无机盐对工业废水常规活性污泥生化处理法的影响

Effects of inorganic salt on conventional activated sludge

提出了无机盐氯化钠和硫酸钠对常规活性污泥生化处理法的活性污泥法的污泥活性质量和系统处理效率的影响 ,实验结果表明 :当NaCl、Na2 SO4的浓度分别达到 3.5 %和 4.5 %时 ,常规活性污泥生化处理系统的COD去除率要小于 % ,系统失去处理意义 ,同时 ,还表明系统耐Na2 SO4的能力高于NaCl,从而 。

Effects of two inorganic salts (sodium chloride and sodium sulphate) on conventional activated sludge were studied by treating industrial wastewater . Experimental,results indicated that the removal rate of COD is all below 50% when the concentration of NaCl and Na\-2SO\-4 is 3.5% and 4.5% respectively. And then,the salt\|resisting of Na\-2SO\-4 is higher than that of NaCl in the conventional activated sludge. In addition,it offered theoretical data for the engineering of conventional activated sludge.
