摘　　要：采用中草药残渣与锰泥混合加入饲料发酵剂发酵除去锰泥中锰。结果表明,中草药残渣与锰渣的比例为1:1时,发酵13 d后,锰的去除率达到99.0%。与传统的化学、物理和生物修复除锰相比,该方法整个发酵过程都是在室内自然条件下进行,处理成本低,简便易行,去除锰的效果令人满意。且处理后的锰渣具有绿色有机肥的潜力。A microbial fermentation method, assisted by feed yeast, was adopted to remove manganese in its slag mixed with Chinese herbs residue in an appropriate ratio. Results showed that with the addition of 0.1 g per 1 kg slag, ratio of Chinese herbal residue to slag 1：1 and fermentation for 13 days, the removal rate of manganese reached 99.0%. In comparison with traditional chemical, physical and biological rehabilitation methods, this method, which was conducted indoors, is cost effective and simple, with satisfactory effect of manganese removal. In addition, the waste after removing manganese is full of humus materials and has the potential to become organic manure.
