Abstract:

In order to solve the problem that the quality of the treated styrene-butadiene rubber(SBR) wastewater couldn't reach the discharge standard,the experimental research on the follow-up treatment of the biochemically treated SBR effluent by Fenton reagent method has been conducted. The effects of influencing factors,such as initial pH,H₂O₂ dosage,n(H₂O₂):n(Fe²⁺) and reaction time on the removing rates of COD,phosphorus and SS are investigated. The results from Fenton treatment of SBR wastewater show that when the initial pH is 7,H₂O₂ dosage 0.4 mL,n(H₂O₂):n(Fe²⁺)2:1,and reaction time 70 min,the removing rate of COD is about 81% and the removing rates of phosphorus and SS are both nearly 100%. The effluent indexes could reach the first class criterion specified in Integrated Wastewater Discharge Standard(GB 8978—1996).

摘要：

为解决丁苯橡胶废水处理不达标问题,采用Fenton试剂法对丁苯橡胶废水生化出水进行后续处理试验研究,考察初始pH、H₂O₂投加量、n(H₂O₂):n(Fe²⁺)、反应时间对COD、磷和SS去除率的影响。结果表明:Fenton试剂法处理丁苯橡胶废水,在初始pH为7,H₂O₂投加量为0.4 mL,n(H₂O₂):n(Fe²⁺)为2:1,反应时间为70 min时,COD的去除率可达到81%左右,磷和SS的去除率接近100%。出水达到《污水综合排放标准》(GB 8978—1996)一级排放标准。
