近年来上海地区部分电厂工业废水中 CODcr超标排放较为突出。经分析主要是由于树脂再生废水中的CODcr值较高。主要针对上海地区电厂化学再生废水 CODcr的污染源 ,排放现状以及现有的废水处理设施进行了论述 ,并就其改造方案提出了几种对策 ,重点介绍了生物膜法处理工艺的起源、实质和特点 ,以及该工艺在电厂再生废水降低 CODcr处理中的可行性和优点 ,并以实验数据说明了生物膜法处理电厂化学再生废水的效果
In recent years, some of the power plant in Shanghai wastewater CODcr excessive discharge is more prominent. The analysis is mainly due to the higher value of CODcr in resin regeneration wastewater. This paper mainly discusses the sources of CODcr pollution in the power plant chemical regeneration wastewater in Shanghai and the current status of the wastewater discharge and the existing wastewater treatment facilities. Several countermeasures are put forward to improve the wastewater treatment plant, especially the origin, essence and characteristics of the biofilm process , And the feasibility and advantages of the process in reducing CODcr in power plant regeneration wastewater and using experimental data to illustrate the effect of biofilm treatment of chemical regeneration wastewater from power plants
