Professional Medical Wastewater Management

Hospitals, the sacred guardians of public health, are busy saving lives and providing orderly medical services every day. While fulfilling their noble missions, they also generate a large amount of domestic wastewater. Unlike ordinary household sewage, this wastewater contains special pollutants such as pathogenic microorganisms, trace chemical residues, oil and suspended solids. Improper treatment and discharge will not only damage the ecological environment we cherish but also bring hidden dangers to public health. As a professional water treatment service provider that has been deeply rooted in the industry for decades, Shanghai Xiba is passionate about environmental protection and medical care. We address the pain points of hospital wastewater treatment with scientific processes, high-quality equipment and professional operation and maintenance, build a solid line of defense for wastewater purification in hospitals at all levels, and contribute our strength to the construction of green hospitals!

Hospital domestic sewage is a mixture of daily sewage from canteens and dormitories and a small amount of medical wastewater permeated from diagnosis and treatment areas. Its unique pollution characteristics require more meticulous and professional treatment services:

• Pathogen enrichment: Sewage may carry bacteria, viruses and other pathogenic microorganisms, which are easy to spread diseases if not thoroughly disinfected;

• Complex composition of pollutants: It includes trace chemical reagent residues from inspection departments and laboratories, a large amount of oil and food residues from canteens, as well as suspended solids discharged from toilets;

• Strict discharge requirements: It must fully comply with the "Emission Standard for Water Pollutants from Medical Institutions" (GB 18466-2005), and all core indicators must meet the standards accurately before being discharged into municipal pipelines or natural water bodies.

With years of love for water treatment technology, Shanghai Xiba has customized a "pretreatment + biochemical treatment + deep disinfection + intelligent operation and maintenance" full-process solution for the characteristics of hospital domestic sewage. Every link is carefully designed, layer by layer purification and closed-loop management and control, to ensure that the effluent water quality is stable and up to standard, and to protect the ecological environment with practical actions!

2.1Preprocessing: Intercept Impurities at the Source and Lay a Solid Foundation

The oily wastewater from the kitchen first flows into the high-efficiency oil separator, which quickly separates animal and vegetable oils and scum from the sewage. Then it merges with domestic sewage and enters the septic tank for anaerobic biological degradation. The supernatant of the septic tank enters the grid equipment, which accurately intercepts large-particle suspended solids such as cloth strips, plastic fragments and food residues, avoiding blockage of pipelines and subsequent treatment equipment, and laying a solid foundation for the follow-up deep treatment.

2.2  Biochemical Treatment: Core Purification, Efficient Decontamination

The pretreated sewage enters the biochemical reaction system, which is the core link of sewage purification. We adopt mature and stable treatment processes and customize microbial flora. Through the metabolism of microorganisms, we efficiently decompose organic matter in sewage, degrade pollutants, and initially kill some pathogenic microorganisms, greatly reducing the pollution load of sewage. Compared with traditional processes, the purification efficiency is improved by more than 30%, and the effluent quality is stable and reliable.

2.3  Deep Disinfection + Advanced Treatment: Build the Last Line of Defense and Ensure Compliance

After biochemical treatment, the sewage first undergoes advanced treatment to further remove residual suspended solids and chroma, making the water quality clearer. Then it enters the automatic disinfection system, using efficient and safe disinfection technology to completely kill pathogenic microorganisms in the sewage and eliminate the risk of transmission. After treatment, the sewage must pass the detection of online water quality monitoring equipment. Only when all core indicators such as COD, BOD and fecal coliform meet the regulatory standards can it be discharged in compliance.

• Strong technical strength: Deeply engaged in the water treatment industry for many years, we have a mature hospital sewage treatment process system. We can customize exclusive solutions according to the scale of the hospital and the amount of sewage discharge to meet the treatment needs of different scenarios;

• Guaranteed equipment quality: Adopt high-quality and environmentally friendly water treatment equipment with stable performance, convenient operation and maintenance, and strong resistance to load impact, effectively reducing equipment failure rate and long-term operation and maintenance costs;

• Full-cycle operation and maintenance services: Equipped with a professional operation and maintenance team, we provide full-cycle services such as equipment installation and commissioning, regular inspections, index monitoring and fault maintenance. We keep abreast of the sewage treatment effect in real time, so that hospitals can be assured and at ease;

• Compliance and accurate compliance: Strictly comply with national relevant emission standards, implement standardized treatment throughout the process, ensure stable and qualified effluent indicators, help hospitals successfully pass environmental protection acceptance, and practice the concept of green development.

Hospital sewage treatment is not only a practice of environmental responsibility but also an important guarantee for public health and safety. Shanghai Xiba Water Treatment has always adhered to the concept of "professional pollution control and ecological protection". With advanced technology, high-quality services and reliable quality, we are passionate about providing efficient, compliant and worry-free domestic sewage treatment solutions for hospitals at all levels. We are willing to work with hospitals to achieve the coordinated development of environmental protection and medical treatment, jointly guard a clear water and blue sky, and build a green, healthy and warm medical ecological environment!
