摘要
概述了硫酸盐型厌氧氨氧化、反硝化脱氮除硫和微生物燃料电池脱氮除硫3种生物同步脱氮除硫工艺的发展概况及工艺条件。该技术能将废水中的氮硫元素同时去除,避免了氨氮、硫酸盐分别处理时过程不稳定、去除效率不高等不足,并且在脱硫的同时能够回收硫单质,实现资源回收,不产生二次污染,具有广阔的应用前景。展望了3种工艺的在实际研究中的应用前景,认为微生物燃料电池同步脱氮除硫技术将去除污染物及产生电能有机结合,具有很大研究潜力及价值;应加强脱硫反硝化技术碳氮硫同时去除的优化条件和一体化设备的设计及运行调控的研究;加强硫酸盐型厌氧氨氧化反应功能菌种的筛选、探讨反应的机理,探索适合硫酸盐型厌氧氨氧化反应的合理启动运行方式。
This article summarized current development and process conditions on sulfate anaerobic ammonia oxidation, denitrification and desulfurization, denitrifying and sulfide-removal in microbial fuel cell. Above three technologies could simultaneous removal nitrogen and sulfur, and avoid shortcomings such as unstable reactive process and low removal rate resulting from traditional removal process. This technology could recycle elemental sulfur, realize recourse recovery and no secondary pollution, and has broad application prospects. This review also discussed application perspective of these three technologies. The simultaneous nitrogen and sulfur removal technology of microbial fuel cell combined pollutant removal with electricity generation, which has tremendous development potential and value. The research of optimum conditions of simultaneous carbon, nitrogen and sulfur removal by denitrifieation and desulfurization technology, the design and operation control of integrated equipment should be enhanced. The screening of sulfate anaerobic ammonia oxidation strains, discussion of reaction mechanism, exploration of reasonable start-up mode should be enhanced also.
