专业生产水处理用 无烟煤滤料

无烟煤滤料介绍：

     精制无烟煤滤料采用山西优质无烟煤为原料，经精选、破碎、和两次筛分而成，机械强度高，抗压性能好，化学性能稳定，不含有毒物质，耐磨损，在酸性、中性、碱性水中均不溶解，另外无烟煤颗粒表面粗糙，有良好的吸附能力，孔隙率大(＞50%)，有较高的含污能力，因质轻，所需反冲洗强度较低，可节省大量反冲洗水量及电能。

无烟煤滤料同石英砂滤料配合使用是我国目前推广的双层快速滤池和三层滤池、滤罐过滤的最佳材料。是提高滤速增加单位面积出水量和成倍提高截污能力，降低工程造价和减少占地面积最有效的途径。广泛用于化工、冶金、热电、制药、造纸、印染、食品等生产前后的水质处理过程中。

无烟煤滤料用途：

     实用于一般的酸、中、碱性水的净化处理，是双层、三层滤池中不可缺少的净水材料，各项技术指标均达到和超过建设部（CJ/T44-1999）标准。过滤原理：水中之微细悬浮固粒经加药絮凝后，由无烟煤滤材加以滤除。

用于生括给水及工业给水的过滤净化处理。使用时根据滤池的形式确定使用参数，一般双层滤科的铺装厚度为300—400mm；正常滤速10—14m／h，强制滤速14—1 8m／h；三层滤料铺装厚度450mm，正常滤速18—20m／h，强制滤速20～25m／h。滤池反洗采用水冲洗、水汽冲洗或辅以表面冲洗。

无烟煤滤料特点：

    1 .效率高，去除率达99%

    2．处理水量大

    3．使用寿命长

无烟煤滤料理化指标：

无烟煤滤料常用规格：

     0.6-1.2mm 0.8-1.8mm 1-2mm 3-6mm 4-8mm

无烟煤滤料选择标准：　　

无烟煤滤料在过滤过程中所起作用的好坏，直接影响着滤过的水质，故对此滤料的选择必须达到以下几点要求：

    ①机械强度高，破碎率和磨损率之和不应大于3%（百分比按质量计）。

    ②化学性质稳定，不含有毒物质。在一般酸性、碱性、中性水中均不溶解。出厂产品经中国水处理滤料监督检测中心测定：盐酸可溶率为0.68%（部颁标准为3.5）在各类水源中均可达到良好的净化效果。

    ③粒径级配合理，比表面积大。产品外观呈球状而有棱角，光泽度好，经机械振动三次筛分，级配符合有关技术指标。均匀系数（K60）不大于1.5（日本标准），不均匀系数（K80）在1.6-2.0之间，空隙率大于50%。

    ④粒径范围小于指定下限粒径按重量计不大于5%，大于指定上限粒径按重量计不大于5%。

Anthracite filter material is introduced:

Refined by shanxi anthracite filter material quality anthracite as raw materials, the selection, crushing, and two screening and become, high mechanical strength, compressive performance is good, stable chemical performance, do not contain toxic substances, wear resistance, acid, neutral and alkaline water shall not be dissolved, and anthracite coal particle surface roughness, and a good adsorption capacity, pore ratio (> 50%), a higher including carrying capacity, because of the light, the back flush strength is low, can save a lot of backwash water and electricity.

Anthracite filter material with quartz sand filter material used in conjunction with China is the promotion of double rapid filter and three layer filter, filter can filter the best materials. Is to improve the filter speed increase unit area water yield and doubled section carrying capacity, reduce the project cost and reduce covers an area of the most effective way. Widely used in chemical industry, metallurgy, thermoelectric, pharmaceutical, paper making, printing and dyeing, food and other production before and after the water treatment process.

Anthracite filter material USES:

Practical from general acid, and alkaline water purification treatment, it is double, three filter indispensable water purification materials, the technical indicators are reaching and more than the ministry of construction (CJ/T44-1999 standard. Filter principle: the water's fine suspended solid grain after dosing flocculation, the anthracite filter material to filter.

Used for raw water and industrial water supply Europe filtration purification treatment. When using the form of filter according to determine if the use of parameters, general double filter section of pavement thickness for 300-400 mm; Normal filter speed 10-14 m/h, forced filter speed 14-1 8 m/h, Three layer filter material pavement thickness 450 mm, normal filter speed eighteen to twenty m/h, forced filter speed and ~ 25 m/h. Filter backwashing with water wash, rinse with water vapor or surface flushing.

Anthracite filter material features:

1. High efficiency and removal rate 99% 2. Processing capacity big 3. Long service life

Anthracite filter food chemical indicators:

Anthracite filter material commonly used specifications:

0.6-1.2 mm 0.8 1.8 mm 1-2 mm 3-6 mm 4 to 8 mm

Anthracite filter material selection criteria:

Anthracite filter material in the filtering process action is good or bad, a direct impact on the filtered water quality, so the choice of this filter material must meet the following requirements:

(1) high mechanical strength, the broken rate and the wear rate of the should be greater than 3% (percentage in accordance with the quality plan).

(2) the chemical nature is stable, do not contain toxic substances. In the general acid, alkaline and neutral water are insoluble. The factory products by China's water treatment filter material supervision and inspection center determination: hydrochloric acid soluble rate was 0.68% (ministerial standard for 3.5) in all kinds of water source may achieve good cleaning effect.

(3) particle size distribution is reasonable, large specific surface area. Product appearance spherical and angular, good gloss, the mechanical vibration three screening, grading comply with the relevant technical indicators. Uniformity coefficient (K60) is not more than 1.5 (Japan standard), uneven coefficient (K80) in 1.6 2.0, void ratio is more than 50%.

(4) particle size range is less than the specified limit size weight meter is not more than 5%, more than the maximum limit specified size weight meter is not more than 5%.
