| 摘 要： | 利用混凝/超滤中试系统处理高藻期滦河水,为了克服藻类对超滤膜系统的影响,采用预氯化措施,考察了其对中试系统处理效果的影响.结果表明,在有效氯投量为2 mg/L、混凝剂氯化铁投量为4 mg/L的条件下,预氯化/混凝/超滤工艺对COD_(Mn)和UV_(254)的去除率分别为51.6%和19.6%;预氯化在提高中试系统对有机物去除效果的同时,能够有效减缓膜污染,且膜出水中的消毒副产物和微囊藻毒素浓度均低于<生活饮用水卫生标准>(GB 5749——2006)的限值. |

| Abstract: | The coagulation/ultrafiltration process was used to treat the algae-laden raw water from Luan River.In order to overcome the influence of algae on the ultrafiltration system,the pre-chlorination method was used,and its effect on the treatment efficiency of the pilot system was investigated.The results show that under the conditions of 2 mg/L available chlorine and 4 mg/L ferric chloride,the removal rates of CODMn and UV254 are 51.6% and 19.6% respectively in the pre-chlorination/coagulation/ultrafiltration ... |
| Keywords: | ultrafiltration pre-chlorination algae membrane fouling disinfection byproducts |
