炼油化工企业节水减排的进展和存在问题

摘要

介绍了我国当前节水减排的形势和紧迫性,对最近炼油化工行业节水减排技术所取得的进展从以下7个方面做了简要的总结回顾：节水减排的＂三步法＂策略已得到逐步推广;水网络集成技术已逐步推广应用,并从工艺水夹点应用推向循环水夹点、循环水系统的节水减排深入发展、冷凝水高温回收技术应用、外排污水回用技术应用、＂零排放＂技术、水网络系统的在线实时监控管理等。对于当前节水减排工作中常见的存在问题,进行了梳理,从而给今后的节水减排工作指出方向。%The urgent demand of water conservation in our country is introduced.The recent progresses in water conservation and waste water reduction of chemical and refinery industries are retrofitted and summarized as 7 aspects.They are:"Three steps methodology for water conservation" popularized;applications of water network integration method;water saving in cooling water systems;high temperature recovery technologies of condensing water;zero liquid discharge;online real time monitory management of water network.The common problems in this area are listed and studied and thus directions of future development are pointed out.
