The working flow is as follows:
Firstly, wastewater generated by an industrial enterprise water process enters a detection bin 1 through a pipeline (DN 300). The characteristic of spectral fingerprint is formed by utilizing the difference of the absorption/reflection characteristics of different pollutants on light in a specific wave band, spectral scanning is carried out, wherein ultraviolet wave band (200-400 nm) is used for detecting characteristic absorption peaks of organic matters (such as benzene series and phenols), fluorescent wave band (excitation 280 nm/receiving 450 nm) is used for identifying oil-containing pollutants, terahertz wave band (0.1-3 THz) is used for penetrating through a high-turbidity water body and detecting suspended particles (such as metal particles and microplastic). And then summarizing the scanning result (namely, the data acquired by the sensor) to a controller, outputting a pollutant type signal through a preset classification algorithm (such as threshold comparison), and triggering subsequent module parameter adjustment (such as setting a rotating module rotating speed in the cyclone separator 2).
After the wastewater enters the cyclone separator 2, the pollutants in the wastewater are subjected to cyclone separation through the cyclone separator 2, and the rotating speed of the rotating module arranged in the cyclone separator 2 is matched with the type of the pollutants fed back in the previous step. The rotational speed (500-3000 rpm) of the cyclone separator 2 is dynamically regulated according to the spectrum detection result, heavy pollutants (density >1.2g/cm3, such as metal particles) are gathered towards the pipe wall under the action of centrifugal force (> 500 g) and discharged through a slag discharge port 18, light pollutants (density <0.9g/cm3, such as oil and organic matters) are gathered towards the pipe center and collected by a top oil discharge port 17, and medium turbidity water body keeps a laminar flow state and enters the next link.
A certain direct current voltage (the voltage is intelligently regulated and controlled according to the type of the pollutant signal detected by the spectrum) is applied to a pair of electrodes 7, so that directional salt migration is realized under the action of an electric field, salt ions (such as Na+, cl-and the like) are driven to migrate through an ion exchange membrane 8, then high salt water is discharged from a drain pipe 21, the evaporation treatment process can be carried out later, and the high salt water is not recycled. Meanwhile, the high-speed water flow in the cyclone separator 2 flushes the surface of the ion exchange membrane 8, so that the scaling risk is reduced. The low-salt water (desalination rate > 90%) is treated in the treatment bin 9 as industrial reuse water.
The back of the cyclone separator 2 is connected with an on-line conductivity device 12, the low-salt water after desalination is subjected to on-line conductivity detection, the water reaching the standard is pumped to a reuse water pipe network through a reuse port 13, and the water not reaching the standard is returned to the desalination bin 3 through a return pipe 14 for secondary treatment.
