| 摘要: |
| 桂林市污水处理厂污泥中有机质、氮、磷和钾等有益组分含量较高,而重金属等有害组分相对较低,基本符合国家污泥农用的有关标准。制成有机复合肥后进行的农用试验表明:污泥有机肥施用后水稻增产13%~19%,肥效略优于或等同于市场上出售的华丰牌复合肥;施用甘蔗后,产量比施用市场上出售的三元复合肥高22%,比施用尿素、钙镁磷肥和氯化钾混合肥高29%。 |

| Abstract: |
| According to the analysis of the sludge of Sewage Treatment Plants in Guilin, the sludge contains a relatively high organic matter, nitrogen, phosphorus and potassium, and relatively low heavy metals. The heavy metals contents accord with the National Standard of Sludge for Agricultural Use. So, the sludge can be used to produce organic complex fertilizer. Based on the results of agricultural experiments, the sludge organic complex fertilizer has a good effect. The output of rice is increased by 13% to 19% over contrast region when the fertilizers are applied. The fertilizer efficiency is a little higher than or equal to the normal complex fertilizer. When the organic fertilizer is applied to sugarcane at the same conditions, the output of sugarcane is 22% higher than that of the used normal complex fertilizer, 29% higher than that of the used the mixed fertilizer of urea,calcium magnesium phosphate, and potasium chloride. |
