Abstract

The invention belongs to the technical field of water treatment, and particularly relates to a device for removing iron in acid-containing copper sulfate. The device comprises a positive electrode plate and a negative electrode plate, wherein an anode porous plate and a cathode porous plate are respectively placed on two sides of an iron removal chamber; a perfluorosulfonic acid positive membrane, a positive electrode plate, an electrode chamber water distribution net, a water distribution plate and a locking device are sequentially arranged outside the anode porous plate; a bipolar membrane, a negative electrode plate, an electrode chamber water distribution net, a water distribution plate and a locking device are sequentially arranged outside the cathode porous plate; the locking device fixes the whole device through the water distribution plates on the two outer sides and is in a cuboid shape. The method has the advantages that the membrane separation method is high in recovery rate, thorough in separation, simple to operate, high in automation degree and good in working environment, economic benefits can be brought, better environmental benefits are achieved, the use amount of alkali is saved while acid is recovered, the sludge output is greatly reduced, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a device for removing iron from acid-containing copper sulfate. [0002] technical background [0003] Copper sulfate is both a fertilizer and a commonly used fungicide. Bordeaux mixture, copper soap, and copper ammonium preparations are prepared from copper sulfate, quicklime, soap, and ammonium bicarbonate. Mainly used as textile mordant, agricultural insecticide, water fungicide, preservative, also used in tanning, copper electroplating, ore dressing, etc. In the chemical industry, it is used to manufacture other copper salts such as cuprous cyanide, cuprous chloride, cuprous oxide and other products. In the dye industry, it is used as a copper complexing agent for the production of copper-containing monoazo dyes such as reactive brilliant blue, reactive violet, and phthalocyanine blue. It is also a catalyst for organic synthesis, perfume and dye intermed...
