题目：浅谈青岛重质油加工研究中心炼油废水处理工艺与运行管理方案1 浅谈青岛重质油加工研究中心炼油废水处理工艺与运行管理方案摘要我国水资源贫乏且地表水污染较严重.工业废水是影响地表水环境的重要因素之一.而炼油废水是工业废水的一种,油产品的冶炼制造、提取加工及油品水洗等过程中产生的一类废水，其有机物质多，难降解，毒性大已成为炼油废水处理的主要特点。近年来,我国石油化工工业得到了快速的发展,随之而来的是炼油污水排放量的连年增加.那么炼油废水的处理就成为急需解决的问题。并且通过长时间的运营操作发现此行业的污水处理经验，结合所学理论知识相结合，做出对现有污水处理工艺的改进，在达到现有出水指标的前提下，节约了生产成本，简化了运营管理操作，为生产创造了效益。关键词炼油废水特征危害原理工艺水回用 2 Abstract China is not only a country（omitted）r resource shortage but also a country with serious surface-water pollution.
