| 摘 要： | 采用室内土壤柱实验装置,研究了以生物分解性塑料为反硝化碳源去除水中的硝酸盐.结果表明,以PHB为反硝化碳源,能有效去除水中的硝酸盐,最高去除率达到100%.实验结束后,PHB的重量从实验开始的40 g经73 d降到18.6 g,原有光滑的PHB表面变成粗糙,说明PHB作为碳源被反硝化菌所利用.随着时间的推移,出水的TOC浓度与进水的TOC浓度相当接近,出水的TOC浓度基本稳定在5 mg/L以内,说明PHB的碳释放量具有可控性,不易造成二次污染.

| Abstract: | The removal of nitrate in groundwater using biodegradable plastic as carbon resource in denitrification was studied by indoor soil column.The result showed the nitrate in groundwater was removed effectively using PHB as carbon resource in denitrification and the maximal removal rate reached 100%.The weight of PHB was decreased from original 40g to 18.6g after 73 days when the experiment was finished and the smooth surface of PHB became rough,which proved that the PHB was used as carbon resource by denitrifi... |
