废水中硫化物、硝酸盐和氨氮生物同步去除及其机理
Simultaneous biological removal of nitrate, sulfide and ammonia from wastewater and its mechanism
摘要
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.关键词
