| 中文摘要: |
| 利用水热炭化技术对大豆分离蛋白生产过程中的副产品污泥（黑泥、蛋白泥）及湿豆渣进行了脱水干燥实验。结果表明：大豆分离蛋白生产过程中的黑泥及蛋白泥的干燥脱水效果良好，含水率85%左右的黑泥及蛋白泥经水热炭化后泥水分离，经挤压脱水后含水率降为30%左右，泥中的有机物质保存比例高。该工艺达到了“无害化、资源化、减量化、稳定化”的要求，运行成本低，对外界环境情况、污泥的有机物质含量、含沙量等要求不高，为企业提供了一种全新的污泥处理工艺。 |
| 英文摘要: |
| The sludge(black sludge and protein sludge) and wet soybean dregs produced in soybean protein isolate production were dried by hydrothermal carbonization technology. The results showed that black sludge and protein sludge were dried well. Sludge and water was separated after hydrothermal carbonization treatment, moisture reduced from 85% to 30% after pressing, and the organic matter content was high. Hydrothermal carbonization technology met the requirement of harmless, recycling, reduction and stabilization, and had the advantages of low cost,and low requirement of environment, organic matter content and sand content in sludge, so it was a new sludge treatment process for enterprise. |
