摘要
基于调控环境因子来探寻KOH改性生物炭在最适环境条件下对As污染土壤的修复效果。结果表明:KOH改性生物炭修复土壤中总砷的最适pH=7.5;适含水率为20%~25%;最适温度为20℃~30℃;最适有机质含量为16 g/kg^28 g/kg;最适全氮含量为0.85 g/kg^1.25 g/kg。
Based on the adjustment of environmental factors,the remediation effect of KOH modified biochar on As-contaminated soil under the most suitable environmental conditions was explored.The results show that the optimal pH of KOH-modified biochar to repair total arsenic in soil is 7.5.The optimal moisture content is 20%~25%.The optimal temperature is 20~30℃.The optimal organic matter content is 16g/kg^28 g/kg.The suitable total nitrogen content is 0.85~1.25 g/kg.
