NOVELTY - The utility model claims a graphene thin film electrode plate electro-catalysis device, comprising a box body, the top end of the box body is provided with a primary filtering device; the inner part of the box body is a cavity one, a chamber two and a chamber three, the chamber one and the chamber two are separated by a clapboard one; the chamber two and the chamber three are separated by a clapboard two; the clapboard one and the clapboard two are provided with a water flow control device. The utility model can use the primary filtering device to effectively filter the large particle impurities in the sewage, avoid it directly enter into the catalytic device, and through the three chambers set, can carry out multiple catalytic treatment to the sewage, so that the impurity in the sewage can be effectively absorbed, the catalytic efficiency is further improved, the whole sewage treatment effect is obviously improved.
