Embodiment 1

[0093] Figure 1 and Figure 2 show the application examples of the modular opto-electromagnetic integrated wastewater oxidation device with a processing capacity greater than 2 tons per hour. As shown in the figure, it includes a photocatalytic box 1, a micro-electrolysis reactor 2 and a filter 3, and the three are connected in sequence. The outer end of the photocatalytic box 1 is connected with a photocatalytic box inlet pipe 11 and a photocatalytic box outlet pipe 14. The water inlet pipe 11 of the photocatalytic box is connected to the organic wastewater pool (omitted in the figure), and the organic wastewater that has been acidified and pretreated can be introduced to carry out photocatalytic treatment. The water inlet pipe 11 of the photocatalytic box is covered with a magnetizer 111. The magnetic field strength of the magnetizer is 12000-20000 Gauss and can be made of ferrite or NdFeB. The water outlet pipe 14 of the photocatalytic box is connected to the micro-electrolys...

Embodiment 2

[0108] As another embodiment of the present invention, the micro-electrolysis reactor 2 in the embodiment one can also adopt the structure of following water inlet at the bottom:

[0109] In the present embodiment, photocatalytic box 1 and filter 3 structures are basically the same as embodiment one, and micro-electrolysis reactor 2 is provided with dividing plate 211 that it is divided into upper and lower cavity, as shown in Figure 4 and Figure 5, The separator 211 is connected to the negative pole of the external power supply, and the upper and lower cavities are communicated through the round holes on the separator. The upper cavity is provided with an iron-carbon tube 202 with built-in electrode material at the round hole of the separator, and the structure of the iron-carbon tube can be the same as that of the first embodiment. The lower chamber is provided with a reactor water inlet pipe 201 and a microporous aeration head 206, and has a positive metal plate 212 connect...

Embodiment 3

[0114] Figures 7 and 8 show an application example of an integrated device with a processing capacity of less than 2 tons per hour. As shown in the figure, it is composed of an upper box photocatalytic box 1 and a lower box micro-electrolysis reactor 2. The photocatalytic box 1 is provided with partitions 12, and multiple groups of ultraviolet lamps 13 are installed between the partitions 12. The bottom layer between the ultraviolet lamps 13 can choose whether to install a microporous aeration head (the device that is too small can not be installed) ), the ultraviolet lamp 13 is covered with a quartz sleeve 132. The outer end of the photocatalytic box 1 is connected with the photocatalytic box inlet pipe 11 and the photocatalytic box outlet pipe 14. The photocatalytic box inlet pipe 11 is covered with a magnetizer 111, and the photocatalytic box outlet pipe 14 passes through the reactor inlet pipe 201 and the micro-electrolysis reactor. 2 connected. The micro-electrolysis re...

Abstract

This invention relates to a photoelectromagnetic integrated advanced oxidation method and its device for waste water, which first of all acidizes the waste water, then strongly magnetizes it to generate energy of physical change and chemical change then enters into a photo-catalyzing box to be oxidated mostly to CO2 and water under the actioin of photo-catalyst, ultraviolet light, ozone and oxydol, in which, molecular chains of some hard-degradated substances are broken, then the waste water is micro-electrolysed to adsorb and recover the hard degraded substances under the action of extra low voltage, weak current and air, ozone and oxydol to get rid of COD, color degree, deodorizatin and disinfectant finall to filter it by diatomite and filter out suspending substances to reach the standard or recover it.

Description

【Technical field】 [0001] The invention relates to a wastewater treatment method and a device thereof, in particular to an advanced oxidation method and equipment for treating high-concentration organic wastewater using optoelectronic and electromagnetic integration. 【Background technique】 [0002] With the rapid development of social economy, the industrialization and urbanization of human society are increasing day by day, and the phenomenon of water pollution is becoming more and more serious. Especially the landfill leachate produced by municipal solid waste landfills or waste incineration power plants that represent high-concentration organic wastewater. High concentration of pollutants, large changes in water quality, strong stench, yellowish brown or taupe. The main pollutants in landfills are organic pollutants, ammonia nitrogen, phosphorus, heavy metals, etc., COD Cr It can reach thousands to tens of thousands of mg / L, and the pH value is generally between 6.5 and ...
