摘要： 采用自行研制的悬浮填料生物反应器中试装置对石油化工废水进行处理.通过6、8、10和12 h四个不同水力停留时间的硝化过程取得了不同运行条件下的氨氮去除效果.结果表明，悬浮填料生物反应器完全可以达到生物硝化的.目的.当进水中BOD5和CODcr质量浓度变化范围在77.4～234.0 mg·L-1和245.5～695.7mg·L-1时，其平均去除率分别为90％和80％以上，平均出水质量浓度分别小于15和90 mg·L-1.试验期间进水氨氮质量浓度在8.3～53.2 mg·L-1范围内，四个工况条件下的平均去除率分别为55.5％、86.7％、91.1％和95.6％，平均出水质量浓度分别为9.43、3.10、1.71和0.79mg·L-1. Abstract： A novel pilot scale suspended carrier biological reactor (SCBR) has been developed to study biological treatment for wastewater from petrochemical industry in the SCBR, at The Wastewater Treatment Plant of Shanghai Petrochemical Company. The HRTs of 6h, 8h, 10h and 12h was investigated to test the nitrification process to find out what level of ammonia nitrogen removal that could be obtained under different operation conditions. The study showed that the SCBR was suitable for nitrification purposes. When the influent concentrations of BOD5 and CODcr varied in a range of 77.4～234.0 mg· L- 1 and 245.5～695.7 mg· L- 1,the average removal efficiencies were 90 % and 80 %, and the average effluent concentrations were less than 15mg· L-1 and 90mg· L-1 for BOD5 and CODcr, respectively. During the test period the ammonia nitrogen concentrations varied from 8.3 to 53.2 mg· L- 1, the corresponding average removal efficiencies were 55.5 %,86.7%, 91.1% and 95.6 %, and average effluent concentrations were 9.43 mg· L- 1, 3.1 mg· L- 1, 1.71mg·L-1,and 0.79 mg·L-1, respectively at HRTs of 6h, 8h, 10h and 12h. 作 者： 夏四清 高廷耀 周增炎 XIA Si-qing GAO Ting-yao ZHOU Zeng-yan 作者单位： 同济大学 期 刊： 同济大学学报(自然科学版) ISTICEIPKU Journal： JOURNAL OF TONGJI UNIVERSITY(NATURAL SCIENCE) 年，卷(期)： 2001, 29(4) 分类号： X703 关键词： 悬浮填料 生物反应器 石化废水 废水处理 生物硝化【悬浮填料生物反应器石化废水生物硝化研究】相关文章：
