The Research Of Making Use Of Cement To Handle Dangerous Waste

The year of dangerous discard produces quantity to reach near ten million ton, and present year by year up-trend. BE high because of the heavy metals chemical element content imply in the dangerous discard and at physics, the chemical effect descend easy fuse in water or with spirit the condition form existence, often can cause the human body immunity ability descend, the density is low can make human body chronic poisoned, the density is high can produce the deadly poison function, would to large people crowd of life constitute severity threat. Therefore, the dangerous discard has to be harmless to turn a processing.This thesis adoption solid discard immerses a toxicity of measurement method, combine the cement raw material craft function to experiment, cement the physical function experiments to mix to match the method that the thing function experiment with common concrete, passing to discard to the Ni the residue, magnesium chrome brick, the city garbage power station flew these dangerous discards of ash,remnants to carry on harmless turn treatment of research.At harmless turn to handle of in the meantime, make it become two resourceses, comprehensive exploitation. Pass a great deal of experiment result, get a development to make use of the Ni discards a residue, magnesium chrome disabled brick, the city garbage thing should notice of the prior condition of the item and usage:The Ni residue does original material to produce cement, can the single disabled usage, can't double the disabled handle. And can produce a high-quality cement familiar anticipate, each age' s expecting strength can raise 3.5% above, it whets easily and burns all medium etc. of the craft function easily, doing the raw material usage, from immersing a toxicity consideration amount of disabled can't more than 8.0%, mainly is control the heavy metals Cr ion in the cement to immerse a density;Can prolong the cement coagulation time while doing the hybrid material usage, raise the fluxion degree of the cement, along with the disabled quantity increment, the severity of secrete water, strength lower.
