摘　　要：将典型水生有机废弃物狐尾藻样品在0~10 MPa压力下压榨,对脱水后样品含水率与压滤液水质进行检测。结果发现:压榨压力在2.5 MPa时,狐尾藻质量可减少53.85%,体积减少超过80%;压滤液中COD、悬浮固体浓度和总磷含量未能达到GB 3838—2002地表水环境质量标准Ⅲ类水排放要求,需要进一步处理。蛋白质含量可达200 mg/L以上,有一定的资源化利用潜力。湖水和压滤液的有机组分包括类蛋白质、类富里酸和腐殖质类物质。其中,湖水中以类蛋白质为主,而压滤液中的类富里酸和腐殖质类物质含量显著提高。Typical aquatic organic waste Myriophyllum verticillatum samples were pressed at a pressure of 0-10 MPa,and the water content of the dewatered samples and the quality of the filtrate were examined.The results found that when the pressing pressure was 2.5 MPa,the mass of Myriophyllum verticillatum could be reduced by 53.85%and the volume reduced by more than 80%.The COD,suspended solids concentration and total phosphorus content in the press filtrate could not meet the Class III water discharge requirements of GB 3838—2002 Environmental Quality Standards for Surface Water,and further treatment was needed.The protein content could reach more than 200 mg/L,which has certain potential for resource utilization.The organic components of lake water and leachate include protein-like,fulvic acid-like and humus-like substances.Among them,the lake water was dominated by protein-like substances,while the content of fulvic acid-like and humus-like substances in the leachate was significantly higher.
