摘　　要：以南方某流域水体可检出的SD、SMZ、HCB、马拉硫磷和BPA等新污染物为研究对象,进行复合新污染物共存的原水加标处理试验,研究预处理-常规处理-臭氧活性炭工艺处理效果。结果表明,SD、SMZ、BPA与COD_(Mn)均具有较好的相关性;生物预处理工艺对SD、SMZ、HCB、马拉硫磷和BPA去除率分别为23.97%、21.20%、6.08%、16.26%和23.76%,生物预处理最优停留时间是120min,最优气水比是1:2;常规处理工艺对SD、SMZ、HCB、马拉硫磷和BPA的去除率分别为18.02%、20.08%、23.02%、8.26%和16.53%,常规处理中SMZ和马拉硫磷的混凝剂最佳投加量为15mg/L,其余3种新污染物的混凝剂最佳投加量为20mg/L;深度处理工艺对SD、SMZ、HCB、马拉硫磷和BPA的去除率分别为49.13%、53.80%、60.20%、77.07%和71.50%,深度处理最佳臭氧投加量是3mg/L,最佳臭氧接触时间为24min,最优炭床停留时间是25min。试验工艺对复合新污染物具有良好的去除作用,对SD、SMZ、HCB、马拉硫磷和BPA的总去除率达到了69.86%、73.10%、73.65%、83.74%和82.72%,试验条件下出水的HCB、马拉硫磷和BPA满足《生活饮用水卫生标准》(GB5749-2022),出水的磺胺嘧啶和磺胺二甲嘧啶满足欧美发达国家的水质标准。Taking emerging pollutants such as SD,SMZ,HCB,malathion,and BPA that can be detected in a water basin in the south as the research object,a composite new pollutant co existing raw water spiking treatment experiment was conducted to study the treatment effect of pretreatment+conventional treatment+ozone activated carbon process.The results indicate that SD,SMZ,BPA and COD_(mn) all have good correlation.The removal rates of SD,SMZ,HCB,malathion,and BPA by the biological pretreatment process are 23.97%,21.20%,6.08%,16.26%,and 23.76%,respectively.The optimal residence time for biological pretreatment is 120 minutes,and the optimal gas water ratio is 1:2.The removal rates of SD,SMZ,HCB,malathion,and BPA by conventional treatment processes are 18.02%,20.08%,23.02%,8.26%,and 16.53%,respectively.The optimal dosage of coagulants for SMZ and malathion in conventional treatment is 15 mg/L,while the optimal dosage of coagulants for the other three new pollutants is 20 mg/L;The removal rates of SD,SMZ,HCB,malathion,and BPA by the deep treatment process are 49.13%,53.80%,60.20%,77.07%,and 71.50%,respectively.The optimal ozone dosage for deep treatment is 3 mg/L,the optimal ozone contact time is 24 minutes,and the optimal carbon bed retention time is 25 minutes.The experimental process has a good removal effect on composite new pollutants,with a total removal rate of 69.86%,73.10%,73.65%,83.74%,and 82.72%for SD,SMZ,HCB,malathion,and BPA.Under the experimental conditions,the HCB,malathion,and BPA in the effluent are better than the indicators specified in the Sanitary Standards for Drinking Water(GB 5749-2022),and the sulfamethoxazole and sulfamethoxazole in the effluent are better than the water quality indicators required by developed countries in Europe and America.
