Removal of Organic Matter by Two Kinds of Activated Carbon from Fruit Shell


Removal of Organic Matter by Two Kinds of Activated Carbon from Fruit Shell




2. Removal of Organic Matter by Two Kinds of Activated Carbon




2.1.1 Two kinds of shell activated carbon for CODMs. Figure 1 of the removal reflects the CODMs of two kinds of shell activated carbon filters. Removal effect. It can be seen that under the same hydraulic retention time, the shell activated carbon filter I for CODMs. The removal rate was 12.2% - 27.9% (average 20.3%) and CODMs were obtained by activated carbon filter II. The removal rate was 17.9%1.




52.7% (mean 31.1%) and CODMs in Activated Carbon Shell Filter II. The removal efficiency is better than that of activated carbon filter I. Although the CODM of raw water is better than that of activated carbon filter I. Often higher than 3 mg/L, but after the treatment of activated carbon shell filter, two kinds of carbon filter effluent CODM. All of them are below the standard requirement of 3 mg/L.




It can also be seen from the experiment that the shell activated carbon filter IJ is for CODMs. The regularity of removal did not change significantly with time, that is, CODMs were matured during the development of biofilm on activated carbon from fruit shell in the filter. The effect is not obvious. This may be due to CODM. It is a comprehensive index of organic matter. It reflects the complexity of organic matter composition, and the change of raw water quality is great. It also makes the adsorption of activated carbon from fruit shell and the possible biological oxidation and filtration of CODMs in the later stage of the experiment under the condition of short EBCT. The removal effect is incomplete, so the water quality of the filter effluent fluctuates greatly.
