摘要
针对焦化生产环境污染和资源浪费严重的情况,国家自2005年1月1日起实施《焦化行业准入条件》,要求焦化废水经处理后要做到内部循环使用。焦化废水的处理主要采用一级预处理和二级生化处理。目前国内较先进的焦化废水处理技术有A2/O、固定化高效微生物处理技术(3T-AF/BAF)等。
In relation to the environmental pollution and serious waste of resources in coking production, the state implemented Access Condition of Coking Industry since January 1, 2005, asking coking wastewater treated for internal recycling. The treatment of coking wastewater mainly contains pretreatment and secondary biochemical treatment. A^2/O and immobilized efficient microbial treatment technology are the advanced technologies treating coking wastewater in our country currently.
