Abstract:

According to the characteristic of the municipal landfill leachate, the leachate can be purified through coagulation sedimentation-sequencing batch reactor treatment. Depending on the experiment, the optimal deposit agent and the optimal process conditions are confirmed. The result indicates that through the coagulation sedimentation treatment, the leachate can be transformed into a kind of wastewater, which is suitable for the further treatment in the sequencing batch reactor. After above treatments, the effluent can meet the national discharge standard. This method is economical and practical for our country.

Key words: landfill, leachate, coagulation sedimentation, sequencing batch reactor

摘要：

针对城市填埋场渗滤液的特点，采取了先混凝后生化的处理方法。在混凝试验中确定了适合垃圾渗滤液处理的最佳混凝剂并通过条件试验确定了使用该混凝剂处理垃圾渗滤液的最佳工艺条件。试验结果表明：对垃圾渗滤液采用先混凝后生化的方法是一种经济实用适合我国国情的垃圾渗滤液处理方法，经该工艺处理的垃圾渗滤液各项指标可达国家规定的排放标准。
