摘要： The subject invention provides improved methods for processing livestock waste, namely, for solid-liquid separation of manure, utilizing microbe-based products. In preferred embodiments, microorganisms and/or microbial surfactants are utilized to improve solid-liquid separation of livestock manure in ways that enhance the value of manure-based fertilizers to farmers and reduces greenhouse gas and other polluting emissions resulting from manure storage.

摘要： A gearbox particularly useful for liquid manure pumps has a power input shaft that is coupled through a gearset to an impeller of the pump. The rotation axis of the impeller is angled in a range of 55-75° with respect to the rotation axis of the power input shaft. Such an arrangement provides both the necessary power and the correct pump orientation for a trailer-mounted pump to efficiently and effectively pump liquid manure from the bottom of a liquid manure lagoon having long sloped sides.

摘要： An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.

摘要： This invention refers to a method for preparing a chemical digester characterized by using organic and inorganic elements used for multiple purposes such as an accelerator in the decomposition of organic matter, as a water flocculant, as an organic soil fertilizer and as a means to eliminate the concentration of flies and other inserts in organic matter to decompose. The method comprises heating water in a reactor at a temperature of 38° C., adding a polysaccharide, an anti-thickener and an antifoam. The method then comprises the addition of two organic acids, one of them previously mixed in a second reactor and, finally, an inorganic acid until the mixture is homogenized. Optionally the method comprises the packaging of the mixture and the treatment of organic matter.

摘要： A system for comprehensive treatment of cultivation pollution in a scalable pig farm includes a source separation pigsty, a pigsty flushing water treatment system, a solid-liquid separation system, a solid high-temperature aerobic fermentation system, a liquid high-temperature aerobic fermentation system, an odor and flue gas treatment system, a boiler system and a test and control system. The source separation pigsty is designed into a pigsty that separates feces and urine from rainwater, pigsty flushing water and residual drinking water. The sludge pump pumps the feces and urine to the solid-liquid separation device. Solids separated by the solid-liquid separation device are conveyed to the solid high-temperature aerobic fermentation system, and liquid separated by the solid-liquid separation device is conveyed to the liquid high-temperature aerobic fermentation system. The boiler system includes a boiler, a circulating pump, a hot water pipeline and a water return pipeline.

摘要： To produce fertilizer, a system and method concentrates manure slurry in a mechanical vapor recompression evaporator (“MVR”) having a heat exchanger. The MVR receives the manure slurry within a first side to evaporate ammonia laden-water vapor from the slurry, leaving a nutrient concentrate. A compressor raises the evaporated ammonia-laden water vapor to a higher energy state. Within a second side of the heat exchanger, the compressed water vapor conveys heat to the slurry. Ammonia-laden water condenses in the second side at a process temperature to be conveyed to an ammonia stripping tower where the ammonia-laden water is dispersed into ammonia-laden water droplets. In the tower, a flow of air is directed across a surface of the ammonia-laden water droplets, the process temperature having been selected to promote the escape of ammonia gas from the ammonia-laden water droplets, the flow of air provided to entrain ammonia gas in the flow.
