Among them, there are three core subsystems

1、 Centralized water supply system in hospital

The hospital centralized water supply system mainly includes medical pure water centralized supply system and acid oxidation potential water centralized supply system, which basically covers all kinds of medical water in a comprehensive hospital.

2、 Reclaimed water utilization system in hospital

The reclaimed water utilization system in hospital mainly includes rainwater collection and treatment system and reclaimed water treatment system, which can effectively improve the utilization rate of comprehensive water resources in hospital and save a lot of resources.

3、 Advanced treatment system of hospital sewage

The medical sewage treatment system mainly adopts two kinds of treatment processes, traditional treatment process and MBR advanced treatment process. The treatment scope covers the clinical, domestic and fecal sewage discharged from outpatient, ward, operating room, various inspection rooms, pathological anatomy room, radiation room, laundry room, mortuary and other sewage discharged from medical institutions when mixed with the above sewage.

Five design principles should be followed in the design of hospital centralized water supply system

1, advanced nature: adopt advanced technology that is used internationally or domestically.

2. Maturity: Based on the principle of applicability, using mature or engineering tested advanced technology.

3. Standardization: the use of standardized design and standardized products.

4. Security: including the security of the system itself and the security of information transmission.

5. Design service life: provide brand new and first-class quality materials and equipment, and design long service life, suitable for 24 hours of continuous work every day.

On the basis of these five principles, through the treatment process with membrane separation as the core technology "pretreatment system → reverse osmosis system → post-treatment system → circulation distribution system", the "centralized water production and quality water supply" can be realized, and the following requirements can be achieved:

1. Low energy consumption and low operation cost.

2. The equipment selection is reasonable, reliable, advanced, efficient and energy-saving, and the investment cost and maintenance cost can be reduced as much as possible.

3. For safe operation, the system considers emergency treatment measures to ensure water supply for a certain time and key departments under abnormal conditions.

4. Fully consider the comprehensive utilization of concentrated water to improve the utilization rate of water resources.

5. The materials and equipment provided are brand new and of first-class quality, and are designed for a long service life, suitable for 24 hours of continuous work every day.

6. The system equipment is easy to inspect, clean, lubricate and maintain.

The design of medical sewage treatment system should follow six principles

1. Whole process control principle: control the whole process of hospital sewage generation, treatment and discharge.

2. Reduction principle: strict hospital internal health management system, strict control and separation at the source of sewage and sewage, domestic sewage in the hospital and ward sewage were collected separately, that is, source control, separation of clean water and sewage.

3. Principle of on-site treatment: in order to prevent the pollution and harm in the process of hospital sewage transportation, on-site treatment must be carried out in the hospital.

4. Classification guiding principle: according to the nature, scale, discharge direction and regional differences of hospital sewage, the hospital sewage treatment should be classified and guided.

5. The principle of combining standard and risk control: comprehensively consider the basic requirements of standard discharge of general hospitals and infectious disease hospitals, strengthen the awareness of risk control, and improve the ability to deal with sudden time from the aspects of process technology, engineering construction and supervision and management.

6. Ecological safety principle: effectively remove the toxic and harmful substances in the sewage, reduce the generation of disinfection by-products in the disinfection process and control the excessive residual chlorine in the effluent, so as to protect the ecological environment.

7. On the basis of the six basic principles, through the traditional treatment process and MBR advanced treatment process, the medical sewage can reach the discharge standard of "discharge standard of water pollutants for medical institutions" GB 18466-2005.
