Multi media filter is a process that uses one or several kinds of filter media to pass the water with high turbidity through a certain thickness of granular or non granular materials under a certain pressure, so as to effectively remove suspended impurities and make water clear. The commonly used filter materials include quartz sand, anthracite, manganese sand, etc., which are mainly used for water treatment, turbidity removal, softened water, pre-treatment of pure water, etc., and the turbidity of effluent can reach 3 degrees following.

過濾器構成

Filter composition

多介質過濾器主要由過濾器體、配套管線和閥門構成。

The multi-media filter is mainly composed of filter body, matching pipeline and valve.

其中過濾器體主要包括以下組件：簡體；布水組件；支撐組件；反洗氣管；濾料；排氣閥(外置)等。

The filter body mainly includes the following components: cylinder; water distribution component; support component; backwashing gas pipe; filter material; exhaust valve (external), etc.

濾料的選擇依據

Selection basis of filter material

(1)須有足夠的機械強度，以免在反衝洗過程中很快地磨損和破碎；

(1) It must have enough mechanical strength to avoid rapid wear and breakage in the process of backwashing;

(2)化學穩定性要好；

(2) The chemical stability is good;

(3)不含有對人體健康有害及有毒物質，不含有對k8凯发官网入口有害、影響k8凯发官网入口的物質；

(3) It does not contain harmful and toxic substances to human health, and does not contain substances harmful to or affecting production;

(4)濾料的選擇，應盡量采用吸附能力、截汙能力大、產水量高、出水水質好的濾料。

(4) The selection of filter media should try to use the filter materials with high adsorption capacity, pollution interception capacity, high water yield and good effluent quality.

在濾料中，卵石主要是起支撐作用，在過濾工藝過程中，因其強度高，相互之間的間距縫隙穩定，孔隙大，便於正洗工序中，濾後水順利通過；同樣，反洗工序中，反洗水和反洗空氣等能順利通過。

In the filter material, pebbles mainly play a supporting role. In the process of filtration, due to its high strength, stable spacing, and large pores, it is convenient for the filtered water to pass smoothly in the forward washing process; similarly, in the backwashing process, the backwashing water and air can pass smoothly.

常規配置中，卵石分為四種規格，鋪墊方式為自下而上先大後小。

In the conventional configuration, the pebbles are divided into four specifications, and the paving mode is from bottom to top, first large and then small.

濾料的粒徑和裝填高度之間的關係

Relationship between particle size and filling height of filter material

濾床的高度和濾料的平均粒徑的比值為800～1 000(設計規範)。

The ratio between the height of the filter bed and the average particle size of the filter material is 800-1000 (design specification).

濾料的粒徑的大小和過濾精度相關。

The particle size of the filter material is related to the filtration accuracy.
