Process for preparing organic fertilizer by biological mud and grass refuse of papermaking plant

Abstract

一种利用造纸厂生化污泥和草渣制备有机肥的方法,属于有机肥技术领域。草渣3~6份,生化污泥3~5份,粉煤灰1~2份,鸡粪1~2份,生物发酵菌剂0.005~0.01份,使混合物的水分含量在55%~60%,各原料按重量份置入发酵池中,当物料的温度升高到50℃时,进行翻抛,当物料温度变化不明显时,继续发酵7~12天,将发酵好的物料晾干备用。向发酵好的物料中加入化肥氮磷钾和微量元素或者复合解磷和解钾菌发酵原液,可得普通有机肥、有机无机复混肥或生物有机肥。本发明的方法能够变废为宝,生产方法简单,减少肥料用量,防止肥料对环境的污染。
The invention relates to a method of using biochemistry sludge and grass of paper mill to make organic fertilizer that belongs to organic fertilizer technology field. It contains 3-6 portions of grass, 3-5 portions of biochemistry sludge, 1-2 portions of fly ash, 1-2 portions of chicken manure, 0.005-0.01 portion of bio-fermentation agent, water content is 55%-60%. Putting the material into fermenting tank, after the temperature reaching to 50 degree centigrade, turning over, keeping fermenting for 7-12 days when the temperature altering not so obvious, drying the material, adding chemical fertilizer and microelement, normal organic fertilizer and organic inorganic mixture fertilizer would be gained. The invention is simple technology, and would stop the pollution to the environment from fertilizer.
