超效浅层气浮在造纸废水处理中的应用

Application of super-efficient shallow air-floating to the treatment of wastewater from papermaking

在造纸废水处理中,悬浮物(SS)的去除是废水处理工艺选择时考虑的重点。实践表明,超效浅层气浮代替传统气浮设备,提高了SS的去除率,采用超效浅层气浮—好氧的废水处理工艺,可使造纸废水达到《污水综合排放标准》一级排放标准。

In the papermaking wastewater treatment,the removal of SS is the key to the treatment process.The practical operation shows that the super-efficient shallow air-floating can substitute the traditional air-floating and improve the removal rate of SS.By the super-efficient shallow air-floating/aerobic process treatment system,the effluent quality has reached the first grade standard of comprehensive effluent discharge.
