摘要
铬革渣提取蛋白质和铬盐后的残渣,可以加工成有机肥,经在一品红、花叶假连翘和富贵竹三种花卉上与四种市售花肥比较,试用结果表明是一种高效和长效有机肥.从而使铬革渣全部被转化成有用之物,使整个处理过程实现零排放.
This paper presents a part of the process which was de veloped for reclamation of protein and by-products frpm chrome leather shavings. After protein and cjrome(Ⅲ) are extracted from leather scraps, the remainder is neutralized with quick lime, and then processed into granu-lated fertilizer. The results of tests showed that the organic fertilizer is available for flowers because of its long-term and high effectiveness.
