A treatment process of air flotation-hydrolysis acidification-UASB-AB was proposed aiming at the high concentration wastewater in the production of high density fiberboard.Engineering operation results showed that the average efficiency of COD,BOD,SS was 99.27%,99.63%,99.38%,respectively,and effluent quality to achieve the "integrated wastewater discharge standard"(GB 8978-96) level standards,processing costs of 1.20 yuan/t (winter,1.93 yuan/t).%针对某企业在生产高密度纤维板过程中排放高浓度废水的情况,提出了气浮-水解酸化-UASB-AB法处理工艺.工程运行结果表明,化学需氧量(COD)、5日生化需氧量(BOD5)、悬浮物(SS)的平均处理效率分别为99.27%、99.63%、99.38%,出水水质达到《污水综合排放标准》(GB 8978-96)一级标准,处理成本为1.20元/t (冬季1.93元/t).
