Project Overview
- The Jianhu County Hospital Wastewater Treatment Upgrade Project is a supporting upgrade project for the hospital campus, primarily involving the expansion, renovation, and process optimization of the existing wastewater treatment facilities.
- The project is designed with a treatment capacity of 1,500 m³/d and has been completed and put into operation.
- The medical wastewater generated by the hospital includes diagnostic and therapeutic wastewater, laboratory waste liquids, and domestic sewage, characterized by elevated concentrations of organic matter, suspended solids, and bacterial colonies, along with trace amounts of specific hazardous pollutants.
Key Technical Challenges
- Wastewater quality and flow rate fluctuate significantly between day and night, with peak diagnostic hours potentially causing shock loading, demanding high process adaptability and fluctuation resistance.
- Strict control of pathogenic microorganism disinfection is required to ensure stable compliance of disinfection indicators such as fecal coliforms, meeting the mandatory discharge standards for medical institutions.
- Targeted pretreatment is required for special waste liquids from the laboratory department, effectively degrading organic matter and suspended solids to stabilize water quality and meet downstream process and pipeline connection requirements.
Process Flow
Medical wastewater → Pretreatment → Collection Well → Equalization Tank → Biological Treatment System → Sedimentation Tank → Disinfection Tank → Dechlorination Tank → Compliant Discharge
