| 摘 要： | 采用浸没式SBR膜生物反应器处理焦化废中的NH3-N,对运行效果的考察表明:系统硝化效果主要受温度、pH、溶解氧、冲击负荷等因素的影响。膜的截留作用能使硝化菌在反应器内富集,提高系统短期的硝化能力,同时,也使微生物代谢产物或其它大分子物质积累,抑制了硝酸盐细菌的活性,导致NO2-积累。

| Abstract: | A submerged membrane Sequencing Batch Bioreactor was used to treat coke wastewater. The results show that: the system was deeply affected by temperature, pH value of the effluent, DO of the mixed liquid, sudden raise of influent NH3-N concentration. As the result of membrane separation, the ammonia oxidizing bacteria was all kept in the reactor and the nitrifying ability of the system was enhanced. Membrane separation results in the accumulation of the bacterial metabolic products, which inhibit the activities of nitrite oxidizing bacteria and make the nitrite to accumulate. |
