Abstract: Provided is a method for catalytic degradation of an organic waste. The method for catalytic degradation of an organic waste provided by the disclosure includes: step (1) under a condition of a closed micro-oxygen environment, mixing the organic waste with a magnetic thermally conductive catalyst to obtain a mixture, and subjecting the mixture to catalytic degradation to obtain a catalytically degraded gas, a catalytically degraded suspended particulate matter, and a catalytically degraded solid; and step (2) purifying the catalytically degraded gas and the catalytically degraded suspended particulate matter obtained in step (1), then discharging, and subjecting the catalytically degraded solid obtained in step (1) to magnetic separation to obtain an ash and a recovered magnetic thermally conductive catalyst; wherein the catalytic degradation is conducted at a temperature of 200° C. to 250° C. for 15 h to 24 h.

Abstract: A magnetization pyrolysis device for organic waste and a using method thereof are provided. During the magnetization pyrolysis of organic waste, the device uses perovskite as a catalyst, and includes a crushing reaction chamber combining a crushing zone with a reaction zone; a crushing mechanism for crushing waste; and a heating mechanism for heating the waste, the crushing mechanism and the heating mechanism are arranged in the crushing reaction chamber. In accordance with the present disclosure, the crushing zone is combined with the reaction zone, which significantly reduces the treatment space and cost. In-situ degradation of household waste can be achieved by the device without leaving the village, and the daily cleaning of everyday rural waste can be effectively achieved.

Abstract: A waste treatment device and a waste treatment method using the device are provided, and relates to the technical field. The waste treatment device includes a first treatment chamber for preliminary treatment of waste, a second treatment chamber for further treatment of the waste, a feed port for feeding the waste, a crushing component for crushing the waste, a discharge port for discharging waste residues, and light wave degradation components for releasing light waves to degrade the waste. The first treatment chamber is in communication with the second treatment chamber. A feed port is formed at the first treatment chamber. The crushing component is arranged inside the first treatment chamber. The discharge port is formed at the second treatment chamber. The light wave degradation components are arranged inside the first treatment chamber and the second treatment chamber.

Abstract: A device for wholly treating urban and rural mixed household refuse at low temperature on site is provided. The device includes a vibration sieving and crushing system, a magnetic separator, conveyor belts, a magnetic pulse mineralization reactor and a tail gas purifying device. By using the device, urban and rural mixed household refuse is continuously fed; the mixed household refuse is sieved by the vibrating sieve according to viscosity, weight and size; nonferrous metal is sieved through a magnetic field; and organic substances are conveyed to the magnetic pulse mineralization mixed household refuse treatment device for terminal treatment. So, efficient reduction and harmlessness of the organic substances in the mixed household refuse are realized, and the pollution of organic wastes on the environment is effectively eliminated.
