摘要:以采用“熱水解+高溫厭氧消化+板框脫水+帶式干化”工藝的某市政污泥集中處置工程為例，收集該工程一個(gè)自然年內(nèi)的生產(chǎn)進(jìn)泥泥質(zhì)、沼氣產(chǎn)量及各工段熱能消耗等實(shí)際生產(chǎn)數(shù)據(jù)，分析泥質(zhì)變化趨勢與不同運(yùn)行方式下的熱能平衡情況。結(jié)果表明，污泥有機(jī)質(zhì)與含固率呈季節(jié)性變化。當(dāng)有機(jī)質(zhì)含量為30%~46.16%的污泥采用全工藝鏈處理時(shí)，處理1 t干污泥（DS）需補(bǔ)充沼氣19~92 m3，工程方可實(shí)現(xiàn)熱能平衡。不考慮帶式干化時(shí)，污泥有機(jī)質(zhì)含量應(yīng)高于36.88%方可保證工程能量平衡。高濕度季節(jié)以外的清灰作業(yè)可有效避免鍋爐受熱面積灰導(dǎo)致的短期鍋爐熱效率下降，并防止因積灰回潮導(dǎo)致的受熱面整體腐蝕。
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 m3 should 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 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.
