摘要
结合水厂现有工艺,采用混凝沉淀超滤组合工艺处理北方地表水,为新建水厂以及现有水厂的改造提供技术储备。研究结果表明:超滤对浊度、细菌、大肠菌和总铁有很好的去除效果,但对有机物的去除效果有限,且能去除的主要为分子量>30 ku的有机物。根据现有条件进行经济分析得出,超滤单元的最高处理成本为0.27元/m3。
Coagulation and ultrafihration combination process was adopted for the treatment of surface water in North China, combined with existing process, in order to provide technical reserve for new waterworks and reformation of old ones. The results showed that ultrafihration （UF） had a good efficiency on the removal of turbidity, total bacteria, coliform, and total iron, but had a limited efficiency on the removal of organic matter with the molecular weight of more than 30 ku. The maximum cost of the UF unit was 0.27 Yuan/m^3 based on the economic analysis of existing situation.
