Usually, water sources after industrial use contain some substances that are harmful to the environment or human body. If the harmful substances in industrial wastewater are discharged directly without treatment, they will cause serious damage to the water ecosystem, affect the survival and reproduction of aquatic organisms, and may even affect human health through the food chain. Therefore, the treatment of industrial wastewater is very necessary.

[0006] In order to solve the above technical problems, the present invention provides a special wastewater degradation and disinfection treatment equipment, which includes a degradation box, which is connected to a catalytic box body at the rear, a filter screen is installed in the degradation box, and the filter screen divides the degradation box into a filter chamber and a degradation chamber. A decomposition mechanism is arranged inside the degradation chamber, and the decomposition mechanism includes a degradation pool. In the degradation chamber, mounting plates are installed in parallel on the inner wall, and the degradation pool is installed on the mounting plate through an assembly seat. Catalytic disks are arranged side by side inside the degradation pool and are connected in series through a shaft rod.

Inside the catalytic box, rotating disks are installed in parallel on the motor shaft of the speed regulating motor, and reaction light source tubes are provided on both sides of the rotating disk.

[0008] Preferably, one end of the catalytic housing is connected to the adding housing through a connecting pipe, and a power device is installed on the adding housing.

[0009] Preferably, an exhaust device is installed on a fixing column away from the speed regulating motor, and an exhaust pipe of the exhaust device is inserted into the catalytic housing.

[0010] Preferably, a communication device is installed on the inner wall of the degradation chamber, and a communication rod of the communication device passes through the mounting plate and is connected to the shaft rod of the catalytic disk.

[0015] A treatment method for special wastewater degradation and disinfection treatment equipment, comprising: S1. Filtration Connect the water inlet pipe to the wastewater outlet, then open the valve switch, and the wastewater will enter the degradation box through the water inlet pipe. The filter in the degradation box will isolate the larger impurities in the wastewater, and the larger impurities in the wastewater will be retained in the filter chamber; S2. Decomposition After the filtered wastewater enters the degradation chamber of the degradation box, an external control device is used to operate the catalytic disk through a communication device, and at the same time, the ultraviolet light source tube is turned on. The wastewater will be in the degradation chamber, and the ultraviolet light irradiation and the catalytic disk will work together to achieve the decomposition of trace organic matter in the wastewater and the killing of bacteria and viruses; the catalytic disk can be designed as a titanium oxide plate, which will produce highly active free radicals such as hydroxyl free radicals (0H) after ultraviolet irradiation.

Reaction Processing After the decomposition treatment is completed, the wastewater enters the catalytic box. At this time, the power device is turned on to add the catalyst in the box into the catalytic box and merge with the wastewater. Then the reaction light source tube and the speed regulating motor are turned on. The speed regulating motor rotates the rotating disk. Under the catalysis of the light source, the catalyst will combine with the dirt in the wastewater to further clean the wastewater. The rotation of the rotating disk stirs the wastewater and accelerates the fusion of the catalyst and wastewater. At the same time, the stirring of the wastewater also increases the efficiency of the light source absorption reaction.

The catalytic disks in the decomposition mechanism are arranged side by side, and the ultraviolet light source tube can be used to decompose the organic matter in the wastewater in time and kill the detailed viruses in coordination, so that the treatment is simple and the treatment efficiency is high. At the same time, the part of the catalytic disk that rotates out of the water surface can be irradiated and catalyzed by the ultraviolet light source tube, so that the light absorption rate is better, and the fixed catalytic disk is prevented from being located underwater, and the light absorption rate is not high due to the turbidity of the sewage; 2. The present invention arranges a catalytic mechanism in the catalytic box. Under the action of the rotating disk and the reaction light source tube, the decomposed wastewater can be further treated by the catalyst. The wastewater is further catalytically cleaned on the basis of decomposition, which further increases the treatment efficiency and the degree of wastewater cleaning, and prevents harmful substances in the wastewater from being insufficiently cleaned and flowing into the natural environment for use.
