Integrated device for treating mine water with diatomaceous earth

Abstract

The invention relates to an integrated device for treating mine water with diatomaceous earth, and belongs to the technical field of mine water treatment. The integrated device comprises a water inletpipe, a dosing pipe, a pipeline mixer, a water inlet branch pipe, a reaction chamber, a guide cylinder, a separation chamber, a filtering region, a backwasher and a water outlet pipe, wherein the pipeline mixer is respectively connected with the water inlet pipe, the dosing pipe and the water inlet branch pipe; the water outlet pipe is arranged at an upper part of the separation chamber; the guide cylinder is arranged in the separation chamber; the reaction chamber is arranged in the guide cylinder; the filtering region is arranged at a periphery of the guide cylinder in the separation chamber; and the backwasher is arranged above the filtering region in the separation chamber. The integrated device provided by the invention integrates various functions of coagulation, sedimentation, filtration and adsorption, has advantages of simple process, small occupied area and convenient operation and management, and effectively reduces operating costs while ensuring stable water quality.

Description

technical field [0001] The invention relates to the technical field of mine water treatment, in particular to an integrated device for treating mine water by using diatomite. Background technique [0002] Mine water, as a precious water resource, has good economic, environmental and social benefits if it is treated and recycled. For the treatment of mine water, the coagulation-sedimentation-filtration process is usually used in the industry to achieve standard discharge. If reuse is to be achieved, advanced treatment must be carried out through adsorption, disinfection and other processes. Mine water with high salt content requires Desalination treatment. The traditional method of coagulation + sedimentation + filtration can effectively remove suspended solids, but it involves many structures, occupies a large area, the energy consumption of the coagulation unit is high, the filter needs to be backwashed, and the filter material is easy to block and harden.
