| titleOfInvention | Manufacturing method of eco-friendly compost using livestock manure from which heavy metals are removed, and eco-compost manufactured therefrom |
| abstract | The present invention relates to a method for manufacturing environmentally friendly compost by removing heavy metals from livestock manure, and more specifically, (1) a first step of collecting and pretreating livestock manure and mixing with an aqueous solution of oxalic acid dihydrate in a heavy metal removal device; (2) a second step of separating the livestock manure sludge after removing the oxalic acid dihydrate aqueous solution containing copper and zinc from the mixture; (3) a third step of adding slaked lime to the separated livestock manure sludge to increase the pH; (4) a fourth step of adding the subsidiary materials to the livestock waste sludge to which the lime is added; (5) a fifth step of supplying a blowing air to the mixture of the fourth step in a stirring equipment for 12 hours a day and inverting once a day for 5 days to ferment for 25 days; And (6) relates to a method for producing environmentally friendly compost using livestock manure removed heavy metals, characterized in that it comprises a sixth step of blowing the air only for one week to ripen.n n n According to the present invention, it is possible to remove heavy metals from livestock manure using oxane dihydrate, to improve the treatment efficiency and utilization of livestock manure, and to prevent soil contamination by heavy metals. |
