【摘要】 炸药废水的处理研究一直是令人关注的课题，它有着重要的理论和实际意义。混合炸药JH-16生产废水虽然可生化性较好，但生产废水中含有难降解物质黑索今，且其营养物质缺乏，碱度偏低，给生化处理提出了较大的难度要求。 本研究对混合炸药JH-16生产废水进行实验室间歇厌氧发酵实验，试验结果表明厌氧生物法对黑索今的去除率可达到94％，COD去除率可达到87％。根据这一结果，提出采用UASB—生物接触氧化结合的处理方法使其达标排放。 以牛粪为接种物对UASB进行初次启动的研究结果表明，牛粪中甲烷菌活跃、增值较快、容易获得可作为UASB反应器的接种物从而解决UASB接种物源不足问题。在本工程中，UASB容积负荷增加平稳；黑索今处理效果良好，在厌氧阶段可达到平均88％的去除率，出水黑索今浓度达到国家黑索今工业水污染物二级排放标准；生物接触氧化工艺对厌氧出水进行后续处理效果良好，其出水水质全面达到国家一级污水排放标准。更多还原

【Abstract】 Much attention was paid to treatment of explosive wastewater at all times. It is important to research the treatment theoretically and practically. Although wastewater in the process of producing hybrid dynamite JH-1 6 has preferable biochemical treatability, it contains such hardly biodegraded material as RDX, lacks nutrimental material and alkalinity, and thus results in difficulty of treatment. In the laboratory, experiment of Batch anaerobic digestion of wastewater in the process of producing hybrid dynamite JH-16 was processed, the experimental results show degradation rate of hexahydro- 1,3 ,5-trinitro- 1,3,5- triazine(RDX) and COD by anaerobic treatment comes up to 94% and 87% respectively. According to the results, UASB and Bio-contact Oxidation was brought forward to discharge wastewater regularly. UASB is seeded using Cattle manure and processes First Start-up for this reactor. The results indicate that methanogenisis of cattle manure is active, its increment is rapid, seeded material of UASB is easily obtained, and problem of lack of seeded material resource of UASB is resolved; Volume Loading Rate increases smoothly. Effect of treatment of RDX is good, and reaches average degradation rate of 88% in anaerobic period. Concentration of effluent RDX achieves national secondary degree standard of industrial wastewater discharge of RDX. Bio-contact oxidation process plays an effective role in following treatment of effluent in UASB, and quality of effluent achieves national first degree standard of wastewater discharge.更多还原
