A METHOD AND APPARATUS FOR PROCESSING WATER TREATMENT RESIDUALS
A method for processing water treatment residuals, or other amorphous aluminium oxide or aluminium hydroxide rich waste residuals, for use in the manufacture of hydraulic binders, comprising heating the residuals to remove water and oxidize organic material contained therein, comprising controlling the temperature of the residuals during heating such that they are heated to a temperature no higher than 800 DEG C, more preferably no higher than 650 DEG C, to ensure that aluminium compounds in the WTR, in particular aluminium oxide and aluminium hydroxide, remain in an amorphous state. The method may comprise controlling the temperature of the water treatment residuals such that they are heated to a temperature between 350 DEG C and 650 DEG C, more preferably between 400 DEG C and 500 DEG C.
一种用于处理水处理残余物或其它富含非晶态氧化铝或氢氧化铝的废弃残余物以便用在水硬粘合剂制造中的方法，包括加热该残余物以除去水和氧化其中所含的有机材料，包括在加热过程中控制残余物温度，使得它们被加热到不高于800℃，更优选不高于650℃的温度，以保证WTR中的铝化合物，尤其是氧化铝和氢氧化铝保持在非晶态。该方法可以包括控制该水处理残余物的温度，使得它们被加热到在350℃与650℃之间，更优选在400℃与500℃之间的温度。
