| 摘 要： | 采用管道混凝/超滤组合工艺深度处理回用水,考察了其处理效能及影响因素.结果表明,在相同条件下FeCl_3的混凝效果优于PAC的;组合工艺对COD_(Mn)和UV_(254)的去除率均随混凝剂FeCl_3的投量及混凝时间的增加而增大;组合工艺深度处理回用水的最佳工况:膜通量为64L/(m~2·h)、混凝剂FeCl3投量为7 mg/L、混凝时间为100 S,此时对浊度、COD_(Mn)和UV_(254)的去除率分别可达84.1%、28.6%和52.4%.

| Abstract: | The in-line coagulation/ultrafiltration process was adopted for advanced treatment of reclaimed water, and the treatment efficiency and influence factors were investigated. The results show that the coagulation effect of FeCl_3 is better than that of PAC under the same conditions. The removal rates of
COD_(Mn), and UV_(254) increase with increasing FeCl_3 dosage and coagulation time. The optimum conditions of the combined process are the membrane flux of 64 L/(m~2·h), FeCl_3 dosage of 7 mg/L and the coagulation time of 100 s. Under these conditions, the removal rates of turbidity, COD_(Mn), and UV_(254) are 84.1%,28.6% and 52.4% respectively. |
