Abstract

The invention relates to treatment equipment for wastewater, and in particular relates to the chemical treatment equipment for rare earth extraction wastewater. The technical problem to be solved is that the invention provides the chemical treatment equipment which can continuously treat the rare earth radioactive wastewater without interruption and has a fast treatment speed for the rare earth extraction wastewater. The technical solution of the invention is as follows: the chemical treatment equipment for the rare earth extraction wastewater comprises a hollow cylinder, a sewage pipe, a medicine sprinkling device and the like; and the sewage pipe is installed on the upper left side of the hollow cylinder, and the medicine sprinkling device for adding medicines for first treatment of thewastewater is installed at the left side of the top of the hollow cylinder. According to the equipment provided by the invention, the hollow cylinder is divided into two spaces, the wastewater can besimultaneously treated in the two spaces, so that the wastewater can be continuously treated without interruption, and the treatment speed of the wastewater can be accelerated; and a flow speed control device can control a water flow speed of the wastewater to change a distance that an L-shaped plate moves to the right, so that a speed of adding the medicines can be controlled, and the treatment effect of the sewage is better.

Description

technical field [0001] The invention relates to a wastewater treatment device, in particular to a rare earth extraction wastewater chemical treatment device. Background technique [0002] Rare earths are known as "industrial vitamins". Now it has become an extremely important strategic resource. Rare earth element oxides refer to oxides of 15 lanthanide elements with atomic numbers from 57 to 71 in the periodic table of elements, and oxides of scandium and yttrium, a total of 17 elements whose chemical properties are similar to lanthanide elements. During the production process of rare earths, a large amount of radioactive wastewater will be produced. Because the radioactive wastewater contains different harmful substances, the wastewater needs to be treated multiple times before it can be discharged to meet the standard. [0003] When dealing with the radioactive wastewater discharged by rare earth, separate equipment is used to treat the radioactive wastewater. When the ...
