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: Provided are a perovskite catalyst, and a preparation method and use thereof in electromagnetic degradation of an organic waste. In the preparation method of the perovskite catalyst, the perovskite catalyst is prepared by co-precipitation. A precursor with a higher purity is prepared by limiting types, concentrations, and addition ratios of reaction raw materials as well as controlling a temperature and a pH value of the precipitation reaction, and provides a desirable basis for the preparation of a subsequent catalyst. The precursor is subjected to aging and calcination to obtain the perovskite catalyst.
