Embodiment 1
[0039] In this example, the treated soybean processing wastewater is yellow pulp water, in which the COD concentration is 12000 mg / L, the TN concentration is 1300 mg / L, and the TP concentration is 36.2 mg / L. The treatment methods to improve photosynthetic biomass and wastewater treatment effect adopt such as figure 1 The equipment comprises a magnetic field device 8 and a photosynthetic bacteria reactor 1, the wastewater outlet 2 and the wastewater return port 3 of the photosynthetic bacteria reactor 1 are connected with a wastewater pipeline to form a wastewater circulation loop, and a magnetic field device is arranged on the wastewater pipeline 8. Peristaltic pump 5. Pressure gauge 6. A water outlet valve 4 is arranged on the pipe section connected to the waste water outlet 2 . The photosynthetic bacteria membrane bioreactor is a bottle-shaped transparent glass container with a diameter of 15 cm. The diameter of the top return and outlet is 2cm.

Embodiment 2
[0051] In this example, the COD concentration in the treated soybean processing wastewater is 13800mg / L. Carry out magnetic field treatment to improve photosynthetic biomass and wastewater treatment effect, such as figure 1 Equipment, including: photosynthetic bacteria reactor unit, high-intensity magnetic field unit.
[0052] Adopt the equipment identical with embodiment 1, comprehensive processing step:
[0053] 1. Test the COD concentration of soybean processing wastewater to be 13800mg / L, and adjust the pH to 6.9;
[0054] 2. Take 1.6L of adjusted soybean processing wastewater and add it to the photosynthetic bacteria reactor, and add 0.4L of the photosynthetic bacteria mixture that has reached the plateau stage. The final photosynthetic bacteria concentration is 1000mg / L dry weight, and the total liquid volume is the main body of the reactor two-thirds of volume;
[0055] 3. Select a high-intensity magnetic field device with a magnetic field strength of 0.8T, and conne...
