摘要
制革污泥中含有大量的有机物、氮磷钾等多种营养成分,非常适合制作有机肥。以制革污泥为原料,通过添加猪粪、米糠、菜饼、沸石等各种不同成分,进行了好氧高温发酵试验。种子发芽率试验表明,堆肥腐熟度较好;盆栽试验结果显示,堆肥产品作为有机肥能够明显提高植物产量,同时作为叶面肥使用也有良好效果。
Tannery sludge contains large amounts of organics and nitrogen, phosphorus, potassium and other nutrients, which is suitable for organic fertilizer production. High temperature aerobic fermentation tests were carried out with tannery sludge as raw material, adding pig manure, rice bran, zeolite and other various components. Seed germination tests show a good compost maturi ty, and pot experiments show that compost as organic fertilizer could significantly increase plant yield, and also has good results as foliar fertilizer.
