摘要：Compared with composting, hydrothermal treatment (HTT) technology can dramatically shorten the duration for manure waste treatment. This study firstly investigated the effect of HTT on solubilization of N, P and organics from swine manure, and then evaluated the phytotoxicity of liquid product from hydrothermally treated manure by seed germination test. Results show that 98% of N in manure could be converted into soluble form after HTT at 200 degrees C for 60 min. Soluble P in hydrothermally treated manure (at 150 degrees C for 60 min) was 2.7 times that in raw manure. The germination indices (GI) were all greater than 100% when the liquid product (from HTT at 150 degrees C for 60 min) or its diluted samples being used. Results from this study suggest that HIT could be a promising technology for producing safe and value-added liquid fertilizers from swine manure. (C) 2018 Elsevier Ltd. All rights reserved.
