摘要：

目前焦化废水处理的A2/O（O）工艺已不能满足环保要求的出水指标。在工程总结和现场考察的基础上，提出4种焦化废水处理提标改造的实用技术：预曝气技术、生物流化床技术、初生吸附技术和二沉池更新换代技术。经过工程实践证明，4种技术均可降低成本，使焦化废水处理稳定达标，具有推广意义。

关键词: 焦化废水, 预曝气, 初生吸附, 生物流化床, 高效沉淀池

Abstract:

The A2/O(O) process of coking wastewater treatment has not been able to meet the requirement of environmental protection.On the basis of engineering summary and on-site investigation, four kinds of practical technologies for coking wastewater treatment are put forward: i.e.pre-aeration technology,biological fluidized bed technology,primary adsorption technology and secondary sedimentation tank upgrading technology.The project utilization shows that all the four technologies can not only reduce cost to a certain extent,but also ensure the stability of the treatment up to specification,which can be largely promoted.
