Abstract
The utility model relates to a sewage treatment apparatus by electrochemical method, composed of an electrooxidation part and an electrocoagulation part. In the electrooxidation part, the electric current density of bipolar electrodes which are composed of insoluble mesh-shaped polar plates and chargeable particles can reach 10-20 A/dm +[2]. In the electrocoagulation part, iron and aluminium are used as soluble electrodes which can generate coagulant, such as ferric hydroxide and aluminum hydroxide for next processing. The utility model can achieve the purpose of purifying the wastewater which is produced by printing and electroplating with high efficiency and energy saving process. No medicament need to be added, so a medicament casting system is saved, and the salt content of the water can not be increased. The utility model is favorable for recycling water.
Description
The utility model relates to the device that a kind of electrochemical process that is specially adapted to processing waste water containing chrome and dyeing waste water is disposed of sewage.
Existing electrochemical process mainly is with electrolytic process processing waste water containing chrome and dyeing waste water device, is to adopt electrolysis to add dispensing and the electrocoagulation treatment and purification sewage that forms, does not carry out electrooxidation before electrolysis treatment.
At home, have and before electrolysis, add iron trichloride as electrolytic coagulant, and to the electrolysis water outlet with lime deionized and decoloured (CN85106939A), this method needs to increase administration system and the overhead charges except dispensing, its pole plate all adopts the solubility battery lead plate, and the butted line battery lead plate also must equally regularly replace with intermediate electrode plate.
The device (CN86203520U) that replaces low-voltage dc power supply electrolysis treatment dyeing and printing sewage with the high-voltage pulse electrolysis is arranged, and its pole plate all adopts the solubility battery lead plate, and the butted line battery lead plate also must equally regularly replace with intermediate electrode plate.
Adopted monopolar cell (CN85109756A) in the U.S., every pole plate all needs wiring, more tired fiber crops when changing pole plate.
Adopted bipolar cell in Japan, the parts of this equipment are many, structure, processed complex (CN86107225A).
Above prior art is not all carried out the electrooxidation stage and is directly carried out electrolysis treatment sewage.
The purpose of this utility model is to provide a kind of electrochemical process device of disposing of sewage, and is made up of electrooxidation and electrocoagulation two portions.Sewage carries out electrocoagulation again through electrooxidation earlier.
In the electrooxidation part, by the bipolar electrode of the many electrifiable granulometric composition between insoluble netted pole plate and pole plate, current density reaches 10～20 amperes/decimeter
2, direct decomposing harmful substances destroys the molecular bonding structure of dirt in the sewage, reaches the purpose of purifying waste water, and has improved processing efficiency, has saved electric energy.The rear portion of this device is to be link electrode with insoluble mesh electrode, is one or more groups electrode plate groups of target with solubility electrode (its electrode materials can select for use iron or aluminium or iron to add aluminium), and current density is 0.4～0.5 ampere/decimeter
2, because iron and aluminum ion that anode dissolution produces generate extremely strong coagulating agent, can not add other chemical agent and can carry out coagulation sewage, reach the purpose of purifying waste water through equipment for separating liquid from solid again,, also can not increase the saltiness that purifies back water owing to do not add other chemical agent.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a schematic perspective view of the present utility model.
The feature of electrooxidation part is by water inlet manifold (1), water inlet control valve door (2), diffuser tube (3), ring flange (4), insoluble mesh electrode plate (5), terminal stud (6), ring flange (7), bolt (8), plexi-glass tubular (9), electrifiable granular filler (10), reducing pipe (11), manifold trunk (12) is formed.Water inlet manifold (1) welds with the lower end of diffuser tube (8) or is bonding, and diffuser tube (3) forms with plastic plate Volume weldering, is down taper, and the upper end has ring flange (4) to be connected with bolt with the ring flange of plexi-glass tubular (9) lower end.It is a plurality of that two ends have the plexi-glass tubular (9) of ring flange, all connects with bolt.Electrifiable granular filler (10) is housed in each section plexi-glass tubular.Reducing pipe (11) is positive taper, forms with plastic plate Volume weldering, and the lower end has ring flange (7) to be connected with bolt with plexi-glass tubular ring flange topmost.Be equipped with the insoluble mesh electrode plate of seal washer and garden shape (5) between every group of ring flange.The upper end of reducing pipe (11) and manifold trunk (12) welding or bonding.The positive and negative supply lead of insoluble mesh electrode plate and transmission line joins.After sewage enters this device, by just (+), negative (-) electrode are connected direct supply, sewage will carry out oxidation under the effect of positive and negative electrode, built-in granular filler, be subjected to drainage flow from bottom to top and be suspended state, each particle all is subjected to the electrode effect and forms the electrified body with positive and negative electrode, under big density galvanic action, battery lead plate and particle all carry out electrooxidation to sewage, thereby have improved the oxidation efficiency to sewage.
Electrocoagulation partly comprises water inlet pipe (21), the cell body of Chang Kaiing (20) above, intermediate electrode plate (22), wiring mesh electrode plate (27), (28), catchment tray (23), total rising pipe (24), compressed air inlet pipe (25), scum pipe (26) is formed.The water inlet pipe (21) of electrocoagulation part is connected with the manifold trunk (12) of electrooxidation part, and water inlet pipe (21) is connected with the preceding bottom of cell body (20).The rectangular parallelepiped that opens wide above cell body (20) is, be equipped with in the groove be parallel to each other and with groove bottom and long trough wall surface vertical rectangular metal (iron or aluminium) plate (being intermediate electrode plate (22)) and the insoluble rectangle mesh electrode of wiring plate (negative plate (27) wherein simultaneously, positive plate (28)), position relation between intermediate electrode plate and the link electrode plate is that polylith intermediate electrode plate (22) is housed between link electrode plate (27) or (28).The positive-negative power line can directly be welded in the upper end of link electrode plate, and also available terminal stud links to each other.With the relative water side of cell body (20) feed-water end, be provided with catchment tray (23), current enter total rising pipe (24) by catchment tray (23).Be provided with scum pipe (26) with the eliminating sediment in cell body (20) bottom, and the bottom is furnished with the porous compressed air pipe in cell body, to reach with the uniform purpose of pneumatic blending.
