摘要
Abstract
In response to the issues of poor biodegradability,high pollutant concentration,and elevated treatment cost associated with high-strength organic wastewater containing Polyvinyl Pyrrolidone(PVP)generated during ultrafine silver powder production,a combined process of"enhanced biological pretreatment+molecular sieve membrane"was developed by optimizing conventional biochemical treatment and integrating a novel organic molecular sieve membrane system.Application results show that this process achieves an overall removal rate of over 95%for Chemical Oxygen Demand(COD),and approximately 90%for both ammonia nitrogen and total nitrogen.The proposed process exhibits stable operation,high treatment efficiency,and favorable economic performance,providing technical support for the engineering treatment of high-concentration PVP-containing organic wastewater.关键词
