- 摘要:
- 保定市污泥处理中心项目设计处理规模为300 t/d（污泥含水率为80%），结合当地污水处理厂的泥质、泥量、用地条件、添加剂、辅助原材料和能源供应条件及污泥处置的最终出路，通过对好氧发酵、热干化、厌氧消化等几种工艺进行比较选择，确定厌氧消化+板框脱水为污泥的最终处理工艺。经过生产性实验，测定了保定市污水处理厂污泥产气率及硫化氢和二氧化碳含量，结果显示项目环境效益显著。结合该项目污泥处理工艺，对污水处理厂主流工艺提出了新的低碳节能的改良方案。
- 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〗
