Remediation of acid mine drainage from abandoned coal mines by crustacean biomass
摘要
Abstract
Acid mine drainage(AMD)pollution from abandoned sulfur-rich coal mines represents a major challenge for building an ecological civilization in China.Completing a green and low-carbon measure for treating AMD using low-cost and sustainable environmental materials has become a major scientific and technological demand.Chitin Biomass is rich in calcium carbonate,chitin and protein,with a wide range of sources and low use rates.Using shrimp and crab shells to prepare remediation materials in treating AMD reflects"Treating the wastes with wastes".Based on the review of the research status of shrimp and crab shells as a remediation material for treating AMD,it was identified that shrimp shells could be used not only as an alkaline material to neutralize the acidity of AMD,but also as an organic to promote the metabolic activities of microorganisms.In addition,the chitin and the gained chitosan extracted from shrimp shells were rich in groups such as hydroxyl and amino groups which could form coordination complexes with heavy metal ions.Thus,shrimp shells were promising multifunctional materials for treating AMD in abandoned coal mines.The green chitin extraction technology from shrimp shells and its restoration application under mining conditions will be the frontier and focus of future research.关键词
