[0020] Refer to Figure 1As shown in the figure, an embodiment of a combined process treatment device for hard glue wastewater of the present utility model includes a flocculation sedimentation reactor 1. The flocculation sedimentation reactor 1 includes a flocculation zone 2, a coagulation zone 3, and a sedimentation zone 4.

An ozone generator 9 is connected to one side of the ozone catalytic oxidizer. It includes a water inlet pipe 17, and the water inlet pipe 17 is arranged at a position outside the flocculation sedimentation reactor 1 near the flocculation zone 2.

[0021] It includes a first chemical dosing tank 10. The first chemical dosing tank 10 is connected to the flocculation zone 2 of the flocculation sedimentation reactor 1 through a pipeline. The chemical agent stored in the first chemical dosing tank 10 is polyacrylamide, which is a water-soluble polymer. It is insoluble in most organic solvents, has good flocculation properties, can reduce the friction resistance between liquids, and can be classified into four types: non-ionic, anionic, cationic, and amphoteric according to ionic characteristics. Polyacrylamide flocculants are widely used in aspects such as thickening, stabilizing colloids, reducing resistance, bonding, film-forming, and biomedical materials. In water treatment, it is used as a coagulant aid, flocculant, and sludge dewatering agent. In oil drilling and production, it is used as a water precipitation agent and oil displacement agent. In the papermaking process, it is used as a retention aid and strengthening agent.

[0022] It includes a second chemical dosing tank 11. The second chemical dosing tank 11 is connected to the coagulation zone 3 of the flocculation sedimentation reactor 1 through a pipeline. The chemical agent stored in the second chemical dosing tank 11 is polyaluminum chloride, which is an inorganic substance, a new type of water purification material, an inorganic polymer coagulant, abbreviated as polyaluminum. It is a water-soluble inorganic polymer between AlCl3 and Al(OH)3, and its chemical general formula is [Al2(OH)nCl6-n]m, where m represents the degree of polymerization and n represents the neutrality of the PAC product. When n = 1-5, it is a high-charge polymer ring chain body with a Keggin structure, which has a high degree of electro-neutralization and bridging effect on colloids and particulate matters in water, and can strongly remove micro-toxic substances and heavy metal ions, and its properties are stable.

[0023] It includes a third chemical dosing tank 12. The third chemical dosing tank 12 is connected to the ozone catalytic oxidation reactor 8 through a pipeline. The chemical agent stored in the third chemical dosing tank 12 is hydrogen peroxide.

[0025] In use, the sewage is lifted by the front-end primary lift pump and then enters the flocculation sedimentation reactor 1. Flocculants and coagulants are added in the reactor to form flocs from large particulate matters, which then precipitate in the sedimentation area 4, achieving the removal of rubber particles in the wastewater. The electrocatalytic high-efficiency reactor 6 adjusts the current to cause electron movement to form a large number of free radicals, degrading the pollutant concentration in the wastewater and using the oxide film formed by the plating metals such as platinum on the electrode surface to degrade Nekal, reducing the biological toxicity. Then, it undergoes in-depth treatment through the HPS enhanced ozone catalytic oxidation reactor 8 to break the carbon chain of the organic matter, so as to reduce the pollutant concentration in the wastewater.
