Abstract
The invention discloses surface layer composite soil for the ecological remediation of a refuse landfill, relates to a land reclamation technology, and solves the problems of high borrowed soil cost or plant nutrient deficiency in reclaimed soil of the currently adopted reclamation method, and the problem that landfill generated after household refuse is simply landfilled and industrial solid waste fly ash can cause the secondary pollution of an environment. The surface layer composite soil consists of the following components in percentage by mass: 25 to 55 percent of soil, 40 to 53 percent of refuse fertilizer and 2 to 25 percent of fly ash. The waste is recycled, the household refuse landfill can be prepared into the refuse fertilizer by a simple program, and the refuse fertilizer, the soil and the fly ash are prepared into the surface layer composite soil for the ecological remediation of the refuse landfill. The composite soil is easy to prepare and has wide raw material sources, a good waste recycling effect and good environmental benefits, economic benefits and social benefits.
Description
Technical field
The present invention relates to the land reclamation technology, is a kind of equivalent material that relates to refuse landfill restoration of the ecosystem mesexine soil specifically.
Background technology
The annual production of 2010 of China's domestic refuse has broken through 1.5 hundred million tons, and how the phenomenon of garbage-surrounded city is presenting, and garbage problem is very severe.Landfill disposal is the main disposal options of present domestic refuse, and the place of landfill waste is called as refuse landfill.Just need to close after landfill yard is filled up by rubbish, require this moment to carry out the restoration of the ecosystem of landfill yard at landfill yard surface coverage water-proof material or the surperficial earthing serike of landfill yard.In the high or Reclaimed Soil of the restoration of the ecosystem ubiquity soil moved in to improve the original cost of landfill yard, plant nutrition lacks or the low defective of plant survival rate.In addition, if the solid rejected fly ash of a large amount of garbage loading embeading things that produce after the simple and easy landfill disposal of domestic waste, industrial production discharging etc. mishandling, can cause the secondary pollution problem to environment.
Summary of the invention
The objective of the invention is provides a kind of top layer composite earth that is used for the refuse landfill restoration of the ecosystem simple, that the starting material source is wide, changing waste into resources is effective of making for the problems referred to above.
The present invention is comprised of soil, garbage tankage and flyash, and the mass percent of each component is soil 25%-55%, garbage tankage 40%-53%, flyash 2%-25%.
The best in quality per-cent of above-mentioned each component is soil 47.5%, garbage tankage 47.5%, flyash 5%.
Described soil is the refuse landfill Soil Surrounding, and indication flyash is the rejected fly ash that discharges in power plant or heat power plant's production process, and the indication garbage tankage is the garbage tankage that after consumer waste filling and embedding is processed, the garbage loading embeading thing of generation is made by simple program.
the garbage tankage that the garbage loading embeading thing that the present invention produces after the rejected fly ash that discharges in refuse landfill Soil Surrounding and power plant or heat power plant's production process and consumer waste filling and embedding are processed is made by simple program is made has certain nutrient and activity, be beneficial to landfill yard restoration of the ecosystem plant land the growth topsoil, thereby turn waste into wealth, the soil that can not only partly solve the refuse landfill restoration of the ecosystem lacks problem, solve the required plant nutrition problem of restoration of the ecosystem, and can make consumer waste filling and embedding thing and industrial solid rejected fly ash resource utilization, has good environmental benefit, economic benefit and social benefit.
Embodiment
Further illustrate the present invention below in conjunction with embodiment.
Embodiment 1: get the flyash of refuse landfill Soil Surrounding and power plant emission, and get the garbage loading embeading thing from landfill yard.The earth that fetches earth is neutral purple soil, and the garbage loading embeading thing is by the material of heap buried after for some time at household refuse landfill sites.The concrete making method that is used for the top layer composite earth of refuse landfill restoration of the ecosystem is:
(1) the garbage loading embeading thing is fetched back pkt. and is deposited, and the bag center material is adstante febre no longer, and after manually roughly selecting the thick matter such as wherein glass, plastics, gravel, wooden unit, then natural air drying crosses the 3mm sieve, obtains the raw material garbage tankage with the garbage loading embeading thing.The garbage tankage organic content is 15% left and right, and nitrogen content is 1.3% left and right, and phosphorus content is 0.3% left and right.
(2) with after soil, flyash natural air drying, cross respectively the 3mm sieve, obtain raw material soil and raw material powder coal ash.
(3) garbage tankage and raw material soil and raw material powder coal ash are mixed in proportion, through manually turning or the stirrer stirring, product after mixing is composite earth of the present invention, and wherein, the blending ratio of each component is soil 25%, garbage tankage 50%, flyash 25% by mass percentage.
Embodiment 2: the blending ratio of each component is soil 35%, garbage tankage 50%, flyash 15% by mass percentage.
The other the same as in Example 1.
Embodiment 3: the blending ratio of each component is soil 45%, garbage tankage 53%, flyash 2% by mass percentage.
The other the same as in Example 1.
Embodiment 4: the blending ratio of each component is soil 45%, garbage tankage 45%, flyash 10% by mass percentage.
The other the same as in Example 1.
Embodiment 5: the blending ratio of each component is soil 55%, garbage tankage 40%, flyash 5% by mass percentage.
The other the same as in Example 1.
Embodiment 6: the blending ratio of each component is soil 47.5%, garbage tankage 47.5%, flyash 5% by mass percentage.
The other the same as in Example 1.
Top layer of the present invention composite earth is carried out the potted plant test and is shown, soil, garbage tankage, flyash are mixed, the effect that flyash can play and regulate the composite earth granularity, increase the composite earth ventilation property, garbage tankage plays to be increased the composite earth nutrient and regulates organic effect, from Promoting plant growth, reduce raw material soil consumption, utilize the consumer waste filling and embedding thing and use on a small quantity the angle of rejected fly ash, being soil 47.5%, garbage tankage 47.5%, flyash 5% by mass percentage, is best proportioning.
The conventional using method of top layer of the present invention composite earth:
1. be used for the fulfiled assignment flowers and plants plantation in location of refuse landfill
In the location that household refuse landfill sites has fulfiled assignment, compacting, smooth good this location, then take the top layer composite earth as coverture, after covering certain thickness, as: 30-50cm; Can plant according to a conventional method flower, careless, water routinely and daily administration.
2. be used for the fulfiled assignment shrub plantation in location of refuse landfill
The location that compacting, smooth household refuse landfill sites have fulfiled assignment, take the top layer composite earth as coverture, after covering certain thickness, as: 50-60cm; Can plant according to a conventional method arbor, shrub, water in the usual way and daily administration.
3. for the restoration of the ecosystem after refuse landfill sealing
Refuse landfill after closing, compacting, smooth good landfill yard surface, take the top layer composite earth as coverture, after covering certain thickness, as: 50-60cm; Can plant according to a conventional method suitable arbor, shrub and woody plant, the plant of planting should be the pioneer plant of local suitable Environment of Rubbish Sites, waters in the usual way and daily administration.
