中央沙水库与青草沙水库原水水质特征与处理对策

Characteristics and treatment measures of raw water of Zhongyangsha Reservoir and Qingcaosha Reservoir

分析了中央沙水库和青草沙水库原水的水质特征,并对水厂现常规净水工艺提出了对策。增加前加氯投加量或在取水口投加粉末活性炭可以较好解决藻类爆发带来的嗅味问题。应用深度处理工艺不但可以较全面地解决水库原水在藻类爆发时常规净水工艺无法解决的出厂水嗅味问题,而且能大幅度改善自来水的口感,提高生物稳定性。

The quality characteristics of the raw water of the Zhongyangsha Reservoir and the Qingcaosha Reservoir were analyzed, and the countermeasures were put forward for the conventional water purification process in the water treatment plant. Increasing the dosage of prechlorine addition or dosing powder activated carbon at the water intake could better solve the smell issue caused by the outbreak of algae. The application of advanced treatment technology could not only comprehensively solve the issue of smell in treated water, but also improve the taste of tap water and had improved biological stability.
