Description
Technical Field

Background
A certain company adopts zinc-containing fly ash as a raw material to produce heavy metal elements such as copper, zinc and the like, and the production process mainly comprises leaching, microfiltration, extraction, washing, back extraction and electrodeposition processes. The copper-zinc wastewater mainly comes from a washing process, and the wastewater contains copper, zinc, cadmium, lead, calcium, chloride ions and the like.
Ultrafiltration is a membrane separation technique using pressure difference as a driving force, the average pore diameter is between that of a reverse osmosis membrane and a microporous filter membrane, particles such as bacteria, viruses, colloids and macromolecules in water are intercepted, and water and low molecular weight solutes permeate the membrane. The water inlet requirement of reverse osmosis can be fully guaranteed by the SDI index and the particles, the pollution degree of the reverse osmosis membrane is greatly reduced, the cleaning period of the reverse osmosis membrane is prolonged, the service life of the reverse osmosis membrane is prolonged, and therefore the overall operation cost is reduced.
The reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics and is made by simulating a biological semipermeable membrane, and is a core component of a reverse osmosis technology. The principle of reverse osmosis is that under the action of the osmotic pressure higher than that of the solution, other substances are separated from water based on the fact that the substances cannot permeate a semipermeable membrane. The reverse osmosis membrane has a very small membrane pore size, and thus can effectively remove dissolved salts, colloids, microorganisms, organic substances, and the like in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, simple and convenient operation and the like.
The electrodialysis system is a scientific water treatment technology which is mainly characterized in that under the action of a direct current electric field, dielectric medium ions in water passing through a partition plate move directionally, and water quality is purified by utilizing the selective permeation effect of an exchange membrane on the ions. Between a pair of electrodes of an electrodialyzer, a plurality of groups of negative membranes, positive membranes and separators (A, B) are alternately arranged to form a dense chamber and a dilute chamber (i.e., positive ions can permeate through the positive membranes, and negative ions can permeate through the negative membranes). The positive ions in the water migrate to the negative electrode and penetrate through the positive membrane to be intercepted by the negative membrane in the thick chamber, and the negative ions in the water migrate to the negative membrane in the positive electrode direction and are intercepted by the positive membrane in the thick chamber, so that the ion number in the water passing through the fresh chamber is gradually reduced to form fresh water, and the concentration of dielectric ions in the water in the thick chamber is continuously increased due to the continuous surge of the positive ions and the negative ions in the thick chamber to form thick water, thereby achieving the purposes of desalination, purification, concentration or refinement.
