摘要:介绍了10 t/d污泥碳化系统组成及运行工艺，分析了该系统的运行能耗及清洁性，在考察污泥炭相关性质的基础上对污泥炭回归土壤进行了深入讨论。运行数据表明，以含水率为80%、干基低位热值为3 871.5 kJ/kg的市政污泥为原料，系统平均热能消耗为2 728.34 MJ/t，其中污泥自身可提供能耗287.52 MJ/t，外部输入能耗为2 440.82 MJ/t，电能消耗为79.2 kW·h/t。烟气经除尘、洗涤处理，即可实现达标排放，实现污泥清洁性处置。污泥炭中重金属含量符合农用泥质、园林绿化用泥质以及土地改良用泥质标准要求。污泥炭中总养分含量为1.94%，低于园林绿化用泥质及农用泥质标准要求，优于土地改良用泥质要求。该工艺处理的污泥炭均可回归土壤，一方面实现了污泥最终消纳，另一方面实现了养分元素回收利用。
Abstract:A sewage sludge carbonization system and operational process was introduced. The operation energy consumption and the emission of pollutants were analyzed. Based on the investigation of sewage sludge carbon properties, the feasibility of sewage sludge carbon land use was discussed. The moisture content of sewage sludge feedstock was 80%, and its low calorific value was 3 871.5 kJ/kg. The average heat energy consumption of the system was 2 728.34 MJ/t, in which the syngas derived from sewage sludge was 287.52 MJ/t, the external heat quantity required was 2 440.82 MJ/t, and the power consumption was 79.2 kW·h/t. The exhaust gas reached the national standard through the dedusting system and the washing system. The heavy metals contents of sewage sludge carbon reached the control standards for agriculture use, afforestation in gardens or forest, and land improvement. The total nutrients content of the sewage sludge carbon was 1.94%, which was below the control standards for agriculture use, afforestation in gardens or forest, but was beyond the control standards for land improvement. Therefore, the sewage sludge carbon is suitable for land use and nutrients recycling.
