Electrolytic dephosphorization equipment

Abstract

The invention discloses electrolytic dephosphorization equipment and in particular discloses electrolytic dephosphorization equipment with an aerating device, belonging to wastewater treatment technology and equipment. The electrolytic dephosphorization equipment is characterized in that a water inlet pipe is arranged on one side of the upper part of an electrolytic tank; a water outlet pipe is arranged on the lower part of the other side of the electrolytic tank; circular electrode plates installed on a rotating shaft are arranged above the electrolytic tank; one of the electrode plates is an aluminium plate and the other one is an iron plate; the electrode plates are connected with a direct-current power supply; and the aerating device is installed at the bottom of the electrolytic tank and is connected with a blower by a gas pipe. The electrolytic dephosphorization equipment is simple and reasonable to operate and achieves unattended operation, and compared with the traditional electrolytic dephosphorization equipment and chemical dephosphorization methods, which need manpower to dispense drugs and switch valves, the electrolytic dephosphorization equipment saves time and labor, improves the dephosphorization efficiency, reduces the operation cost and is more energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to wastewater treatment technology and equipment, in particular to electrolytic dephosphorization equipment with an aeration device. Background technique [0002] The electrolytic dephosphorization equipment uses an iron plate or an aluminum plate as an electrode, which is immersed in water and connected to a DC power supply. The anode electrolyzes under the action of the power supply to produce iron ions or aluminum ions. These ions can be combined with PO in sewage. 4 3- React to produce insoluble compounds, and then separate these insoluble compounds from sewage by solid-liquid separation; some iron ions or aluminum ions will interact with OH in sewage in different pH ranges - The reaction produces iron or aluminum hydroxyl compounds and precipitation, and PO in sewage 4 3- It will be adsorbed on the surface of the above substances, and the sediment and particles will be removed, so as to achieve the purpose of phosphorus re...
