Abstract:
After biological deodorization, the odor generated and collected from the sludge treatment workshop of a sludge composting plant in Beijing cannot meet the new local Emission Standard of Air Pollutants for Municipal Wastewater Treatment Plant (DB 11/2007-2022), and urgently needs to be upgraded. In view of the high concentration of ammonia and the certain dust generated by sludge treatment, the combined deodorization process of washing, pickling, biological deodorization, and adsorption is adopted to achieve the discharge standard and improve the environmental quality of the workshop and the surrounding area of the plant.
