水热碳化是一种新兴的、高效的湿废物利用技术。然而，水热碳化水相（HAP）是一种富含碳的液体产物，含有大量营养元素，其利用在很大程度上尚未开发。本研究以城市污泥和猪粪为原料，在180 °C和260 °C条件下进行水热碳化，制备HAP，并将其作为水稻田部分尿素（9.1-55.9%）的替代物。结果表明，与不加HAP的对照相比，HAP使土壤溶解性有机质（DOM）中类胡敏酸类物质和微生物代谢副产物的丰度分别增加了3.3-7.2倍和42.1- 101.6%.与对照相比，HAP显著提高了土壤荧光和土壤DOM腐殖化指数，分别提高了28.5-41.9%和12.3- 26.8%。施SHAP 260的土壤矿质氮、总有机碳和Olsen-P含量均高于对照。HAP处理水稻籽粒吸氮量比对照提高34.0-58.8%，产量提高6.3-34.1%，籽粒必需氨基酸含量提高8.6-20.9%。本研究表明，HAP作为部分尿素的替代物用于稻田还田对土壤肥力和粮食产量有积极的影响。
Hydrothermal carbonization is an emerging and efficient technology for utilizing wet waste. However, the utilization of hydrothermal carbonization aqueous phase (HAP), a carbon-rich liquid product containing massive quantities of nutrient elements, has been largely unexplored. In this study, HAP produced by hydrothermal carbonization of sewage sludge (SHAP) and pig manure (PHAP) at 180 °C and 260 °C was applied as a substitute for partial (9.1–55.9%) urea in rice paddy field. Results showed that HAP increased the abundance of humic acid-like substances and microbial metabolic by-products in soil dissolved organic matter (DOM) by 3.3–7.2 times and 42.1–101.6%, respectively, compared to the control treatment without HAP addition (CK). Meanwhile, HAP significantly increased soil fluorescence and humification index of soil DOM by 28.5–41.9% and 12.3–26.8%, respectively, in comparison with CK. Soil fertilized with SHAP260 had greater mineral nitrogen, total organic carbon and Olsen-P compared to CK. HAP increased the grain N uptake by 34.0–58.8% and rice yield by 6.3–34.1% with essential amino acids in grains improved by 8.6–20.9% compared to CK. This study stated that HAP as a substitute of partial urea for rice paddy return has positive effects on soil fertility and grain yields.
