A kind of biological reaction apparatus that can accelerate consumer waste filling and embedding stabilisation process comprises leachate recirculation system and landfill reactor, and described leachate recirculation system comprises the leachate collection pond, water pump and some water inlets and water-drainage tube part.
Described landfill reactor comprises sour cushion and lays respectively at the upper and lower consumer waste filling and embedding layer I of sour cushion and consumer waste filling and embedding layer II that described sour cushion is the consumer waste incineration residue.The thickness of described sour cushion is 1: 4～6 with the gross thickness ratio of two consumer waste filling and embedding layers.
Described sour cushion can be laid drainage type geotextile up and down, guarantees the structural stability of sour cushion.
As a kind of preferred, above described consumer waste filling and embedding layer II, be provided with the fine sand cover layer, the even anaerobic environment that distributes and guarantee the landfill body of the percolate of being convenient to recharge.
The top of described landfill reactor also is provided with air chamber, and air chamber is positioned at fine sand cover layer top, and what be convenient to landfill gas falls to arrange a mouthful discharge from gas.
The bottom of described landfill reactor is provided with metalling, and described metalling is that particle diameter is the gravel of 10-40mm, is convenient to discharging and the collection of percolate.
The thickness of described fine sand cover layer and metalling is 5～10cm.
The top of described landfill reactor is provided with percolate water inlet and gas guide mouth.
When apparatus of the present invention are used, lay metalling at reactor bottom, consumer waste filling and embedding layer I inserted in the metalling top, and constantly compacting, reaches the requirement of the effective landfill height of reactor up to thickness.Consumer waste filling and embedding layer I lays sour cushion in the top, and constantly compacting makes its thickness reach the requirement of the effective landfill height of reactor.Acid cushion top is inserted house refuse again, and constantly compacting, reaches the requirement of the effective landfill height of reactor up to consumer waste filling and embedding layer II.Then, sealed reactor after laying the fine sand layer above the consumer waste filling and embedding layer II.When operation device enters percolate in the leachate collection pond by valve, treats that leachate collection finishes, the be correlated with mensuration of physical and chemical index of the percolate sample that takes a morsel, investigation biological reaction apparatus ruuning situation.Remaining percolate adopts water pump to recharge to landfill reactor.
The present invention arranges sour cushion on the basis of recharging type landfill biological reaction apparatus, not only can increase the moisture content of rubbish body, improve activation of microorganism, and can utilize in the calcic class material in the sour cushion and the acidic materials in the landfill yard initial operating stage percolate, the acid of alleviating the landfill yard initial operating stage suppresses phenomenon, improve better p H environment for microorganism, accelerate the degraded of rubbish, accelerate consumer waste filling and embedding stabilisation process.

The specific embodiment
Embodiment 1
A kind of biological reaction apparatus that can accelerate consumer waste filling and embedding stabilisation 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 inlet 8, and the inside of landfill reactor is provided with fine sand cover layer 6, consumer waste filling and embedding layer II 5, sour cushion 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 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 residue (sour cushion 4) in the top, and constantly compacting makes its thickness reach 20% of the effective landfill height of reactor.Acid cushion 4 tops are inserted house refuse again, 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 cover layer 6 back sealed reactors.Percolate water inlet 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 ruuning situation.Remaining percolate adopts water pump 10 to recharge to landfill reactor.
Fig. 2 is the refuse landfill of employing apparatus of the present invention 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 residue acid cushion, the pH value of its percolate rose to about 7.5 at 150 days after the slow a period of time of rising, and kept this level subsequently always.This numerical value is similar to the pH value of the refuse landfill of maturation 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 apparatus of the present invention 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 downward trend in the percolate from garbage filling field of consumer waste incineration residue acid cushion 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 stabilisation level far away.
The variation tendency of comprehensive pH and DOC as can be seen, the refuse landfill operation that contains consumer waste incineration residue acid cushion reached stable status in about 150 days substantially, and pure refuse landfill operation is stable yet after 230 days.This shows, the stabilisation process that the sour cushion that constitutes with the consumer waste incineration residue 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 resource.
