针对电子和光伏产业废水成分复杂、可生化性差、氨氮和氟化物浓度高的特点,研发并设计了一套高效化学法除氨氮除氟+超滤、反渗透双膜深度处理制得回用水的资源化集成处理新工艺,该工艺在太湖流域无锡某大型电子企业进行了规模化实践,结果表明运营安全可靠,长期效果良好。该研究可为我国电子及光伏行业废水再生回用和实现节能减排提供重要的借鉴和参考。%On the basis of the electronic and photovoltaic industry wastewater with complex composition,poor biodegradability,high concentration of ammonia nitrogen and fluoride,a set of new process for water resource utilization was developed and designed,which integrated the efficient chemical method for removing ammonia and fluoride with ultrafiltration and reverse osmosis embrane system. Large-scale practice was conducted in an electronic enterprise in Taihu Lake Basin. The results show that the process operation is safe and reliable with the long-term effect. This paper might provide an important reference for the reclamation and reuse of electronic and photovoltaic industry wastewater,as well as the target of energy conservation and emissions reduction in China.
