摘要:以船舶含油废水重力除油罐出水为研究对象,采用混凝沉淀/好氧生物处理组合工艺对其进行处理,重点考察了高浓度的Cl^-对好氧生物系统处理效果的影响,以及由高浓度Cl^-引起的活性污泥生物相演替规律。结果表明,该组合工艺能在Cl^-浓度高达9256mg/L的条件下稳定运行,系统出水COD、TOC和石油类可分别降至(80~85)、(25~30)和(1.0~1.5)mg/L,达到了《污水综合排放标准》(GB8978-1996)的一级标准。高浓度的Cl^-对生物处理系统的影响较大,Cl^-为4000mg/L是对未驯化活性污泥产生抑制作用的转折点;在高Cl^-浓度下,降低Cl^-浓度比增加Cl^-浓度对生物处理系统的影响更大,良好的驯化过程和稳定的进水水质是高浓度Cl^-废水实现有效生物处理的重要保证。
After being treated by gravity oil-water separator, the marine oily wastewater was treated by the combined process of coagulation sedimentation and aerobic biological treatment. The effect of high Cl^- on the treatment efficiency of aerobic biological system and the Cl^- induced succession regulari ty of activated carbon biofacies were investigated. The results show that the stable operation of the combined process can be obtained at high Cl^- of 9 256 mg/L, the effluent COD, TOC and oil are reduced to 80 to 85 rag/L, 25 to 30 mg/L and 1.0 to 1.5 mg/L respectively, which reaches the first class discharge standard of Integrated wastewater Discharge Standard (GB 8978 -1996). The aerobic biological system is greatly affected by high Cl^-. Cl^- of 4 000 mg/L is a turning point for inhibiting unacclimated activated sludge. Cl^- decrease has a greater effect on the aerobic biological system than Cl^- increase under high Cl^-. Both well acclimation and stable influent quality are vital for effective aerobic treatment of high Cl^-wastewater.
