Stabilization treatment method for waste incineration fly ash
The invention provides a stabilizing treatment method for waste incineration fly ash, and relates to the technical field of waste treatment. A stabilizing treatment method for waste incineration fly ash comprises the following steps that after fly ash is subjected to ball milling, the fly ash is put into water to be soaked and then washed with water; washing the washed fly ash with a hydrochloric acid solution, mixing water, the fly ash and a treating agent, stirring, and drying to obtain a treated product; weighing the treated product, cement, slag, fine aggregate, coarse aggregate, a water reducing agent and water, mixing the treated product, cement, slag, fine aggregate and coarse aggregate, adding the water reducing agent and water, uniformly stirring, pouring into a mold, and curing to obtain a finished product. The method can effectively block cancerogenic substances such as dioxin and reduce the leaching rate of heavy metal ions.
本申请提出了一种垃圾焚烧飞灰的稳定化处理方法，涉及垃圾处理技术领域。一种垃圾焚烧飞灰的稳定化处理方法，包括如下步骤：将飞灰球磨后，再放入水中浸泡后水洗；将水洗后飞灰用盐酸溶液洗涤后，将水、飞灰和处理剂混合，搅拌后，干燥处理，得到处理产物；称取处理产物、水泥、炉渣、细骨料、粗骨料、减水剂和水，将处理产物、水泥、炉渣、细骨料、粗骨料混合，再加入减水剂和水，搅拌均匀，倒入模具中，养护后，得到成品。此方法可以有效封锁二噁英等致癌物质和降低重金属离子浸出率。
