<p>PURPOSE:To cause efficient aeration fermentation by circulating thick organic waste solution through combination of one suction pump and an ejector. CONSTITUTION:A suction pump 4 is connected to a fermentation tank 2 to suck the waste solution such as urine or excreta in the tank and lead the same to an ejector through a discharge pipe. It is then spouted into the fermentation tank together with air from said ejector 7, whereby it is forcefully aerated and stirred to undergo aerobic fermentation. In this way, the organic liquid fertilizer which is harmless to vegetables and contains effective fertilizer components may be produced at inexpensive costs and inexpensive charges.</p> |
