| 摘 要： | 以糖蜜酒精废液为材料,通过梯度稀释和序批式酸化实验,研究了含硫酸盐高浓度有机废水的一般酸化规律.结果表明,糖质废水酸化的挥发酸(VFA)组分以乙酸和丁酸为主要形式;VFA对硫酸盐还原的完全抑制浓度介于23553～35241mg/L(以COD计)之间;VFA对产酸过程的反馈抑制浓度介于35241～37109mg/L之间;不同稀释度废水酸化后的可生化性提高幅度平均为10%.

| Abstract: | By using the molasse alcohol wastewater as material, the general acidification rule of containing high concentration of organic wastewater sulfate was studied. The acidification experiment of the original high concentration wastewater was carried out with dilution by gradient and batch type with the conclusions as follows: Acetic acid and butyric acid were the main forms of volatile acid (VFA) components of the alcohol wastewater acidification. The overwhelmingly inhibition concentration of VFA to sulfate reduction was between 23553~35241mg/L (counted with COD); the back-feed inhibition concentration of VFA to acid producing process was between 35241~37109mg/L; The biodegradability of different dilution wastewater after acidification was enhanced with an average range of 10%. |
