Electrochemical water treatment device and method convenient to clean

The invention is applicable to the technical field of electrochemical water treatment, and provides an electrochemical water treatment device and method convenient to clean. An electrolysis main body, a first cleaning assembly and a second cleaning assembly are arranged in the reaction tank; the electrolysis main body comprises cathode plates and anode plates, the cathode plates and the anode plates are distributed at intervals, and the cathode plates and the anode plates are electrically connected with a cathode and an anode of a direct-current power supply respectively; through cooperation of the first cleaning assembly and the second cleaning assembly, scale removal is carried out on the inner wall of the reaction tank and the electrolysis main body, scale residues are avoided, the cleanliness and hygienic standard of equipment are improved, the electrochemical reaction efficiency is improved, the water treatment efficiency is further improved, and the water treatment cost is reduced. Meanwhile, the scale
