回灌型填埋场渗滤液泡沫消除问题的研究

STUDY OF ELIMINATING THE BUBBLE OF LEACHATE COMING FROM THE LANDFILL RECYCLED BY EACHATE

渗滤液水质水量变化大,有机物成分复杂,采用生化的方法泡沫问题难以解决,而单纯的物化方法成本又太昂贵,本实验采取回灌法,既最大化的应用了微生物消除了泡沫,又廉价的降低了COD;通过对准好氧填埋和厌氧填埋场渗滤液性质的比较,还得出厌氧填埋场的渗滤液可以缓解生化处理过程中产生的泡沫现象。

Leachate quality and quantity changes,and organic ingredients are complex.It is diffcult to resolve the bubble problem by biochemical.And the mothods of simple physical and chemical are far more expensive.Now takes the method of leachate recircled to the landfill.It is not only to maximize the application of the micro-organisms to eliminate the bubbles,but also inexpensive to reduced COD.By comparing the leachate coming from aerobic and anaerobic landfill,but also come to anaerobic landfill leachate can ease the bubbles in the process of biochemical treatment.
