【摘要】 本文作者通过生产性试验考察了高锰酸钾复合药剂预处理技术在低温、低浊、高有机物含量的地表水处理中的助凝效果并与预氯化助凝进行了对比,还测得了两种处理技术所产生的氯仿量.试验表明,高锰酸钾复合药剂在助凝、减少氯仿生成量、降低有机物含量等方面,都具有比预氯化更好的效果.更多还原

【Abstract】 On the basis of field experiment the effect of composite potassium permanganate (CP) flocculating aid on pretreating surface raw water with low turbidity and high organic content at low temperature condition was examined arid compared with that of prechlorination flocculation. Also the content of chloroform residue produced during water treatmenting by both agents was observed. The findings show that better results will be obtained on flocculation process, reducing of organic content and chloroform formation for CP flocculating than prechlorination.更多还原
