<p>PURPOSE: A treatment method of high-concentration organic wastewater is provided, which can provide suitable aerobic fermentation condition for the husk bed thus maximizing fermentation heat generation to evaporate water content in organic matter rapidly. The optimum fermentation condition is produced by sufficient agitation and air supply to the husk. CONSTITUTION: The system comprises an aerobic fermentation bed(10), a moving device(20), an agitating device(30), a blower(50) and a compressor(60). In the fermentation bed(10), rice husk(S) is filled and organic wastewater of high concentration is sprayed thereon. The moving device(20) having agitating device(30) that consists of an agitation shaft(33), an impeller(34) and a shaft end(43), reciprocally moving along a guide rail(21), agitates the husk. This agitation makes the husk move upward and left and right side, forming sufficient pore space in the husk and supplying sufficient air to the husk, so that the heat generated from the aerobic decomposition of the husk makes the moisture evaporate to produce organic fertilizer of good quality.</p> |
