Chengdu Medical Wastewater Treatment Project by Baihuipu
A hospital project in Chengdu required a safe and reliable medical wastewater treatment system. Baihuipu supplied an integrated package that handles sewage collection, biological treatment, and advanced disinfection to meet the stringent requirements for medical effluent.
Challenges of Hospital Wastewater
Medical wastewater may contain pathogens, pharmaceutical residues, disinfectants, and radioactive substances depending on the department mix.
Regulations require higher disinfection standards than ordinary domestic sewage. We have written about the downstream implications separately in Urea Hydrolysis, Ammonia Recovery and Ammonia Rebound.
System reliability is critical because hospitals operate 24 hours a day.
Treatment Train Supplied
The system begins with a sealed collection tank, screening, and flow equalization.
Biological treatment uses an extended-aeration activated-sludge process for stable COD and BOD removal.
Effluent passes through filtration and a chlorine/UV disinfection stage before discharge. If your site also runs this kind of duty, Chrome Chemical Wastewater Treatment system covers the cost side of the decision in more depth.
Backup disinfection and emergency bypass arrangements were included for maintenance and power-failure scenarios.
All tanks and channels are covered and vented to prevent odor and aerosol release.
Numbers from Comparable Installations
We commissioned a 35 m³/day plant for this duty in Fuyang, Anhui back in 2021. Feed COD came in around 35,000 mg/L and left at 500 mg/L — 98.6% removal. The train was pretreatment + Fenton + electrolysis + UASB + A/O.
| Location | Year | Flow | Feed COD | Treated COD | Removal |
|---|---|---|---|---|---|
| Fuyang, Anhui | 2021 | 35 m³/d | 35,000 mg/L | 500 mg/L | 98.6% |
Figures are site-measured values from commissioned plants, not modelled estimates.
Operators were trained on chemical handling, sampling, and emergency response procedures.
Installation and Commissioning
Baihuipu delivered the skid-mounted system, connected it to the hospital's sewer, and integrated power and controls.
Commissioning included biological startup, disinfection calibration, and effluent sampling.
A local third party verified that the effluent met the local medical-wastewater discharge standard.
Results
The Chengdu hospital system has operated without environmental violations since commissioning.
Maintenance is limited to routine cleaning, chemical top-up, and periodic sampling.
Baihuipu's medical wastewater package is now offered to other hospitals and clinics in China.
Integrated Treatment Strategies
The same selection criteria reappear in activated carbon production wastewater, which is worth opening alongside this one. Most facilities do not run a single clean stream, and a shared equalisation and biological stage is usually the economical answer once the streams are chemically compatible.
Why Choose Baihuipu as Your Manufacturer
Picking a supplier for this kind of plant is mostly about who carries the risk when something goes wrong. We have built this equipment for more than twenty years, and we are the ones who fabricated it, programmed the controls and will still answer the phone three years from now.
Manufacturing Base in Guangdong
Owned production lines mean we control tolerances, materials and delivery. Standard modular units and bespoke skids are both built by our own people, so schedule commitments are ours to keep.
20+ Years Across Dozens of Industries
Experience matters most when your waste stream behaves nothing like the textbook example. We have dealt with toxic organics, heavy metals, extreme salinity and refractory COD in food processing, chemical manufacturing, electroplating, mining and municipal projects.
Complete Units and Turnkey Plants
Whether you need a single package unit or a turnkey installation with civil works, we deliver the entire treatment scheme. Our engineering team covers process, mechanical, electrical and automation so one party owns the outcome.
Spare Parts and After-Sales Support
We carry membranes, pumps, blowers, diffusers and instruments for every system we supply. Remote support through the PLC is standard on most builds, and on-site service covers commissioning, training and urgent callouts.
Twenty-Plus Export Markets
We have shipped to the United States, Canada, Russia, Indonesia, India, Nigeria and Vietnam among others. Crating, export documentation and certificates are handled in-house, which keeps customs surprises to a minimum.

Frequently Asked Questions
How do you handle sludge from this process?
Sludge handling is where most budgets quietly blow out. We size dewatering against realistic solids production, and we usually recommend a filter press for this duty. The disposal route — landfill, incineration, or a licensed contractor — should be confirmed before commissioning.
Which discharge standard will the treated water meet?
We design against whatever consent applies at your boundary — GB 8978, local sewer limits, or a ZLD target with no liquid discharge at all. The design basis is agreed in writing before fabrication, so there is no argument later about what "compliant" meant.
How long does a hospital medical China system take to deliver?
Standard units ship in about 9 to 12 weeks. Custom trains with treatment train supplied included run longer — plan for 15 to 25 weeks once detailed engineering starts. Site installation and wet commissioning add another few weeks.
How much operator attention does the system need day to day?
Automatic control handles dosing, backwash and level control. Realistically your team spends time on chemical top-up, sample testing and sludge handling — maybe one to two hours per shift on hospital medical China duty, less if you opt for remote monitoring.
What treatment capacity do you normally design for hospital medical China?
Skid-mounted units cover roughly 10 to 1067 m³/day depending on the duty, and parallel trains extend that further. We size against your actual peak hour flow rather than the daily average, because equalisation rarely absorbs the whole spike.
