摘　　要：本文对粉煤灰的肥效和以过滤法提高粉煤灰肥效的途径进行了研究，并对粉煤灰过滤经混凝后的丝厂废水制成的粉煤灰友合肥的肥效进行了田间试验，证明其具有与优质在家肥同等的肥效，且不会导致重金属的污染。该肥的含氮量可通过稍加处理而进一步提高。篢he production procedure and the fertilizer efficiency of filter residue from silk factory wastewater treatment Plant applying coagulation－filtration process in which fly coal ash was used as filtering medium. Field test showed this residue，a com- pound feitilizer， had the same fertilizer efficiency as good as faim manure and no heavy metal pollution occurred.
