PROBLEM TO BE SOLVED: To provide a system for recovery of an electrodeposition paint which can reduce loss of the paint in a multistage recovery and washing process for a membrane filtration filtrate in electrodeposition coating, by efficiently increasing a washing liquid in the final stage, and which is actualized by utilizing existing equipment. SOLUTION: The system for recovery of an electrodeposition paint supplies the membrane filtration filtrate of electrodeposition bath liquid into the final stage washing tank of a membrane filtration filtrate multistage recovery and washing process, and is characterized in that the multistage recovery and washing process for a membrane filtration filtrate includes at least one dip type washing tank, the filtrate obtained by carrying out the membrane-filtration of the liquid in the at least one dip type washing tank is supplied into the final stage washing tank, and the concentrated liquid is supplied into an electrodeposition bath and/or a washing tank at a stage before the dip type washing tank in which the liquid in the washing tank is membrane-filtrated.
