초록

The purpose of this study is to efficiently treat the sewage sludge discharged from sewage treatment plants and evaluate the feasibility of the manufacture of lightweight aggregates(LWA) using a large quantity of sewage sludge and inorganic waste binder ;f1y-ash, waste-stone, tailing, phosphogypsum. Then they were burned in different soak temperatures from 1190$^{circ}C$ to 1290$^{circ}C$ with fixed soak time and heating rate at 5 minutes and 20$^{circ}C$/min respectively in order to produce lightweight aggregate (LWA). Experiment were generated to evaluate the quality of LWA as well as the relationship between burning condition and product's quality.
