【摘要】 对比研究了预加氯和未预加氯两种条件下原水水质在输送管道中的变化规律。结果表明,原水预氯化可以抑制藻类在管道中的生长繁殖,并提高原水的溶解氧浓度。原水预氯化会生成多种有害副产物,增加水的致突变活性,形成大量对人体有害的卤代有机物,因此氯的投量不宜过大。更多还原

【Abstract】 Variations of raw water quality in distribution pipes were compared with and without pre-chlorination. The result shows that prechlorination can effectively control algae and increase dissolved oxygen. Prechlorination results in many kinds of harmful by-products, addition of mutagen and formation of halogen organics which is harmful to human beings.更多还原
