丝厂废水－粉煤灰资源化产物的肥效试验研究

Study on the Fertility of Wastewater Residue-Fly Ash Mixture Products.

本文对以粉煤灰过滤混凝的丝厂废水后而成的粉煤灰复合肥的肥效进行了盆栽试验研究，证明其具有优质农家肥同等的肥效，该复合肥也不会导致重金属的污染，且该肥的含氮量还可通过增大过滤的灰水比进一步提高。

AbstractThe preparing procedure and the fertility of wastewater residue fly ashmixture were studied. The experimental results showed that the mixture hadthe same fertility as superior farm and Without any heavy metal pollution.
