Abstract

The invention discloses a rotating cage net type filler electroflocculation reactor, which comprises an electroflocculation reaction tank, a water inlet pipe, a water outlet pipe, a floc discharge pipe, a water inlet retaining wall, a rotating cage mesh type filler electrode, and activated carbon particle dosing Inverters, UV lamps, variable frequency motors and controllers. The iron-based filler or aluminum-based filler coated with nano-titanium dioxide photocatalyst undergoes a photoelectrochemical synergistic reaction under the irradiation of an ultraviolet lamp and an electric field, so that the difficult-to-decompose and difficult-to-remove organic matter in the wastewater is converted into a flocculated substance through a photocatalytic chemical reaction. pollutants and accumulate on the filler surface. For the wastewater treated by this reactor, the removal rate of chemical oxygen demand reaches 95.1%, the removal rate of chroma reaches 98.9%, the removal rate of suspended solids reaches 99.2%, and the removal rate of refractory organic matter reaches 98.9%. Harmful microorganisms, The removal rate of viruses and bacteria reaches 96.9%.

Description

Technical field [0001] The invention relates to a rotating cage net type filler electric flocculation reactor, which belongs to the field of water treatment in environmental protection. Background technique [0002] The reaction mechanism of electrocoagulation is to use metals such as aluminum and iron as the anode and cathode. Under the action of direct current, the anode dissolves to produce metal ions. After a series of hydrolysis, polymerization, and ferrous oxidation processes, it develops into various hydroxyl complexes. This kind of hydroxyl complex has a strong flocculation effect; the cathode can reduce the hydrogen ions in the wastewater to hydrogen, and the hydrogen has air flotation. These two effects can remove colloids and suspended substances in the wastewater. Electric flocculation can be widely used for pretreatment such as electroplating wastewater, landfill leachate, pharmaceutical factory wastewater, food wastewater and petrochemical wastewater. The existing ...
