To perform a systematic survey on the occurrence and removal of micropollutants during municipal wastewater treatment, 943 semi-volatile organic chemicals in 32 wastewater samples including influents of secondary treatments, secondary effluents and final effluents（effluents of advanced treatments）, which were collected from seven full-scale municipal wastewater treatment plants（MWTPs） in China, were examined by gas chromatography-mass spectrometry（GC-MS） coupled with an automated identification and quantification system with a database（AIQS-DB）. In total, 196 and 145 chemicals were detected in secondary and final effluents, respectively. The majority of the total concentrations（average removal efficiency, 87.0%±5.9%） of the micropollutants were removed during secondary treatments. However, advanced treatments achieved different micropollutant removal extents from secondary effluents depending on the different treatment processes employed. Highly variable removal efficiencies of total concentrations（32.7%–99.3%） were observed among the different advanced processes. Among them,ozonation-based processes could remove 70.0%–80.9% of the total concentrations of studied micropollutants. The potentially harmful micropollutants, based on their detection frequency and concentration in secondary and final effluents, were polycyclic aromatic hydrocarbons（PAHs）（2-methylnaphthalene, fluoranthene, pyrene, naphthalene and phenanthrene）, phosphorus flame retardants（tributyl phosphate（TBP）, tris（2-chloroethyl）phosphate（TCEP） and tris（1,3-dichloro-2-propyl） phosphate（TDCP））, phthalates（bis（2-ethylhexyl）phthalate（DEHP））, benzothiazoles（benzothiazole,2-（methylthio）-benzothiazol, and 2（3H）-benzothiazolone） and phenol. This study indicated that the presence of considerable amounts of micropollutants in secondary effluent creates the need for suitable advanced treatment before their reuse.

1城市污水再生利用的定位城市污水再生利用是一个高度复杂的系统工程,涉及政策导向、目标定位、用水途径、水质要求、技术选择、安全保障、经济效益、公众宣传、价格差异、付费原则等多个层面。从整体发展战略上看,再生水的开发利用具有资源循环利用和环境质量改善的双重属性,再生水的利用不仅可以增加有效供水量、缓解饮用水需求的增长,在缺水地区成为可靠的水源并降低用户的用水成本,而且可以削减排入水体环境的污染物总量。再生水的资源目标主要通过再生水的直接或者间接利用来实现,以缓解局部地区的缺水状况。从更深层次来讲,其重要功能是水污染物的削减,即再生水利用的环境战略属性。进一步延伸,就要更加强调整个污水的再生、复原过程,其目的不仅仅是污水的再生利用,而是水资源有效供给总量的最大化,这种最大化除了减少用水量和直接再生利用以外,更主要是强调通过人工强化的方式缩短水质的自然复原周期(见图1)。图1城市水源水质目标与再生水利用路径示意根据城市再生水利用的双重属性,制定再生水战略的时候,应该考虑得更为长远,通过再生水的各种利用方式,实现水体环境质量的整体改善,以保障饮用水水源的水质水量安全。

基于住建部城镇污水处理数据管理系统的水质数据，选定影响污水生物脱氮能力的关键水质参数BOD5／TN和SS／BOD5，分析城镇污水处理厂进水水质参数的空间分布特征及参数值，结果表明：我国70％城镇污水处理厂进水BOD5／TN低于4，59％城镇污水处理厂进水SS／BOI）5高于1．2，南部城市较北部城市碳氮比低，悬浮固体比例高，北京、上海、广州20万m3／d污水处理厂进水SS／BOD5维持在1．1～1．2的正常值。我国城镇污水碳氮比（BOD5／TN）偏低、进水悬浮固体无机组分含量偏高（SS／BOD5）的状况普遍存在，构成我国城镇污水的特有水质特性，在城市建设及污水管网尚不完善的区域，这种状况还会继续存在较长的时间，需要加以关注和解决。

氟调酸(fluorotelomer carboxylic acids,FTCAs)是全氟烷基羧酸(perfluoroalkyl carboxylates,PFCAs)的前体物,同时也是替代加工助剂.本研究应用固相萃取-液相色谱-三重四极杆质谱仪联用的检测分析方法,探究了中国5个城市9座城市污水处理厂进水、二沉池出水、三级处理出水和污泥中6种FTCAs和12种PFCAs的分布及排放特征.FTCAs在城市污水处理厂进水中的浓度为0.52—2.00×10^(3) ng·L^(-1),受纳工业废水的城市污水处理厂进水中FTCAs的浓度高于其他主要受纳生活污水的城市污水处理厂,表明工业废水的排放会影响城市污水处理厂中FTCAs的浓度水平.生物处理工艺对FTCAs和PFCAs的去除率分别为43%—93%和-40%—69%.∑FTCAs在三级处理出水及污泥中的总排放量为13.6 g·d^(-1),6:2 FTCA和8:2 FTCA为主要的组成物质.三级处理出水中FTCAs及PFCAs的风险商分析表明三级处理出水中6:2 FTCA、PFHxA、PFOA、PFNA和PFDA可能对鱼类存在潜在风险.本研究为我国城市污水处理厂中新污染物的管控提供了数据基础.
