懸浮填料生物反應(yīng)器石化廢水生物硝化研究

摘要: 采用自行研制的懸浮填料生物反應(yīng)器中試裝置對石油化工廢水進行處理.通過6、8、10和12 h四個不同水力停留時間的硝化過程取得了不同運行條件下的氨氮去除效果.結(jié)果表明,懸浮填料生物反應(yīng)器完全可以達到生物硝化的目的.當進水中BOD5和CODcr質(zhì)量濃度變化范圍在77.4~234.0 mg·L-1和245.5~695.7mg·L-1時,其平均去除率分別為90%和80%以上,平均出水質(zhì)量濃度分別小于15和90 mg·L-1.試驗期間進水氨氮質(zhì)量濃度在8.3~53.2 mg·L-1范圍內(nèi),四個工況條件下的平均去除率分別為55.5%、86.7%、91.1%和95.6%,平均出水質(zhì)量濃度分別為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   作者單位: 同濟大學  期 刊: 同濟大學學報(自然科學版)  ISTICEIPKU   Journal: JOURNAL OF TONGJI UNIVERSITY(NATURAL SCIENCE)  年,卷(期): 2001, 29(4)  分類號: X703  關(guān)鍵詞: 懸浮填料    生物反應(yīng)器    石化廢水    廢水處理    生物硝化
