A Maternal and Child Health Hospital in Chengdu

Wastewater treatment in maternity and child health hospitals generally follows national and local environmental regulations to ensure that the discharged water quality meets the corresponding standards.

According to typical wastewater treatment processes, the wastewater treatment system of a maternity and child health hospital may include the following steps:

Collection and Conveyance: Wastewater generated by the hospital is first collected through sewer pipes and conveyed to the wastewater treatment station.

Pretreatment: Before entering biological treatment, the wastewater passes through screens to remove larger suspended solids, then flows into an equalization tank to regulate water quality and flow, and finally undergoes sedimentation to remove some suspended solids and organic matter.

Biological Treatment: Aerobic or anaerobic biological treatment methods are used to remove organic matter and other pollutants from the wastewater.

Advanced Treatment: Further removes fine suspended solids, residual organic matter, and pathogens from the wastewater. This step typically includes sand filters, activated carbon adsorption tanks, and disinfection tanks.

Resource Utilization: The sludge generated during the treatment process is dewatered and efforts are made to utilize it as a resource, for example through composting or use as a building material. Simultaneously, measures such as biogas energy recovery are considered.

Discharge and Monitoring: Before the final purified wastewater is discharged into the municipal sewer network, it is subject to real-time monitoring by an online monitoring system to ensure compliance with national standards.
