高效氧化技术与微生物技术耦合去除工业废水中锰、铬、氨氮

摘要

利用锰盐深加工工业废水作为研究对象,采用微电解、双氧水、臭氧复合氧化技术对重点污染指标锰、铬、氨氮进行前期预处理,通过考查3种氧化预处理技术对废水中锰、铬、氨氮的去除率,确定了该工艺的可行性,解决了高含量锰、铬、氨氮对生物处理的严重抑制问题.充分发挥了生化系统对污水处理的应用,实现氧化技术与微生物技术完美耦合,最终锰、铬、氨氮去除率均达到99％.排放浓度与排放总量均满足国家相关企业排污要求.%By using manganese salt in deep processing of industrial wastewater as a research object,we will take micro electrolysis,hydrogen peroxide,ozone oxidation technology for the key pollution indicators of manganese,including chromium,ammonia nitrogen into pretreatment.In examining three kinds of technology of oxidation pretreatment in waste water of manganese,including chromium,ammonia nitrogen removal rate to determine the feasibility of this technology.We try to solve the high content of manganese,chromium,ammonia nitrogen for biological treatment of severe rejection problem.In giving full play to the application of biochemical system for sewage treatment,we have achieved perfect coupling oxidation technology and microbial technology.Eventually,we know that manganese,chromium,ammonia nitrogen removal rate can achieve 99％.The discharge concentration and total emissions can satisfy the requirements of relevant national enterprise pollution.
