Abstract
Noxious odors and water pollution commonly associated with the raising of hogs, cattle or poultry under confined conditions are eliminated by replacing the conventional waste lagoon and waste spreading fields with a wastewater treatment plant. The treatment plant extracts manure from the wastewater, then dries and burns the manure along with collected waste gases. The liquid waste portion is filtered, deodorized and then recirculated to the growing buildings as flushwater.
Claims20
A method of processing animal wastes produced in a confined animal growing area, said method comprising:
- separating an animal waste stream into a first component consisting essentially of wet waste solids and a second component consisting essentially of liquids;
- dewatering the first component to form dewatered waste solids;
- burning the dewatered waste solids;
- evaporating at least a portion of the second component in an in-ground solar evaporator basin;
- and
- draining liquid from the in-ground solar evaporator basin to a reservoir during periods of rain to limit the amount of rainwater that mixes with the second component.
A method of processing animal wastes produced in a confined animal growing area, said method comprising:
- separating an animal waste stream into a first component consisting essentially of liquids and a second component consisting essentially of waste solids having a water content;
- transferring at least a portion of the first component to an in-ground solar evaporator basin such that the first component forms an air-liquid interface having a first surface area;
- evaporating at least a portion of the contents of the in-ground solar evaporator basin;
- draining the contents of the in-ground solar evaporator basin to a reservoir such that the contents of the reservoir form an air-liquid interface having a second surface area smaller than the first surface area;
- and
- refilling the in-ground solar evaporator basin using the contents of the reservoir.

- transferring at least a portion of the first component to an evaporator basin such that the first component forms an air-liquid interface having a first surface area;
- evaporating at least a portion of the contents of the evaporator basin;
- maintaining a predetermined liquid level in the evaporator basin as the contents of the basin evaporate;
- draining the contents of the evaporator basin to a reservoir such that the contents of the reservoir form an air-liquid interface having a second surface area smaller than the first surface area;
- and
- refilling the evaporator basin using the contents of the reservoir.
