1 Overview of hospital building water supply and drainage system design
Modern hospital building water supply and drainage system will have a direct impact on the smooth progress of the hospital work, change the social image of the hospital, further improve the quality of hospital services, and to create a good medical environment, is the goal of the hospital building water supply and drainage design. Now, the medical facilities of the hospitals are gradually improved, the amount of money invested is also increasing year by year, the requirements of supporting the smooth operation of the water supply and drainage system to reduce the emergence of problems, and lay a good foundation for the operation of the departments and equipment.
2 Hospital building water supply and drainage design requirements
2.1 Water supply system. Water supply system is a necessary system in the entire hospital structure, its service object in addition to daily water, including the water of medical equipment, and different instruments on water quality, water temperature, water pressure and other special requirements, sometimes need to be appropriate to increase or decrease the pressure or special treatment. Take the water used in the hospital's preparation room, pathology department and central supply room as an example, these departments use pure water, which has high requirements for water quantity and quality, and different water areas also have different requirements for water. In order to scientifically utilize water resources and enhance the use function, many hospitals have already carried out comprehensive alterations to the water supply system, established pure water systems, and used the centralized centralized preparation and sub-regime water supply system mode, i.e., they know the water consumption and standards of each department in advance, organize them, and provide water according to the use requirements of different departments. This management mode has the characteristics of centralized management, saving equipment and space, reducing the cost investment in equipment and space, and ensuring the quality of the hospital's water supply.
2.2 Sewage and wastewater system. The sewage and wastewater system of the hospital mainly collects and treats the domestic sewage and medical wastewater produced by each department. Hospitals produce a large amount of wastewater every day, certain departments will also produce wastewater containing a large number of pathogens, heavy metals, chemicals and radioactive substances, if not treated in a timely manner, will increase the environmental risk and bring environmental hazards, so the sewage system needs to be based on the amount of wastewater discharged from various departments and the amount of special substance content, the design of the system, with the premise of piping structure, scientific arrangement of the distribution pipeline and treatment equipment.
2.3 fire sprinkler system. Fire sprinkler system is distributed throughout the hospital's building structure, its sensitivity is the key to ensure the safety of the hospital, for the normal operation of the hospital's work to provide protection. That is, its system design should be consistent with the structure of the whole building, scientific arrangement of pipes and nozzles, so as to automatically, quickly and timely control of fire extinguishing.
3 Optimization of hospital building water supply and drainage design
Because of the special nature of hospital work, a large number of complex systems will be used, the design has high requirements, and the water supply and drainage system in addition to meet the water safety of various departments, but also to be reasonably designed to ensure that the work of various departments is carried out smoothly, and optimize the treatment of wastewater generated by the hospital.
3.1 Optimization of water supply quality. The optimization of water supply water quality is mainly for maternity wards, operating rooms, ophthalmology and other departments, which need to purify and disinfect the water, use purification equipment to eliminate pathogenic sources, and ensure that the water supply is dust-free and sterile. At the same time, it is also necessary to regularly check the water supply pipeline and maintain the purification equipment to ensure that the water quality meets the standard. Hospital preparations need to use distilled water to make all kinds of pharmaceuticals, in this regard, the need to use a special water supply system, placed in certain areas of the pressurized equipment, or according to the requirements of the laboratory, the rational design of the water supply pipeline, set up a detection system, timely detection of operational problems and solve them.
3.2 Optimization of water supply and drainage equipment. Hospital patient flow, mobility, complex personnel, easy to cross-infection, in order to reduce the risk of infection, open the water supply switch to try to avoid touching with the hand, you can use the knee, elbow, foot pedal and other ways to meet the water hygiene and safety. However, the foot-operated water supply method must be well protected against leakage, so as to avoid excessive accumulation of water on the ground and inadvertent slipping of personnel. Use of hot and cold water faucets in the department, you can maintain a constant temperature of the water, and the use of induction electromagnetic control. The water spout has special requirements for the department, such as preparation room, laboratory, need to be installed according to its specific requirements. Wastewater generated by the hospital can only be re-emitted after treatment, especially the wastewater generated by the hospital laboratory, testing room, may corrode the pipeline or other processing equipment, so the hospital should be preferred drainage pipe material, and special anti-corrosion treatment, to avoid rust, rupture of the pipeline, and leakage of hazardous substances and other problems.
3.3 Optimization of pipeline design. The optimization of pipeline design includes two aspects, one is the water supply pipeline, and the other is the drainage pipeline. First of all, the water supply pipeline has functionality at the same time, but also to be as beautiful as possible, especially some outpatient and medical departments of the water supply pipe, because of its special use of the function of the overall confusion of the water supply pipeline arrangement, the pipeline is exposed, both unattractive and unhygienic. In this regard, the designers need to combine the specific conditions of the hospital building structure, make full use of different structural forms, comprehensive arrangement of the water supply system pipeline, optimize the design of water supply pipeline. Secondly, in view of the complexity of the quality of sewage water, wastewater containing different hazardous substances to establish a special wastewater collection pipeline, unified collection and targeted treatment. For example, test waste, chemical pollutants, etc., need to be discharged in a classified manner, strict sterilization and then incineration.
The wastewater generated by the stomatology department contains heavy metals, which should be treated with chemical precipitation or ion exchange before discharge. Hospitals, whether from the point of view of environmental protection or safety considerations, need to carry out comprehensive treatment of wastewater, strengthen testing and supervision, remove harmful substances in the wastewater, to ensure that the treatment process meets the standards, and the treated wastewater meets the discharge standards.
3.4 Energy saving optimization. In the phenomenon of water resources waste, in this regard, the hospital is required to innovate the water supply, according to the amount of existing water supply in the hospital, design a new form of water supply, and do a good job of water conservation planning, in order to improve the utilization rate of water, so as to achieve the purpose of water conservation. At the same time, the hospital should introduce new water supply equipment, adopt new water supply technology, optimize the water supply and drainage of each department in the hospital, and reduce water consumption.
4 Conclusion
In summary, the design optimization of modern hospital water supply and drainage system, need to consider a number of factors, a comprehensive analysis, to ensure that the water supply is hygienic and reliable, safe and environmentally friendly drainage, for the special nature of the medical work and the different functions of the department of the use of the requirements of a comprehensive optimization of the design, not only to meet the departmental requirements for water but also to meet the standards of sewage discharge, to ensure that the hospital's various work The hospital's work to ensure the smooth running of the hospital.
