為人居及工業區的(de)(de)(de)分質排水(shui)(shui)及智(zhi)能化處理提供有效手段(duan)由于(yu)負壓(ya)輸送管(guan)(guan)(guan)(guan)道管(guan)(guan)(guan)(guan)徑遠小于(yu)重力(li)流管(guan)(guan)(guan)(guan)道，而且不需要(yao)以逐步增(zeng)加(jia)埋深形成坡度，所以管(guan)(guan)(guan)(guan)道敷設(she)和施工變得更(geng)加(jia)簡單。真(zhen)空(kong)管(guan)(guan)(guan)(guan)道內(nei)的(de)(de)(de)排水(shui)(shui)水(shui)(shui)流速(su)度可達(da)到3-6米(mi)/秒，而普(pu)通(tong)排水(shui)(shui)系(xi)統(tong)(tong)的(de)(de)(de)排水(shui)(shui)速(su)度頂多(duo)達(da)到1米(mi)/秒。假設(she)一(yi)套實用面積(ji)100平方(fang)米(mi)、樓(lou)層高度為3米(mi)的(de)(de)(de)住房(fang)完全被水(shui)(shui)淹(yan)沒，用一(yi)排水(shui)(shui)能力(li)為2立方(fang)米(mi)/秒的(de)(de)(de)真(zhen)空(kong)高速(su)排水(shui)(shui)系(xi)統(tong)(tong)僅需要(yao)2.5分鐘就能將這(zhe)300立方(fang)積(ji)水(shui)(shui)排走。真(zhen)空(kong)壓(ya)力(li)本身具有清(qing)洗疏通(tong)管(guan)(guan)(guan)(guan)道的(de)(de)(de)功能。為防(fang)止可能發生的(de)(de)(de)固體(ti)過大導致(zhi)管(guan)(guan)(guan)(guan)道阻(zu)塞現象，高速(su)真(zhen)空(kong)排水(shui)(shui)系(xi)統(tong)(tong)還可在機(ji)組的(de)(de)(de)入口處加(jia)裝切割機(ji)，將固體(ti)顆粒解(jie)體(ti)剁碎，同(tong)時(shi)保護管(guan)(guan)(guan)(guan)道。

真(zhen)空(kong)(kong)(kong)(kong)(kong)泵站(zhan)中(zhong)(zhong)的(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)泵使管(guan)道(dao)(dao)內維持(chi)著0.6bar的(de)負(fu)(fu)壓(ya)(ya)，垃圾滲(shen)濾液真(zhen)空(kong)(kong)(kong)(kong)(kong)排(pai)水(shui)(shui)，污水(shui)(shui)將(jiang)以4m/s的(de)速度(du)通過真(zhen)空(kong)(kong)(kong)(kong)(kong)管(guan)道(dao)(dao)進入真(zhen)空(kong)(kong)(kong)(kong)(kong)泵站(zhan)中(zhong)(zhong)的(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)罐(guan)。真(zhen)空(kong)(kong)(kong)(kong)(kong)排(pai)水(shui)(shui)避免了傳統(tong)的(de)重力向下的(de)排(pai)水(shui)(shui)局(ju)限性，所(suo)以管(guan)道(dao)(dao)布置具有任意性。負(fu)(fu)壓(ya)(ya)排(pai)水(shui)(shui)系統(tong)不像(xiang)重力排(pai)水(shui)(shui)系統(tong)那樣易受建筑結構、環境、地(di)勢(shi)等(deng)條件的(de)限制，能較(jiao)靈(ling)活地(di)適用(yong)于各類(lei)建筑、城市與(yu)鄉(xiang)村排(pai)水(shui)(shui)及工業園區排(pai)水(shui)(shui)。真(zhen)空(kong)(kong)(kong)(kong)(kong)排(pai)水(shui)(shui)系統(tong)應符合(he)通過真(zhen)空(kong)(kong)(kong)(kong)(kong)設備(bei)使排(pai)水(shui)(shui)管(guan)道(dao)(dao)內產生一(yi)定程度(du)的(de)真(zhen)空(kong)(kong)(kong)(kong)(kong)負(fu)(fu)壓(ya)(ya)，利用(yong)空(kong)(kong)(kong)(kong)(kong)氣壓(ya)(ya)差，將(jiang)真(zhen)空(kong)(kong)(kong)(kong)(kong)界面單元內的(de)污、廢水(shui)(shui)快(kuai)速推入排(pai)水(shui)(shui)管(guan)道(dao)(dao)的(de)排(pai)水(shui)(shui)系統(tong)。

在設(she)潛(qian)水(shui)(shui)排水(shui)(shui)泵 提升(sheng)至室(shi)外，但地下廣場面積很(hen)大(da)，集(ji)水(shui)(shui)池(chi)布置點分散，引向室(shi)外的(de)排出口多，若使用傳統(tong)重力排水(shui)(shui)，氣(qi)味將(jiang)是一(yi)個很(hen)難根本解決的(de)問題并且眾多的(de)透(tou)氣(qi)管延出屋頂，影響(xiang)整個建筑的(de)美觀(guan)。為了(le)保(bao)證真(zhen)(zhen)空(kong)(kong)管道的(de)承受力，一(yi)般(ban)采用抗壓能力1.0兆帕(pa)，HD－PE/SDR11標準的(de)材質(zhi)。真(zhen)(zhen)空(kong)(kong)泵為間(jian)歇性運作(zuo)，在管道內負壓低于(yu)0.4bar時才(cai)由自動控(kong)制(zhi)柜控(kong)制(zhi)開啟，以(yi)(yi)維持(chi)一(yi)定的(de)真(zhen)(zhen)空(kong)(kong)度。真(zhen)(zhen)空(kong)(kong)泵平(ping)均每(mei)(mei)天(tian)工作(zuo)時間(jian)為4小(xiao)時。真(zhen)(zhen)空(kong)(kong)罐將(jiang)污水(shui)(shui)進行收(shou)集(ji)，當(dang)達到(dao)一(yi)定液位(wei)后排放到(dao)市政下水(shui)(shui)道中。室(shi)內系統(tong)的(de)設(she)備要求，洗(xi)(xi)臉(lian)盆、小(xiao)便(bian)斗(dou)、浴缸等(deng)可(ke)采用一(yi) 般(ban)通用潔具，根據(ju)水(shui)(shui)量的(de)不同，可(ke)以(yi)(yi)有多個潔具連接一(yi)個真(zhen)(zhen)空(kong)(kong)控(kong)制(zhi)閥；座便(bian)器必須由外國公司提供的(de)特(te)殊真(zhen)(zhen)空(kong)(kong)座便(bian)器，它保(bao)證了(le)每(mei)(mei)次沖(chong)洗(xi)(xi)只要1升(sheng)的(de)水(shui)(shui)，并將(jiang)真(zhen)(zhen)空(kong)(kong)控(kong)制(zhi)閥整合在座便(bian)器內，將(jiang)整個系統(tong)變(bian)為一(yi)種由空(kong)(kong)氣(qi)作(zuo)為傳輸介質(zhi)的(de)負壓密閉狀態(tai)之中。
