摘要
采用硫酸盐还原－生物脱除硫化物－甲烷化的方法，考察了酸相反应器的运行效果，以及系统的操作条件和运行情况等。结果表明：①以拉西瓷环为填料的厌氧滤地作为酸相反应器，容积负荷可达５ｋｇ／（ｍ３·ｄ），去除率为８０％；②在脱硫化物反应器中，硫化物去除率大于９０％，其中９５％的硫化物转化为Ｓ０；③甲烷相反应器ＣＯＤ容积负荷可达１５．８ｋｇ／（ｍ３·ｄ），ＣＯＤ去除率为８３．３％。整体工艺ＣＯＤ去除率为８７．６％，去除率为９９．４％－１００％。
two-phase anaerobic digestion process has been developed for treating high strength organic wastewater containing a high level Of Sulphate.The system comprises: ac anaerobic filter packed with Rasching rings which was used as an acidogenie reactor wilh a volumetric loading of 5 kg SO-/(m3. d) and a SO- removal efficiency of 80% ;② a desulphiding reactor with a sulphide removal rate of more than 90%, of which more than 95% was converted to S0;③ a methanogenic reactor with a COD volumetric loading rate Of 15. 8 kg COD/(m3. d) and a COD removal efficiency of 83. 3%. The whole system has an overall COD removal efficiency of 87. 6% and a SO removal efficiency of 99. 4%-100%.
