摘　　要：以人工配制的含硫酸盐有机废水为原水,对厌氧折流板反应器(ABR)处理硫酸盐有机废水的启动过程进行了研究。实验结果表明,采用低COD和SO42-负荷进水方式,经3个阶段成功启动了反应器,实现了产酸相、硫酸盐还原相及产甲烷相的分离:第1、2、3隔室为水解产酸及硫酸盐还原相,第4、5隔室为产甲烷与硫单质生成相。在启动过程中,pH的变化滞后于VFA变化,因此及时对各隔室VFA浓度进行监测能反映反应器的运行状况。With the artificial prepared organic wastewater containing sulphate as the raw water, the start-up process with anaerobic baffled reactor （ABR） treating organic wastewater containing sulphate was investigated. The results showed that the ABR reactor was started up successfully under low COD and SO4^2- concentrations through three stages. The acidogenic phase, the sulphate-reduced phase, and methanogenic phase were separated in the reactor： the 1st, 2nd and 3rd phases were acidogenic and sulphate-reduced phases, then the 4th and 5th phases were methanogenic and sulfur-producing phases. The diversigation of enfluent pH was lag to that of enfluent VFA, so the situation of reactor could be reported in time through monitoring the effluent VFA concentrations.
