摘　　要：针对煤化工废水处理难点和技术发展需求,从典型反应器和新型生物强化技术2个方面探讨了厌氧生物处理技术的现状和关键问题。分析认为,厌氧生物处理工艺可强化难降解有机物、氮素污染物和硫酸盐的去除,提高煤化工废水可生化性;常规厌氧反应器仍存在启动时间长、生物量有限等问题,需要通过生物固定化、生物强化、反应器模型优化、流体数值模拟等手段加以优化;厌氧生物强化技术开发还应充分考虑有机物、氨氮、硫酸盐等多种污染物的协同去除,妥善处理好不同种群微生物之间的关系。According to the treatment difficulties and technology development requirements of coal chemical wastewater, the situation and key problems of anaerobic biological treatment technology were discussed from two aspects, including typical reactors and new biological enhancement technologies. The analysis suggested that the biodegradability and removal effects of refractory organics, nitrogen pollutants, sulfates can be enhanced with anaerobic biological treatment technology. The problems of long start-up time and limited biomass about regular anaerobic biological treatment technology can be solved with bio-immobilization, biofortification, reactor optimization and fluid numerical simulation. The development of anaerobic biological treatment technology should be fully considered about the synergetic removals of various pollutants such as organics, ammonia nitrogen and sulfates. Moreover, the relationship of different microbial population should be properly handled.
