| 摘 要： | 在HRT为12 h,温度为30℃±2℃,进水p H为7.5,进水硫化物、硝酸盐氮和氨氮浓度分别为50~90mg S·L-1,22~35 mg N·L-1和22~35 mg N·L-1条件下,能够实现氨氮、硝酸盐氮和硫化物3类污染物的同步去除,去除率分别达到97.3%、92.8%和99%以上,而且去除的硫化物主要以单质硫形式存在,单质硫理论转化率达89%以上。间歇实验结果表明,S2-的存在能够促进NO-3-N、NH+4-N的同步去除。研究结果为含硫含氮废水的生物处理技术的发展提供了新思路。

| Abstract: | Simultaneous removal of nitrate, sulfide and ammonia could be realized at HRT of 12 h, temperature of 30℃±2℃ and influent pH of 7.5. The removal rates were up to 95%, 90% and 99% for ammonia, nitrate and sulfide at influence concentrations of 22-35 mg N·L-1, 22-35 mg N·L-1 and 50-90 mg S·L-1, respectively. Most of sulfide removed was converted to elemental sulfur (S0) and the conversion rate was as high as 89%. Batch experiment results indicated that presence of sulfide could enhance simultaneous removal of nitrate and ammonia. The results of this study provided an innovative idea for the development of sulfide- and nitrogenous contaminants- laden wastewater treatment technology. |
