摘要
化工行业产生的含无机氯废液在处理过程中可能出现设备氯腐蚀、产生二噁英等大气污染物、废酸或废盐污染地表水与土壤等问题。含无机氯废液可先经预处理将无机氯与有机物分离后,再进行分质处理。介绍了含无机氯废液预处理技术的原理、特点与研究进展,提出了含无机氯废液预处理技术发展与应用前景。
The equipment may be corroded by chlorion,there may be dioxin and other atmospheric pollutants,and waste acid or salt may pollute the water and soil,when the waste liquid containing inorganic chloride generated from chemical industry were treated.The waste liquid containing inorganic chloride could be pretreated and separated to be inorganic chloride and organic materials before being treated separately.This paper introduced the principle,characteristics and research progress of pretreatment technology of inorganic chlorine-containing waste liquid,and the development and application prospect of the pretreatment technology were put forward.
