江苏太湖淤泥的农用方式及风险防控措施

Agricultural Application Methods and Risk Control Measures of Taihu Lake Mud in Jiangsu Province

基于太湖淤泥测算量及打捞量,针对江苏太湖底泥生态疏浚工程中面临越来越突出的淤泥处置和利用问题,重点探讨了湖泊淤泥处理的5种利用方式:有机肥料、绿化基土、湿地回填土、生态营养土、环保营养钵;提出了农用前应考虑施用地土壤质地、p H和有机质参数,对淤泥的理化性质加以分析以及严格控制有毒、有害物质及病原微生物等污染物符合国家标准,控制单位面积施用量和施用年限,建立严密的监测体系等污染风险防控措施。

As dredging engineering of Jiangsu Taihu Lake sediment faced more and more prominent problem in the sludge treatment and use, in this paper, based on the Taihu Lake silt calculation quantity and quantity of dredging, probed into five kinds of scientific and reasonable methods of the lake mud treatment, such as organic fertilizer, green based soil, wetlands backfill, nutrition soil and environmental protection pot. And put forward pollution risk prevention and control measures such as considering applying to soil texture, pH and organic matter param- eters before agricultural application; strictly controlling the poisonous and harmful substances and pathogenic microorganisms meet the national standards based on the analysis of the physical and chemical properties of silt; controlling unit area application and use fixed number of a year; establishing rigorous monitoring system et al.
