PURPOSE: Solid composting and fertilizer for water are provided to separate floating substances in highly concentrated livestock waste water without having inorganic phosphate or heavy metal by a solid-liquid separation method for producing high quality organic fertilizer. CONSTITUTION: A solid-liquid separation method of high concentration livestock waste water is performed by inputting sulfuric acid, hydrochloric acid and amino acid into the high concentration livestock waste water and by controlling pH 6.5-7. Active carbon powder or raw lime powder is input into the waste water and is adsorbed floating substances, nitrogen, phosphate or heavy metal. Oxidizing agents like PAC, aluminum oxide sulfate are input and aggregated by using a polymer aggregator after controlling pH 6.0-6.5. Floating substances are floated by using pressurizing floating tank. The solid-liquid separation method separates solid after passing through a screen. The solid-liquid separated colloidal solid is input to an aerobic fermenting system like ventilating fermenting tank, stirring-type fermenting tank or circular fermenting tank by mixing and stirring fly ash and waste wood for controlling brine rate, ventilation and coal quality rate proper to the aerobic fermentation. |
