| 中文摘要 |
| 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,SO42-容积负荷可达5kg/(m3·d),SO42- 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%,SO42- 去除率为99.4%—100%。 |
| 英文摘要 |
| A two-phase anaerobic digestion process has been developed for treating high strength organic wastewater containing a high level of sulphate.The system comprises:① anaerobic filter packed with Rasching rings which was used as an acidogenie reactor wilh a volumetric loading of 5 kg SO42-/(m3·d) and a SO42- 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 SO42- removal efficiency of 99.4%—100%. |
