Research Progress on Membrane Separation Technology for Removing Nickel Ions from Wastewater
Membrane separation technology has many advantages such as high efficiency,energy con-servation,and environmental protection.It conforms to the national"carbon peaking and carbon neu-trality goals"and"rural revitalization"policies,and has broad development space and application prospects.In the 21st century,countries around the world have prioritized the development of mem-brane separation technology as a high-tech,which has led to a new era of comprehensive development of membrane separation technology.This paper reviews the research on the removal of nickel ions from wastewater using traditional wastewater treatment technologies,including microfiltration,ultrafil-tration,nanofiltration,reverse osmosis,electrodialysis,and new organic-inorganic hybrid membranes.The advantages and disadvantages of various wastewater treatment methods are analyzed and com-pared.In response to the corresponding issues,relevant insights were proposed and prospects were made.
