Sewage treatment device for neodymium iron boron waste processing and treatment method

Abstract

The invention discloses a sewage treatment device and method for neodymium iron boron waste processing, and belongs to the field of sewage treatment for neodymium iron boron waste processing. A sewage treatment device for neodymium iron boron waste processing comprises a waste liquid treatment box, a solid-liquid separation box is fixedly installed on the top face of the waste liquid treatment box, rotating rods are rotationally connected to the two sides of the solid-liquid separation box correspondingly, and a fixing ring is fixedly connected between the adjacent ends of the two rotating rods; a sliding plate is slidably connected into the fixing ring. By arranging a mounting ring, a compression box and a pressing plate, the device not only can filter out waste materials in sewage, but also can extrude the waste materials, so that the sewage content in the subsequently discharged waste materials is greatly reduced, a water purifying agent of the device is accurately matched with the sewage, the water purifying agent cannot be wasted, and the water purifying effect is improved. The situation that purification is not thorough is avoided, time and labor are saved, a water purifying agent does not need to be manually and frequently added, and purified clean water is automatically discharged.

Description

technical field [0001] The invention relates to the technical field of sewage treatment for iron-boron waste processing, in particular to a sewage treatment device and a treatment method for Nd-Fe-B waste processing. Background technique [0002] NdFeB is simply a kind of magnet. Unlike the magnets we usually see, it is called "Magnetic King" because of its excellent magnetic properties. NdFeB contains a large amount of rare earth elements neodymium, and Iron and boron are hard and brittle. In the NdFeB production process, the water after washing the waste is purified by the sewage treatment device and discharged. The specific treatment operation is to put water purifying agent in the NdFeB sewage. [0003] However, the effect of the existing treatment methods is not obvious, because the NdFeB wastewater does not contain some water-soluble chemical elements, and some water-insoluble wastes generated during the NdFeB production process need additional filtration. In addition...
