摘要：以处理N,N-二甲基甲酰胺(DMF)的序批式好氧活性污泥系统为研究对象,污泥经200 mg/L的DMF模拟废水驯化后,向系统中分别投加40和80 mg/L的聚合硫酸铁(PFS),考察PFS对污泥有机毒性的影响。结果表明,PFS对活性污泥系统的处理效能有一定的促进作用,投加PFS后出水COD浓度可降低50%左右,同时污泥毒性也可降低30%左右;与投加40 mg/L的PFS相比,投加80 mg/L的PFS时出水COD浓度要低20%左右,但污泥毒性略高。
The aerobic sequencing batch reactor containing the toxic and refractory organic pollutant, N, acclimated through synthetic wastewater containing 200 the concentrations of 40 mg/L and 80 mg/L was added （SBR） was used to treat synthetic wastewater N-dimethylfonnamide （DMF）. The sludge was mg/L DMF, and polyferric sulfate （PFS） with into SBRs respectively. The effect of PFS on organic toxicity of sludge was investigated. The results showed that PFS had promoting effect on SBR performance. The COD in the effluent decreased by approximately 50%, and the sludge toxicity reduced by approximately 30%. By contrast, the COD in the effluent of the 80 mg/L PFS group was 20% lower than that of the 40 mg/L PFS group, while the sludge toxicity of the 80 mg/L PFS group was slightly higher than that of the 40 mg/L PFS group.
