新型生物氧化反应器的技术开发与应用研究

开发了新型生物氧化反应器并阐述了该反应器的工作原理及特点。研究了生物氧化反应器在炼油含酚废水、炼油碱渣及污水回用方面的应用。研究结果表明：在适宜的工艺条件下处理炼油含酚废水可使挥发酚的去除率〉90％，COD的去除率〉60％，出水酚浓度〈20mg／L，COD〈200mg／L；在处理炼油碱渣时采用二段生物氧化反应器可使COD、硫化物、石油类和酚类污染物的去除率分别达到75_3％、98．9％、92_3％和85．0％；在污水回用系统中，当进水指标符合GB8978—1996污水综合排放标准一级标准时，经生物氧化反应器处理后，出水指标可达到COD≤55mg／L。Oil≤2mg／L，NH3-N≤5mg／L，悬浮物（ssl≤6mg／L，为后续处理单元提供了稳定合格的进水．实现环境效益与经济效益的“双赢”。新型生物氧化反应器是一种高负荷、高效率、投资省、运行费用低且应用广的石化废水处理设备，具有广阔的工业应用前景。

Study on the Technology Development and Application of Biological Oxidation Reactor

A novel biological oxidation reactor(BOR) was development and the principle and characteristic was expounded.Study of the BOR applied on treatment of phenol-containing wastewater and alkaline sewage and wastewater recycle.The result showed that the degradation of volatile phenol and COD can be accomplished 90 %,60 %;the average removal percentages of COD,sulfide,oil pollutants and volatile phenol were 75.3 %,98.9 %,92.3 % and 85.0 % by using the novel two stage BOR;when the inflowing concentrations of BOR was reachable to class I of the national standard of integrated wastewater discharge(GB8978-1996),the effluent water treated by the BOR would contain COD,oil,NH3-N and Suspension solid are respectively less than 55 mg/L,2 mg/L,5 mg/L and 6 mg/L,which meets the influent requirement of follow-up treating equipment unit.Then realizing the two parties win in both economic effect and environment effect.The BOR was a kind of high loading rate,high treatment efficiency,economize on investment,low cost treatment process and application extensively.The prospects of the BOR are brightening.
