Preparation and Application of Biochar from Brewery`s Spent Grain and Sewage Sludge
Brewerys spent grain (BSG) and sewage sludge (SS) were used as raw material at the temperature from 400°C to 700 °C and limited oxygen (O2 600°C > 500°C >400°C increased from 6.0 to 10.1. FT-IR results showed: BC rich in carboxyl and phenolic hydroxyl which were surface oxygen functional groups. Electron microscope scanning (EMS) analysis results indicated: when the temperature was 400°C, the surface of BC formed tiny holes, but was fuzzy; with the pyrolysis temperature increasing, plug of the hole opened and walls became thinner. BC adsorption results showed: under same pyrolysis temperature, adsorption effects were best under the proportion of SS 80% for ammonia-nitrogen, 100% for phosphorus-containing wastewater, and 10% for chromium (VI) wastewater. BC prepared under higher temperature had the better removal effect for wastewater.
