Abstract

The invention relates to the field of water treatment, in particular to a chlorinated organic matter degrading and dechlorinating method. The method includes: selecting copper powder and iron powder as raw materials for degrading and dechlorinating according to features of chlorinated organic matter; mixing and grinding the copper powder and the iron powder of a set proportion to obtain a copper-iron alloy material; pickling the copper-iron alloy material; using pure water to wash and dry the copper-iron alloy material after being pickled; mixing the copper-iron alloy material after being washed and dried with an organochlorine solution containing chlorinated organic matter for reduction dechlorinating reaction. Two degrading and dechlorinating mechanisms exist when the degrading and dechlorinating material is adopted, so that better dechlorinating effect can be realized, and industrial production needs are met.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a method for degradation and dechlorination of chlorinated organic matter. Background technique [0002] Chlorinated organic compounds are important chemical raw materials, intermediates and organic solvents, widely used in chemical, pharmaceutical, pesticide, leather and other industries. Such compounds mainly include chlorinated aliphatic hydrocarbons, chlorinated aromatic hydrocarbons and their derivatives. Chlorinated organic compounds are highly toxic and difficult to biodegrade. There have been studies on the treatment of chlorinated organics by chemical reduction. [0003] The chemical reduction method to treat chlorinated organic compounds is to use reducing agents to remove chlorine substituents in pollutant molecules in a targeted manner, so as to reduce the biological toxicity of chlorinated organic compounds and improve their biodegradability. Commonly used reducing ...
