Title
(EN) WASTE PERCOLATE TREATMENT METHOD
(FR) PROCÉDÉ DE TRAITEMENT D'UN PERCOLAT DE DÉCHETS
(ZH) 垃圾渗滤液的处理方法
Abstract
(EN)
A waste percolate treatment method, comprising the following steps: ammonia nitrogen removal, flocculation precipitation, electrolysis, capacitive desalination, anaerobic treatment, aerobic treatment, membrane filtration, and membrane concentrated solution treatment. The present treatment method has a stable operation due to the combination of the electrolysis technique, the membrane technique, and the organic technique, has high treatment efficiency, and lowers the indicators of ammonia nitrogen, COS, SS, and color in the waste percolate, so that the outputted water meets discharge requirements.
(FR)
L'invention concerne un procédé de traitement d'un percolat de déchets, comprenant les étapes suivantes : élimination d'azote ammoniacal, précipitation par floculation, électrolyse, dessalage capacitif, traitement anaérobie, traitement aérobie, filtration sur membrane et traitement de solution concentrée sur membrane. L'avantage de la présente invention est que la technique par électrolyse, la technique à membrane et la technique organique sont combinées pour se compléter l'une l'autre, formant par là un procédé de traitement de percolat de déchets qui a un fonctionnement stable, un faible coût, un rendement de traitement élevé, qui est adaptable à différentes qualités d'eau et qui peut diminuer les indicateurs d'azote ammoniacal, de COS, de SS et de couleur dans le percolat de déchets de telle sorte que l'eau déchargée satisfasse les exigences.
(ZH)
一种垃圾渗滤液的处理方法,包括如下步骤:脱氨氮、絮凝沉淀、电解、电容脱盐、厌氧处理、好氧处理、膜过滤和膜浓缩液处理。该处理方法通过电解工艺、膜工艺和生化工艺的结合,运行稳定,处理效率高,能有效降低垃圾渗滤液中氨氮、COD、SS、色度等指标,使出水达标排放。
