Device for degrading dye wastewater through photocatalytic oxidation

Abstract

The invention discloses a device for degrading dye wastewater through photocatalytic oxidation. The device comprises a device box, and a water inlet and a water outlet which are formed in the rear surface of the device box; a motor is mounted at the top of the device box, and the output end of the motor is connected with a one-way driving assembly; a transmission assembly is arranged on the outer side of the one-way driving assembly; and a first steering assembly and a second steering assembly are arranged on the two sides of the top of the device box correspondingly. According to the device, a plurality of steps can be met only by using one device box, so that the space is saved for a factory; meanwhile, one motor can meet a series of steps of pretreatment, precipitate precipitation, photocatalytic oxidation and photosensitizer precipitation of the dye wastewater, so that resources are greatly saved; and meanwhile, the motor does not need to be shut down, so that dye wastewater treatment continuity is high, time can be greatly saved, meanwhile, the working efficiency is effectively improved, and the national call of saving resources is responded.

Description

Technical field [0001] The present invention relates to the field of wastewater treatment, and is specifically a device for photocatalytic oxidation degradation of dye wastewater. Background technique [0002] The textile industry also causes huge economic benefits to cause water environmental safety, especially in the important part of printing as a textile industry chain, emitting pollutants of the entire industrial chain, according to statistics, and each year The printing and dyeing waste is more than 2.45 billion tons, accounting for 12% of China's industrial waste water emissions. At the 3rd place in 41 statistics, the printing and dyeing waste is complex, and the main pollutants are from a large number of processing. Dyes, chemical agents, there are many toxic, harmful substances, water quality, biodegradability is also poor, is a known difficult to treat industrial wastewater, in recent years, semiconductor photocatalytic technology is considered a green Energy-saving env...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems still exist when using the device for photocatalytic oxidation degradation of dye wastewater to treat wastewater: 1. The treatment steps are particularly cumbersome, often requiring more equipment to process step by step, not only the efficiency is not improved, on the contrary, it is also greatly improved Occupies the available area resources; 2. Due to the large number of equipment, it has caused great troubles in how to use power resources reasonably and effectively, which makes the huge power consumption of the factory and increases the cost of the factory. It does not respond to the national energy conservation and environmental protection. calls, a waste of resources
