染料、颜料废水中盐度对生化系统的影响

归纳总结了染料、颜料废水中盐度发生变化时生化系统CODCr消耗量的变化情况,通过数据分析得出,当废水中盐度小于1%时,生化系统运行稳定,污泥活性高;当废水中盐度大于1%时,污泥解体,生化系统CODCr消耗量降低到正常处理量的39%。

The paper summarized the efficients of CODCr removal of biochemical system when the salinity of dye and pigment wastewater changed. Based on the data analysis, when the salinity of wastewater is less than 1%, the biochemical system operates stably, and activated sludge is highly efficient. When the salinity of wastewater is more than 1%, sludge disaggregation appeared in large amount,the removal amount of CODCr in the biochemical system was reduced to 39% of the normal removal amount.
