摘要:
针对日益严重的水体藻类污染问题,本试验分别选用粉末活性炭(PAC)、超滤(UF)及其组合工艺对富藻水体藻类物质(铜绿微囊藻)去除特性进行了研究。实验结果表明单独的粉末活性炭工艺即使在高投加量情况下(PAC投加量为120 mg/L)对藻类物质去除效果不佳;单独的超滤膜工艺虽然对藻类物质有较好的去除效果(去除率达到95%),但是膜污染较为严重;粉末活性炭与超滤联用工艺在PAC投加量为15 mg/L时,对铜绿微囊藻的去除率不低于99.99%,该工艺运行稳定,且可有效减缓膜污染。
As a response to the worsening water contamination by algae, the characteristics of individual and integrated process of powdered activated carbon(PAC) and ultrafiltration(UF) for removal Microcystic aeruginosa were respectively studied in the experiment. The results showed that the individual process of PAC was ineffective to remove the algae. Although the process of UF was efficient, and the removal rate could achieve 95%, the problem of membrane fouling was fairly serious. However, the removal rate of PAC-UF integrated process could reach as high as 99.99% when the dosage of PAC was 15 mg/L, which operated stably and effectively alleviated membrane fouling.
