Under the condition that the mixed oil exists in the degradation tank 200, the degradation tank 200 can generate a specific purified microorganism, the mixed oil is fully contacted with the purified microorganism in the degradation tank 200 under the full stirring action of the second stirrer 203, the purified microorganism can generate microbial enzymes for promoting the degradation of the oil, the oil substance is hydrolyzed to generate fatty acid and glycerol under the action of the microbial enzymes, the compressed air can provide sufficient air, the aerobic condition in the tank is ensured, the survival and the reproduction of the purified microorganism are maintained, and meanwhile, the sufficient oxygen concentration can further promote the fatty acid to be one by oneStep oxidation to form H2O and CO2. The desired effect is generally achieved within a three week contact time. The degradation tank 200 itself generates a sufficient amount of microorganisms without the need for external addition of microorganisms.
The degradation tank 200 can also include a second water inlet 204 configured to input water into the degradation tank 200. The degradation reaction process of the grease and the microorganisms is an exothermic reaction, the water temperature of the water input from the second water inlet 204 can be controlled to be less than or equal to 42 ℃ in the reaction process, and the mixed grease can be diluted, so that the concentration of the microorganisms is maintained at 10-15 gDS/L.

For example, the sludge produced may be sent to an aeration tank downstream of the sewage plant, and the degradation of grease may continue to be accelerated in the downstream aeration tank, and the growth of filamentous bacteria such as nocardia in the aeration tank may be restricted.
Because the concentration of the pollutant substrate in the degradation tank 200 is high, the biomass in the grease to be treated is more than that required in the grease degradation system 1, and therefore, the discharged activated sludge does not need to be circulated to the grease degradation system 1.
