[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] like Figures 1 to 6 As shown, the high-performance circulating fixed-bed reactor for treating black ash water based on optical-magnetic-gas synergy according to the embodiment of the present invention comprises a reactor body, to which an intelligent control system controller 7 is electrically connected;

[0035] A hydrolysis and acidification zone 1 is provided at the center of the reactor body, a spiral guide tube 3 is fixedly installed inside the hydrolysis and acidification zone 1, a bacteria and algae symbiotic zone 12 is provided outside the spiral guide tube 3 inside the reactor body, and a plurality of evenly distributed water outlet holes 2 are provided between the upper part of the hydrolysis and acidification zone 1 and the bacteria and algae symbiotic zone 12;

[0036] The spiral guide tube 3 is provided with a rotating stirring blade 8 on the lower surface thereof, and ultrasonic disturbers 9 are fixedly installed below the left and right sides of the inner wall of the spiral guide tube 3. The spiral guide tube 3 is filled with core seasoning I 11;

[0037] The reactor body is provided with a light guide plate array 5 on the outside, a micro-nano aeration device 6 is fixedly installed on the lower surface of the bacteria-algae symbiotic zone 12, an alternating magnetic field coil 4 surrounds the inner wall of the bacteria-algae symbiotic zone 12, and the bacteria-algae symbiotic zone 12 is filled with core seasoning II 10; when working, the reactor body is configured as a dual-module coupled circulating fixed bed structure, and includes a hydrolysis and acidification zone 1 and a bacteria-algae symbiotic zone 12. When in use, after the black ash water passes through the grille to remove fecal residue, it is lifted by the submersible sewage pump to the bottom of the hydrolysis and acidification zone 1 of the spiral guide tube 3. The spiral guide tube 3 is filled with modified porous ceramic fillers (filling rate 30%), and the water flow rises along the spiral path. HRT = 10h, the rotating stirring blade 8 continuously runs at a speed of 10rpm to enhance solid-liquid mixing; the ultrasonic disturber 9 is used every day The system runs for 10 minutes at 9:00, 15:00 and 21:00 to break the aging biofilm on the surface of the filler. Then, after hydrolysis and acidification, the B / C ratio of the black gray water is increased from 0.25 to 0.5, and then enters the bacteria and algae symbiotic zone 12 through the outlet hole 2. The bacteria and algae symbiotic zone 12 is filled with TiO2 / graphene composite fiber filler (filling rate 45%). A micro-nano aeration device 6 is set at the bottom of the filler, and the light guide plate array 5 is set to a three-layer gradient (bottom layer 2500 lux, middle layer 3500 lux, upper layer 5000 lux) to simulate the natural light cycle (strong light from 6:00 to 18:00, weak light from 18:00 to 6:00). The alternating magnetic field coil 4 outputs a magnetic field strength of 0.15T and runs continuously to induce the formation of bacteria and algae particles. The micro-nano aeration device 6 is at 1.0m 3 / h flow rate air supply, the average bubble particle size is 100nm, and the dissolved oxygen is maintained at 2.0-3.0mg / L. The intelligent control system controller 7 realizes dynamic linkage control of the reactor body through the PLC controller. The intelligent control system collects water quality data every 1h and automatically adjusts the light intensity and aeration volume. Within the 30d operation time, the reactor body has good denitrification and phosphorus removal effects, and the COD removal rate is stable at 94%-97%, and NH4 + -N removal rate is stable at 92%-95%, TP removal rate is 93%-96%;

[0038] Therefore, the reactor body of the present invention adopts a dual-module coupling design. The hydrolysis and acidification zone 1 utilizes a spiral guide tube 3 structure and rotating stirring blades 8, in conjunction with an ultrasonic perturbator 9 and porous ceramic fillers to directionally enrich the hydrolysis and acidification bacterial community and improve the efficiency of macromolecular organic matter decomposition. The bacteria-algae coupling zone integrates a light guide plate array 5, an alternating magnetic field coil 4, and a micro-nano aeration device 6. This promotes algal photosynthesis through a light intensity gradient distribution, and magnetic field-controlled EPS secretion accelerates the formation of bacteria-algae particles. The multi-field synergy of the light guide plate, alternating magnetic field, and micro-nano aeration enhances the efficiency of the bacteria-algae symbiosis. This invention breaks through the efficiency bottleneck of traditional processes, achieving nitrogen and phosphorus recovery rates exceeding 90% and reducing energy consumption by 50%. It is suitable for the efficient treatment and resource recovery of rural black and gray water, and has significant environmental, economic, and social benefits.
