The invention discloses a heating network circulating water treatment system and method with electrochemical softening coupled with electric flocculation. The system includes a pressurization unit, an electrochemical softening unit, an electric flocculation unit, a clarification unit and a sludge treatment unit, wherein the pressurization unit, The electrochemical softening unit, the electric flocculation unit and the clarification unit are arranged in sequence along the water flow direction of the circulating water in the heating network; the electric flocculation unit includes a first pole plate, a second pole plate and a first control device; the first pole plate and the second pole plate alternate A first gap is set between the first pole plate and the adjacent second pole plate; the first pole plate and the second pole plate are electrically connected with the first control device, and the first control device can make the first pole plate And the second plate is inverted. The first electrode plate and the second electrode plate are soluble electrodes. The system can realize the softening of the circulating water in the heating network, the combined removal of suspended particles and impurities of metal corrosion products, and the system design is reasonable, easy to use, and not easy to produce secondary pollution. |
