强化常规工艺处理长江南京段水源水试验研究

Experimental Study on the Enhanced Conventional Water Treatment Process for the Raw Water of Yangtze River in Nanjing Section

采用以生物活性滤柱为核心的强化常规工艺处理长江南京段水源水,中试试验结果表明:强化常规工艺能有效地去除水中的浊度,CODMn,NH3-N及NO-2-N,去除率可分别达到95%,70%,80%及90%。对UV254,溶解性有机碳(DOC)及可生物降解溶解性有机碳(BDOC)的去除率可分别达到50%,75%,60%,工艺对分子量小于1k的溶解性有机物(DOM)去除效果良好。强化常规工艺可对常规水厂改造提供一定的思路。

This study utilized enhanced conventional water treatment process cored by biological active filter column for the raw water of Yangtze River in Nanjing section. The result of pilot test showed that the conventional process could effectively remove the turbidity, NH3-N, NO2--N, CODMn, UV254, BDOC and DOC in water, and the removal rate of which were 95% , 80%, 90% , 70% , 50% , 60% and 75% , respectively. This process also had good effect on the removal of DOM （with molecular weight less than lk Dalton）. This enhanced conventional water treatment process could be used for reference in the transformation and upgrading of conventional water plant.
