The method is low in investment, easy to use and reliable in effect.
Description
Technical field
The present invention relates to the processing of application of city life garbage, be specifically related to a kind of bioremediation of application of city life garbage filtrate.
Background technology
Application of city life garbage is collected, is stored up, the leachate in processing treatment or landfill disposal process, and main component is water, dissolved organic matter, inorganic salt and heavy metal ion compound and pathogenic agent microorganism.Current advanced person's domestic refuse filtrate treatment process has following several:
(1) sewage work's biochemical oxidation method: after leachate is collected, be transported to sewage work with canned bottle and process.In fact, because containing a large amount of organic pollutants and heavy metal and pathogenic agent microorganism in leachate, strengthened Sewage Plant intractability, and processing costs is high, sometimes due to economic cost, causes a large amount of leachates to be thrown aside by hidden.
(2) burning method: canned after leachate is collected, concentrated with waste heat, through concentrated leachate, add in incinerator and burn.Existing garbage incinerating power plant is exactly this type of leachate treatment process adopting, and this type of leachate treatment process energy consumption is high, it is high to invest, cost is high, and has Pollution risk out of control.
(3) preparing active carbon method: canned after leachate is collected, concentrated with hot blast, add sponge, mix carbonization preparing active carbon.This type of leachate treatment process energy consumption is high, invests bigger than normally, and has larger Pollution risk out of control.
(4) microorganism treatment: with the microorganism species treating refuse filtrate of cultivating.This type of leachate treatment process investment working cost is high, less stable, and may there is biological hazard risk.
Day by day serious at application of city life garbage and leachate pollution hazard, even seriously go beyond in the situation of tolerance of people's quality of life, lower in the urgent need to a kind of investment, use leachate treatment process simple, reliable for effect.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiency of above-mentioned background technology, provide a kind of investment lower, use the bioremediation of application of city life garbage filtrate simple, reliable for effect.
The technical scheme that the present invention solves its technical problem employing is that a kind of bioremediation of application of city life garbage filtrate, comprises the following steps:
S1: the application of city life garbage filtrate of collection is placed in to agitated pool or stirred pot, under agitation adds heavy metal ion stablizer, stir, obtain mixture I; Again by mixture I continuously stirring 1～8 hour (preferably 2～3 hours);
S2: under continuously stirring, add rubbish deodorizing disinfectant in mixture I, continue to stir 15～60 minutes (preferably 20～40 minutes), obtain mixture II;
S3: add canebreak in mixture II, stir, obtain mixture III;
S4: by mixture III elimination clear water, obtain hygrometric state filter residue, hygrometric state filter residue is placed in to vermiculture level ground, shovel into the earth containing earthworm kind; Or mixture III is directly placed in to the soil containing earthworm, mixture III earthing is covered; Or mixture III is directly placed in to the culturing pool of spiral shell, freshwater mussel, loach, eel, as the feed ingredient of spiral shell, freshwater mussel, loach, eel.
Further, leachate described in step S1 is leaching vat and/or pressing filtering liquid.
Further, the mass ratio of the stablizer of heavy metal ion described in step S1 and leachate is 0.002～0.05: 1(preferably 0.005～0.025: 1, more preferably 0.01～0.02: 1).
Further, the mass ratio of rubbish deodorizing disinfectant and leachate described in step S2 is 0.002～0.05: 1(preferably 0.005～0.02: 1).
Further, the mass ratio of canebreak and leachate described in step S3 is 0.03～0.3: 1(preferably 0.05～0.1: 1).
Further, canebreak described in step S3 is any one or a few in straw bits, wheat straw, husk, cavings, vinasse.
Further, described in step S4, containing the earth of earthworm kind and the mass ratio of hygrometric state filter residue, be 0.08～2.0: 1(preferably 0.1～0.3: 1).
Compared with prior art, advantage of the present invention is as follows: the present invention utilizes heavy metal ion stablizer to kill harmful pathogenic agent microorganism and the parasite in leachate, and eliminates foreign odor and planar water soluble organism; Utilize organism and inorganic salt in earthworm digestion leachate, effectively treating refuse filtrate; The present invention investment is lower, it is simple, reliable for effect to use.
