| description | The invention provides an onion biochar catalyst for degrading odor substances in a water body and a preparation method thereof, and the preparation method comprises the following steps: step S1, carrying out acid treatment, suction filtration and cleaning on onion powder to obtain treated onion powder; and S2, adding the treated onion powder into a ferric citrate solution, performing ultrasonic dispersion, adding melamine, mixing, performing ultrasonic treatment, centrifuging, cleaning, drying, grinding, and performing pyrolysis at 800-1000 DEG C for 0.5-3 hours to obtain the onion biochar catalyst. With the adoption of the technical scheme, potassium peroxymonosulfate (PMS) can be catalyzed to degrade odor substances such as geosmin (GSM) and dimethyl isoborneol 2-MIB in a water body, only a small amount of catalyst needs to be added, the removal rate can reach 90% or above, and the treatment effect is better; and the preparation method is simple, low in cost and easy for large-scale production.
