摘要
目前许多废水不仅含有高浓度的氨氮,而且含有高浓度的硫酸盐,给废水治理带来难度。对同步脱硫反硝化工艺和硫酸盐型厌氧氨氧化工艺的研究进展进行了综述。同步脱硫反硝化工艺和硫酸盐型厌氧氨氧化工艺能同时脱氮和除硫,不仅无H2S排放,而且还具有节约碳源、污泥产量小和实现单质硫回收的优点。其中硫酸盐型厌氧氨氧化工艺无需曝气和有机物,具有更高的技术和经济优势,将是未来生物脱氮除硫技术的新方向。
Nowadays, there is a great deal of wastewater containing high-concentration ammonia nitrogen and sul- phate pollutants,which brings difficulties to wastewater treatment. The research progress in simultaneous desulphuri- zation denitrifieation process and sulfate anaerobic ammonia oxidation process are summarized. The two processes can remove ammonia and sulphate simultaneously. The advantages of these two processes are no H2S emission,low carbon resource, and low sludge yield and achieve elemental sulfur recovery. The sulfate anaerobic ammonia oxida- tion process does not need aeration and organic matter, having higher technical and economic advantages. It will be the future direction of biological denitrifieation and desulphurization.
