Description
Technical field
The present invention relates to percolate from garbage filling field collection technique, more particularly to a kind of percolate for refuse landfill
Collection system and its construction method.
Background technology
Percolate caused by the household refuse landfill sites of relatively early a collection of concentration landfill domestic at present progresses into aging rank
Section, is mainly shown as raw water CODcr（COD）It is relatively low, ammonia-nitrogen content is high, biodegradability is poor, carbon-nitrogen ratio ＜ 2 etc., sternly
Ghost image rings stable operation and the landfill disposal effect of biochemical system.Each refuse landfill starts to take in garbage loading embeading operation field
The mode of recharge collects high concentration percolate to improve influent quality.
During leachate recirculation, because each landfill yard land-fill method is unreasonable and leads the reasons such as the system of oozing is not smooth,
Development is digged pit on landfill yard rubbish surface takes the mode of percolate to collect percolate with pumping.During leachate recirculation,
With the increase of recharge water, the diafiltration liquid measure in leachate collection hole increases therewith, because pump is opened not in time, or loose rubbish
The reasons such as rubbish floating, a large amount of percolates flow into junk-heap body surfaces, not only reduce leachate collection efficiency, while add rubbish
The humidity of rubbish heap body, rubbish shatter value is improved, rubbish floating is exacerbated, so as to block pumps.
The content of the invention
The technical problem to be solved in the present invention is overcome the deficiencies in the prior art, there is provided a kind of simple and reliable for structure, diafiltration
Liquid collection efficiency is high, can reduce the leachate collection system for refuse landfill of pump blocking frequency.
