【正文】 water, and used as building miscellaneous water and miscellaneous water city, such as toilet flushing, road cleaning, urban greening, vehicle washing, building construction, fire control and other miscellaneous, so as to replace the same amount of water, this is equivalent to increase the city39。s water supply.7 make full use of rainwater Collected rainwater utilization is the rain, after certain facilities and medicament treatment, get conform to the process of some water quality indicators of water reuse. Similar Yu Zhongshui, treated as a kind of can make use of rain water, can be used for toilet flushing, urban greening, landscaping and other adapted to water in the water quality standards in the use of of the buildings are now in our country will be on the roof rainwater directly discharged into municipal rainwater pipeline, which not only increased the municipal rainwater pipeline capacity, increase the diameter, increase the cost, at the same time is also a kind of waste of water resources. Building general structure is of collecting rainwater, by catheter of the roof rainwater is located in underground rain sand basin, the deposition of rainwater flow reservoir, the water pump to the miscellaneous water reservoir, after chlorine disinfection, to the water in the pipe system. To solve the problem of dust and acid rain, the rain are the first two minutes of rainwater squeamishness.8 the drinking water system and fire water system respectively set up separately In the appropriate to the drinking water system in the design of highrise building water supply and fire fighting water supply system are set up separately, and because two different feed system for water pressure requirements. According to the rules: the drinking water system according to hydrostatic pressure no greater than 300 kpa to 400 kpa partitions, fire water supply system by the hydrostatic pressure no greater than 800 kpa partition is according to the requirements of fire fighting water pressure value partition, will make the life water supply pipeline overpressure caused by excess water supply problems。 If all the year round with a pressure reducing valve depression throttling, and certainly will cause energy waste。 If according to the requirements of domestic water pressure partition, it will be relatively increase the number of pump unit. So, no matter from energysaving throttling, or save engineering investment, convenient operation and management of various point of view, should be separate life, fire water system Settings. It is easy to reasonably determine the pressure value in the vertical division of water supply system, avoid to cause energy waste.
