Preparation method for firing light tourmaline ceramsite through sewage sludge and pulverized fuel ash
The invention discloses a preparation method for firing light tourmaline ceramsite through sewage sludge and pulverized fuel ash. The method includes the steps that 1, tourmaline, sewage sludge and pulverized fuel ash are dried; 2, the dried tourmaline, sewage sludge and pulverized fuel ash are crushed; 3, crushed tourmaline particles, sewage sludge particles and pulverized fuel ash particles are mixed, so that a dry mixed material is obtained; 4, an addition agent, water and the dry mixed material are mixed and then are subjected to extrusion forming, and accordingly ceramsite blank is obtained; 5, the ceramsite blank is placed in a muffle furnace to be sintered, and the process is completed. According to the preparation method, the sewage sludge and the pulverized fuel ash are used as raw materials, resource utilization of the sewage sludge and the pulverized fuel ash is realized, the defect of being high in ceramsite preparation cost is overcome, and secondary pollution is further effectively prevented. Due to the fact that the tourmaline is added, the biological affinity of the ceramsite is improved, and the sewage treatment efficiency of the ceramsite is also improved.
