Requirements for Construction of Hospital Sewage Treatment Equipment

Learn the key requirements for construction of hospital sewage treatment systems, including site selection, safety isolation, design principles, equipment standards, auxiliary facilities, cost analysis, and greening measures. Ensure compliance, safety, and efficiency in modern hospital wastewater management.

los construction of hospital sewage treatment equipment is a crucial aspect of medical infrastructure design.
Hospital wastewater often contains pathogens, pharmaceuticals, heavy metals, and disinfectants, which can cause secondary pollution if not properly treated.

Therefore, the design and construction of sewage treatment stations in hospitals must strictly comply with national health, environmental protection, and safety standards to ensure efficient treatment, safe discharge, and sustainable operation.

los location of the hospital sewage treatment station must consider:

• The hospital’s overall master plan and layout;
• los position of discharge outlets and local drainage networks;
• Prevailing wind direction, especially during summer, to avoid odor drifting toward wards or public areas;
• Topography and soil conditions for stable construction;
• Convenient transportation, power, and water supply for easy operation and maintenance.

Tip: The treatment plant should be located downwind of the main hospital buildings and away from sensitive zones such as inpatient wards, kitchens, and residential areas.

• Maintain a safe distance between the treatment station and hospital wards or residential buildings.
• Install green isolation belts o buffer zones to minimize odor diffusion and noise interference.
• Construct fences or enclosed structures around the sewage treatment station, with a minimum height of 2.5 meters for security and restricted access.
• Plan for future expansion—leave sufficient space for capacity upgrades as hospital demand grows.

For hospitals that include infectious disease wards, the production management buildings y living quarters should be centrally arranged but strictly isolated from treatment facilities.
Isolation reduces cross-contamination and ensures the safety of staff and patients.

• The sewage treatment system should be designed with two independent process lines, each handling 50% of the total load to ensure redundancy.
• All treatment structures and buildings must incorporate anti-corrosion, anti-seepage, and anti-leakage measures to ensure long-term durability and operator safety.
• Provide emptying and cleaning facilities in each unit, and recycle drained water back to the treatment process when possible.
• In cold regions, use thermal insulation and heating systems to prevent freezing.
  • Recommended temperatures: ≥5°C in treatment areas and ≥15°C in chemical dosing or monitoring rooms.

• Overhead tanks or elevated units should include railings, non-slip ladders, and lightning protection systems.
• los drainage system should primarily rely on gravity flow, with pumping stations added if topography requires it.
• Equipment should be installed to allow easy access for inspection, maintenance, and replacement.

To ensure stable operation and personnel safety, each hospital sewage treatment station should include:

• Control Room – for monitoring and managing treatment operations.
• Laboratory Room – for regular testing of influent and effluent water quality.
• Duty Room and Office Space – for operators on rotation.
• Communication Facilities – such as control telephones or internal communication systems.
• Emergency Alarms and Safety Systems – including gas detection, overflow alarms, and power backup.

A dedicated storage area must be provided for:

• Sludge and waste residue (kept sealed to prevent odor and bacterial spread).
• Medical waste (stored temporarily and transported according to hazardous waste disposal regulations).

The total investment depends on factors such as:

• Hospital size and wastewater volume,
• Process flow (primary, secondary, or advanced treatment),
• Building structure and local standards,
• Effluent discharge requirements (direct or municipal connection).

Example process types:

• Primary treatment: Adjustment → Coagulation → Sedimentation → Disinfection
• Secondary treatment: Regulation → Biochemical process → Disinfection
• Small-scale systems: Compact biogas purification + disinfection

Cost indicators should be estimated based on national control benchmarks y site-specific parameters.

Operational costs include:

• Energy consumption (pumps, blowers, lighting, heating),
• Chemical usage (coagulants, disinfectants),
• Labor expenses (operator salaries and benefits),
• Maintenance and repair costs,
• Waste sludge disposal and transportation fees.

For accurate budgeting, operating expenses can reference existing hospital wastewater treatment stations with similar scales and processes.

A well-planned green environment not only improves aesthetics but also enhances odor control and noise reduction.

Greening Guidelines:

• Plant odor-absorbing shrubs and trees between the sewage station and nearby wards or residences.
• Choose vegetation that tolerates humidity and can purify the air.
• Keep the area clean and pest-free—as sewage facilities are prone to mosquito and fly breeding, regular disinfection is necessary.
• Maintain a hygienic, and tidy environment around the sewage treatment plant.

los construction of hospital sewage treatment equipment requires a comprehensive approach that integrates safety, functionality, durability, and environmental harmony.
From scientific site selection y robust design to efficient cost management y greening initiatives, every step contributes to creating a safe and sustainable wastewater treatment system for modern healthcare institutions.

Properly designed systems not only ensure regulatory compliance but also play a vital role in protecting public health and the environment.

To prevent unpleasant odors and potential airborne contaminants from drifting toward wards, patient areas, and residential zones.

The fence or enclosed barrier should be at least 2.5 meters high for safety and security.

Install anti-freezing systems o indoor heating to maintain functional temperatures of 5–15°C in operational areas.

Essential facilities include a control room, laboratory, duty station, sludge storage area, and safety monitoring systems.

Through green isolation belts, sealed tanks, and proper ventilation design, combined with regular environmental sanitation maintenance.
