生物法废气脱硝研究

, 1999
将城市生活污水处理厂活性污泥中的反硝化细菌培养挂膜到填料塔中，进行从模拟废气中脱除ＮＯｘ的效果性能实验研究．该生物膜填料塔能有效地脱除废气中的ＮＯｘ，ＮＯ２的去除率可达９９％以上，ＮＯ的去除率可达９０％左右．该法最适宜的温度为３０～４５℃，进口ＮＯ浓度（５０～５００ｍｇ／ｍ３）对其去除率几乎没有影响，随着废气流量的增加 ...

焦化废水还原浸出软锰矿动力学

, 2017
以焦化废水为还原剂,在硫酸介质中利用收缩芯模型研究焦化废水加压直接还原浸出软锰矿的动力学,考察搅拌速度、反应温度、软锰矿粒径、硫酸浓度和焦化废水CODcr浓度对锰浸出速率的影响。结果表明:锰浸出率随反应温度、硫酸浓度、焦化废水CODcr浓度的增加和软锰矿粒径的减小而增大。在393 K~423 K间,焦化废水还原浸出软锰矿受固膜扩散控制,表观活化能为15.2 kJ/mol,硫酸和焦化废水CODcr浓度的表观响应级数分别为1.21和0.98。机理分析表明 ...
