摘　　要：铬是人体必需的一种微量元素,但六价铬是水体污染的一种主要重金属污染物,盐产品中氯化钠含量分析主要以铬酸钾(100g/L)为指示剂,大量含铬废液未经处理直接排放将对环境水体造成严重污染。本文通过探究亚铁氰根检测废液处理含铬废液处理工艺,最大限度的降低了废水中六价铬和总铬的含量,做到了低浓度排放,最大化减少环境污染。Chromium is an essential trace element for human body,but hexavalent chromium is a major heavy metal pollutant in water pollution.Potassium chromate(100g/L)is the main indicator for sodium chloride content analysis in salt products.A large amount of waste liquid containing chromium will cause serious pollution to environmental water without treatment.In this paper,by exploring the treatment process of waste liquid containing chromium from ferrous cyanide root detection,the content of hexavalent chromium and total chromium in wastewater is reduced to the maximum,and the low concentration discharge is achieved,and the environmental pollution is reduced to the maximum.
