摘要
本文就不同的净水处理引起的水中有机物分子量分布的变化进行了探讨。混凝处理去除大分子有机物,粉末活性炭不仅能有效地去除小分子有机物,对大分子量的有机物也有很好的去除效果。臭氧主要氧化大分子有机物,生物预处理由于微生物新陈代谢产物的影响,没有分子量变化的规律性。根据水源有机物分子量分布和净水处理去除不同分子量有机物的特点,可达到净水处理工艺的最佳组合。
The characteristics of change in molecular weight(MW) distributions in wzter by various drinking water treatments were investigated in this paper. Coagulation treatment was effective in removing higher MW organics and powder activated carbon was effective in removing both lower and higher MW organics. In ozonation treatment, the organics with higher MW was oxidized. Because of influence of microbal metabolism products, no clear regulation in change of MW distribution by biological pretreatment was found. Based on organic MW distribution of water source and characteristics of removing various MW organics by drinking water treatment, the optimal combination of drinking water treatment process for removing organics can be achieved.
