摘　　要：采用厌氧序批式反应器 (ASBR)处理高浓度硫酸盐废水 ,取得了较好的效果 模拟废水和实际钛白粉废水的试验显示 ,硫酸根离子的去除率分别达到 92 .1% ,83.5 % COD SO42 -的比值对硫酸根离子去除率有较大影响 ,比值在 2～ 3时效果最佳 该试验工艺的一个特点是采用了气循环与水循环并用的方法 ,以防止硫化氢气体对硫酸盐还原菌 (SRB)的毒害 。The wastewater of high concentration sulfate was disposed by Anaerobic Sequencing Batch Reactor(ASBR), and good result was obtained. The test showed that the sulfate removing rates for wastewater and TiO 2 reach to 92.1% and 83.5% respectively. The specific value of COD/SO 4 2- has a great influence in removing sulfate in the wastewater, and the best effect is obtained for the value between 2 and 3. The characteristic of the experiment was that the gas circle and the water circle were both used so that to decrease the toxicity of H 2S gas to the bacteria and the wastewater was stired by this method as well.
