普遍(bian)采(cai)用(yong)的(de)重力排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)大多只能順利通(tong)過濃度較低、雜(za)質很少的(de)液體，一(yi)(yi)(yi)旦(dan)泔(gan)水(shui)(shui)(shui)(shui)(shui)、淤泥、塑料(liao)袋、碎石(shi)、磚塊等雜(za)物混(hun)為(wei)一(yi)(yi)(yi)體，極易堵塞(sai)管道。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)應符合通(tong)過真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)設(she)備(bei)使(shi)排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)管道內(nei)產(chan)生一(yi)(yi)(yi)定程度的(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)負(fu)壓(ya)，利用(yong)空(kong)(kong)(kong)(kong)(kong)氣壓(ya)差，將真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)界面單元內(nei)的(de)污、廢水(shui)(shui)(shui)(shui)(shui)快速推入排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)管道的(de)排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)。真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)，是(shi)對重力排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)的(de)一(yi)(yi)(yi)種有(you)益補充，是(shi)有(you)別于重力排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)的(de)一(yi)(yi)(yi)種新型排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)，利用(yong)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)設(she)備(bei)，使(shi)管道內(nei)產(chan)生一(yi)(yi)(yi)定的(de)真(zhen)(zhen)空(kong)(kong)(kong)(kong)(kong)度，利用(yong)空(kong)(kong)(kong)(kong)(kong)氣作為(wei)輸送介質，從(cong)而實現污水(shui)(shui)(shui)(shui)(shui)收(shou)集的(de)一(yi)(yi)(yi)種排(pai)(pai)(pai)水(shui)(shui)(shui)(shui)(shui)方式。

室(shi)(shi)內(nei)系(xi)(xi)統的(de)(de)工(gong)作(zuo)原理是當污(wu)水(shui)(shui)(shui)(shui)達(da)到一定水(shui)(shui)(shui)(shui)量時，垃圾滲濾(lv)液(ye)真(zhen)(zhen)(zhen)(zhen)空(kong)排水(shui)(shui)(shui)(shui)，真(zhen)(zhen)(zhen)(zhen)空(kong)控制(zhi)(zhi)閥會自動開啟。真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)站中的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)使(shi)管道內(nei)維(wei)持著0.6bar的(de)(de)負壓，污(wu)水(shui)(shui)(shui)(shui)將以(yi)4m/s的(de)(de)速(su)度通過真(zhen)(zhen)(zhen)(zhen)空(kong)管道進入真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)站中的(de)(de)真(zhen)(zhen)(zhen)(zhen)空(kong)罐。我們(men)的(de)(de)系(xi)(xi)統主要分(fen)為(wei)室(shi)(shi)內(nei)和室(shi)(shi)外(wai)兩個系(xi)(xi)統：室(shi)(shi)內(nei)系(xi)(xi)統，由真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)站（真(zhen)(zhen)(zhen)(zhen)空(kong)泵(beng)(beng)、污(wu)水(shui)(shui)(shui)(shui)泵(beng)(beng)及(ji)真(zhen)(zhen)(zhen)(zhen)空(kong)罐）、真(zhen)(zhen)(zhen)(zhen)空(kong)座(zuo)便(bian)器(qi)、控制(zhi)(zhi)裝(zhuang)置（管道及(ji)真(zhen)(zhen)(zhen)(zhen)空(kong)控制(zhi)(zhi)閥）組(zu)成。室(shi)(shi)內(nei)系(xi)(xi)統的(de)(de)工(gong)作(zuo)原理是當污(wu)水(shui)(shui)(shui)(shui)達(da)到一定水(shui)(shui)(shui)(shui)量時，真(zhen)(zhen)(zhen)(zhen)空(kong)控制(zhi)(zhi)閥會自動開啟。使(shi)用真(zhen)(zhen)(zhen)(zhen)空(kong)的(de)(de)原理是一種依(yi)靠氣(qi)壓差產生挾裹(guo)污(wu)水(shui)(shui)(shui)(shui)的(de)(de)高(gao)速(su)氣(qi)流，并把(ba)污(wu)水(shui)(shui)(shui)(shui)從器(qi)具(ju)中取走的(de)(de)排水(shui)(shui)(shui)(shui)系(xi)(xi)統，可以(yi)簡單地解決(jue)排水(shui)(shui)(shui)(shui)沼坡，使(shi)污(wu)水(shui)(shui)(shui)(shui)可以(yi)任意地提(ti)升，沒有外(wai)溢，不會污(wu)染地下水(shui)(shui)(shui)(shui)，環(huan)保程度高(gao)。

使用(yong)真空的原(yuan)理是(shi)一種依(yi)靠氣(qi)壓差產生挾(xie)裹污(wu)(wu)水(shui)(shui)的高速氣(qi)流，并把污(wu)(wu)水(shui)(shui)從器具中取(qu)走(zou)的排水(shui)(shui)系(xi)統(tong)，可(ke)以(yi)簡單地(di)解決排水(shui)(shui)沼坡，使污(wu)(wu)水(shui)(shui)可(ke)以(yi)任意地(di)提升，沒有外(wai)溢，不會污(wu)(wu)染地(di)下(xia)水(shui)(shui)，環保(bao)程度高。城市遭遇大(da)雨，排水(shui)(shui)系(xi)統(tong)經常癱瘓，很(hen)大(da)原(yuan)因(yin)就在于此。即便是(shi)在深達8米(mi)的地(di)方，75毫米(mi)直徑內(nei)的固(gu)體雜物(wu)、惡(e)臭有毒的氣(qi)體都能隨著真空管道被吸走(zou)。普遍采用(yong)的重力排水(shui)(shui)系(xi)統(tong)大(da)多只能順利通過濃(nong)度較低、雜質很(hen)少(shao)的液體，一旦泔水(shui)(shui)、淤泥、塑料袋、碎石、磚(zhuan)塊等(deng)雜物(wu)混為一體，極易堵塞管道。
