wastewater that is highly saline but has a low content of heavy metals such as Cd, Cr, and Pb. The stabilized and raw residues have been subject to a range of leaching tests: the batch leaching test, the pH-static leaching test, the availability test, and the column test. These tests showed that the stabilized residues have remarkably improved leaching properties, especially with respect to Pb but also
已在半工业规模上针对三种类型的APC残留物证明了一种稳定的方法,用于从城市固体废物焚化(MSWI)排放的空气污染控制(APC)残留物,包括将残留物与水和FeSO4混合,半干式(SD)APC残留物,粉煤灰(FA)以及来自湿法烟气清洁系统的FA与污泥(FAS)混合。该过程分批处理,残留量为165-175 kg。它产生的废水含盐量高,但重金属如Cd,Cr和Pb的含量低。稳定的残渣和未经处理的残留物已经过一系列浸出测试:分批浸出测试,pH静态浸出测试,可用性测试和色谱柱测试。这些测试表明,稳定的残渣具有显着改善的浸出特性,尤其是对于Pb而言,对于Cd而言,铜和锌 铅的释放减少了250-36,000倍。
