生产污水处理用5-8mm稀土瓷砂

稀土瓷砂滤料的特点：

稀土瓷砂滤料是由多孔陶瓷原料掺加稀土原料精制而成，具有的过滤吸附能力，高强度、低阻力、耐腐蚀、无毒性、再生简单、使用寿命长等特点。

稀土瓷砂滤料与其它滤料相比的优势：

传统的石英砂、花岗岩、无烟煤等滤料孔隙率低，比表面积小，截污能力差，产量低，水质不稳定。过滤周期和使用寿命短，难以满足各种成份复杂的工业废水处理和污染日渐加重的生活用水、工业用水深度处理的要求。 　　针对传统滤料存在的缺陷，并根据国外新型滤料研制的经验，采用优质高岭土、粘结剂、成孔剂、稀土抗蚀剂，经高温烧制成外观白色，质地坚硬，颗粒均匀，微孔发达，孔隙率大，圆度饱满的新型滤料——稀土瓷砂滤料。 　　瓷砂滤料具有稳定的化学性能，耐磨擦、抗冲击、耐腐蚀、耐高温，比表面积大，截污能力强，吸附性能好，颗粒均匀，比重适当，使用寿命长达15年左右。稀土瓷砂滤料由于添加了含有耐腐蚀的金镧系和锕系原素的稀土，除具有普通型瓷的性能外，抗蚀性能进一走加强，SiO2更加稳定。

稀土瓷砂的优点：　　1、瓷砂滤料具有耐腐蚀，抗氧化，化学性能稳定、过滤阻力小、滤液清、效果好，使用寿命长等优点。 　　2、用于二次循环水处理过滤，过滤水头损失小，再生周期长，再生简易方便，不易阻塞，可达到效益。 　　3、用于化学法处理的废水过滤，重金属去除率达90％以上，悬浮物去除率达100％，浊度去除率90%。 主要用途:稀土瓷砂滤料广泛用于单层滤池、多层滤池、机械过滤器中做过滤介质，处理各种工业污水、工业用水、城市自来水、城市污水、纯水、软水，也可作为生物滤料处理有机污水。还可用于过滤式除尘器做滤料处理各种工业粉尘、锅炉烟尘。

The characteristics of the rare earth porcelain sａnd filter material:

Rare earth porcelain sａnd filter material is made of porous ceramic materials doped with rare earth material, has a strong ability to filtration adsorption, high strength, low resistance, corrosion resistance, non-toxic, simple regeneration, long service life, etc.

Rare earth porcelain sａnd filter materials compared with other filter material advantage:

Traditional quartz sand, granite, anthracite filter material, such as low porosity, specific surface area is small, cutting carrying capacity is poor, low yield, water quality is not stable. Filtration cycle and short service life, difficult to meet all kinds of complex industrial wastewater treatment and pollution of the rising of living water, industrial water treatment.

Aiming at the flaws of the traditional filter material, and according to the experience of the foreign developed new type of filter material, USES the high quality kaolin, binder, pore forming agent, rare earth resist, via high temperature fire into white appearance, hard texture, uniform particles, microporous developed, porosity is large, the new filter material of roundness is full of rare earth porcelain sａnd filter material.

Porcelain sａnd filter material has stable chemical properties, friction resistance, impact resistance, corrosion resistance, high temperature resistant, specific surface area is large, sewage capability is strong, good adsorption performance, uniform particles, appropriate proportion, the service life of 15 years or so. Because of adding rare earth porcelain sａnd filter, the corrosion resistance of gold content of lanthanide and actinide elements of rare earths, in addition to having features of ordinary porcelain, the corrosion resistance into a walk, SiO2 is more stable.

The advantages of rare earth porcelain sand:

1, porcelain sａnd filter material has corrosion resistance, oxidation resistance, chemical stability, filtration resistance small, clear filtrate, effect is good, long life and other advantages.

2, used in secondary circulating water treatment filter, filter head loss is small, regeneration cycle is long, renewable simple and convenient, is not easy to block, can achieve the best benefit.

3, used to deal with the chemical method of waste water filtration, heavy metal removal rate above 90%, and suspended solids removal rate was 99%, and the turbidity removal rate was 90%. Main use: rare earth porcelain sａnd filter material widely used in single layer in multi-layer filter, mechanical filter, filter, filter medium, processing all kinds of industrial sewage, industrial water, urban tap water, urban sewage, pure water, soft water, also can be used as a biological filter material treatment of organic wastewater. Can also be used to filter separator do filter material processing all kinds of industrial dust, boiler soot.

Rare earth porcelain sａnd filter to arrange indicators:

Detection project data detection projects inspection data

SiO2 58 ~ 74% hard degree of level 7 weighs 1.65 g/cm

Compressive strength of 3.43 x 103 pa Fe2O3 1% or less wear rate 0.02%

22-24% Al2O3 grinding degree 0.15 resistance broken rate was 0.75%

Acid 99% rate of water absorption rate of 0.2% porosity 0.2%

95.2% alkali degrees than weighs 2.57 g/cm resistance to temperature from 100 ℃ to 1000 ℃

Rare earth porcelain sａnd purpose:

Rare earth porcelain sａnd filter material used in pharmaceutical, chemical, petroleum, electric power, electroplating, papermaking, wine of different nature of different industries such as water, tap water, industrial water treatment used in the products are widely applied in coal-fired power plant secondary circulating water treatment filter, filter head loss is small, regeneration cycle is long, regeneration simple and convenient, not easy jam, can also be used for chemical treatment of waste water filtration, heavy metal removal rate over 90%, 99%, removal rate of suspended solids, oil removal rate was 99%.
