Description

TECHNICAL FIELD

[0001] The utility model relates to iron carbon micro electrolytic device technical field, concretely relates to a lifting type iron carbon micro electrolytic anti-caking reaction device. BACKGROUND

[0002] Iron carbon micro electrolysis technology is a pretreatment method widely used in wastewater treatment, mainly composed of iron powder and carbon material. Iron powder as anode, carbon material acts as conductive medium. The technology uses the electrochemical difference between iron and carbon, and realizes the purification of wastewater through the physical and chemical action of micro electrolysis. Its decontamination mechanism covers precipitation, adsorption and reduction and other mechanisms, which can effectively remove suspended solids, heavy metals, organic pollutants and some pathogens in wastewater. At present, the iron carbon micro electrolysis system on the market mainly adopts the design of fixed bed reaction tank or reaction tower. In these reactors, the water inlet and air inlet pipeline are arranged at the bottom, and the top is equipped with a porous glass steel or stainless steel support plate. On the support plate, different shapes of regular iron carbon fillings are stacked, and the filling height can reach several meters, or stacked in multiple layers. These regular fillings form a fixed bed in the reactor, and the particles are in contact with each other and have various sizes of voids. Another design is to place the iron carbon fillings in the hollow filler column, and place the filler column vertically on the support plate. This design is different from the traditional disordered accumulation fixed bed, which allows acidic water flow and gas flow to flow upward from the bottom of the filler bed, thereby promoting the contact reaction of gas, liquid and solid three phases.

[0003] The close packing of iron carbon fillings leads to the hydrolysis of part of ferrous iron to form ferrous hydroxide and ferric hydroxide in the iron carbon micro electrolysis system operated in the aeration environment. These substances are easy to adsorb in the voids of the fillings or the areas where the water flow and gas flow are difficult to fully contact, and gradually form a passivation film, thereby hindering the electrochemical reaction between iron and carbon and reducing the reaction rate. With the long-term operation of the system, the growth and adhesion of the passivation film cause the caking of the iron carbon particles, which further affects the treatment effect. The iron carbon fillings are generally placed in the middle and lower part of the pool body, which makes it difficult to monitor the caking of the fillings during system operation, and the degree of caking and the amount of material cannot be directly evaluated. After the pool water is pumped out, the fillings can be inspected and replaced. If the fillings are seriously caked, the fillings will be integrally adhered and difficult to separate and take out, which may lead to unsatisfactory wastewater treatment effect, and at the same time, the micro electrolysis pool cannot be reused, increasing the economic cost.
