| 摘 要： | 本文研究了几种水处理氧化剂——氯气、二氧化氯、臭氧对原水中不同龄期摇蚊幼虫的灭活效果,并进一步考察了预氧化与水处理澄清过程对1龄幼虫的协同去除效果.研究结果表明:随龄期的增长摇蚊幼虫对化学氧化剂的耐受性不断增强,与其它2种氧化剂相比,二氧化氯对摇蚊幼虫具有更好的灭活作用.二氧化氯投加量0.5 mg.L-1,二氧化氯预氧化与水处理澄清过程的协同作用可以完全去除水中生物活性降低的1龄幼虫;混凝沉淀工艺能够完全去除原水中2-4龄幼虫,二氧化氯投加量1.0 mg.L-1,原水中4龄幼虫经混凝沉淀后在24h内死亡.试验证明化学预氧化剂的氧化灭活与其他水处理工艺有机结合,发挥协同作用,是解决摇蚊幼虫污染问题的基本策略.

| Abstract: | The killing effects of several oxidants,including chlorine,chlorine dioxide and ozone on the different instar larvae of chironomid in source water were investigated.In addition,the cooperation removal effect on the first instar larvae of chironomid was also evaluated after pre-oxidation by oxidants,followed by clarification process.The results showed that the tolerance of chironomid larvae on oxidants was strengthened with the increase of instar.chlorine dioxide possessed better killing effect than the othe... |
