介绍了美国某给水厂的臭氧-生物活性炭深度处理工艺、主要构筑物、设计参数和运行效果。实验结果表明:原水中TSS、BOD5、COD、UV254和浊度平均值分别为18.25 mg/L、5 mg/L、7.34 mg/L、0.08和17.38 NTU,经过系统处理后的出水指标分别为1.33 mg/L、2 mg/L、0 mg/L、0.01和0.86 NTU,相应的平均去除率分别为88%、60%、100%、88%和81%。净水效果明显,五项常规指标均满足我国《生活饮用水卫生标准》(GB5749-2006)使用要求,这种深度处理技术及设计思路值得国内给水处理行业参考借鉴。 The ozone - biological activated carbon depth treatment process, main structures, design parameters and operating results of a US water supply plant are introduced. The experimental results showed that the average values ​​of TSS, BOD5, COD, UV254 and turbidity in raw water were 18.25 mg / L, 5 mg / L, 7.34 mg / L, 0.08 and 17.38 NTU, respectively, and the effluent indexes after system treatment were 1.33 mg / L, 2 mg / L, 0 mg / L, 0.01 and 0.86 NTU, respectively. The corresponding average removal rates were 88%, 60%, 100%, 88% and 81%, respectively. Water purification effect is obvious, five conventional indicators to meet China’s “drinking water health standards” (GB5749-2006) use requirements, this depth treatment technology and design ideas worthy of the domestic water treatment industry reference for reference.
