Abstract
Disclosed are a production method for compost using stock farm wastewater and a compost production system. The compost production method comprises: a step in which stock farm wastewater is anaerobically digested; a step in which solids are separated from the anaerobically digested stock farm wastewater; a step in which ammonia is collected from the solid-free effluent; a step in which multi-phase membrane separation is performed to concentrate nutrient salts, humic acid and micro-inorganic matters in the effluent from which ammonia has been collected; and a step in which the resulting products, having been separated, collected and concentrated respectively by the solid separation step, the ammonia collecting step and the multi-phase membrane separation step, are dried. It is a benefit of the invention that safe, high-quality dry compost can be produced by collecting as much useful humic acid and nutrient salts as possible from the stock farm wastewater. Moreover, the dry compost thus produced can be stored and sprayed easily, and when introduced into a farmland the solids are decomposed and the nutrient salts are eluted, so the pollution of rivers and groundwater due to a temporary spill can be avoided.
