摘要：采用混凝沉淀、活性炭吸附以及混凝沉淀+活性炭吸附工艺对焦化厂生化出水进行深度处理。单独混凝沉淀或活性炭吸附均可以将水样中COD降到100mg/L以下,达到国家污水一级排放标准和冷却用水建议标准。活性炭根据不同的材质和进水而表现出不同的吸附性能,对于焦化厂生化出水,煤质炭Ⅰ和果壳炭均表现出良好的吸附效果,并使出水COD<100mg/L,但处理成本较高。混凝沉淀+活性炭吸附工艺充分发挥适合去除大分子污染物的混凝沉淀与适宜去除小分子污染物的活性炭吸附技术两者的协同增效作用,吸附单元采用廉价的煤质炭,使出水水质达到个别生产或生活用水回用标准,并且降低深度处理成本。研究结果表明,混凝沉淀+活性炭吸附作为焦化厂生化出水回用工艺是经济可行的。
Feasibility of coagulation/flocculation/sedimentation （CFS）, carbon adsorption and CFS plus carbon adsorption for advanced treatment of a biotreated coking plant wastewater were determined. The CFS treatment alone was feasible and cost effective in producing an effluent meeting the reuse standard for cooling water （COD〈100 mg/L）. Effectiveness of carbon adsorption was dependent on both the carbon type and influent quality. The adsorption treatment of a biotreated sample using either coal or fruit nut based activated carbon also produced an effluent of COD〈100 mg/L; however the cost was much higher. The CFS＋carbon adsorption treatment process, which employs the CFS step to remove high molecular weight organic constituents of the feed followed by the adsorption step using a low cost coal based activated carbon to remove the residual organic pollutants, was an attractive advanced treat- ment process for producing a final effluent that may be reused for many beneficial purposes （COD〈50 mg/L）.
