Beschreibung
Zusammenfassung:	The invention relates to an organic fertilizer prepared from sludge, which comprises the following components in percentage by weight: 60-70% of sludge, 27-35% of organic waste and 3-5% of biomass fermenting enzyme. The sludge is pure sludge in which heavy metals and substances that are harmful to plant growth are removed. The organic waste comprises 5% of plastic waste, 8% of waste rubber, 5% of fiber fabric, 12% of waste paper, 15% of rice bran, 14% of coconut shell, 6% of leaf, 10% of bark, 3% of flower and grass, 7% of kitchen peel, 5% of cake pulp, 5% of vinasse and 5% of bagasse. The organic fertilizer can effectively improve the soil structure, has longer effective time, can lower the fertilizer use cost, and enhances the environmental contribution rate.
