<p>The apparatus transforms animal waste produced during husbandry activities into useful materials such as organic-based manure and/or fertilizer to thereby mitigate the pollution problems associated with such husbandry activities. A base part of the apparatus includes an endless conveyor having a filter in the form of an endless loop of flexible material. A liquid-collection receptacle is interposed between the upper and lower runs of the filter so as to collect liquid filtrate from the waste material. A first hopper is located beneath one end of the endless loop so as to collect the solid content of the waste conveyed along the upper run of the filter. A second hopper is provided to accommodate material to be added to the solid content of the waste. The materials are fed from the respective hoppers into a mixing chamber whereupon they are mixed by a mixer provided in the mixing chamber. The base part of the apparatus is connected to a closed system of treatment tanks via piping leading from the liquid-collection receptacle and from the mixing chamber. In the tank for treating the liquid content of the waste material, there is provided a filtration layer at the bottom of the tank, a motor-driven carriage, and stirring bars extending from the motor-driven carriage toward the filtration layer. A desired quantity of soil is added into the tank and the tank is closed. The liquid content of the waste is introduced into the tank and when the motor-driven carriage is actuated, the stirring bars are rotated and moved across the tank to mix the liquid content of the waste with the soil to thereby produce high quality fertilizer. The tank for treating the solid materials is substantially identical with the exception that no filtration layer is provided at the bottom of the tank. In this way, high quality organic-based manure is produced.</p> |
