Background technology
Along with industrial expansion and Increase of population, the refuse treatment problem becomes increasingly conspicuous.Not only contain a large amount of organic pollutants in the garbage leachate, and contain the holophytic nutrition thing of heavy metal and high density.Undressed garbage leachate is soil and water system around the severe contamination, and may enter human body by food chain, is detrimental to health.At present, also there are not system and proven technique treating refuse to ooze drop liquid.Method commonly used has activated sludge method treatment system (conventional activated sludge method, AO method, OA method, AB method, oxidation ditch process etc.), biomembrance process treatment system, stabilization pond and land treatment system.Adopt the aforesaid method treating refuse to ooze drop liquid, not only floor space is big, equipment and working cost height, and the breakdown rate height, and also comprehensive treatment effect is stable inadequately.
Summary of the invention
Technical problem to be solved by this invention is, a kind of method and resource product that utilizes the microbiobacterial agent treating refuse to ooze drop liquid is provided, its effectively treating refuse ooze the hazardous and noxious substances in the drop liquid and generate the liquid fertilizer can be directly used in irrigation.
Technical scheme of the present invention is, a kind of method and resource product that utilizes the microbiobacterial agent treating refuse to ooze drop liquid is provided, and this method may further comprise the steps: (a) add trophoplasm in garbage leachate; (b) in garbage leachate, add microbiobacterial agent; (c) to garbage leachate gap aeration; (d) allotment is through the fertilizer efficiency of the liquid of above-mentioned steps processing.
The aforesaid method of utilizing the microbiobacterial agent treating refuse to ooze drop liquid, microbiobacterial agent are added in after adding trophoplasm 12-36 hour.
The aforesaid method of utilizing the microbiobacterial agent treating refuse to ooze drop liquid, described allotment fertilizer efficiency step is for adding inorganics phosphorus, potassium.
The aforesaid method of utilizing the microbiobacterial agent treating refuse to ooze drop liquid, described trophoplasm comprises dipotassium hydrogen phosphate.
The aforesaid method of utilizing the microbiobacterial agent treating refuse to ooze drop liquid, handling total time is 120 hours.
The aforesaid method of utilizing the microbiobacterial agent treating refuse to ooze drop liquid, the pH value of garbage leachate is 7-8.5 behind the interpolation trophoplasm.
The present invention also provides a kind of resource product that utilizes the microbiobacterial agent treating refuse to ooze drop liquid, and heavy metal and organism that it utilizes in the microbiobacterial agent removal garbage leachate are converted into organic liquid fertilizer with garbage leachate.
The aforesaid resource product that utilizes the microbiobacterial agent treating refuse to ooze drop liquid, its treating processes may further comprise the steps: (a) add trophoplasm in garbage leachate; (b) in garbage leachate, add microbiobacterial agent; (c) to garbage leachate gap aeration; (d) allotment is through the fertilizer efficiency of the liquid of above-mentioned steps processing.
Utilize method of the present invention, can remove the hazardous and noxious substances in the garbage leachate, keep the fertilizer efficiency composition that oozes in the drop liquid simultaneously, black smelly garbage leachate is converted into efficient composite fluid organic fertilizer, can be used as water source for irrigations such as indoor and outdoor ornamental plant, forestry, lawn.
Description of drawings
To be that the present invention is a kind of utilize the microbiobacterial agent treating refuse to ooze the method for drop liquid and the process flow diagram of resource product to Fig. 1.
Embodiment
Make garbage leachate flow into an even matter pond, and in even matter pond, add the trophoplasm of phosphoric acid hydrogen dipotassium, the pH value of garbage leachate is adjusted to 7～8.5.Threw in trophoplasm 20-28 hour, and made with the well-mixed garbage leachate of trophoplasm and flow into an acidolysis pond.Adding in the acidolysis pond according to Patent Office of the People's Republic of China's application number be the complex micro organism fungicide of the patent application gained of " 01127096.6 ", and thread fungus that described complex micro organism fungicide by photosynthetic bacteria, milk-acid bacteria, actinomycetes, fermentation is and bacillus aceticus etc. are formed.Under the trophoplasm effect, microbiobacterial agent is fully bred.Through 40-56 hour, make the garbage leachate that contains microbiobacterial agent flow into a biochemistry pool.In this biochemistry pool, adopt the mode of gap aeration to make microbiobacterial agent decompose hazardous and noxious substances in the garbage leachate to garbage leachate.Biochemical reaction 40-56 hour, under the microbiobacterial agent effect, ooze heavy metal precipitation in the drop liquid to biochemistry pool bottom, ooze the NH in the drop liquid
3-N removes more than 70%, and COD removes more than 50% simultaneously.The effective ingredient of oozing in the drop liquid includes with then fully reservation of microorganism.At this moment, the pH value that oozes drop liquid is 6.5-7.At last, make the garbage leachate of handling through above-mentioned steps flow into a preparing pool,, add inorganicss such as phosphorus, potassium, make and ooze drop liquid and be converted into the composite fluid organic fertilizer according to the ratio of each composition in the preparing pool.Through the processing of this step, the content of each composition is as shown in the table in the garbage leachate:
| Contained material | Content |
| Total phosphorus (P 2O 5) | 100-200PPM |
| Total nitrogen (N) | 1000-2000PPM |
| Total potassium (K 2O) | 100-200PPM |
| Iron (Fe) | 50-100PPM |
| Coliform group count | ≤ 6/L |
| Mercury and compound thereof | ≤0.005PPM |
| Cadmium and compound thereof | ≤0.5PPM |
| Arsenic and compound thereof | ≤0.5PPM |
| The sexavalence chromium compounds | ≤0.5PPM |
| Lead and compound thereof | ≤1.0PPM |
| Copper and compound thereof | ≤1.0PPM |
Garbage leachate through above step process has reached agricultural filling standard, can be directly used in irrigation.
Above-mentioned four ponds water successively connect, and the processed drop liquid that oozes enters next pond in the effect of waterhead from a pond, and are oozed the residence time of drop liquid in each pond by waterhead control.Above-mentioned each pond does not all have particular requirement.
In another embodiment of the present invention, trophoplasm and microbiobacterial agent are added in the garbage leachate simultaneously, make microbiobacterial agent fully breeding under the trophoplasm effect.Through 60-80 hour, make garbage leachate flow into biochemistry pool.In biochemistry pool, to garbage leachate gap aeration.Under microbial process, the heavy metal precipitation in the garbage leachate is to the biochemistry pool bottom, and the NH more than 70%
3-N is decomposed, and COD removes more than 50% simultaneously.When the pH value that oozes drop liquid is reduced to 6.5-7, make garbage leachate flow into preparing pool, and, make garbage leachate be converted into the composite fluid organic fertilizer according to oozing each components in proportions allotment fertilizer efficiency in the drop liquid.
