多介質(zhì)過濾器(又稱機(jī)械過濾器)是以成層狀的無煙煤、砂、細(xì)碎的石榴石或其他材料為床層，床的由輕和粗品級的材料組成，而重和細(xì)品級的材料放在床的低部。

The multi-media filter (also known as mechanical filter) takes layered anthracite, sand, fine garnet or other materials as the bed layer. The top layer of the bed is composed of light and coarse grade materials, while the heavy and fine grade materials are placed in the lower part of the bed.

（1）其原理為按深度過濾--水中較大的顆粒在被去除，較小的顆粒在過濾器介質(zhì)的較深處被去除。從而使水質(zhì)達(dá)到粗過濾后的標(biāo)準(zhǔn)。

(1) The principle is deep filtration - the larger particles in the water are removed at the top layer, and the smaller particles are removed at the deeper part of the filter medium. So that the water quality can reach the standard after coarse filtration.

(2)性能特點(diǎn)

(2) Performance characteristics

多介質(zhì)過濾器可去除水中大顆粒懸浮物，從而降低水的SDI值，滿足深層凈化的水質(zhì)要求。該設(shè)備具有造價(jià)低廉，運(yùn)行費(fèi)用低，操作簡單;濾料經(jīng)過反洗，可多次使用，濾料使用壽命長等特點(diǎn)。

The multi-media filter can remove the suspended solids of large particles in water, thus reducing the SDI value of water and meeting the water quality requirements of deep purification. The equipment has the advantages of low cost, low operation cost and simple operation; After backwashing, the filter material can be used for many times and has long service life.

(3)應(yīng)用范圍

(3) Scope of application

多介質(zhì)過濾器廣泛用于水處理工藝中，主要用于水處理除濁、軟化水、電滲析、反滲透的前級預(yù)處理，也可用于地表水、地下水的除泥沙等。

Multi media filter is widely used in water treatment process, mainly used for turbidity removal, softening water, electrodialysis, reverse osmosis pre-treatment, also can be used for surface water, groundwater sediment removal, etc.

(4)產(chǎn)品簡介

(4) Product introduction

本產(chǎn)品生產(chǎn)的多介質(zhì)過濾器按控制類型可分為手動型和全自動型。手動型主要是通過閥門的調(diào)節(jié)來控制過濾器的運(yùn)行、正洗、反洗;而全自動型是通過FLECK控制器來進(jìn)行對過濾器運(yùn)行，正洗、反洗等狀態(tài)的控制，按罐體材質(zhì)可分為玻璃鋼罐、碳鋼罐、不銹鋼罐，罐內(nèi)壁可根據(jù)用戶要求做內(nèi)涂環(huán)氧涂層或襯膠防腐。

The multi-media filter produced by this product can be divided into manual type and automatic type according to the control type. The manual type mainly controls the operation, washing and backwashing of the filter through the adjustment of the valve; The full-automatic type is to control the filter operation, forward washing, backwashing and other states through the fleck controller. According to the tank material, it can be divided into FRP tank, carbon steel tank and stainless steel tank. The inner wall of the tank can be coated with epoxy coating or rubber lining for anti-corrosion according to the user's requirements.
