Multi media filtration is often used in water treatment. Its detailed function is to remove turbidity from water source, reverse osmosis and ion exchange to soften the pre-treatment of desalination system. It can also be used to remove sediment from surface water and groundwater.

多介質(zhì)過濾器濾料選擇：

Selection of filter media for multi media filter:

(1)必須有足夠的機(jī)械強(qiáng)度，以免在反沖洗過程中很快地磨損和破碎；

(1) It must have enough mechanical strength to avoid quick wear and breakage during backwashing;

(2)化學(xué)穩(wěn)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(zhì)，不含有對生產(chǎn)有害、影響生產(chǎn)的物質(zhì)；

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

(4)濾料的選擇，應(yīng)盡量采用吸附能力、截污能力大、產(chǎn)水量高、出水水質(zhì)好的濾料。

(4) The selection of filter materials should try to use the filter materials with high adsorption capacity, high sewage 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(qiáng)度高，相互之間的間距縫隙穩(wěn)定，孔隙大，便于正洗工序中，濾后水順利通過；同樣，反洗工序中，反洗水和反洗空氣等能順利通過。

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

常規(guī)配置中，卵石分為四種規(guī)格，鋪墊方式為自下而上先大后小。

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

濾料的粒徑和裝填高度之間的關(guān)系

The relationship between the particle size of the filter material and the filling height

濾床的高度和濾料的平均粒徑的比值為800～1 000(設(shè)計規(guī)范)。

The ratio of the height of the filter bed to the average particle size of the filter media is 800-1000 (design specification).

濾料的粒徑的大小和過濾精度相關(guān)。

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