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/SO4^2-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不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,同时起搅拌作用。

关 键 词:ASBR  酸性钛白废水  技术研究  废水处理  厌氧序批式反应器  硫酸盐还原菌

Abstract: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.
Keywords:wastewater treatment  biological technology  anaerobic sequencing batch reactor  wastewater of TiO  2  sulfate  reducing bacteria
