A natural treatment system for the treatment of leachate was studied at Moskogen landfill in southern Sweden. This facility consists of three consecutive ponds and a soil-plant (SP)-system. A test area, receiving water from the third pond with the same hydraulic load as the SP-system, was used for estimation of the latter system. Quality parameters including biochemical oxygen demand, total organic carbon, ammonium, nitrate, orthophosphate, and total suspended solids along the treatment line were determined as well as soluble metals (Cu, Cd, Zn, Cr, Ni, and Pb). In addition a thorough investigation along the treatment line has also been performed concerning volatile organic compounds and semi-volatile organic compounds. Non-polar organic compounds were investigated using gas chromatography-mass spectrometry. Quantification was based on the assumption of equal response for the compounds found in comparison with the chosen marker substances. For polar, water-soluble compounds the measurements were restricted to phenolic compounds using high-performance liquid chromatography. Several different types of organic compounds were found in the raw leachate including aromatics, benzene-sulfonamides, biphenyls, naphthalene, organic phosphates, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, phenols and phthalates. The treatment system efficiently reduced organic pollutants, heavy metals, and nitrogen/phosphorous compounds. Most metals and organic compounds in the leachate were already significantly reduced to a low level in the treatment ponds and ammonium-N was efficiently transformed to nitrate-N in the SP-system.
在瑞典南部的莫斯科根垃圾填埋场对一种用于处理渗滤液的自然处理系统进行了研究。该设施由三个连续的池塘和一个土壤-植物（SP）系统组成。一个试验区域接收来自第三个池塘且与SP系统具有相同水力负荷的水，用于评估后一个系统。测定了沿处理流程的质量参数，包括生化需氧量、总有机碳、铵、硝酸盐、正磷酸盐和总悬浮固体，以及可溶性金属（铜、镉、锌、铬、镍和铅）。此外，还对沿处理流程的挥发性有机化合物和半挥发性有机化合物进行了全面调查。使用气相色谱-质谱法研究非极性有机化合物。定量基于与所选标记物质相比所发现化合物具有相同响应的假设。对于极性水溶性化合物，测量仅限于使用高效液相色谱法测定酚类化合物。在原渗滤液中发现了几种不同类型的有机化合物，包括芳烃、苯磺酰胺、联苯、萘、有机磷酸盐、多环芳烃、多氯联苯、酚类和邻苯二甲酸盐。该处理系统有效降低了有机污染物、重金属以及氮/磷化合物。渗滤液中的大多数金属和有机化合物在处理池塘中已显著降低至低水平，并且铵态氮在SP系统中有效地转化为硝态氮。
