With the continuous development of medical technology, the amount of sewage generated by hospitals is increasing. Screw press dewatering, as an efficient and environmentally friendly sludge dewatering equipment, has gradually been widely used in the field of hospital sewage treatment. In practical applications, hospital wastewater treatment systems first remove large particles of impurities and suspended solids through a screen. Then it enters the regulating tank for water quality and water quantity adjustment. The water out of the regulating tank is pumped and then enters the screw press dewatering machine for treatment. The treated effluent can meet the discharge standards or reuse requirements, and the filter cake is cleaned regularly and disposed of safely. Hospital wastewater mainly includes medical wastewater and domestic wastewater. Sludge dewatering equipment is used in the sludge dewatering process of sewage treatment. The amount of sludge in hospital wastewater is generally not large, so a small sludge dewatering machine is more appropriate. For example, Apo131 or Apo201 can fully meet the requirements.
