摘    要:
针对目前焦化废水处理工程系统停留时间长、处理效率低的现状,采用自行研制的新型结构生物三相流化床来实现A/O2组合作为核心工艺,研究生物处理系统各个单元结构在焦化废水处理中的降解特性及耦合关系.结果表明,生物系统在总停留时间42 h下稳定运行时,厌氧流化床能有效提高焦化废水的可生化性;将废水的BOD5/CODCr(B/C)平均值从0.30提高到0.45,一级好氧流化床能高效降解有机污染物,对CODCr,和酚的平均去除率分别达到87.8%和99.9%,平均处理负荷分别为3.97 kg·m-3·d-1(以CODCr计)和1.01 kg·m-3·d-1(以酚计),二级好氧流化床对NH4 -N平均去除率达到89.9%.出水NH4 -N浓度稳定在15 mg·L-1以下.生物系统出水经过滤混凝沉淀工艺后达到<钢铁工业水污染物排放标准》(GB 13456-1992)中的一级排放标准.
