【摘要】 本实验采用厌氧折流板反应器(ABR)对碱法草浆中段废水进行了水解酸化预处理的研究。结果表明:碱法草浆中段废水经过厌氧折流板反应器的水解酸化预处理后,可以提高其可生化性,其最佳工艺条件为:HRT=8h,pH=7,温度为25～35℃;污泥的VSS/SS=0.85、SVI=85.1,具有一定的活性和良好的沉降性能;出水水质优于初沉池。更多还原

【Abstract】 The experiment makes use of Anaerobic Baffled Reactor (ABR)in the study of hydrolysis-acidification pretreatment on alkali straw pulp bleaching effluent. The results show that the potential biochemical capability of alkali straw pulp bleaching effluent is improved by hydrolysis-acidification pretreatment with ABR. The best technical condition is: HRT=8h, pH=7, temperature at 25-35℃, VSS/SS=0.85, SVI=85.1, sludge with certain activity and nice sinking performance, water quality exceeds that in the preliminary sedimentation tank.更多还原
