2004-2010年自来水消毒副产物的研究

目的降低消毒过程中产生的二次污染物的量。方法对水源水质的现状进行探讨和研究,用管网末梢项目限制、不同消毒方式的组合和进行工艺改造,减少消毒剂用量等方法,降低了消毒过程中产生的二次污染物的量。结果通过改进,消毒副产物如氯仿由4.50×10-2mg/L降到6.60×10-3mg/L,氯酸盐由0.70mg/L降到0.20mg/L以下。结论气浮池、活性炭等工艺的使用、不同消毒方式的组合使用,在保证消毒效果的同时还能使消毒过程中产生的副产物得到很好的控制,确保供水水质。

Study on water disinfection by-products during 2004 to 2010

Objective To reduce the quantum of secondary pollutant during disinfection process. Method Studied and discussion the water quality status, adopting limit the peripheral of pipeline, using different combination disinfection modes, carrying on technology reformed , cutting down the water disinfection consumption, and reduced the quantmn of secondary poilulant. Results By reforming, the by - products such as chloroform reduced from 4. 50 ×10 ^-2mg/L to 6. 60 ×10^-3mg/L, chlorate reduced from 0.70mg/L to 0.20mg/L. Conclusions Adopting the technology of flotation tank and activated carbon, using different combination disinfection modes, ensured the disincentive effect and control the by - prod- ucts during the disinfection process at the same time, ensure water quality.
