摘要:

以采取“热水解+高温厌氧消化+板框脱水+带式干化”工艺的某市政污泥集中措置项目为例，搜集该项目一个天然年内的出产进泥泥质、沼气产量和各工段热能耗损等现实出产数据，阐发泥量变化趋向与分歧运转体例下的热能均衡环境。成果注解，污泥无机质与含固率呈季候性转变。当无机质含量为30%~46.16%的污泥采取全工艺链处置时，处置1 t干污泥（DS）需弥补沼气19~92 m^{3，项目方可实现热能均衡。不斟酌带式干化时，污泥无机质含量应高在36.88%方可包管项目能量均衡。高湿度季候之外的清灰功课可有用避免汽锅受热面积灰致使的短时间汽锅热效力降落，并避免因积灰回潮致使的受热面全体侵蚀。}

Abstract:

This paper collected the actual operational data of a municipal sludge centralized disposal project with process consisting of thermal hydrolysis, high temperature anaerobic digestion, plate frame dewatering and belt drying in a natural year, such as the quality of sludge, biogas yield and thermal energy consumption of each section, and analyzed the variation of sludge quality and the thermal energy balance under different operational modes. The organic matter and solid content of the sludge changed seasonally. When the sludge with organic matter content of 30%-46.16% was treated in the whole process chain, biogas with volume of 19-92 m^{3should be added to treat each ton of dry sludge (DS), so that the project could achieve thermal energy balance. When the belt drying was not operated, the organic matter content of the sludge should be higher than 36.88% to achieve the thermal energy����APP balance of the system. The ash-cleaning outside the season of high humidity effectively avoided the short?term reduction of boiler thermal efficiency caused by ash accumulation on boiler heating surface and prevented the overall corrosion of heating surface caused by moisture regain of accumulated ash.}
