在自来水反冲的行业螺杆鼓风机起到什么作用？

水厂常规处理净水构筑物的工序，滤池运行的好坏直接影响到水厂的出水水质。但是很多滤池在运行一段时间后，就会出现过滤层含泥量增大。

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.

在反冲洗强度设计值范围内不能达到预期的反冲洗效果，并且冲洗历时延长，产水量下降，严重阻碍了快滤池的正常运行。反冲洗的效果好坏会直接影响过滤行为，如果滤池冲洗的效果不佳，就会产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.

目前滤池反冲洗主要有三种方式：单纯用水反冲洗、用水反冲洗并辅以表面冲洗和气水反冲洗。与其他两种反冲洗工艺相比，气水反冲洗是目前使用多的一种工艺方式。

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.

这跟它成熟的和的工艺历史有关，随着技术的完善得到了推广和采用。而作为气水反冲洗的重要设备之一克虏伯螺杆鼓风机，发挥着中流砥柱的作用。克虏伯螺杆鼓风机直接向滤池供气，且具有效率高、设备简单、操作方便的优势。

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.
