摘要
对复合式厌氧反应器处理含硫酸盐有机废水的工艺特性、动态特征进行了研究．试验结果表明在一定的有机负荷下,当进水SO42-浓度从1g／L提高到1．5g／L时,COD去除率约保持在67％,系统的稳定性增加;当继续提高硫酸盐浓度到2．5g／L时,反应体系发生深度恶化。此外,MPB受抑制的程度主要由H2S决定,SRB受抑制的程度主要由TS因素所决定。
The process and dynamic characteristics of treating organic wastewater containing sulfate with complex anaerobic reactor are studied. The result shows that the stability of the system, the sulfate reduction rate and COD removal increase with the concentration of sulfate of inflow from 1g/L to 1.5g/L. However, the system will become seriously worse if the concentration of sulfate reaches 2.5g/L. In addition, the hydrogen sulfide decides the degree of MPB restraint and TS decides the degree of SRB restraint.
