组合工艺对水源水中有机物的去除研究

由于黄河水受污染严重，而以黄河水为源水的自来水厂，多数目前仍然沿用以除浊为目的的常规处理工艺，其出水水质不甚理想。利用移动床生物膜反应器预处理、常规处理及臭氧活性炭深度处理组合工艺处理黄河水研究表明，组合工艺各单元都能有效去除TOC, 组合工艺对TOC的总去除率的平均值为42.2%。组合工艺对UV₂₅₄、藻类、AOC 、 BDOC的去除效果十分理想。虽然原水的致突变性已经较低，组合工艺仍能有效地降低致突变性，其中预处理工艺对降低致突变性的效果较显著。

Research on Reduction of Organics in Polluted Source Water Using the Combined Process

Due to heavy pollution in Yellow River water,the finished water quality of most dinking water works taking Yellow River water as source water but using conventional treatment process,is not ideal.In this study the combined process was applied for the purification of Yellow River water,including biological pretreatment using moving bed biofilm reactor,conventional treatment unit,ozonation-activated carbon advanced treatment unit.The results indicated each unit of the combined process could effectively reduce total organic carbon(TOC)in waters and the average of total removal rate was 42.2%.Moreover,the combined process performed well in reduction of UV_ 254,algae,assmilable organic carbon(AOC),biodegradable dissolved organic carbon(BDOC),and the trihalomethane precursors.The combined could effectively reduce mutagencity in waters and the moving bed biofilm reactor played a significant role,although the mutagencity in raw water was low.
