Design On Antifouling And Energy Saving Design Of Hospital Building Water System

The data show that the water has been polluted in different degrees in the building water supply system.With the rapid growth of population and the acceleration of urbanization,the consumption of water resources has increased dramatically.This caused the global water crisis,such as water shortages and water quality deterioration,which poses a serious threat to human health and biodiversity.In China,it is urgent to ensure the safety of drinking water.Environmental protection is an eternal theme of social life in the future,for each water supply and drainage design of building workers,the environmental problem is not the simple sewage treatment discharge standards so simple,it runs through every detail in the design.Most of the new materials,new equipment and new technology of building water supply and drainage are closely related to the requirements of environmental protection.It is our duty to make full use of these new technologies to realize the environmental protection design of building water supply and drainage.The design of building water supply and drainage should be based on the principle of energy saving and emission reduction,so as to control the source.At the same time,it also shoulders the responsibility of saving resources,energy and protecting the environment.Taking hospital buildings as an example,this paper studies two main aspects of building water supply and drainage design,namely: prevention of water pollution and water saving and energy conservation,systematically introduces the water supply and drainage design of the building,and measures to prevent water pollution.Water saving and energy saving issues.In the prevention of water pollution,the water supply system and the drinking water system are dissected,and then the corresponding measures taken to prevent water pollution in the two systems are highlighted.For the water supply system,a backflow preventer is installed at the inlet pipe to prevent the water inside the building from flowing back into the municipal pipe to ensure the water quality.The municipal low water supply in the lower area of the project effectively utilizes the municipal water pressure and saves energy.The high area adopts frequency conversion speed regulation water supply and installs ultraviolet sterilizer on the frequency conversion constant pressure water supply living water supply equipment for disinfection,killing microorganisms harmful to the human body such as bacteria and viruses in water.For the drainage system and the fire protection system,it does not constitute water pollution.Therefore,for drainage systems and fire protection systems,this paper focuses on the design and research to prevent water pollution.For the drainage system,improper design of the septic tank may cause leakage of groundwater.Therefore,the project uses a new bio-filler-reinforced FRP septic tank,and the antiseepage performance is much higher than that of traditional brick and steel mixed manure.The pool and septic tank volume has been reduced by more than 2/3,and the treatment efficiency has been improved.In addition,the sewage in hospitals usually has many pathogens,radioactive substances,and chemical substances.If the sewage is leaked,it will cause great harm.Therefore,a sewage treatment station is set up in this project to treat the potential sick sewage discharged from the hospital.Compared with the comparison of three kinds of sewage treatment processes,using gridadjustment tank-A/O-MBR membrane process-ozone disinfection,the dosage of ozone is 1 mg/L,which can achieve stable treatment effect and solve the stinky question.For the fire protection system,the early fire water tank is easy to use with the domestic water tank,which will easily cause pollution of drinking water.Therefore,in this design,the fire water tank and the living water tank are separately arranged to avoid the pollution of the fire water tank to the living water tank.In terms of water saving and energy saving,it mainly focuses on the cold-water system and hot water system and analyzes the waste phenomenon of tap water in the overpressure outflow.Reasonably installing the pressure reducing orifice plate avoids the waste of water resources,and the comprehensive water saving rate reaches 30%.Above,the ceramic core faucet is installed at the same time,and the total water saving rate is more than 50%.Therefore,overpressure outflow control and water-saving faucet installation can greatly increase the water saving rate,which is a means of water conservation that should be paid attention to by architectural design units.The thickness of the thermal insulation system of the hospital is 35 mm.The main pipe circulation and non-circulation mode.
