原理簡介：
來水(shui)(shui)(shui)(shui)(shui)由進水(shui)(shui)(shui)(shui)(shui)管(guan)送(song)入(ru)濾(lv)(lv)池，經過(guo)濾(lv)(lv)層(ceng)自上而(er)下(xia)地(di)過(guo)濾(lv)(lv)，清水(shui)(shui)(shui)(shui)(shui)即從連通(tong)管(guan)注入(ru)箱內貯存，水(shui)(shui)(shui)(shui)(shui)箱充滿水(shui)(shui)(shui)(shui)(shui)后水(shui)(shui)(shui)(shui)(shui)流(liu)通(tong)過(guo)出水(shui)(shui)(shui)(shui)(shui)管(guan)入(ru)車間。濾(lv)(lv)層(ceng)不(bu)斷截(jie)留懸浮(fu)物，造成濾(lv)(lv)層(ceng)阻(zu)力逐漸增(zeng)加因(yin)而(er)促使虹(hong)吸(xi)上升管(guan)內的水(shui)(shui)(shui)(shui)(shui)位(wei)不(bu)斷升高，當水(shui)(shui)(shui)(shui)(shui)位(wei)達(da)到虹(hong)吸(xi)輔助(zhu)管(guan)關(guan)口時，水(shui)(shui)(shui)(shui)(shui)自該管(guan)中落下(xia)，通(tong)過(guo)抽氣管(guan)，借(jie)以帶走(zou)虹(hong)吸(xi)下(xia)降管(guan)中的空(kong)(kong)氣，當真空(kong)(kong)達(da)到一定(ding)值時便發生虹(hong)吸(xi)作(zuo)用，這(zhe)時水(shui)(shui)(shui)(shui)(shui)箱中的水(shui)(shui)(shui)(shui)(shui)自下(xia)而(er)上地(di)通(tong)過(guo)濾(lv)(lv)層(ceng)，對濾(lv)(lv)料進行反沖，當沖洗水(shui)(shui)(shui)(shui)(shui)箱下(xia)面下(xia)降到虹(hong)吸(xi)破(po)壞管(guan)口時，空(kong)(kong)氣進入(ru)虹(hong)吸(xi)管(guan)，破(po)壞虹(hong)吸(xi)作(zuo)用，濾(lv)(lv)池反沖洗結(jie)束，濾(lv)(lv)池進入(ru)下(xia)一周期的工作(zuo)。
其特點：
1.有充足的填(tian)料(liao)空間(jian)。2.有曝(pu)氣功能。3.有效的過濾井(jing)水(shui)中所含的金屬(shu)含量如：鐵、錳(meng)等金屬(shu)元素(su)
