【摘要】 青藏线所处青藏高原,生态环境十分脆弱,污水排放要求高。因为高寒缺氧,污水温度低,限制了生物法在污水处理中的应用,需要研究适应青藏线情况的污水处理的新技术和工艺。根据青藏线类比水质检测情况和设计要求,采用了化学混凝膜过滤加催化电氧化的物化工艺流程进行现场试验,结果表明,处理后的污水水质达到了《生活饮用水水源水质标准》(CJ3020-93)二级标准。更多还原

【Abstract】 Qingzang railway lies in Qingzang highland, where entironment is vulnerable, and wastewater discharge standard is strict. Cold and poor oxygen and low water temperature restrict the application of biological process in wastewater treatment, it is needed that the new technology is studied to meet the conditions Qingzang railway. Basing on the determination of the analogous Qingzang railway wastewater and the design demands, the process of chemical coagulation membrane filtration linking electrical oxygenation with catalysis is used to experiment on spot, the results show that the treated wastewater quality achieve the second level of water quality standard for drinking water sources (CJ3020-93).更多还原
