Structure Evaluation and Microbial Biomass Determining of Biological Activated Carbon
To investigate the microorganisms growth process and biostability of biological activated carbon by manual preparation, the microorganisms growth process were observed by the photos of optics and electronic microscope, and the microbial biomass was determined by phospholipids (Lipid-P) analysis. The bell bug, rotifer and eelworm were observed by the photos of optics and electronic microscope. The zoogloea size of the foster biological active carbon was big, the configuration was tight. The quantity of zoogloea on the top of BAC column was more than that on the below. The Lipid-P biomass of BAC on the top and below were 16nmolP/cm3 and 6.2nmolP/cm3 respectively, as same as that was the number of E. Coli cells were 1.6×109cfu/cm3 and 6.2×108cfu/cm3 respectively in 60-days. The Lipid-P biomass decreased to 90 days. The biological activated carbon was obtained by manual culture.
