摘　　要：利用将厌氧处理、好氧硝化和同步脱硫反硝化(SDD)相结合的工艺,来实现废水中高浓度的SO42-、NH3-N以及有机污染物的同步去除。研究了不同因素对厌氧处理过程的总产气量和H2S产气量的影响,研究了将含H2S气体注入SDD反应器对SDD过程的影响,研究了利用自产气体对厌氧反应器吹脱对厌氧过程的影响。结果表明,将厌氧反应器产生的含H2S的气体通入SDD反应器,可以提高反硝化的效率,同时也减少了对H2S气体回收的成本。利用自产气体对厌氧反应器进行吹脱,可以有效地降低厌氧反应器中H2S的含量,提高系统的处理效率。The high concentration sulfate, ammonia and organics containing wastewater was treated by the combination of anaerobic reactor, aerobic nitrification reactor and simultaneous de-sulfurization and de-nitrification （SDD） reactor, and sulfate, ammonia and organics in the wastewater would be removed simultaneously. The effect of different aspects on the total gas production and HzS gas production of the anaerobic reactor, the effect of stripping the gas with H2S into the SDD reactor on SDD process and the effect of stripping the anaerobic reactor on the anaerobic process were investigated. Results showed that, the NO^- removal rate would be increased and the cost of H2S recycle would be decreased after stripping the gas into SDD reactor. Stripping the anaerobic reactor would decrease the amount of H2S in anaerobic reactor and make the system more efficiently.
