基于城市污泥的边际土地整治方法及土体构型
摘要：
本发明土地整治工程技术领域，尤其涉及基于城市污泥的边际土地整治方法，包括以下步骤：S1，将边际土地的地表进行整理和清理；S2，在边际土地上铺设城市脱水污泥；S3，在城市脱水污泥上铺设改良剂；S4，将铺设完成的城市脱水污泥与改良剂进行混合旋耕；S5，在混合旋耕后的城市脱水污泥与改良剂上铺设客土；本发明针对边际土地土壤瘠薄、土层薄等问题开发了适宜于进行种植的方法，形成一定厚度、具有肥力的人工土壤，土壤改良成本低、效果好并且能够满足植物生长，既能消纳城市污泥的处置模式，又实现了资源、环境的循环利用。
摘要（英）：

The invention relates to the technical field of land renovation engineering and in particular relates to an urban sludge marginal land renovation method. The method comprises the following steps of tidying and cleaning land surface of the marginal land, paving urban dehydrated sludge on the marginal land, paving modifiers on the urban dehydrated sludge, mixing the paved urban dehydrated sludge and the modifiers and then conducting rotary ploughing, and paving alien soil on the mixed and rotary-ploughed urban dehydrated sludge and modifiers. A plantation method to solve problems of barren marginal land soil and thin soil layer is developed and artificial soil with certain thickness and containing fertility is formed; low soil modifying cost and great effect are achieved; plant growth can be met; urban sludge processing modes can be eliminated; and resource and environment circulation utilization can be achieved.
