Treatment process taking household garbage incineration bottom ash as building material
The invention discloses a treatment process taking household garbage incineration bottom ash as a building material, which comprises the following steps: washing pretreatment, pH value adjustment, drying and dehydration treatment, screening, crushing treatment, sorting treatment, brick making proportioning and brick making, and through the steps, the bottom ash is subjected to washing pretreatment, the bottom ash is soaked, and the bottom ash is subjected to heat preservation; the water-soluble part in the bottom ash is dissolved and filtered, substances such as potassium carbonate and the like are dissolved and eliminated by water, so that the water-soluble substances in the bottom ash are removed from the bottom ash, and the prepared brick body is more resistant to soaking in rainy days and is not easy to break after being laid on the ground; the pH value of the bottom ash in the water tank is adjusted through the sodium hydroxide solution, so that the bottom ash is alkalescent, the prepared brick body is more acid-corrosion-resistant, and the brick body prepared by taking the bottom ash as the building raw material is more acid-corrosion-resistant, more rainwater soaking-resistant and higher in strength.
本发明公开了一种以生活垃圾焚烧底灰为建筑材料的处理工艺，包括以下步骤：水洗预处理、酸碱度调节、晒干脱水处理、筛选、破碎处理、分选处理、制砖配比、制砖，通过这些步骤，将底灰通过水洗预处理，将底灰进行浸泡，将底灰中易溶于水的部分进行溶解过滤，如碳酸钾等物质，通过溶解与水进行消除，使得底灰中易溶于水的物质从底灰中去除，使得制成的砖体铺设在地面上后，在雨水天气中更耐浸泡、砖体不易破碎，在水洗预处理中，通过氢氧化钠溶液对处于水池中的底灰酸碱度进行调节，使得底灰呈现弱碱性，制成的砖体更耐酸性腐蚀，因此使得以底灰为建筑原料制成的砖体更耐酸性腐蚀、更耐雨水浸泡、强度更高。
