Web2 days ago · This chemical wastewater treatment process works in a similar fashion as chemical oxidation. Sludge is treated with a large amount of a given oxidant, such as chlorine. The introduction of the oxidant slows down the rate of biological growth within the sludge and also helps deodorize the mixture. The water is then removed from the sludge. WebDifferent redox conditions favor different microbial communities and are used to affect different types of treatment (Judd, 2011 ). Aerobic treatment is used to remove organic compounds (BOD or COD) and to oxidize ammonia to nitrate. Aerobic tanks may be combined with anoxic or anaerobic tanks to provide biological nutrient removal. 18種鹿角蕨
