Embodiment
Embodiment 1
A kind of biological reaction apparatus that can quicken consumer waste filling and embedding stabilization process as shown in Figure 1, comprise leachate recirculation system and landfill reactor, described leachate recirculation system comprises water pump 10, leachate collection pond 11, percolate discharge guiding pipe 12 and valve 13, described landfill reactor comprises housing 1, the landfill reactor top is provided with gas guide mouth 9 and percolate water-in 8, and the inside of landfill reactor is provided with fine sand tectum 6, consumer waste filling and embedding layer II 5, sour buffer layer 4, consumer waste filling and embedding layer I 3 and metalling 2 from top to bottom successively.
Before the device operation, lay metalling 2 in the landfill reactor bottom earlier, be convenient to the discharging and the collection of landfill percolate.Consumer waste filling and embedding layer I inserted in metalling 2 tops, and constantly compacting, reaches 40% of the effective landfill height of reactor up to thickness.Consumer waste filling and embedding layer I lays consumer waste incineration resistates (sour buffer layer 4) in the top, and constantly compacting makes its thickness reach 20% of the effective landfill height of reactor.Acid buffer layer 4 tops are inserted domestic refuse once more, and constantly compacting, reach 40% of the effective landfill height of reactor up to consumer waste filling and embedding layer II.Then, above consumer waste filling and embedding layer II, lay fine sand tectum 6 back sealed reactors.Percolate water-in 8 and water pump 10, leachate collection pond 11, leachate collection pond 11 is connected with the landfill reactor bottom by percolate discharge guiding pipe 12, valve 13.
During the device operation, open valve 13 every day, percolate is entered in the leachate collection pond 11 by percolate discharge guiding pipe 12.Treat that leachate collection finishes, the be correlated with mensuration of physical and chemical index of the percolate sample that takes a morsel is investigated biological reaction apparatus running condition.Remaining percolate adopts water pump 10 to recharge to landfill reactor.
Fig. 2 is the refuse landfill of employing the utility model device and the percolate pH value variation comparison diagram of pure household refuse landfill sites.
As seen from Figure 2, the change procedure of two landfill yard reactor percolate pH is consistent substantially initial 80 days of operation, then presents distinct variation tendency afterwards.The landfill yard that contains consumer waste incineration resistates acid buffer layer, the pH value of its percolate rose to about 7.5 at 150 days after the slow for some time of rising, and kept this level subsequently always.This numerical value is similar to the pH value of sophisticated refuse landfill basically, illustrates that landfill yard has been in comparatively stable status.For pure household refuse landfill sites, the pH value of its percolate is in a process that slowly rises always, and its percolate pH value still maintains about 6.5 after 230 days in operation, reaches the level of ripe refuse landfill far away.
Fig. 3 is the refuse landfill of employing the utility model device and the percolate DOC value variation comparison diagram of pure household refuse landfill sites.
As seen from Figure 3, the change procedure of two landfill yard reactor percolate DOC and the variation tendency basically identical of pH.Contain that DOC presents comparatively significantly downtrending in the percolate from garbage filling field of consumer waste incineration resistates acid buffer layer after pH is increased to 7.5, move after 230 days, its DOC concentration drops to 2800mg/L and kept stable by the highest 22000mg/L, the DOC value basically identical of this value and ripe refuse landfill.Pure refuse landfill is after operation 230 days, and its DOC concentration still maintains about 20000mg/L, reaches the stabilization level far away.
The variation tendency of comprehensive pH and DOC as can be seen, the refuse landfill operation that contains consumer waste incineration resistates acid buffer layer reached stable status in about 150 days substantially, and pure refuse landfill operation is stable yet after 230 days.This shows, the stabilization process that the sour buffer layer that constitutes with the consumer waste incineration resistates can be accelerated landfill yard significantly is set in the landfill yard, thereby increase the storage capacity of refuse landfill, this is significant for the rare China of land resources.
