Method for making wetland by backfilling sludge
The invention relates to the technical field of desilting, in particular to a method for making a wetland by backfilling sludge. The method comprises the following steps: step 1, excavating sludge; step 2, filtering sludge; step 3, passivating heavy metals; step 4, sludge solidification; step 5, building a cofferdam; step 6, backfilling sludge; and step 7, plant cultivation. The method has the advantages that plants are planted on the sludge after the sludge is backfilled, the lake ecological environment is improved, the water quality is improved, ecological balance is achieved, the lake is self-adjusted, the sludge does not need to be treated regularly and manpower and material resources are saved.
本发明涉及清淤的技术领域，尤其是涉及一种通过淤泥回填造湿地的方法，包括如下步骤：步骤1：挖淤泥；步骤2：淤泥过滤；步骤3：钝化重金属；步骤4：淤泥固化；步骤5：建造围堰；步骤6：淤泥回填；步骤7：植物种植。本发明具有通过将淤泥回填后在淤泥上种植植物，改善湖泊生态环境，改善水质，从而做到生态的平衡，使湖泊进行自我调节，无需定期处理淤泥，节省人力物力资源的效果。
