堆填区的运作会因废物分解而产生渗滤液，因而造成环境问题。齐帕永垃圾填埋场设有一个渗滤液处理厂，使用稳定池。本研究的目的是评估齐帕永垃圾填埋场稳定池的性能。数据分析基于2017年4月至5月雨季条件下处理单元进出水的渗滤液样品。结果显示，根据温度34.81°C、总悬浮固体（TSS）72.33 mg/L、pH 7.83、生化需氧量（BOD）3，959.63 mg/L、化学需氧量（COD）6，860 mg/L、总氮373.33 mg/L和重金属汞0.0016 mg/L等参数得出的平均渗滤液质量。该处理厂的出水水质超过了印度尼西亚环境和林业部2016年第59号法律规定的渗滤液标准限值。设计评价结果表明，厌氧池、兼性池和成熟池系统不符合设计标准。因此，需要改进设计，以提高渗滤液处理厂的性能，并确保排放到水体中的渗滤液不超过标准限值，以防止污染环境。
The operation of landfill can cause environmental problems due to waste decomposition in the form of leachate production. Cipayung Landfill has a leachate treatment plant using stabilization ponds. The objective of this research is to evaluate the performance of stabilization ponds at Cipayung Landfill. The data were analyzed based on leachate samples from treatment unit’s influent and effluent under rainy season condition from April to May 2017. The results show the average leachate quality based on parameters of temperature by 34.81°C, Total Suspended Solid (TSS) of 72.33 mg/L, pH of 7.83, Biochemical Oxygen Demand (BOD) of 3,959.63 mg/L, Chemical Oxygen Demand (COD) of 6,860 mg/L, Total Nitrogen of 373.33 mg/L, and heavy metal Mercury of 0.0016 mg/L. The treatment plant’s effluent quality exceeds the leachate standard limit based on Indonesia’s Ministry of Environment and Forestry Law No. 59 of 2016. The results of design evaluation show that the anaerobic pond, facultative pond, and maturation pond system do not meet the design criteria. Therefore, a design improvement is needed to increase the performance of the leachate treatment plant and to ensure that the leachate discharged to water bodies does not exceed the standard limit to prevent contamination of the environment.
