Abstract： |
This invention relates to an electrode ionization method that reclaims heavy metal waste water and its equipment, which reasonably combines ion exchange and electric dialysis. Its characteristic is: fill unitary strong acid positive resin at top of waste water purification room, intercept heavy metal ion, migrate to thick water room, and get its thick water; at bottom of waste water purification room, fill mixture of strong acid positive resin and strong base negative resin, intercept reliquus natrium salt with inferior part resin, migrate its ion in thick water room, and get purified water, meanwhile reclaim and use thick water prepared from waste water and purified water obtained by processing. It can achieve waste water zero release, implement waste water harmless and recycling. This equipment has advantages of simple structure, convenient to use, and low cost. |
