The traditional pretreatment needs to periodically carry out back washing and forward washing on a multi-medium filter and an activated carbon filter to wash impurities filtered in the filter out of the filter so as to keep the filter and filter materials clean. The softening filter needs to be periodically regenerated by absorbing salt, and the activity of the resin is kept. The softening filter adopts a one-use-one-standby mode to achieve non-stop regeneration, and production operation is not influenced. The back washing and the forward washing are carried out by multi-media and activated carbon in 50 minutes generally, if the water-steam mixed washing is carried out, the time is longer, and the equipment cannot carry out water production operation in the forward washing and back washing processes, so that the water consumption of the subsequent process is seriously influenced.
