摘要
统计了大庆市生活污水处理厂污泥泥质重金属含量和本地区土壤环境重金属现状监测值,结果表明:大庆地区土壤属于天然低背景,污泥中重金属含量符合《城镇污水处理厂污泥处置农用泥质》(CJ/T 309-2009)标准的要求。结合本地区土壤的理化性质和污水厂污泥泥质特性,分析堆肥后污泥土地利用前景与环境影响,建议城市污泥处置应遵循源头削减和全过程控制原则,为大庆污泥处理厂的运行和管理提供合理化建议。
This paper studied city on sewage treatment plant sludge argillaceous content of heavy metals and soil environmental status monitoring values of heavy metals in Daqing. The results showed that the soil in Daqing are natural low background, the content of heavy metals in sewage sludge in accordance with the urban sewage treatment plant sludge disposal farm argillaceous （ CJ/T 309 - 2009） standard requirements. Combining with the physical and chemical properties of soil in this region and sewage sludge with argillaceous features, analysis of composting sludge land use prospects and environmental impact, Suggestions of urban sludge disposal should follow the principle of source reduction and whole process control, for Daqing sludge treatment plant operation and management to provide reasonable suggestions.
