超高层建筑中水回用设计探讨

超高层建筑中水回用意义重大,在做中水平衡时,可按设计最高日用水量及相应的排水量进行水量平衡核算;建议适当增大调节池的有效容积以提高中水利用率;对于以优质杂排水为中水原水的中水工艺选择时,须考虑生物处理单元或活性炭吸附单元;建议采用流量式雨水初期弃流装置,并在弃流装置前设置筒形过滤器去除雨水中的较大颗粒污染物。进而促进中水回用的产业化发展,达到节约用水的目的。

DISCUSSION ON RECLAIMED WATER UTILIZATION IN SUPERHIGH BUILDING

Utilization of reclaimed water in superhigh building has great significance. During design of reclaimed water balance, water balance can be calculated according to the maximum design daily water consumption and related water drainage; it is suggested to appropriately enlarge the effective volume of the balance tank so as to improve utilization ratio of reclaimed water; during selection of water reclaiming technique for superior miscellaneous water drainage, biological treatment unit or active carbon absorption unit must be considered; it is suggested to use flow-type initial rainwater discharge device on which upstream drum filter shall be mounted to remove large particulate pollutant in rainwater, so as to promote industrial development of reclaimed water utilization and to reach the water saving purpose.
