Arsenic Removal by Sulfidation in Wastewater Treatment
Arsenic is ubiquitous in nature.Arsenic compounds have strong toxicity,and entering the environment will cause great harm to people's production and life.In this paper,the arsenic removal process of neutralization sulfidation,flotation sulfidation,heavy metal capture agent sulfidation and microbial sulfidation was introduced,and the characteristics of arsenic removal by sulfidation were analyzed.The current research status of arsenic removal technology by sulfidation at home and abroad was reviewed,and the development trend and application prospect of arsenic treatment were analyzed and prospected.
