| Summary: | The invention relates to an efficient sludge dewatering method which is characterized by comprising the following steps: (1) performing acidification reaction on sludge, adding polymeric ferric sulfate salt accounting for 3-5% of the specific gravity of the sludge into the sludge, stirring, adjusting the pH value of the sludge to 6-8, and stirring for 5-15 minutes to obtain acidified sludge; (2) performing oxidation-reduction reaction on the acidified sludge, adding hydrogen peroxide accounting for 0.3-1% of the proportion of the sludge into the acidified sludge, stirring for 5-15 minutes, and fully reacting to obtain sludge in a sponge net state; (3) carrying out temperature acceleration chemical reaction, and heating by adopting a heating pipeline with the temperature of 36-40 DEG C; according to the method, the dehydration rate of the sludge can be improved, and the sludge cake with the water content within 35% is obtained and can be better recycled.
