Abstract
An electrochemical nitrogen and phosphorus removal device includes a three-dimensional electro-catalytic oxidation unit reactor, a three-dimensional electro-biological coupling unit reactor, a light filter material filter unit reactor and a three-dimensional electro-flocculation phosphorus removal unit reactor; a water outlet pipe of the light filter material filter unit reactor is connected to both a main water outlet pipe and a water inlet pipe of the three-dimensional electro-flocculation phosphorus removal unit reactor; and a water outlet pipe of the three-dimensional electro-flocculation phosphorus removal unit reactor is connected to a water inlet pipe of the light filter material filter unit reactor through a reflux pump and a check valve. The device can achieve the purpose of efficient sewage treatment by the combined action of electrochemical flocculation, electro-catalytic oxidation and electro-active microorganisms.
