摘要
以绢纺厂废水为对象，用硫酸亚铁作为水处理剂，将处理绢纺厂废水后的沉淀污泥作为铁－氮复合肥，对经缺铁营养液水培后的缺铁大麦进行了补充铁元素的试验．结果表明：缺铁大麦用这种污泥补铁１周后，即可改善症状，两周后。
After the sewage from silk spinning factory was disposed by ferrous sulfate,some sludge were generated.The sludge was used as the Fe N compound fertilizer to supply the Fe element for the iron deficiency barley which was cultured in the non iron cultivation liquid,and the experiment showed that the barley the iron deficiency symptom cultured in was began to improve when the sludge was supplied to the barley that grew in the non iron cultivation liquid for 1 week,and 2 weeks later, the barley returned to be normal.
