Pyrolysis of different sewage sludge feedstocks for biochar products: Characterization and application

不同污水厂污泥热解生物炭的特性和应用研究

Abstract

Four sewage sludge (SS) feedstocks with distinct properties were converted into biochars by pyrolysis at 300–700 °C, in order to clarify the effects of the composition difference of SS feedstocks. The yields of biochars present a positive correlation with the contents of ash in SS. Notedly, the contents of organic matter (OM) in SS largely determine the quality of biochars. SS feedstocks with high content of OM are more likely to form stable biochars with higher aromaticity/carbonization degree, and the formed biochars possess higher calorific values. The contents of residual OM in biochars derived from SS feedstocks with low content of OM likely fail to meet the needs of soil improvement (10 wt.%). Most of heavy metals (HMs) existing in raw SS are remained in biochars after pyrolysis. The biochar produced from SS feedstocks with high content of HMs usually contains higher contents of HMs. Surprisingly, the leachability of HMs in biochars is all weakened to some extent compared to raw SS. In addition, the biochars show higher thermal stability and pH values, and P/K nutrients are enriched in biochars. The biochars prepared from four SS feedstocks exhibit different adsorption ability of methylene blue, especially at low dosage of biochar.

摘要

为了明确污泥原料本身构成差异对其热解制备生物炭的影响, 本研究对四种具有不同性质的污泥原料在 300∼700 °C 条件下进行了热解.生物炭的产率与污泥中灰分的含量呈现正相关. 更重要的是, 污泥中有机质含量在很大程度上决定了生物炭的品质. 有机质含量高的污泥原料更容易形成稳定的生物炭 (更高的芳香度/碳化度), 且生物炭具有更高的热值. 有机质含量低的污泥原料热解生成的生物炭中有机质残留量很大概率不能满足土壤改良的需要 (10 wt.%). 污泥中的重金属大部分在热解后仍存在于生物炭中污泥中. 重金属含量高的污泥原料制备的生物炭所含重金属含量也高. 有趣的是, 与污泥原料相比, 生物炭中重金属的浸出能力都有所减弱. 此外, 生物炭具有较高的热稳定性和 pH 值, 且富含 K/P 营养元素. 四种污泥原料制备的生物炭对亚甲基蓝的吸附能力不同, 在生物炭用量低的情况下尤为明显.
