| 摘 要： | 探讨了武汉某工业园电镀厂污泥酸浸、除杂提磷的工艺及条件。当H2SO4（浓度为72％）用量为4mL/g污泥，在液固比为5：1，常温搅拌浸出时间为1h，用碱液调节浸出液pH为4后沉淀1h，过滤，磷的浸出率为86％，铁的沉淀率达到94．2％，除铁后的浸出液进一步用NH4HCO3净化，并制取磷铵产品，总养分（N＋P2O5）为52％。产品达到国家合格品的标准。

| Abstract: | The craft and conditions of refining phosphorus by pickling and removing impurities from electroplating sludge in a industrial park in Wuhan were explored .When the amount of H2SO4 （C=72%）was 4 mL/g, the liquid-solid ratio at 4：1 and stir leaching time for lh at room temperature , the phosphorus lixiviated efficiency was 86% with precipitating for lh after adjusting the leaching solution at pH 4, while ,the iron sedimentation rate was 94.2%. Purify the lixiviated liquid after removing iron with NH4HCO3, then the AP products were made ,the total nutrient （N＋P2O5） was 52%.The products reach the state qualified grade. |
