采用(yong)常用(yong)的排(pai)水(shui)(shui)(shui)(shui)系統(tong)，則至(zhi)少需要85分(fen)(fen)鐘(zhong)(zhong)(zhong)才可(ke)能將(jiang)這些(xie)水(shui)(shui)(shui)(shui)排(pai)凈，時間相(xiang)差50分(fen)(fen)鐘(zhong)(zhong)(zhong)。但若(ruo)急需排(pai)水(shui)(shui)(shui)(shui)搶救生(sheng)命(ming)和財產，這50分(fen)(fen)鐘(zhong)(zhong)(zhong)就顯(xian)得彌(mi)足珍貴。真(zhen)空(kong)(kong)(kong)排(pai)水(shui)(shui)(shui)(shui)系統(tong)，是(shi)對重力(li)排(pai)水(shui)(shui)(shui)(shui)系統(tong)的一(yi)(yi)(yi)種有(you)益補充，是(shi)有(you)別于重力(li)排(pai)水(shui)(shui)(shui)(shui)系統(tong)的一(yi)(yi)(yi)種新(xin)型排(pai)水(shui)(shui)(shui)(shui)系統(tong)，利用(yong)真(zhen)空(kong)(kong)(kong)設備，使管(guan)道內產生(sheng)一(yi)(yi)(yi)定(ding)的真(zhen)空(kong)(kong)(kong)度，利用(yong)空(kong)(kong)(kong)氣作(zuo)為(wei)輸送介質(zhi)(zhi)，從而實現污水(shui)(shui)(shui)(shui)收集(ji)(ji)的一(yi)(yi)(yi)種排(pai)水(shui)(shui)(shui)(shui)方式。為(wei)了保證真(zhen)空(kong)(kong)(kong)管(guan)道的承受力(li)，一(yi)(yi)(yi)般(ban)采用(yong)抗壓(ya)能力(li)1.0兆帕，HD－PE/SDR11標(biao)準(zhun)的材質(zhi)(zhi)。真(zhen)空(kong)(kong)(kong)泵為(wei)間歇性(xing)運(yun)作(zuo)，在管(guan)道內負壓(ya)低于0.4bar時才由自動控(kong)制柜控(kong)制開啟，以維持一(yi)(yi)(yi)定(ding)的真(zhen)空(kong)(kong)(kong)度。真(zhen)空(kong)(kong)(kong)泵平均每天工作(zuo)時間為(wei)4小時。真(zhen)空(kong)(kong)(kong)罐將(jiang)污水(shui)(shui)(shui)(shui)進行收集(ji)(ji)，當達(da)到一(yi)(yi)(yi)定(ding)液位后排(pai)放到市政下水(shui)(shui)(shui)(shui)道中(zhong)。

為(wei)人居及工(gong)業(ye)區(qu)的(de)分質排(pai)水(shui)(shui)及智(zhi)能(neng)化(hua)處(chu)理提供有效手(shou)段(duan)由于負壓輸送管(guan)道管(guan)徑遠小(xiao)于重(zhong)(zhong)力流(liu)管(guan)道，而且不(bu)需要以(yi)逐(zhu)步增加(jia)埋(mai)深形成坡度，所以(yi)管(guan)道敷設(she)和(he)施(shi)(shi)工(gong)變得(de)更(geng)加(jia)簡單。室內系統(tong)(tong)的(de)工(gong)作原理是當污水(shui)(shui)達到一(yi)定水(shui)(shui)量時，真空(kong)控制閥會自動(dong)開(kai)啟。真空(kong)泵站中(zhong)(zhong)的(de)真空(kong)泵使管(guan)道內維(wei)持著0.6bar的(de)負壓，污水(shui)(shui)將(jiang)以(yi)4m/s的(de)速(su)度通過真空(kong)管(guan)道進入真空(kong)泵站中(zhong)(zhong)的(de)真空(kong)罐(guan)。真空(kong)排(pai)水(shui)(shui)系統(tong)(tong)可用(yong)于替代傳統(tong)(tong)的(de)重(zhong)(zhong)力排(pai)水(shui)(shui)系統(tong)(tong)，作為(wei)一(yi)種(zhong)新型(xing)的(de)排(pai)水(shui)(shui)系統(tong)(tong)能(neng)夠在實際工(gong)程(cheng)(cheng)中(zhong)(zhong)解(jie)決重(zhong)(zhong)力排(pai)水(shui)(shui)系統(tong)(tong)施(shi)(shi)工(gong)的(de)難題，其(qi)將(jiang)具(ju)有較大的(de)應用(yong)潛力、廣(guang)泛的(de)使用(yong)場合和(he)的(de)工(gong)程(cheng)(cheng)與技術經濟的(de)優勢。

在(zai)(zai)設潛(qian)水(shui)(shui)(shui)排水(shui)(shui)(shui)泵 提升至室(shi)(shi)外(wai)，養殖場真(zhen)空排水(shui)(shui)(shui)，但(dan)地下(xia)廣(guang)場面積很大(da)，集水(shui)(shui)(shui)池(chi)布(bu)置點分散(san)，引向室(shi)(shi)外(wai)的排出(chu)口多，若使用傳統重(zhong)力(li)排水(shui)(shui)(shui)，氣味將是一個(ge)很難根本解(jie)決(jue)的問題并且(qie)眾多的透氣管延出(chu)屋(wu)頂(ding)，影(ying)響(xiang)整(zheng)個(ge)建筑的美觀。真(zhen)空排水(shui)(shui)(shui)避免了傳統的重(zhong)力(li) 向下(xia)的排水(shui)(shui)(shui)局限性，所以(yi)(yi)管道(dao)布(bu)置具有任意(yi)性。我們可(ke)以(yi)(yi)看到地下(xia)室(shi)(shi)的洗(xi)臉盆及洗(xi)衣機(ji)的污(wu)水(shui)(shui)(shui)通過管道(dao)被提升再進(jin)入(ru)真(zhen)空罐(guan)。污(wu)水(shui)(shui)(shui)在(zai)(zai)真(zhen)空罐(guan)內存儲(chu)到一定(ding)水(shui)(shui)(shui)位(wei)后，污(wu)水(shui)(shui)(shui)泵會(hui)開啟，把污(wu)水(shui)(shui)(shui)排入(ru)市政管道(dao)。污(wu)水(shui)(shui)(shui)及廢水(shui)(shui)(shui)就會(hui)通過收集箱吸(xi)入(ru)真(zhen)空管道(dao)，再進(jin)入(ru)真(zhen)空泵站中的真(zhen)空罐(guan)。室(shi)(shi)外(wai)的真(zhen)空管道(dao)可(ke)以(yi)(yi)隨意(yi)繞過各種障礙物，甚至在(zai)(zai)同(tong)一溝渠(qu)內將污(wu)水(shui)(shui)(shui)管同(tong)其它(ta)管線布(bu)在(zai)(zai)同(tong)一平面。
