摘要
废水的水质特性是活性污泥数学模型研究和应用的重要方面。采用呼吸计量法及常规化学分析法对污水处理厂的废水特性进行了测定 ,通过研究发现 ,污水处理厂的曝气沉砂池出水中 SS占总 COD的比例平均为 10 .49% ;XS占总 COD的比例平均为 14 .2 4% ;SI 占总 COD的比例平均为 5 .5 2 %。初沉池出水中 SS占总 COD的平均比例为 9.62 % ;XS占总 COD的比例平均为16.97% ;Si占总 COD的比例平均为 11.3 8%。
Wastewater characterization is the important field of activated sludge model research and application. Respirometric analysis and general chemical analysis methods were adopted to analyse wastewater characterization. The results showed that the proportion of the readily biodegradable substrate of the effluent from the aerated grit chamber is 10.49%, the proportion of the particle biodegradable substrate is 14.21%; the proportion of the soluble inert substrate is 5.52%; and that the proportion of the readily biodegradable substrate of the effluent from the primary sedimentation pond is 9.62%, the proportion of the particle biodegradable substrate is 16.97%, the proportion of the soluble inert substrate is 11.38%.;
