摘要： The instant invention relates to a process and plant for the transformation of dangerous wastes containing chromium six as contaminant into non dangerous wastes that can be stored without special care and will be degraded in the environment without time limit. The process basically consists of milling, extracting chromium six in liquid phase and under controlled conditions of stirring, time and temperature, proceeding then, through reduction, to transform the chromium six in chromium three and then precipitating as chromium trioxide, through gasification. The solid resulting from the transformation process can be used as raw material for the manufacturing of firebricks or eventually for the manufacturing of bricks used in the building industry through a process not included in the instant description.

摘要翻译： 本发明涉及将含有六价铬的危险废物作为污染物转化成非危险废物的方法和装置，其可以在没有特别小心的情况下储存并在环境中没有时间限制地降解。 该工艺主要由碾磨，六液相萃取，搅拌条件，时间和温度等条件进行研磨，然后通过还原，转化为铬三价铬，然后通过气化三氧化铬沉淀。 转化过程产生的固体可以用作制造耐火砖的原材料，或最终用于制造建筑工业中使用的砖块，通过本手册中未包括的方法。
