Technology research and application ofctivated carbon filter

  

is the application of activated carbon technology to eliminate odors from the water began to practice, but with increasing global environmental problems, people gradually research and application of activated carbon to shift the focus to the terms of the removal of organic matter. Application of Activated Carbon forms mainly the following three: (1) replacement portion sand filter with granular activated carbon becomes carbon double sand media filter (also known as domestic bioactive filter). Purification in this manner is better than the sand filter, can reduce the number of backwash, backwash reduced strength, and quickly put into use, more suitable to the presence of odor quality problems, and the organic contamination is less serious. However, due to the shallow depth of the pool sand filter, activated carbon readily simple function of physically adsorbing adsorption saturation, this form of purification effect is limited, and charcoal lighter than sand, and the material easy to run during the operation, but also change the carbon difficult. (2) replace all sand granular activated carbon, i.e., activated carbon adsorption and filtration. In this manner, with the scope and characteristics substantially the same as the first embodiment, for easy carbon, however, activated carbon of a higher quality requirements (especially the particle size distribution of activated carbon), and to strictly control the carbon pool into the water turbidity in 1NTU less, or even lower. (3) set up after the sand filter carbon adsorption chamber, and is often used in combination with ozonation. This prevents clogging of the pore structure of activated carbon are, together with the use of ozone, the activated carbon can be significantly prolonged periods of use, effective use of the biological oxidation of biofilm and adsorption properties of activated carbon. However, investment costs and operating costs significantly increased in this way, more suitable for serious problems odors and organic pollution of water, and when the first two methods can not achieve water quality standards adopted.
