Embodiment Construction

[0033] Such as figure 1 As shown, the device for hydrodynamic cavitation combined with oxidant to degrade dye wastewater of the present invention comprises a stator 9, the two ends of the stator 9 are end caps 15 connected by screws, and the two ends of the end cap 15 are respectively provided with bearing shells 2, bearing shells Angular contact ball bearings 4 are installed in the 2, and the sealing cover 3 is connected to the bearing shell 2, and a sealing ring is arranged at the joint to realize sealing. The stator 9 forms a cavitation chamber through the end covers 15 at both ends thereof. The stator 9 is respectively equipped with a rotating shaft 5 and a rotating shaft 17 through the angular contact ball bearings on both sides. One end of the two rotating shafts is in the cavitation chamber of the stator 9, and the other ends protrude from the left and right end covers of the stator 9 respectively. One end of the rotating shaft 5 in the cavitation cavity is fixedly mou...

Abstract

The invention discloses a device for degrading dye wastewater through hydrodynamic cavitation in combination with an oxidizing agent. The device comprises a stator, a cavitation cavity is formed inside the stator, rotating shafts are installed on the two sides of the stator, wheel discs are fixedly installed the ends, located in the cavitation cavity, of the rotating shafts, the ends, extending out of the stator, of the rotating shafts are connected with transmission devices, cavitation holes are formed in the peripheries of the wheel discs and the inner walls of the cavitation cavity respectively, a liquid feeding pipe and an oxidizing-agent feeding pipe are arranged at one end of the stator, and a discharging pipe is arranged at the other end of the stator. According to the device, two rotors are driven by the two transmission devices to perform relative-high-speed rotation, cavitation holes in the rotors and dye wastewater perform relative movement, and therefore a cavitation phenomenon is caused; cavitation efficiency is improved, the treating capacity of degrading organic matter in dye waste liquid is large, and the device can conduct continuous operation and has effectiveness.

Description

technical field [0001] The invention relates to a device for degrading dye wastewater through hydraulic cavitation technology combined with chemical treatment, and belongs to the technical field of dye wastewater treatment. Background technique [0002] Dye wastewater mainly comes from the dyeing, printing and finishing processes in the printing and dyeing process, which has the characteristics of large volume, high concentration, high chroma and complex composition. Dye wastewater contains a variety of biologically toxic and carcinogenic substances, as well as a variety of refractory harmful substances, among which organic pollutants are the most harmful, and these colored wastewater will undergo oxidation, hydrolysis and other chemical reactions in the environment This forms toxic by-products. If it is directly discharged into the water body, it will seriously affect the light transmission of the water and the growth of aquatic organisms, and it will easily lead to eutrop...
