Study on Preparation of Water Treatment Ceramic Particles by Using Sludge and Fly Ash and the Ceramic Particles’ Application
Water treatment ceramic particles were prepared using dewatered life sludge in Huainan No.1 Sewage treatment plant and power plant fly ash as main materials and clay as the bond. Through the L9 (43) orthogonal test, we obtained the best conditions of the preparing process. The product can be used as water treatment packing ceramic particles and simulated adsorption experiment with the wastewater including Pb2 + was conducted. The results indicate that ceramic particles (used as wastewater treatment filler) bibulous rate is 25.0%, the loose density is 690kg/m3, the particle density is 1240kg/m3, specific surface area is 5.997m2/g, the compressive strength is 9.40MPa and the adsorptive performance is excellent. The toxic metal leaching experimental result shows that the concentration of toxic heavy metals in leaching solution is in the range of GB specification and the performance of product is stable which will not cause second pollution.
