Taking the multi-material liquid mass transfer reaction for sewage standard treatment as an example, the application method of the fluidization reactor comprises the following steps:
step 1, sewage enters a cyclone distribution pipe 3 through a water inlet 2, and the tangential rotation distribution flow of the effluent enters a cyclone distribution mixing zone B under the guiding action of the cyclone distribution pipe 3 under the impact of the water flow speed;
step 2, a first material adding point 18 and a second material adding point 19 are respectively arranged near the outlets of the two cyclone distribution pipes 3, and 1 or more water treatment additives (nutrient, medicament and the like) are respectively added, and the added additives meet the rotary sewage flowing out of the cyclone distribution pipes 3, so that efficient stirring and mixing are realized; meanwhile, the cyclone distribution pipes 3 may be two or more in annular arrangement according to the size of the reactor and the actual use requirement;
step 3, through rotating mixing water distribution, water flows annularly flow to the outer side of a rotational flow distribution mixing zone B, high-speed jet air flows generated by outlets of a rotational flow plug flow air distribution pipe i 10 and a rotational flow plug flow air distribution pipe ii 11 arranged on the outer side act on rotational flow water bodies, rotational flow and stirring mixing speed of sewage and additives in the rotational flow distribution mixing zone B are improved, so that mass transfer efficiency is improved, efficient primary mixing reaction is realized, and a foundation is provided for subsequent deep reaction treatment;
step 4, the rotational flow mixed water body is uniformly distributed into a rotary diversion mixing reaction zone C through rotational flow distribution outlets 5 at the lower part of a rotational flow distributor baffle plate 4, and flows downwards in a rotary diversion manner under the inertia effect, and when fluid flows through a rotary guide vane 6, the rotary mixing flow state of the fluid is maintained and enhanced under the diversion effect of the rotary guide vane 6, so that the mass transfer efficiency is improved, and the reaction effect is enhanced;
step 5, the rotational flow mixed water body reaches the lower part of the reactor tank body 1, efficient air-water mixing is realized through the air stripping release of an air-lifting power air supply pipe 12 arranged at the lower part, the air-water mixture has low density and small weight pressure in the air-lifting power air supply pipe 7, the pressure difference effect causes upward floating of fluid, and in addition, the water body is pushed to float upwards under the action of the pushing force of jet air flow formed by the air-lifting power air supply pipe 12 at high speed; under the action of the double principle, a large amount of water (16-60 times of water inflow can be achieved) is efficiently sucked into a horn mouth at the lower part of the airlift power riser 7, and flows up to the top of the airlift power riser 7 and overflows to the swirl distribution mixing zone B uniformly;
step 6, in the step 5, the reflux liquid (16-60 times of water inflow) meets the sewage inflow water flow of the rotational flow distribution mixing zone B and the corresponding water treatment additives, so that high-rate and high-efficiency mass transfer high-speed rotational flow stirring mixing of the reflux liquid, inflow water and various additives is realized, the water homogeneous mixing reaction effect is remarkably improved, and meanwhile, the water inflow fluctuation impact resistance of the system is improved;
step 7, fully mixing the reflux liquid, the inlet water and the rotational flow mixed liquid of various additives, and circularly repeating the steps 1-6;
step 8, a small amount OF water (with water inflow) reaching the standard is discharged through the water outlet flow path CF (see fig. 4) downwards along the peripheral area OF the reactor tank 1, flows through the water outlet collection water distribution holes 17 to the water outlet collection ring pipe 14, and finally reaches the standard through the water outlet 16 while most OF water (with water reflux) flows through the circulating flow path OF (see fig. 4) OF steps 1-7 to fully react in a circulating way.

Meanwhile, the cyclone mixing effect can be guaranteed and improved by improving the gas release strength of the inlet 2 and the cyclone distribution outlets 5, so that the settings of the power air supply port I8, the power air supply port II9, the cyclone plug flow gas distribution pipe I10 and the cyclone plug flow gas distribution pipe II 11 can be canceled, the structure of the reactor is further simplified, and the cost is saved.
