Formula and method for producing foamed ceramic from fly ash and sludge of sewage treatment plant
The invention relates to a formula for producing foamed ceramic from fly ash and sludge of a sewage treatment plant. The formula comprises the following raw materials in parts by weight: 15-35 parts of garbage fly ash, 10-35 parts of sludge, 0-20 parts of kaolin, 20-40 parts of quartz tailings, 5-30 parts of feldspar, 0.1-2 parts of a foaming agent and 1-3 parts of an auxiliary agent. The invention also provides a method for producing the foamed ceramic by using fly ash and sludge from a sewage treatment plant. The method has the advantages of high water resource utilization rate and low new water consumption, realizes combustion under the conditions of high wind temperature and low oxygen concentration by adopting diffuse anaerobic high-temperature sintering, and can effectively remove dioxins. Because of low oxygen consumption in the combustion process, by matching with a heat storage type waste heat recovery technology, hot air generated by diffuse-type anaerobic high-temperature firing can be reused for drying and preheating of materials, so that energy is saved.
一种飞灰加污水处理厂污泥生产发泡陶瓷的配方，配方中原料组成按重量计为：按重量计为：垃圾飞灰15‑35份，污泥10‑35份，高岭土0‑20份，石英尾矿：20‑40份，长石5‑30份，发泡剂：0.1‑2份，助剂1‑3份。还提供一种飞灰加污水处理厂污泥生产发泡陶瓷的方法，该方法中水资源利用率高，新水用量少，采用弥散式厌氧高温烧成实现了高风温和低氧气浓度条件下的燃烧，可有效去除二噁英，由于燃烧过程中耗氧量少，搭配蓄热式余热回收技术，可将弥散式厌氧高温烧成产生的热风回用于物料的干燥预热，节省了能源。
