Yet, along with socioeconomic sustained and rapid development, the Sanitary Landfill Technology exposed day by day of domestic waste its limitation: 1. refuse landfill floor space is big, and landfill yard addressing difficulty has become universal phenomenon.2. need a large amount of overburden soils source, not only consume a large amount of land resources, and reduced the effective storage of refuse landfill to a great extent.3. the garbage loading embeading operation has had a strong impact on peripheral ecoscape, and the surface revegetation of landfill yard end is slow.At present, the landfill yard revegetation slowly causes a large amount of land resource of refuse landfill idle, has caused the serious waste of land resource.4. because large tracts of land landfill soil is exposed idle, and soil water retention power is poor, lack the bifurcated characteristic of removing contamination, cause percolate from garbage filling field output to increase, foul gas directly is discharged in the atmosphere, has become the important pollution sources of surrounding area water environment and atmospheric environment.Therefore, the quick recovering vegetation of refuse landfill has become one of problem in science of the key that current urgent need solves.
The at present domestic perfect technical scheme relevant with the vegetation in garbage landfill field recovery yet there are no report.Mainly contain the problem urgent need solution that following obstruction vegetation in garbage landfill field recovers: 1. refuse landfill earthing fertility is poor; 2. the refuse landfill earthing is overstocked through the mechanical ramming porosity, and retention ability is poor; 3. refuse landfill earthing earth oxygen content is low, and the temperature height is to the toxic effect of root system of plant; 4. refuse landfill earthing resource scarcity; 5. the vegetation in garbage landfill field recovering process is slow.
Summary of the invention
The objective of the invention is to recover slowly for solving vegetation in garbage landfill field, the large tracts of land idle land is exposed, landscape ecological destroys serious, and the problems such as pollution of bringing for atmosphere and water environment, and a kind of method of utilizing municipal sludge modified covering soil to recover vegetation in garbage landfill field is provided.
Utilize municipal sludge modified covering soil to recover the method for vegetation in garbage landfill field, may further comprise the steps:
1) with the mud of municipal wastewater treatment plant as refuse landfill earthing modifying agent, after in mud, adding conditioner, evenly mix with earthing again and obtain improveing earthing, the percentage by weight of conditioner in mud is 5-15%, and the percentage by weight of mud in the improvement earthing that has added conditioner is 5-20%;
2) will cover refuse landfill earthing top layer through the improvement earthing that step 1) is handled, leveling must compacting, and plantation can adapt to the patience adaptive plant of refuse landfill environment then.
Among the present invention, said conditioner can be a mushroom residue, wood chip, pecan shell or tealeaf residue etc.
Consider the plantation survival rate of plant and economize on soil that the thickness that generally makes the improvement earthing cover refuse landfill earthing top layer is 15-30cm.
The patience adaptive plant of plantation can select for use locality or this locality can resist the plant that landfill gas is coerced; Select plant for use with stronger drought resisting, heat resistanceheat resistant, diseases and insect pests resistance; Select the plant that surrounding environment is had strong adaptive capacity for use; Select operational management plant easily for use; Select the high plant of comprehensive utilization value for use; Select for use and have the plant of beautifying landscape function.
Beneficial effect of the present invention is:
Because the present invention has covered one deck improvement earthing on refuse landfill earthing top layer, earthing fertility, porosity and moisture holding capacity have been improved, through the patience adaptive plant of plantation adaptation refuse landfill environment, can obviously accelerate the recovery of vegetation in garbage landfill field, shorten the revegetation process; Solved that present refuse landfill large tracts of land soil is exposed to be fallen into disuse, earthing resource anxiety, environmental pollution and landscape ecological destroy problems such as serious, save a large amount of land resources, produce tangible economic benefit.
The specific embodiment
Embodiment
With the mud of municipal wastewater treatment plant as refuse landfill earthing modifying agent, after in mud, adding mushroom residue, evenly mix obtaining improveing earthing again with earthing, the percentage by weight of mushroom residue in mud is 5%, and the percentage by weight of mud in the improvement earthing that has added mushroom residue is 10%.To improve earthing and cover refuse landfill earthing top layer, the thickness that the improvement earthing covers refuse landfill earthing top layer is 20cm, leveling must compacting, then according to the adaptive cropping pattern of " arbor+shrub+draft ", be sprinkled into india lovegrass and Festuca Arundinacea grass-seed earlier, introduce a fine variety patience adaptive plant wet-land pine tree, coral Piao, photinia glabra, cercis again, according to (0.75 * 0.8) m
2Carry out adaptive plantation, landscape design, the upper strata plant is wet-land pine tree and coral Piao, and the middle level is photinia glabra and cercis, and understory is Festuca Arundinacea and india lovegrass.Upper strata plant wet-land pine tree is the aciculiform aiphyllium, and coral Piao is the evergreen broad-leaved arbor, and the wealthy collocation of pin brings out the best in each other; The middle level photinia glabra is newly red as fire slightly spring, and very grand, cercis is not only tree-like good-looking, and leave pale reddish brown also quite gorgeous; Understory india lovegrass and Festuca Arundinacea grow green and fresh, and landscape ecological has obtained good recovery.Revegetation through 1 year, the multiple green area of refuse landfill reaches more than 90%, and the revegetation process is obviously accelerated, and shortens the time of reclaiming more than at least one year, has solved the ubiquitous revegetation process of a present refuse landfill difficult problem slowly.The improving sludge earthing has obviously promoted the growth (seeing Table 1) of plant.Adopt the inventive method to recover vegetation in garbage landfill field, overburden layer can be saved a large amount of land resources by the thick 60cm that is reduced to of 100cm before the improvement, if by saving 40cm earthing, 20 yuan/m
