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.

The invention relates to biological compositions comprising yeast cells that can be added to animal feed which upon ingestion by an animal can reduce the odor of manure produced by the animal. The invention also relates to methods for manufacturing the biological compositions, and methods of using the biological compositions as animal feed additives.

Novel methods and apparatuses are disclosed for the treatment of wastewater to reduce, often associated, offensive odors. Irrigation of oxygenated liquid on top of a permeable cover effectively creates an aerobic treatment zone at the top of the lagoon whereby odorous gases being produced anaerobically below the cover are metabolized within this zone before being released to the atmosphere. This same system also serves to increase evaporation from the overall waste handling system therefore substantially reducing or eliminating the need for land application of treated wastewater.

It's simple, cheap and has less consumption.

The invention relates to a method for preparing an organic fertilizer by using plant residues as a raw material. The method comprises the following steps: crushing the raw material to below 20mm, stirring and mixing the broken material with animal wastes or an inorganic fertilizer; controlling the C/N ratio of the mixed materials to be (15-35) to 1 and the pH to be 6-9; adding water, so that the moisture content in the mixed materials in the step (2) is 55-70wt%; adding a first composite microbial agent to ferment; after once fermentation, raising the temperature of windrows to above 50 DEG C; and spraying a water-dispersed second composite microbial agent to ferment for the second time. With plant residues heap corruption (composting) as a biological process for succession of a microbial community, through inoculation of exogenous complex microbial agents, efficient decomposition on agricultural wastes is facilitated; different composite microbial agents are respectively added at different composting stages; and a small amount of additives (animal wastes, urea, ammonium nitrate and the like) are added, so that the composting speed is increased, and the quality of the product organic fertilizer is really improved.

The present invention discloses an animal waste bag dispenser and disposal unit comprising a mounting bracket, a container for holding bags, having a bucket and lid, and a receptacle. The container and receptacle are attached to the mounting bracket by nuts and bolts which extend through apertures positioned along the length of the mounting bracket.
