Shandong Multimedia Filter Manufacturer reminds you that in order to ensure the operation of the follow-up system, multiple filters can be washed in turn, the specific steps are: back washing, air scrubbing, positive washing.

（1）反洗。停運過濾器，切斷進水、出水閥門，打開空氣排放閥門和反洗排放閥門，開啟反洗水泵，緩慢開啟反洗進水閥門，調(diào)整反洗流量到正常反洗流量200 m3/h左右。并觀察反洗出水口是否有無煙煤跑出，以沒有無煙煤跑出為標(biāo)準(zhǔn)反洗15分鐘。

(1) Backwashing. Shut off the filter, cut off the inlet and outlet valves, open the air discharge valves and backwash discharge valves, open the backwash pump, slowly open the backwash inlet valves, and adjust the backwash flow to about 200 m3/h of the normal backwash flow. And to observe whether there is anthracite running out of the backwash outlet, take no anthracite running out as the standard backwash for 15 minutes.

（2）空氣擦洗。反洗之后進行空氣擦洗，目的是把附著在濾料上的污物剝落，強化反洗效果。具體操作方法是：反洗結(jié)束后，關(guān)閉反洗進水閥門，打開底排放水視鏡中上部，即濾料無煙煤上10公分處，關(guān)閉底排，打開羅茨風(fēng)機和進氣閥門，控制進氣強度，具體標(biāo)準(zhǔn)為看上視鏡無煙煤層呈上下動作的懸浮狀態(tài)，不能讓濾料劇烈的上下翻騰，以免發(fā)生亂層現(xiàn)象。

(2) Air scrubbing. The purpose of air scrubbing after backwashing is to peel off the dirt adhering to the filter material and enhance the backwashing effect. Specific operation methods are as follows: after the end of backwashing, close the backwashing inlet valve, open the bottom drainage water to the upper part of the mirror, that is, 10 cm above the filter material anthracite, close the bottom drain, open the Roots blower and the intake valve, and control the intake intensity. Specific standard is that the upper and lower mirror anthracite seam is suspended in an upward and downward motion, so that the filter material can not flip violently, so as to avoid chaotic formation. Elephants.

擦洗5分鐘后，按照之前反洗的方法反洗5分鐘，將擦洗污物排出，直反洗水清澈；關(guān)閉反洗進水閥和反洗排水閥；

After 5 minutes of scrubbing, wash back for 5 minutes according to the previous method of backwashing, discharging the scrubbing dirt until the backwashing water is clear; close the backwashing inlet valve and backwashing drainage valve;

（3）正洗。正洗是投運前的準(zhǔn)備工作，主要是使濾料恢復(fù)接觸過濾和深層過濾的效果，確保多介質(zhì)出水水質(zhì)合格即SDI（污染指數(shù)）≤4。具體操作方法為：打開空氣排放閥門、進水閥門和正洗排水閥門，開啟清水泵，調(diào)整進水流量（按正常運行流量正洗），正洗10分鐘，測試過濾器出水濁度，小于0.5可進行SDI測試，否則繼續(xù)正洗；

(3) Washing. Forward washing is the preparatory work before commissioning. It mainly restores the effect of contact filtration and deep filtration to ensure the quality of multi-media effluent, i.e. SDI (pollution index) = 4. Specific operation methods are as follows: open air discharge valve, intake valve and positive washing drainage valve, open clean water pump, adjust intake water flow (according to normal operation flow, positive washing), positive washing for 10 minutes, test the turbidity of filter effluent, less than 0.5 can be SDI test, otherwise continue positive washing;
