纳滤生产再生水示范工程运行效果分析
Operation effect of a nanofiltration demonstration project for producing reclaimed water
摘要
Abstract
As a promising advanced treatment process, nanofiltration(NF) is seen very competitive for producing reclaimed water.But so far, NF has rarely been used in municipal wastewater reclamation plants.In this paper, we tested the efficiency and stability of a pioneering NF demonstration project in Beijing, which targets producing reclaimed water from municipal wastewater.Results showed that the NF process can effectively remove chemical oxygen demand (COD), total phosphorus (TP) and heavy metals, with corresponding index of effluent meeting the requirement of the surface water standards, class Ⅲ.However, NF had relatively poor performance for total nitrogen (TN) removal, with a removal rate of less than 15%.The rejections of all trace organics were about or higher than 70% except for bisphenol A and carbamazepine, likely because of the low molecular weight and non-ionic properties of these two chemicals.Luminescent bacteria toxicity test proved the reliability of NF to produce nontoxic effluent.关键词
