用化学絮凝法处理垃圾渗滤液的试验研究

Studying on the Landfill Leachate by the Method Flocculation.

针对垃圾渗滤液在不同季节里 ,因产生量、浓度变化大而造成渗滤液难于处理的特点 ,在生化法处理的基础上用化学絮凝法处理垃圾渗滤液。在试验方案中选用不同出水水质 ,以探求最佳工艺特点、CODcr值与投药量的关系。结果证实 ,用化学絮凝法处理渗滤液对降低CODcr值、总磷、脱色是行之有效的。

In view of the characteristic of difficuties in leachate design and treatment made by different leachate output and concentration varying with seasons,we have carried out research on landfill leachate by flocculation based on the method by biochemiatry.In this paper,we draw up different experience programs according to different water qualities to pursue the best technology process and the relation between the value of COD cr and the amount of drug.It's concluded that using flocculation to disoose landfill leachate is effective on decrasing the calue of COD cr ,the total phosphorus and chromaticity.
