摘要
对污泥、垃圾和粉煤灰进行成分及重金属含量检测 ,用污泥、垃圾和粉煤灰混合堆肥制成有机复合肥 ,并对水稻进行施肥试验 ,结果表明 :桂林市城市污水污泥及垃圾中有机质和 N、P、K含量丰富且不超标 ,堆肥制成的有机复合肥增产效果显著 ,具有广泛的应用价值。
The composition and heavy metals content of sludge, solid wastes and coke breeze is detected in the test. Sludge, solid wastes and coke breeze compost the organic composite fertilizer. The experiments on it for rice fertilization were conducted. The results show that the contents of organic matter and N, P, K in wastewater sludge and solid wastes of Guilin are very abundant and heavy metals remain under the criteria. There is a significant efficiency for the organic composite fertilizer applied in raising rice yield, providing an extensive applicability.
