This work investigates the influence of electrokinetic-bioremediation (EK-BIO) on remediating soil polluted by persistent organic pollutants (POPs) and heavy metals (mainly Cu, Pb and Ni), originated from electronic waste recycling activity. The results demonstrate that most of POPs and metals were removed from the soil. More than 60% of metals and 90% of POPs in the soil were removed after a 30-day EK-BIO remediation assisted by citrate. A citrate sodium concentration of 0.02 g/L was deemed to be suitable because higher citrate did not significantly improve treatment performance whereas increasing dosage consumption. Citrate increased soil electrical current and electroosmotic flow. After remediation, metal residues mainly existed in stable and low-toxic states, which could effectively lower the potential hazard of toxic metals to the surrounding environment and organisms. EK-BIO treatment influenced soil microbial counts, dehydrogenase activity and community structure.

这项工作调查了电动生物修复（EK-BIO）对修复由电子废物回收活动产生的持久性有机污染物（POP）和重金属（主要为Cu，Pb和Ni）污染的土壤的影响。结果表明，大多数持久性有机污染物和金属已从土壤中清除。在柠檬酸盐协助下进行30天的EK-BIO修复后，土壤中60％以上的金属和90％的POPs被清除。0.02 g / L的柠檬酸钠浓度被认为是合适的，因为较高的柠檬酸盐不会显着改善治疗性能，而会增加剂量消耗。柠檬酸盐增加了土壤电流和电渗流量。修复后，金属残留物主要以稳定且低毒的状态存在，可以有效降低有毒金属对周围环境和生物的潜在危害。EK-BIO处理影响土壤微生物数量，脱氢酶活性和群落结构。
