纳滤膜工艺在太仓某水厂深度处理工程中的应用
Application of NF Membrane Technology in Advanced Treatment Project of a WTP in Taicang
摘要
Abstract
In order to supply"high quality"drinking water to citizens in Taicang,a water treatment plant(WTP)in Taicang selects low-pressure nanofiltration membrane technology for in-depth treatment,which is developed independently at home.It is put into operation in December 2019,with a scale of 50 000 m3/d.At the designed recovery rate of 85%,the average TOC of produced water by nanofiltration membrane is 0.10 mg/L and the concentration of residual aluminum is lower than 0.02 mg/L.The removal effect of dissolved organic matter such as tryptophan protein and microbial metabolites is significant.The average removal rates of TDS and total hardness are 24.78%and 30.64%.It shows that nanofiltration membrane can effectively intercept harmful substances,while retaining part of natural minerals beneficial for human body.The nanofiltration system has stable operation and good anti-pollution performance.The electricity and pharmaceutical cost of nanofiltration membrane system are only 0.236 yuan/m3,which one is a high-quality advanced treatment technology for drinking water.The WTP is the first drinking water purification project,which one removed organic matter by domestic nanofiltration membrane.It verifies the safety,stability and economy of domestic nanofiltration membrane treatment technology.关键词
