Multimedia filter is a kind of equipment that uses one or several filter media to remove suspended impurities and clarify water effectively by passing turbidity water through granular or non-granular materials with a certain thickness under certain pressure. Now the application can be said to be very extensive. Here is a brief introduction to the matters needing attention in processing and acceptance of multi-media filter.

(1)要求出水槽與濾板的平行允差不大于2 mm。

(1) Parallel tolerance between outlet flume and filter plate is not more than 2 mm.

(2)濾板的水平度及不平度均小于±1．5 mm。濾板的結構，采用整體加工優(yōu)。當筒體直徑較大時，或受原材料、運輸?shù)确矫嬷萍s時，也可采用兩瓣拼接成形。

(2) The level and unevenness of the filter plate are less than (+1.5 mm). The structure of filter plate is optimized by integral processing. When the diameter of the cylinder is large, or restricted by raw materials, transportation and other aspects, it can also be formed by two-piece splicing.

(3)對濾板和筒體各接合部位的合理處理，對空氣反洗環(huán)節(jié)尤為重要。

(3) Reasonable treatment of the joint parts of the filter plate and the cylinder is particularly important for air backwashing.

①為消除因濾板加工和筒體卷制等方面誤差造成的濾板和筒體的徑向間隙，一般采用圓弧環(huán)板逐段焊接。接觸部位必需采用滿焊。

In order to eliminate the radial clearance between the filter plate and the cylinder caused by the errors in the processing of the filter plate and the rolling of the cylinder, arc annular plate is usually welded step by step. Full welding must be used for contact parts.

②中心管道和濾板的徑向間隙處理方法同上。

(2) The treatment method of radial clearance between central pipeline and filter plate is the same as above.

備注：上述措施，確保了過濾和反洗只能通過濾帽或排管間隙連通。同時，也就保證了反洗和過濾通道的分布均勻性。

Note: The above measures ensure that filtration and backwashing can only be connected through the gap between the filter cap and the drain pipe. At the same time, the distribution uniformity of backwashing and filtering channels is ensured.

(4)濾板上加工的通孔，徑向誤差為±1．5 mm。濾帽導桿和濾板通孔之間配合尺寸的增大，不利于濾帽的安裝或固定。通孔的加工必須采用機械設備。

(4) The radial error of the through hole machined on the filter plate is (+1.5 mm). The increase of the matching size between the guide rod of the filter cap and the through hole of the filter plate is not conducive to the installation or fixing of the filter cap. Mechanical equipment must be used in the processing of through holes.

(5)濾帽的材質，尼龍佳，ABS次之。因上部添加的濾料，對濾帽的擠壓負荷極大，要求強度要高，以避免變形。濾帽與濾板的接觸面(上、下表面)需加彈性橡膠墊。

(5) The material of the filter cap is nylon, followed by ABS. Because of the filter material added on the upper part, the extrusion load of the filter cap is very large, and the strength is required to be high to avoid deformation. Elastic rubber pads should be added to the contact surface (upper and lower surfaces) between the filter cap and the filter plate.
