三种净水工艺对加标污染物净化效果的中试研究

Pilot-scale Study on Treatment of Spiked Pollutants by Three Water Treatment Processes

为比较常规工艺、臭氧—生物活性炭工艺和膜处理工艺的净水效果,进行了有关重金属、农药和典型有机物的加标净水中试研究。结果表明,臭氧—生物活性炭工艺对有机物、农药、氨氮和嗅味物质的去除效果明显高于其他两种工艺;超滤膜对浊度、微生物和藻类的去除能力明显高于其他两种工艺;三种工艺对氯化物、硫酸盐、硝酸盐、溶解性总固体、氟化物和总硬度等指标均无明显去除效果。

In order to compare the water treatment efficiency of conventional process, ozone/biological activated carbon process and membrane treatment process, the pilot tests on heavy mental, pesticides and typical organic compounds were conducted. The results showed that the removal efficiency of organic compounds, pesticides, ammonia nitrogen and odorous compounds by ozone/biological activated carbon process was significantly higher than that by the other two kinds of processes. The removal efficiency of turbidity, bacteria and algae by ultrafiltration was significantly higher than that by the other two kinds of processes. The removal efficiencies of chloride, sulfate, nitrate, total soluble solid, fluoride and total hardness by the three kinds of processes were not obvious.
