Method for improving dewatering performance of municipal sludge at low temperatures

The invention belongs to the technical field of sludge treatment and particularly relates to a method for improving dewatering performance of municipal sludge at low temperatures. According to the method for improving the dewatering performance of the municipal sludge at low temperatures, utilized microorganisms are low-temperature acclimated compound microorganisms, the low temperatures are 10-15 DEG C. Under the conditions of 10-15 DEG C and through 2-5 days' recreation, the method for improving the dewatering performance of the municipal sludge at low temperatures can obviously improve the dewatering performance of the municipal sludge; the moisture content of filter-pressed and caked sludge can be reduced below 60%.
