在自來水反沖的行業(yè)螺桿鼓風(fēng)機(jī)起到什么作用？

水廠常規(guī)處理凈水構(gòu)筑物的工序，濾池運(yùn)行的好壞直接影響到水廠的出水水質(zhì)。但是很多濾池在運(yùn)行一段時間后，就會出現(xiàn)過濾層含泥量增大。

In the final process of conventional water treatment structures in waterworks, the operation of filter directly affects the effluent quality of waterworks. However, many filters will increase the sludge content of filter layer after a period of operation.

在反沖洗強(qiáng)度設(shè)計(jì)值范圍內(nèi)不能達(dá)到預(yù)期的反沖洗效果，并且沖洗歷時延長，產(chǎn)水量下降，嚴(yán)重阻礙了快濾池的正常運(yùn)行。反沖洗的效果好壞會直接影響過濾行為，如果濾池沖洗的效果不佳，就會產(chǎn)生一系列的有害作用。

The expected backwashing effect can not be achieved within the design value range of backwashing intensity, and the flushing duration is prolonged and the water yield is decreased, which seriously hinders the normal operation of the fast filter. The effect of backwashing will directly affect the filtration behavior. If the effect of backwashing is not good, it will produce a series of harmful effects.

目前濾池反沖洗主要有三種方式：單純用水反沖洗、用水反沖洗并輔以表面沖洗和氣水反沖洗。與其他兩種反沖洗工藝相比，氣水反沖洗是目前使用多的一種工藝方式。

At present, there are three main ways of filter backwashing: simple water backwashing, water backwashing with surface backwashing and air-water backwashing. Compared with the other two kinds of backwashing process, air-water backwashing is the most commonly used process at present.

這跟它成熟的和的工藝歷史有關(guān)，隨著技術(shù)的完善得到了推廣和采用。而作為氣水反沖洗的重要設(shè)備之一克虜伯螺桿鼓風(fēng)機(jī)，發(fā)揮著中流砥柱的作用?？颂敳輻U鼓風(fēng)機(jī)直接向?yàn)V池供氣，且具有效率高、設(shè)備簡單、操作方便的優(yōu)勢。

This is related to its mature technology and history. With the improvement of technology, it has been popularized and adopted. As one of the important equipment of air-water backwashing, Krupp screw blower plays a key role. Krupp screw blower directly supplies air to the filter, and has the advantages of high efficiency, simple equipment and convenient operation.
