Sludge treatment method

[0033] A sludge treatment method is characterized in that comprising the steps of:

[0034] Primary treatment: pass the sludge through the grid plate for preliminary filtration;

[0035] Ultrasonic treatment: Ultrasonic treatment is performed on the sludge that has undergone primary treatment, and the vibration frequency is 40KHz;

[0036] Ozone fermentation treatment: mix the ultrasonically treated sludge with the fermentation liquid, add a pH regulator, adjust the pH to 5.0-6.5, and the treatment time is 2-4 days, during which the generated gas is collected;

[0037] Solidification treatment: add solidification agent to the sludge treated by ozone fermentation, and treat it for 30-50 minutes.

[0038] Pyrolysis treatment: heat the solidified sludge to 450-550°C, and the treatment time is 1-2h, during which the generated gas is collected.

[0039] The pH regulator includes acetic acid and sodium bicarbonate, the fermentation broth includes Bacillus pumilus, Enterobacter cloac...
