摘要
本文对国内二种草浆CEH漂白废水的特性进行了较详细的分析研究。研究表明 ,两种草浆CEH漂白废水呈较强的酸性 ,COD与BOD5 之比小于 0 .2 ,Cl-含量高 ,不适合于传统的生物氧化法直接处理。废水中的高分子有机物污染物是废水色度的主要来源 ,两种废水的色度和 pH值密切相关。亚硫酸盐浆CEH漂白混合废水GC -MS分析结果表明 ,各种氯代苯、氯代苯酚。
The characteristics of two kinds of typical effluents from gramineae pulp CEH bleach processes were studied. Both kinds of effluents were acidic, the contents of chloride anion were very high and the ratio of BOD 5 to COD was less than 0.2, the characteristics of the effluents indicated that they were not susceptible to traditional bio_oxidation treatment. The high molecular organic pollutants in the effluent were the main source of color, and the color had close relationship with the pH value of the effluent. GC_MS analysis of the effluent from CEH bleach process of sulfite pulp revealed that chlorobenzenes, chlorophenols and chloroguaiacols were the typical toxic low molecular organic pollutants in the effluent.
