Abstract:
The technological transformation of sludge treatment system in a wastewater treatment plant (WWTP) in Shiyan, Hubei Province was introduced. A combined process of mechanical thickening, sludge conditioning and modification, and high-pressure filter was used and the water content of sludge was decreased from 99.5% to below 60% after deep dewatering, which met the requirements of Disposal of Sludge from Municipal Wastewater Treatment Plant-Quality of Sludge for Co landfilling (GB/T 23485-2009). The problem of poor dewatering performance in the sludge treatment system was effectively solved.
