生物接触氧化法处理洗浴废水的研究

Study on the Treatment of Bathing Wastewater in Bio-contact Oxidation Reactor

利用生物接触氧化法处理洗浴废水,其载体为软性泡沫填料。研究了水力停留时间、气水比及CODCr容积负荷对CODCr、BOD5、LAS去除率的影响。结果表明:当水力停留时间为1h,气水比为1:1时,出水CODCr≤50mg/L,去除率为≥73.91%,BOD5≤10mg/L,去除率为≥77.32%,LAS≤1.0mg/L,去除率为≥90.89%,符合杂用水标准。CODCr容积负荷对洗浴废水CODCr、BOD5和LAS处理效果影响不大。

This paper used the bio-contact oxidation to treat the bathing wastewater ,and added to the soft foam filling in it.It researched the effect of hydraulic retention time,the ratio of gas to liquid and CODCr volume loading to the removal rate of CODCr, BOD5 and LAS. The results show that： when hydraulic retention time was 1 hour , the ratio of gas to fiquid was 1：1,the CODCr,BOD5, and LAS of enfluent water were ≤50 mg/L, ≤10 mg/L,and≤1.0 mg/L, and the removal rate of CODCr,BOD5 and LAS were ≥ 73.91%, ≥77.32% and ≥90.89%.The quality of the enfluent water met the requirement of Miscellaneous Domestic Water Quality Standard. The CODCr volume loading had less effected on the treatment of CODCr, BOD5 and LAS.
