【摘要】 研究了凤眼莲对水溶液中马拉硫磷降解作用的效果及凤眼莲修复马拉硫磷污染水体的主要机理.结果表明,10~11g凤眼莲可将250mL的10mg/L马拉硫磷的降解速度提高160%.其修复机理主要是凤眼莲吸收马拉硫磷后在体内进一步降解,贡献率可达56%,微生物降解的贡献率占9%.更多还原

【Abstract】 The main mechanism of the effects of water hyacinth (Eichhornia crassipes Solms) on the degradation ofmalathion in aqueous solution and its remediating the malathion polluted water was studied. The results showed that the degradation rate of 10mg/L malathion in 250mL was enhanced by 1.6-fold with 10~11g of water hyacinth. Its mainremediation mechanism is that the water hyacinth absorbing and degradating takes a role of 56% and microorganisms take a contribution rate 9%.更多还原
