Heavy metals in waste water use in the production process a large number of acids, alkalis, heavy metals in solution, toxic and hazardous chemicals, including cadmium, cyanide, chromic anhydride, emissions in the process waste water, waste gas and waste of polluting the environment and endanger human health,has become a heavily polluting industries.
Of heavy metals in the wastewater, the commonly used methods can not be decomposed destruction, but only to transfer the location of its existence and changes in its physical and chemical forms. : Processing by chemical reduction and precipitation of heavy metals in the waste water from the dissolved ionic state into insoluble compounds and precipitate down, transferred to the sludge from the water, and then by ion-exchange treatment, there is in the regeneration solution. Short of heavy metals in waste water treatment the formation of two products, one is basically off in addition to the processing of heavy metals in water, heavy metals concentrated product - sludge. The heavy metal concentration is less than the emission standards of treated water can be discharged in line with the best production of process water reuse. Of heavy metals in the concentrated product has a use value, try to recycle, there is no recovery value to be harmless treatment.
