要】 采用SBR工艺处理有机物含量低、氨氮含量高的城市污水,经过反复试验研究发现,该工艺对生活污水中氮、磷等污染物具有良好的去除效果。试验结果表明,采用试验水样平均进水水质为CODcr=197mg/L;BOD5=95mg/L;SS=203mg/L;NH4+-N=63mg/L;PO-34=1.3mg/L,各项污染物的平均去除率为:CODcr80%,BOD583%,NH4+-N75%,TP61%,处理后出水水质均能达到国家规定的排放标准(GB8978-1996),并提出了该工艺处理低碳高氮城市污水的最佳工艺条件。更多还原

【Abstract】 It is discovered that the SBR technique has excellent effect on removing of the phosphor and nitrogen in the civil waste water after repeated experiments.The result shows that the sample with following average attributes: CODcr=197 mg/L,BOD5=95 mg/L,SS=203 mg/L;NH4-N=63 mg/L,PO4-3=1.3 mg/L,can be up to the national first discharge standard(GB8978-1996) after the process of the treatment with the technique. Thereafter, the optimium operational conditions for the technique has been suggested to dispose the civil waste water with low carbon and high nitrogen.更多还原
