摘要
我国大部分给水处理厂主要采用混凝-沉淀-过滤-消毒的常规处理工艺,该工艺对有机物、氨氮等去除效果有限,同时存在消毒副产物残留等问题。根据我国经济发展现状,分析了常规处理工艺的改进措施,包括对常规工艺进行强化,在常规处理工艺之前增加预吸附和预氧化,在常规处理工艺之后增加臭氧-生物活性炭吸附、膜处理等。这些措施在保留原处理工艺的基础上,通过调整操作条件或增加处理设施来改善出水水质,具有投资少、见效快的特点。
The conventional treatment process （coagulation-sedimentation-filtration-disinfe-ction） used in most of the domestic drinking water plant couldn＆#39;t remove the organic pollutants and ammonia nitrogen completely, and had the problem of residue of disinfection by-products. After analyzing the improved processes according to the current situation of China＆#39;s economic develop-ment, some improved processes for micro-polluted water treatment were suggested, including enh-anced treatment process for conventional treatment process, increased preadsorption and preoxida-tion treatment at the front, ozone-biological activated carbon adsorption and membrane treatment at the behind of the conventional treatment process. The improved treatment processes improved the effluent quality through adjusting the operating conditions and increasing the processing facilities on the basis of the conventional treatment process, had the features of low investment and quick effect, could provide references for most of the domestic drinking water treatment plant tr-ansformation.
