Abstract

The invention relates to the technical field of land reclamation, in particular to a recycling method for reclamation wall soil of waste homestead which comprises the following steps: step 1, dismantling ancillary facilities of waste homestead, digging out a foundation, and turning over soil to obtain reclamation land; step 2, smashing wall buildings of the homestead, and burying the smashed buildings on the surface of the reclamation land to serve as a planting soil layer; step 3, burying a pipeline communicated with a sewer at a position 0.4-0.8 m under the reclamation land, wherein the pipeline is used for absorbing biogas slurry obtained after the soil is filtered; step 4, applying organic fertilizer, a water-retaining agent and biochar to the planting soil layer, and then completing recycling of the reclamation wall soil of waste homestead, wherein the water-retaining agent is bamboo fiber grafted potassium acrylate, and the biochar is peanut shell charcoal. According to the method, resource utilization of building wastes is realized, cyclic conversion of wastes is realized, and the defects of poor agglomeration and low water retention capacity of the reclaimed soil are effectively overcome.

Description

technical field [0001] The invention relates to the technical field of land reclamation, in particular to a method for reusing wall soil reclaimed from abandoned homesteads. Background technique [0002] Homestead reclamation refers to the act of reclaiming legally obtained homesteads with low utilization benefits or abandoned as cultivated land in accordance with the overall plan for land use and the land consolidation and reclamation development plan. The reclamation of rural construction land (homestead) is the product of the implementation and operation of the Chongqing land ticket system, and it is a major innovation in the reform of the rural land system and the realization of the balance between construction land and agricultural land occupation and compensation. According to statistics, the area of ​​rural homestead reclamation in Chongqing has reached nearly 10,000 hectares in the past three years. With the process of urbanization, the scale of homestead reclamation...
