Research Of Northwest Civil Building Water Supply

With further speed up the progress of urbanization,urban water consumption is With further speed up the progress of urbanization,urban water consumption are increasing year by year,the current specification for design of building water supply and drainage GB50015-2003(2009 edition)",the water quota needs to be updated.To this end,the northwestern region of the three different sizes of cities: HuiNing of LanZhou,WuWei,civil construction water use for the research,research building types including hospital,hotel,hostel rooms,nursing home,kindergarten,serviced apartments,residential seven classes,survey data includes,unit nearly two years in the use of water conditions and construction the basic situation,at the same time,the status quo of water to seven types of civil construction and water law has carried on the collection and analysis,as well as the hospital in-patient department,nursing homes,hotel rooms the measured water situation of three kinds of buildings,also the amount of water on seven class building,influence factors,days,hours change coefficient and water law has carried on the statistical calculation and analysis,concrete results are as follows:The results showed: hospital inpatient 240 ~ 300 L/d,bed change coefficient is 1.62 ~ 1.96.Nursing home 65 ~ 140 L/d,the variation coefficient is 1.23 ~ 2.60.The hotel guest room 120 ~ 320 L/d,bed change coefficient is 1.12 ~ 2.42.Residential 90 ~ 155 L/d,the variation coefficient is 2.38 ~ 2.63.Kindergarten in 110 ~ 130 L/d,the variation coefficient is 1.54 ~ 1.76.Hostel l/bed,95 ~ 110 d,the variation coefficient is 2.22 ~ 2.87.Serviced apartments of 280 ~ 380 L/d,bed change coefficient is 2.12 ~ 2.34.Among them,the hospital inpatient,residential water consumption,kindergarten,serviced apartments is specification on the high side,nursing homes,hotel rooms water consumption is relatively low specification,residential coefficient changes specification on the high side,and when the hospital in-patient department,nursing homes,hotel rooms,kindergartens,hostel when coefficient changes specification is low,and provide reference for the norm revision.Research of the urban water supply pipe network water quality and water factory water quality conforms to the standard,research of building water supply water quality indicators most accord with a standard,but there are individual hospital senior secondary water supply,community residents more than tap water and secondary water supply hotel at the end of the chlorine detection index on the low side.
