| 摘 要： | 吸附法在含铬废水处理方面占据重要地位,其关键在于吸附材料的性能。天然吸附材料种类繁多,但大多数材料吸附能力弱、容量小、速度慢,需要进行改性处理。为了增加对改性技术的认识,对铬吸附材料的改性技术进行了系统分析和比较,明确了热改性、无机改性、有机改性和负载改性技术的研究进展与应用状况。

| Abstract: | Adsorption method has an important role in the treatment of chromium-containing wastewater,and treatment efficiency depends on the performance of adsorption materials.Because of small adsorption capacity and slow speed,most of raw adsorption materials should be modified.Modification technology and research progress and application situations of thermal modification,inorganic modification,organic modification and coat modification have been systematically analyzed and compared. |

| Keywords: | chromium-containing wastewater adsorption adsorption materials modified technology |
