Background

The quality of the water treatment process in the water factory directly determines the effect of the water quality at the tail end of the water treatment. The existing industrial water plants generally adopt the process steps of wastewater precipitation, filtration, hydrolytic acidification, secondary sedimentation tank, fine filtration, discharge and the like when wastewater treatment is carried out.

In the prior art, a plurality of wastewater treatment technologies exist, for example, a wastewater treatment method and a wastewater treatment system are disclosed in the patent document with the patent application number of CN201310162735.X, and the main steps of the wastewater treatment method comprise the steps of firstly filtering to remove impurities in water, secondly, performing denitrification and dephosphorization treatment and organic matter removal treatment on the filtered water body by using an anaerobic-anoxic-aerobic A-A-O method, thirdly, treating the water body obtained in the second step by using a membrane bioreactor MBR method for intercepting and degrading activated sludge and macromolecular substances in the water body, and fourthly, performing on-line oxidation disinfection on the water body obtained in the third step by using chlorine dioxide.

As can be seen from the descriptions in the patent literature of the wastewater treatment method and the treatment system, the patent mainly carries out filtration treatment, denitrification and dephosphorization treatment and organic matter removal treatment, interception treatment on activated sludge and macromolecular substances in a water body and the like on wastewater in sequence, the treatment process is still remained on the traditional water treatment process, the effect of water quality treatment is poor, the treatment effect cannot be effectively monitored, the treatment mode in each process is more conventional, and therefore, the treatment effect is difficult to achieve when the wastewater, especially the industrial wastewater with high pollutant or concentration is treated by using the technology.

For another example, in patent document CN201910985681.4, a multi-stage treatment wastewater treatment system is also disclosed, the main structure of which includes an adjusting tank for adjusting water quantity and water quality, a primary sedimentation tank for preliminary sedimentation, an anaerobic tank for treating wastewater by using anaerobic technology, an aerobic tank for promoting wastewater treatment by using aeration and oxygenation technology, a secondary sedimentation tank for secondary sedimentation and separating muddy water, a clean water tank for storing treated clean water, a floating equilibrium water delivery mechanism for reducing water quantity impact and facilitating sedimentation, an anaerobic mixing mechanism for mixing muddy water under anaerobic conditions and promoting wastewater treatment, and an active oxygenation mechanism for aeration and oxygenation, wherein both the primary sedimentation tank and the secondary sedimentation tank are provided with floating equilibrium water delivery mechanisms, the anaerobic mixing mechanism is arranged on the anaerobic tank, and the active oxygenation mechanism is arranged on the aerobic tank.

As can be seen from the above-mentioned multi-stage wastewater treatment system, the patent document mainly carries out multi-stage treatment in the conventional wastewater treatment process, but the conventional series stack of the regulating tank, the primary sedimentation tank, the anaerobic tank, the aerobic tank and the secondary sedimentation tank is still utilized in the treatment process, which increases the treatment links as a whole, but the treatment process of each step is not obviously improved, and meanwhile, the treatment effect of the wastewater cannot be effectively monitored, the overall water quality treatment can be improved to a certain extent due to the increase of the working procedures, but the rationality of the overall water treatment is still poor.
