制浆废液污染特性变化对于生化处理系统的冲击与影响

Impacts of Alternating CTMP Effuluent on the Biochemical Treatment System and Its Adjustment

研究了阔叶木和针叶木两种原料交替更换使用时 ,化学机械法制浆废液污染特性变化对于生化处理系统的冲击与影响。本研究采用的活性污泥法处理系统具有高效菌类群体 ,对于针叶木和阔叶木两种原料的化机浆废液均有着良好的处理效果。当废液种类改变时 ,通过采取调控措施 。

Alternate utilization of softwood and hardwood often occurs in the CTMP plants due to the shortage of raw materials supply. The impact of the change of CTMP effluents on activated sludge process was discussed in this paper. Results showed that, under conditions of convenient adjustment operation, pollutants in both softwood (Epinette) and hardwood (Tremble) CTMP effluent could be effectively removed. Operating under dominant species of microorganism community, the activated sludge system showed relative flexible adaptability.
