废水中的药物和个人护理产品(PPCP)对人类健康和水生态系统的负面影响已经成为一个新出现的问题。选取松花江沿岸的两个大型城市污水处理厂和工业污水处理厂，对12个污水处理厂的日内动态、季节变化和去除效果进行了研究。我们的结果表明，所选择的PPCPs在进水和出水中经常被检测到。进水中以咖啡因为主，而出水中以TCS为主，说明污水处理厂中不同类型的PPCPs命运不同。对进水中PPCPs的日内动态进行了评价，结果表明，12种PPCPs因其使用模式不同而可分为三类。对污水处理厂中PPCPs浓度的季节变化分析表明，一些PPCPs的浓度受化学物质的使用、降解和温度的影响。PPCPs的去除效率很高，1号污水处理厂为70.0%~99.7%，2号污水处理厂为62.5%~99.4%。PPCPs去除效率存在明显的季节变化。基于两个污水处理厂的PPCP质量负荷，我们的结果表明，与郊区的PPCP相比，城市中心的1号污水处理厂获得了更多的PPCP，这表明服务人口的影响。(C)2018爱思唯尔B.V.保留所有权利。
Pharmaceuticals and personal care products (PPCPs) in wastewater have become an emerging issue due to their negative effects on human health and aquatic ecosystems. Two full-scale municipal and industrial wastewater treatment plants (WWTPs) along the Songhua River were chosen to evaluate the intra-day dynamics, seasonal variations and removal of 12 selected PPCPs. Our results suggested that the selected PPCPs were frequently detected in the influent and effluent. Caffeine was the predominant compound in the influent; while the selected PPCPs was dominated by TCS in the effluent, suggesting the different fates of selected PPCPs in the WWTPs. The intra-day dynamics of PPCPs in the influent were evaluated, suggesting that the 12 PPCPs can be grouped into three categories because of their different use patterns. The analysis of seasonal changes of PPCPs concentrations in the WWTPs suggested that the concentrations of some PPCPs were influenced by the chemical usage, degradation and temperature. The removal efficiency for the PPCPs were very high with the values ranged from 70.0% to 99.7% for WWTP#1, and from 62.5% to 99.4% for WWTP#2. Significant seasonal variations of PPCPs removal efficiency were observed. Base on the mass loading of PPCPs in the two WWTPs, our results suggested that WWTP#1 in the urban core received much more PPCPs in comparison to WWTP#2 in the suburban regions, suggesting that influences of the service population.
