原理簡介：
來水(shui)(shui)(shui)(shui)由(you)進水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)送入(ru)(ru)濾(lv)池(chi)，經過濾(lv)層(ceng)自上(shang)而(er)下(xia)(xia)地(di)過濾(lv)，清水(shui)(shui)(shui)(shui)即從(cong)連(lian)通(tong)管(guan)(guan)(guan)注(zhu)入(ru)(ru)箱(xiang)內貯存，水(shui)(shui)(shui)(shui)箱(xiang)充滿水(shui)(shui)(shui)(shui)后水(shui)(shui)(shui)(shui)流通(tong)過出水(shui)(shui)(shui)(shui)管(guan)(guan)(guan)入(ru)(ru)車間。濾(lv)層(ceng)不斷(duan)截(jie)留(liu)懸浮物，造(zao)成(cheng)濾(lv)層(ceng)阻力(li)逐(zhu)漸增加因而(er)促使虹(hong)(hong)吸(xi)(xi)上(shang)升管(guan)(guan)(guan)內的(de)水(shui)(shui)(shui)(shui)位(wei)不斷(duan)升高，當水(shui)(shui)(shui)(shui)位(wei)達(da)(da)到(dao)(dao)虹(hong)(hong)吸(xi)(xi)輔助管(guan)(guan)(guan)關口時(shi)，水(shui)(shui)(shui)(shui)自該(gai)管(guan)(guan)(guan)中落(luo)下(xia)(xia)，通(tong)過抽(chou)氣管(guan)(guan)(guan)，借以帶走虹(hong)(hong)吸(xi)(xi)下(xia)(xia)降管(guan)(guan)(guan)中的(de)空(kong)氣，當真空(kong)達(da)(da)到(dao)(dao)一定值(zhi)時(shi)便發生虹(hong)(hong)吸(xi)(xi)作用，這時(shi)水(shui)(shui)(shui)(shui)箱(xiang)中的(de)水(shui)(shui)(shui)(shui)自下(xia)(xia)而(er)上(shang)地(di)通(tong)過濾(lv)層(ceng)，對濾(lv)料進行反沖(chong)，當沖(chong)洗(xi)水(shui)(shui)(shui)(shui)箱(xiang)下(xia)(xia)面下(xia)(xia)降到(dao)(dao)虹(hong)(hong)吸(xi)(xi)破壞管(guan)(guan)(guan)口時(shi)，空(kong)氣進入(ru)(ru)虹(hong)(hong)吸(xi)(xi)管(guan)(guan)(guan)，破壞虹(hong)(hong)吸(xi)(xi)作用，濾(lv)池(chi)反沖(chong)洗(xi)結束，濾(lv)池(chi)進入(ru)(ru)下(xia)(xia)一周期的(de)工作。
其特點：
1.有(you)(you)充足的(de)填料空間。2.有(you)(you)曝氣功能(neng)。3.有(you)(you)效的(de)過濾井水中所含(han)的(de)金屬含(han)量如：鐵、錳等金屬元素
