| 摘 要： | 研究了生物滴滤塔净化含H2S与NH3臭气最佳的生态条件为:在温度为25 ℃、气体通气量为0.4 m3/h、营养盐喷淋量为8.0 L/h、入口H2S质量浓度712.80-948.80 mg/m3、入口NH3质量浓度422.20-795.40 mg/m3、pH值7.0-8.0之间的情况下,去除效率可达90%以上.生物滴滤塔在处理H2S和NH3混合气时,塔内pH值保持在6.5-8.5之间,此pH值对反应器中优势菌的生长繁殖不会造成太大影响,对处理效果影响不大,因此反应过程可不用对pH值进行调节,节约运行成本.

| Abstract: | Research on the optimal ecological conditions for microbial degradation of mixed odor of H2S and NH3 is conducted, including temperature at 25 %, the nutrient sprinkling rate at 8 L/h, aeration rate at 0.4 m^3/h with incoming H2S eonoentration at 712.80 - 948.80 mg/m^3 and NH3 at 422.20 - 795.40 mg/m^3, pH at 7.0 - 8.0 and the cleaning efficeney can reach above 90% under these conditions. When treating the mixed odor of H2S and NH3 in biotriekling filtering pond, it has little impact on the growing up of dominating bacteria and the cleaning efficiency with pH value at 6.5 - 8.5, so it is not necessary to regulate pH value in the reaction course and the eoat can be saved. |
