Abstract: PURPOSE: A COD(chemical oxygen demand) reducing technology for leachate from a reclamation site using biological treatment is provided to greatly reduce COD by using bacteria producing lignin decomposition and/or oxidation enzyme. CONSTITUTION: Using bacteria having lignin decomposing enzyme or oxidizing enzyme like monoxidase or dioxidase, lignin and cyclic compounds containing halogen, which are hardly decomposed under normal condition, are easily decomposed to reduce COD. The treated bacteria grow well without adding no nutrient in the leachate. Intake and decomposition by the bacteria reduce COD value and lower nutrients in the leachate.

Abstract translation: 目的：提供使用生物处理从填埋场渗滤液的COD（化学需氧量）减少技术，通过使用细菌生产木质素分解和/或氧化酶大大降低COD。 构成：使用具有木质素分解酶或氧化酶如单氧化物酶或氧化酶的细菌，在正常条件下难以分解的含有卤素的木质素和环状化合物容易分解以降低COD。 经处理的细菌生长良好，不会在渗滤液中添加营养物质。 细菌的摄入和分解降低了COD值，降低了浸出液中的营养。
