- Abstract:
- The treatment capacity of Baoding sludge treatment center was 300 t/d (80% moisture content). Combined with some factors in the local wastewater treatment plants such as sludge quality, total amount of sludge, geological conditions, medicament, auxiliary raw materials, energy supply condition, final sludge disposal way, after comparison and selection of aerobic fermentation, heat drying and anaerobic digestion, the combination process of anaerobic digestion and sludge dewatering was decided as the optimal solution. Through the productive experiment, the biogas production rate and the content of hydrogen sulfide and carbon dioxide was determined. The calculation of carbon dioxide emission reduction showed that the project could bring significant environmental benefits. Combined with the sludge treatment process, a new improved scheme of low carbon and energy saving was put forward for the mainstream process of wastewater treatment.〖CS〗
