摘要
通过文章的叙述,能了解水体中砷及其化合物的存在形态和毒性;沉淀法、电凝聚法的原理与适用场合;矿物吸附、活性炭吸附、生物吸附、工业废弃物吸附在含砷废水处理中的应用及其处理效果;膜处理技术在含砷废水处理中的应用,并提出了膜处理技术和联合技术的应用是水中砷处理今后的发展方向。
The existence forms and toxicity of arsenic and its compounds were analyzed in the water and wastewater body. The principle and application situation of precipitation as well as electro - coagulation method were discussed. The application and the removal efficiency of mineral adsorption, activated carbon adsorption, biosorption and industrial waste adsorption in arsenic wastewater treatment were studied and the application of membrane technology was also discussed. The membrane technology and integrated technique would be widely used in the future that was put forward.
