An animal waste disposal system including a housing with an area for holding a bed of particulate litter, a scoop with a plurality of perforations for separating animal's waste from the particulate litter, and a drive mechanism for moving the scoop to remove animal's waste from the bed of particulate litter. The waste-removing operation is carried out by collecting a mixture of animal's waste and particulate litter in the interior of the scoop and moving the scoop in a raised position over the area for holding the bed of particulate litter to allow the collected particulate litter to sift through the perforations in the scoop while retaining animal's waste for disposal into a waste container. The bed of particulate litter may be arbitrarily defined by a plurality of contiguous sections, each of which can be cleaned or processed separately and independently. Two types of retractable partitions are provided to make the waste-removing mechanism inaccessible to the animal during its automatic operation.

An apparatus and method for treating and reusing the wastewater discharged from agricultural animal farms. The apparatus and method of the present invention is designed to be a zero discharge system in which no wastewater will be discharged or spray irrigated. The wastewater effluent is first passed through a mechanical screen were bulk solids are separated and partially de-watered. The screened effluent is then directed to a primary plastic-lined earthen lagoon where it undergoes aerobic digestion utilizing specially selected bacteria. After treatment in the primary lagoon, the wastewater effluent is used to wash the floors of the hog houses or undergoes a purification phase including solids separation / denitrification, filtration and sterilization. The solids separation / denitrification phase (clarification) preferably takes place in an anoxic environment in preferably above-ground tanks where suspended solids removal will occur as well as denitrification for nitrate reduction. The clarification process may be facilitated through use of polymer addition. The majority of solids will be sent to a plurality of drying beds for de-watering and subsequent removal.

Animal waste such as fecal material from swine, chicken, turkey, and cattle is converted into useful forms such as fertilizer, other types of soil builders, and even nutrient feed additives. Devices, systems, and methods are provided that allow economical conversion and in many instances, alleviate the production and release of undesirable gases such as sulfide and ammonia. In one embodiment, undesirable anaerobic and facultative anaerobic bacteria are killed at a greater rate than desirable soil compatible aerobic bacteria. The use of low temperature killing diminishes off gassing commonly associated with other techniques, and the use of gas trapping additives such as zeolites provides enhanced soil building qualities such as slow release of nitrogen and slow release of moisture to soil. The methods allow convenient adjustment of composition, allowing conversion of waste into tailored designer fertilizer suited for particular soils. Other embodiments provide other soil building qualities as well as nutrient qualities for feedstock used in animal husbandry such as aquaculture.
