    多介质过滤器滤料的选择依据
    来源:http://www.jnlzsb.com 发布时间:2019-04-22

    多介质过滤器是本系统的重要预处理装置,它采用均质石英砂和无烟媒作为滤料,它的作用是滤除原水带来的细小颗粒、悬浮物、胶体等杂质,保证产水水质满足反渗透装置的进水水质要求。
    Multimedia filter is an important pretreatment device of this system. It uses homogeneous quartz sand and smokeless media as filter material. Its function is to filter out fine particles, suspended solids, colloids and other impurities brought by raw water, so as to ensure that the quality of produced water meets the requirements of influent water quality of reverse osmosis device.
    多介质过滤器(滤床),既采用两种以上的介质作为滤层的介质过滤器,在工业循环水处理系统中,用以去除污水中杂质、吸附油等,使水质符合循环使用的要求。过滤的作用,主要是去除水中的悬浮或胶态杂质,特别是能有效地去除沉淀技术不能去除的微小粒子和细菌等,BODs和COD等也有某种程度的去除效果。
    Multimedia filter (filter bed), which uses more than two kinds of media as filter layer, is used to remove impurities and adsorb oil in industrial circulating water treatment system, so that the water quality meets the requirements of recycling. The main function of filtration is to remove suspended or colloidal impurities in water, especially small particles and bacteria which can not be removed by precipitation technology. BODs and COD also have some removal effect.
    滤料的选择依据
    Selection Basis of Filter Material
    (1)必须有足够的机械强度,以免在反冲洗过程中很快地磨损和破碎;
    (1) Sufficient mechanical strength must be provided to prevent rapid wear and tear during backwashing.
    (2)化学稳定性要好;
    (2) Good chemical stability;
    (3)不含有对人体健康有害及有毒物质,不含有对生产有害、影响生产的物质;
    (3) It does not contain substances harmful to human health or toxic substances, or substances harmful to production or affecting production;

    (4)滤料的选择,应尽量采用吸附能力、截污能力大、产水量高、出水水质好的滤料。
    (4) In the selection of filter materials, the filter materials with high adsorption capacity, high sewage interception capacity, high water yield and good effluent quality should be adopted as far as possible.
    在滤料中,卵石主要是起支撑作用,在过滤工艺过程中,因其强度高,相互之间的间距缝隙稳定,孔隙大,便于正洗工序中,滤后水顺利通过;同样,反洗工序中,反洗水和反洗空气等能顺利通过。常规配置中,卵石分为四种规格,铺垫方式为自下而上先大后小。
    In the filter material, the pebble mainly plays a supporting role. In the process of filtration, because of its high strength, stable gap between each other, large pore, easy to wash in the process, filtered water can pass smoothly; similarly, in the process of backwashing, backwashing water and backwashing air can pass smoothly. In the conventional configuration, the pebbles are divided into four specifications, and the paving method is from bottom to top first big and then small.
