Abstract

Abstract:

Bio-contact oxidation process was applied to treat partly hydrolyzed polyacrylamides (HPAM) in simulation wastewater. Under the condition of HRT 38 h, DO 3～4 mg/L, testing inflow 0.38 L/h, the influence of temperature, inflow concentration of HPAM and carbon resource in wastewater on the remove of COD and degradation of HPAM were investigated. The results show that it is technical feasibility to treat polyacrylamides in simulation wastewater with the process. The average COD removal efficiency reached 60.1% and 56.5%,respectivily, at 37 ℃ and 45 ℃, meanwhile the average degradation rate of HPAM reached

63.2% and 57.0%. When inflow HPAM were 100 mg/L and 120 mg/L in wastewater, the average COD removal efficiency are 56.8% and 51.5%, the average degradation rate reached 59.7% and 55.5% during steady period. The testing results could meet the national second emission standards of wastewater.

摘要： 采用生物接触氧化法处理含聚丙烯酰胺(HPAM)的模拟污水。在水力停留时间38h,溶解氧(DO)
3~4mg/L,进水流量0.38L/h的条件下,考察了温度、HPAM 质量浓度和污水中碳源含量对模拟污水COD去除和
HPAM 降解的影响。结果表明,实验系统处于稳定运行阶段,温度为37,45 ℃时,平均COD去除率分别为60.1%,
56.5%,平均HPAM 降解率为63.2%,57.0%;进水HPAM 质量浓度为100,120mg/L时,平均COD去除率分别为
56.8%,51.5%,平均HPAM 降解率为59.7%,55.5%,处理效果均能满足国家污水二级排放标准的要求。
