Metal ore beneficiation wastewater processing method

Abstract

The invention relates to a metal ore beneficiation wastewater processing method, which uses a bottom plate, a shell frame, a filter device and a discharge pipe. The shell frame is mounted in the middle of the upper end of the bottom plate, the filter device is mounted at the upper end in the shell frame, and the discharge pipe is mounted at the lower end of the right side of the shell frame. Solved are the problems that when a conventional facility is used to filter beneficiation wastewater, the water injection amount cannot be accurately adjusted; wastewater is generally accumulated on the upper surface of a filter screen; the pressure load of the filter screen surface is large; the water passing capability of the filter screen is influenced; meanwhile, the filter screen is easily damaged, and the service life of the filter screen is affected. The problems that when a conventional facility is used for filtering beneficiation wastewater, slag particles, settling particles and other impurities in the wastewater are usually easily accumulated on a filter screen, meshes of the filter screen are easily blocked by the impurities, and the beneficiation wastewater filtering effect is affected are solved.

Description

technical field [0001] The invention relates to the technical field of beneficiation wastewater processing, in particular to a method for processing metal ore beneficiation wastewater. Background technique [0002] The beneficiation wastewater of metal mine ores contains a large amount of harmful substances, which generally cannot be recycled directly. If the beneficiation wastewater is discharged into rivers, lakes and other waters, it will cause water acidification, destroy the growth environment of bacteria and microorganisms, and reduce the self-purification function of water bodies. , and the heavy metals in mineral processing wastewater are non-biodegradable and difficult to remove from the environment. Once inside the microorganisms or microbial communities, heavy metals remain in the organisms leading to bioaccumulation. [0003] At present, the existing mineral processing wastewater usually has the following defects when it is processed: 1. When the existing equipm...

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot accurately adjust the water injection volume when filtering the mineral processing wastewater, and the wastewater usually accumulates on the surface of the filter screen, resulting in a large pressure load on the screen surface and affecting the overshoot of the screen. At the same time, it is easy to cause damage to the screen and affect the service life of the screen. Moreover, when the existing equipment is used to filter the mineral processing wastewater, impurities such as slag particles and sedimentation particles in the wastewater are usually easy to accumulate on the filter screen. It makes it easy for impurities to block the mesh of the filter screen, affecting the filtration effect of mineral processing wastewater and other problems.
