Abstract:Take the design of sludge deep dewatering process of a waste water treatment plant in Dongguan as an example, through the economic and technical analysis, such as floor space、total investment、operating cost and so on, and comparison of three different sludge treatment process combinations, application situation of the three different sludge treatment process combinations are obtained. At the same time, according to the shortage of floor space and total investment of this project, the “mud-storge basin + mechanical thickening + Pharmacy conditionging + Ultra high pressure plate and frame filtration” process is used as sludge treatment process, and then the sludge deep dewatering process is detailed designed, water content of the sludge could be controlled at below 60%, which provides a reference for similar engineering design experience.
