摘要

在HRT为12 h

温度为30℃±2℃

进水pH为7.5

进水硫化物、硝酸盐氮和氨氮浓度分别为50～90 mg 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NO3--N、NH4+-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.
