摘要

  • 摘要: 释氧材料经济有效的释氧是地下水原位生物修复的关键因素。实验通过在释氧材料中加入膨润土、磷酸二氢钾和硫酸铵等,改进释氧材料的性能。柱实验结果显示,该释氧材料释氧速率缓慢,释氧时间长,可以使溶液中DO长期保持在5 mg/L以上;另外,释氧材料中添加的缓冲剂及天然含水层介质对pH值有较好的缓冲作用,可以使pH值达到后续生物修复的要求。
    Abstract: It is an important factor if the oxygen-releasing material could release oxygen continuously and economically upon contact with water in situ polluted groundwater bioremediation. The experiment was intended for improving property of oxygen-releasing material through adding bentonite,KH2PO4 and (NH4)2SO4 into calcium peroxide (CaO2).The results of the continuous column experiment show that the oxygen-releasing material could decrease O2-releasing rate and lengthen O2-releasing duration. The DO can retain more than 5 mg/L for long time. In addition, KH2PO4, (NH4)2SO4 and the natural aquifer can better buffer pH and meet the need of bioremediation.
