Recovery method for waste kerosene from copper electro winning workshop and recovery system thereof

The invention discloses a copper deposition workshop waste kerosene recovery method and recovery system thereof belonging to the copper deposition workshop waste kerosene recovery technique field. The recovery method comprises firstly adding sulphuric acid for reextraction, and then standing for separation and drawing off aqueous phase, then further adsorbing impurities by adding clay, finally filtrating the solution by plate filter and obtaining qualified filtrate as recovered waste kerosene. The recovery system comprises two outlet ends arranged in an agitated tank with one outlet end connecting to an electrolytic barren solution tank and the other outlet end connecting to an oil pump and the oil pump outlet connecting to the plate filter. Two branches are arranged at a filtrate port of the plate filter, wherein one branch connects to an organic phase storage tank, and the other branch connects to a platform PVC tank. An outlet of the platform PVC tank connects to an inlet of the agitated tank and a filter
