中文摘要 | 本文旨在研究離子樹脂交換法的廢酸回收成效。內容包括產源分析,樹脂床室內 酸回數試驗,和作工廠內完成現場測試結果及可行性評估。 根據現場測試結果,鐵去除率平均 80.41 %。總游離酸回收率平均 74.57 %,其中氫氟酸 平均回收率為 63.68 %,硝酸平均回收率為 89.66 %。而鈣鹼平均節省用量約 65 %,汙 泥減量約 50 %。具有投資費用低廉。設備成本回收時間短的優點,此法可提供中小型廠一 回收廢酸之優良選擇。 |
英文摘要 | The aim of this paper is to study the effect of recovery of nitric acid from solution used by method of iron-resin exchange, first, the resin bed acid recovery test was done at laboratory, then the evaluation of feasibility and the operation at site were practiced at work shop. The experimental data shows that the average of iron removal rate was 80.41%, recovery rate of total acid used was 74.57%, wherein the average recovery rate of HF and NaCO �� were 63.68% and 89.66% respectively. These results indicate that the Ruthner method for recovery acid was a low coat and convenient technique. |
