Progress in Bioremediation of Heavy Metal Contamination:Based on Microbially-induced Carbonate Precipitation Technology
摘要
Abstract
To effectively address the escalating heavy metal contamination in water bodies and soils,microbial-induced carbonate precipitation(MICP)technology,based on biomineralization,has recently garnered significant attention for remediating heavy metal pollution.Compared to conventional removal methods,MICP aims to induce calcium carbonate precipitation through microbial activity,offering cost-effectiveness and robust stability.This approach not only immobilizes heavy metals but also enhances the quality of contaminated matrices,demonstrating promising application prospects.This paper reviews recent advances in MICP and its applications in environmental engineering,encompassing mineral precipitation mechanisms,metabolic pathways,influencing factors,and progress in heavy metal remediation.Furthermore,it discusses the potential for large-scale implementation and three suggestions are put forward.Firstly,the internal and external factors of MICP process should be optimized to determine the optimal process conditions for microbial growth and mineral formation;the second is to further improve the treatment method of NH4+produced in the urea hydrolysis process of MICP to reduce the negative impact on the environment;the third is to optimize the process and automation steps to reduce the cost of MICP technology and realize the large-scale application of MICP.The research is expected to provide theoretical insights to advance MICP technology in environmental restoration and biomaterial synthesis.关键词
