| 中文摘要 |
| 利用廉价天然锰矿物作催化剂,在常温常压下进行催化氧化法去除硫化物的实验研究.在所研究的浓度100-400mg/L范围内,使用的反应器为10L.控制气量0.1m3/h,曝气时间4h,催化剂加量100-150mg/L,pH值9-10时,硫化物去除率达94%-98%.和未加催化剂相比减少了曝气量和曝气时间,可以使能耗降低30%,处理成本降低20%. |
| 英文摘要 |
| A cheep natural mineral manganese was used as a catalyst to catalytically oxidate sulfur-bearing wastewater at the ambient temperature and pressure.When the wastewater has a sulfur concetra-tion of 100-400mg/L,and is treated in a 101.reactor at pH 9-10, with an air flow of 0.1m3/h and a catalyst dose of 100-150mg/L for 4 hours, the removal of sulfur from wastewaster reaches 94%-98%.As compared with the similar process without catalyst,the present process has a reduced air volume and time for aeration, about 30% reduction in energy consumption, and about 20% reduction in treatment cost.The results show that Using this King of cheep natural mineral manganese as a catalyst to catalytically oxidate sulfur-bearing wastewater is an effective method. |
