污水污泥产生量大且成份复杂,除少量得到有效处置外,大部分污泥最终出路不明确.污泥处置环节存在潜在环境风险.结合上海某污水处理厂污水污泥性质,对比分析了国内外的污水污泥控制标准及国内外较为成熟实用的土地利用方式的利弊,讨论了污泥土地利用的可行性.认为经过处理后的污水污泥可用于绿化用土、土壤改良,并应加强污泥制片流通环节的管理.

Most of sewage sludge is not reasonable disposed, which has huge output and complex composition. There are potential environmental risks during sludge disposal area. Combining with the nature of the sludge coming from a sewage treatment plant in Shanghai, the advantages and disadvantages of control standards for sewage sludge at home and abroad were comparative analyzed, the feasibility of sludge for land use was discussed. It considered that sewage sludge after treatment can be used for gardening and soil remediation, and the management of sludge production in the circulation link should be strengthened.
