活性炭在水处理中有何作用
活性炭被广泛应用于生活用水及食品工业、化工、电力等工业用水的净化、脱氯、除油和去臭等。一般在除盐水处理过程中,于阳离子交换器的前面(少数的也有设在后面的)设置活性炭过滤器。由于活性炭的比表面积很大,其表面又布满了平均直径办20—30埃的微孔,因此,活性炭具有很高的吸附能力。此外,活性炭的表面有大量的羟基和羧基等官能团,可以对各种性质的有机物质进行化学吸附、以及静电引力作用,因此,活性炭还能去除水中对于阴离子交换剂有害的腐殖酸、富维酸、本质磺醉等有机物质,还可以去除象余氯一类对阳离子交换剂有害的物质,从而提高了除盐水处理能力。通常,能够去除63%~86%胶体物质;50%左右的铁;以及47%~60%的有机物质。
活性炭由于疏松多孔,相对表面积非常大,具有很强的吸附性。在自来水净化工艺中,用活性炭吸附净化一般是用在过滤之后。此时得到的水已经比较澄清,含有少量的不溶性杂质,较多的可溶性杂质(钙镁化合物),异味,颜色。
【1】可吸附水中残留的少量不溶性杂质。
【2】吸附大部分可溶性杂质。
【3】吸附水中的异味。
【4】吸附水中的颜色,使水变得透明,澄清。

活性炭在水处理中有何作用--Activated carbon in water treatment has what function
活性炭被广泛应用于生活用水及食品工业、化工、电力等工业用水的净化、脱氯、除油和去臭等。Activated carbon is widely used in water for life and food industry, chemical industry, electric power and other industrial water purification, dechlorination, degreasing and smelly, etc.一般在除盐水处理过程中,于阳离子交换器的前面(少数的也有设在后面的)设置活性炭过滤器。In general in addition to salt water treatment process, in the front of the cation exchanger (a few also have in the back of the) set carbon filter.由于活性炭的比表面积很大,其表面又布满了平均直径办20—30埃的微孔,因此,活性炭具有很高的吸附能力。Due to the effect of the specific surface area is very big, the surface and was full of average diameter do twenty - 30 angstrom micro hole, therefore, activated carbon has the very high adsorption capacity.此外,In addition,活性炭Activated carbon的表面有大量的羟基和羧基等官能团,可以对各种性质的有机物质进行化学吸附、以及静电引力作用,因此,活性炭还能去除水中对于阴离子交换剂有害的腐殖酸、富维酸、本质磺醉等有机物质,还可以去除象余氯一类对阳离子交换剂有害的物质,从而提高了除盐水处理能力。The surface of a large number of hydroxy and carboxyl functional groups, the various properties of organic matter to carry on the chemical adsorption, and electrostatic attraction effect, therefore, activated carbon can also remove the water for anion exchanger harmful humic acid, rich d acid, essence sulfone drunk and organic matter, still can remove like a residual chlorine to cation exchanger harmful substances, so as to improve the processing ability in addition to salt water.通常,能够去除63%~86%胶体物质;Usually, can remove 63% ~ 86% colloidal substance;50%左右的铁;50% of iron;以及47%~60%的有机物质。And 47% ~ 60% of the organic matter.
活性炭Activated carbon由于疏松多孔,相对表面积非常大,具有很强的吸附性。Due to the loose porous, relative surface area is very large, and has a strong adsorption.在自来水净化工艺中,用活性炭吸附净化一般是用在过滤之后。In tap water purification process, using activated carbon adsorption purification is generally used in filter after.此时得到的水已经比较澄清,含有少量的不溶性杂质,较多的可溶性杂质(钙镁化合物),异味,颜色。Now get water has been compared to clarify, contains a small amount of insoluble impurity, the more soluble impurities (calcium magnesium compound), odor, color.
【1】可吸附水中残留的少量不溶性杂质。【1】 can be adsorbed water a small amount of residual insoluble impurity.
【2】吸附大部分可溶性杂质。【2】 adsorption most soluble impurities.
【3】吸附水中的异味。[3] adsorption odor in the water.
【4】吸附水中的颜色,使水变得透明,澄清。【4】adsorption water color, make water become transparent, clear.
