复配钝化剂对污染土壤中铅具有良好的稳定效果
|
摘要
本研究利用石灰、磷酸钠、高分子钝化剂及其复配钝化剂对重金属Pb~(2+)污染土壤进行稳定化处理,并通过浸出试验、老化实验、土壤连续浸提实验及淋溶试验研究单一钝化剂与复配钝化剂稳定重金属Pb~(2+)污染土壤效率。最终表明,有机钝化剂TEPA-CSSNa投加量为2%时,其稳定土壤重金属Pb~(2+)效率为94.8%,而复配钝化剂稳定土壤重金属Pb~(2+)效率接近98%;复配钝化剂基本上可将土壤中有效态重金属Pb~(2+)转化为铁锰氧化态等稳定态Pb~(2+);且相比较单一钝化剂,老化时间对复配钝化剂稳定土壤Pb~(2+)效率的影响更小。相比单一传统无机钝化剂、高分子有机钝化剂,复配钝化剂稳定污染土壤Pb~(2+)效果更好。
In this study, heavy metal Pb~(2+)in soil was stabilized by lime, sodium phosphate, polymer passivation agents and compound passivati on agent. Through stable efficiency and continuous soil leaching experimental,polymer passivation stabilization on heavy metal contaminated soils Pb~(2+)was researched. The results showed that the organic passivation agent, the dosage of TEPA-CSSNa is 2%, the stability of soil heavy metal Pb~(2+)efficiency is 94.8%; composite passivator(lime/sodium phosphate +TEPA-CSSNa) stable soil Pb~(2+)efficiency is close to 98%.Composite passivator(5% lime/sodium phosphate +1% TEPA-CSSNa) basically can be effective state of heavy metal Pb~(2+)into Fe or Mn oxidation state of stable state Pb~(2+)in soil. Ans compared with the single passivating agent,the aging time has less influence on the Pb~(2+)efficiency of the stabilized soil. Compared with the traditional single inorganic passivation agent and high polymer organic passivation, the compound passivating agent has better effect of stability of soil heavy metal Pb~(2+)efficiency.
