【摘要】 为了确证脱酚焦化废水亚硝化型硝化及以焦化废水中的氨酚为电子供体实现亚硝酸盐的反硝化的可行性 ,以模拟 SBR法的好氧与厌氧过程。对脱酚后的焦化废水实现了亚硝化型硝化 ,产生的亚硝酸盐浓度达到 1 1 7.6mg/ L。以未脱酚的焦化废水中的酚、氨为电子供体 ,实现了亚硝酸盐的反硝化更多还原

【Abstract】 In order to ascertain the feasibility of nitrification via nitrite using phenol-degrading coking wastewater and denitrification using ammonium or phenol in coking wastewater as electron donor, the experiment is divided into two steps: simulating the aerobic process and anaerobic process of SBR method. Nitrification via nitrite is realized using phenol-degrading coking wastewater, and the nitrite concentration reaches 117.6mg/L Denitrification via nitrite is also realized using ammonium or phenol in coking wastewater as electron donors.更多还原
