Columnar activated carbon can effectively deal with mercury-containing waste water, there is the performance of activated carbon adsorption column of mercury and mercury compounds, but with limited absorption capacity, suitable only for low mercury content in waste water treatment, if higher concentrations of mercury that can be chemically precipitation treatment, after treatment of mercury about 1mg / L, high up 2-3mg / L, and then use the columnar activated carbon for further processing. Columnar activated carbon in wastewater treatment process, if the suspension is too high, it will clog the pores of activated carbon to adsorption capacity decreased, so high levels of these substances should be pretreated, such as precipitation, filtration and the like. Columnar activated carbon filter wastewater before wastewater fixed ionic conditions in some organic polymer and cylindrical carbon strong binding force. Wastewater high metal ion is easily activated carbon adsorption column, when regeneration is difficult to wash it down, the result will reduce the adsorption capacity of the activated carbon column. Thus, in wastewater treatment, should complete the work in each process, the entire process smooth activated carbon treatment, can avoid unnecessary losses. Powdered activated carbon is used as a layer in contact filtration or filtration of treated water in terms of deodorizing charcoal, with less carbon, so water purification activated carbon, very good. However, the particles of their products almost exclusively particles less than 250 mesh, regeneration difficulties decolorizing charcoal, and wood activated carbon manufacturing needs with the same degree of recycling rate, so when you do not currently use regeneration. In contrast, the amount of water required for granular processing unit (broken) to be more than powdered activated carbon Activated carbon, but the former was able to repeatedly use of renewable, which is its advantage. Activated carbon adsorption gas, general and stress-related, and the relationship between this concentration in the liquid phase adsorption same. Thus, water can be used alone desorption regeneration is ideal if you want to use acid, alkali, due to aging may contribute to a chemical adsorption sites, depending on the degree of aging, sometimes in need of regeneration at temperatures above 800 ℃. When using a gas activation method, the activation temperature is in the general manufacturing activated carbon activation temperature range (800-900 ℃). However, even when the regeneration in the manufacture of the activation temperature range, not necessarily the same as obtained with the new activated carbon adsorption capacity.
