Tertiary treatment of biologically treated effluents from pulp and paper industry by microwave modified activated carbon adsorption
Popis výsledku v původním jazyce
Nowadays, biologically treated effluents (BTW) from pulp and paper industry still contain a significant organic load, which makes it unsuitable to discharge directly into the waterway. Therefore, a tertiary treatment by activated carbon adsorption was investigated. To improve the treatment efficiency of BTW in the pulp and paper industry, wood-based activated carbon (WAC) was modified by microwave irradiation (MWAC). WAC and MWAC were characterized by scanning electron microscopy, N-2 adsorption, elemental analysis, Fourier transform infrared and X-ray photoelectron spectroscopy. Compared with WAC, MWAC has a higher surface area and lower oxygen-containing groups. The BTW adsorption capacity of MWAC is higher than that of WAC. WAC and MWAC were used to remove chemical oxygen demand (COD) in BTW and the effects of adsorbent dosage, contact time, pH and temperature on the removal of COD in BTW were studied. The adsorption isotherms of WAC and MWAC revealed that the Langmuir models applied to the adsorp
