摘要
为研究废水厌氧处理过程中硫酸盐的去除机理,以厌氧折流板反应器(ABR)为工艺,考察了低碳硫比时,不同负荷和水力停留时间(HRT)下硫酸盐的转化规律。试验结果表明:硫酸根在前部隔室被大量还原。随着硫酸盐浓度的增加以及HRT的缩短,硫酸根的还原逐渐向后推移,之后硫酸盐的转化趋于平缓,CODCr的去除也有类似规律。硫离子浓度在前部隔室迅速上升至最大值,在之后的隔室中上下小幅度波动。碱度和挥发性脂肪酸(VFA)先在前部隔室迅速增加,然后在后部隔室缓慢下降。
An anaerobic baffled reactor （ABR） was adopted to study the transformation of the sulfate-containing waste water when the carbon sulfur ratio is 2 in order to present the removal mechanism of the sulfate. The results show that a large amount of the sulfate is reduced in the front compartments. Sulfate reducing gradually passes backward, and the sulfate conversion tends to be gentle and CODcr removal rate tends to decrease when the sulfate concentration increases and the HRT shortens. The sulfur ions in the front compartments quickly rise to a maximum value and the concentration appears on small fluctuations in the latter compartments. Alkalinity and VFA increase rapidly in front compartments, and then decrease slowly.
