水库水除臭试验研究及应用

Experimental study and application of removing odor in reservoir water

针对四川某水厂水库水源季节性藻类污染导致的嗅味问题,开展了臭氧氧化、活性炭滤柱吸附和投加粉末活性炭去除嗅味的试验研究。研究结果表明,3种方式均能有效去除水中的嗅味:在应急处置期间,可投加25 mg/L粉末活性炭;从长远利益考虑,新增炭砂活性滤池或臭氧-炭砂生物滤池,能解决高藻期的嗅味问题。

Aimed at the odor issue caused by seasonal algae contamination in the water source of a waterworks reservoir in Sichuan, ozone oxidation, activated carbon filter column and dosing PAC were applied and investigated. The results showed that the three methods could all effectively remove the odor in water: dosing 25 mg/L PAC could be taken during emergency disposal, but for long-term consideration, setting carbon-sand filter or ozone-carbon sand biological filter could solve the odor issue during the high-algae period.
