高校作为城市用水大户具有一定的节水潜力。以北京师范大学为例,基于对其用水的全过程分析进行了节水方案总体设计,并针对宿舍用水情况进一步设计节水水箱进行simulink动态模拟。结果表明,水箱尺寸在105 cm×46 cm×55 cm(长×宽×高)时,水箱可取得建筑条件限制下最优节水效果,在考虑到实际用水情况对节水效果的折减率后,单套水箱约能供给下层水量195 m~3/a,全校约能节约水量12.37万m~3/a,模型验证该方案具有良好节水效果。 Colleges and universities as a large city has some water-saving potential. Taking Beijing Normal University as an example, the overall design of water saving scheme was carried out based on the whole process analysis of its water use. Simulink dynamic simulation was carried out to design a water - saving tank according to the water usage in dormitory. The results show that the optimal water saving effect can be obtained under the condition of the building condition when the size of the water tank is 105 cm × 46 cm × 55 cm (length × width × height). Taking into account the reduction of water saving effect After the single set of water tank can supply about 195 m 3 / a lower level of water, the school can save about 123,700 m 3 / a of water, the model shows that the program has a good water saving effect.
