The utility model discloses a device for leaching manganese, iron and aluminum in microwave enhanced manganese oxide slag, which comprises a rotating device, a microwave feed inlet, a microwave cavity, a temperature control system and a leaching container, the rotating device is connected with the microwave cavity through a bearing, the microwave feed inlet is connected with the microwave cavity through a microwave feed-in deformer and a waveguide tube, and the temperature control system is connected with the leaching container. A sensor and a controller of the temperature control system are connected with the microwave cavity and the direct current motor; and the leaching container is fixed on a container jacket in the cavity. Through cooperation of microwaves and rotary stirring, energy is focused through the deformer, infrared temperature control and corrosion resistance design are combined, efficient leaching is achieved, the reaction time is shortened, the leaching rate is increased, and the device is energy-saving, environment-friendly, easy and convenient to operate and suitable for resource utilization of various solid wastes.

The application discloses a treatment system and a treatment method for resource utilization of waste salt, and utilizes saturated brine to clean the waste salt, so that a large amount of organic matters and impurity ions in the waste salt enter into the salt washing water; the waste salt is separated into the salt washing water and dry salt through solid-liquid separation; the separated salt washing water with high organic matter content enters into a catalytic wet oxidation system; and the separated dry salt with low organic matter content enters into a membrane catalytic ozone oxidation unit for treatment after being salted. The application couples the catalytic wet oxidation technology and the membrane catalytic ozone oxidation technology, greatly improves the waste salt treatment efficiency, and solves the problems that, when the catalytic wet oxidation technology is used alone to treat the waste salt, the waste salt needs to be salted into a large amount of waste brine; and when the membrane catalytic oxidation technology is used alone to treat the waste salt, a large amount of water needs to be added to dilute the organic matters, thereby causing the low waste salt treatment efficiency.
