Abstract
The invention relates to a processing method for the solid waste, wherein an ecology inert type landfill site is built to process the solid waste. The technical proposal of the invention is to satisfy two conditions at the site selection: one is the relative position is higher, and the other one is the depth of excavation is not lower than the water table. The invention makes the garbage in the relatively dry state by effectively reducing the natural rain water into the dustheap and no margin water exosmosis in the garbage landfill, thereby rigidly controlling the rubbish pollution range restricted to the inside of the landfill without polluting the external environment.
Description
Invention field
The present invention relates to the processing method of solid waste, build a kind of refuse landfill of ecological safety type and handle solid waste.
The invention still further relates to the refuse landfill of handling solid waste.
Background of invention
Garbage environment pollution is a global significant problem, the improper sustainable development that will have a strong impact on ecological safety and society of garbage disposal, and countries and regions especially underdeveloped are more outstanding.Trash processing way generally has three kinds at present: burning, sanitary landfills and compost.
The sanitary landfills of rubbish be the centralized treatment of urban garbage of present China main mode [Du Jiajing, Wang Fengqing. Design of Valley-Type Landfill Site is inquired into. environmental hygiene engineering .2005, (3) 53～54.].The step of building refuse landfill comprises addressing, design, steps such as excavation, antiseepage processing, landfill, covering.Existing refuse landfill addressing all is on the level land or the valley floor, and therefore, landfill yard is subjected to underground water inevitably, and the infiltration of rainwater etc. causes the pollution to the landfill yard surrounding enviroment, and is serious even can produce underground water source and pollute.The most headachy problem is the processing of garbage leachate in the design and running management of refuse landfill, has proposed many methods how the disposal of refuse landfill yard oozes drop liquid in the prior art, for example CN200410016079.3.Because garbage leachate water quality composition is extremely complicated, and water quality and quantity is subjected to that the variation, weather of landfill yard service life and rubbish composition etc. are multiple to be difficult to the factor affecting of artificial control and to change in very big amplitude range, and this gives determining of the process choice of oozing drop liquid and handling, design parameter and operational management brings great difficulty.
On the other hand, also there is people (CN02145261.X) to propose to eliminate vertical rain penetration in the prior art, makes rainwater and sewage separation with the method for coverlay.Though this has reduced the amount that enters the water in the refuse landfill, rainwater can be stoped owing on landfill yard, cover, but underground water can not be stoped, therefore still need handle and ooze drop liquid.Simultaneously, also not environmental protection of the film that is covered itself is unfavorable for setting up good ecological environment in refuse landfill.
Summary of the invention
The present invention is directed to conventional garbage landfill yard construction method and have the insurmountable drop liquid problem of oozing, propose a kind of brand-new method of building refuse landfill.
Technical scheme of the present invention is when addressing, satisfies two conditions, the one, and relative position is higher; The 2nd, cutting depth is not less than level of ground water.
Traditional refuse landfill all is to build on the level land or low-lying place.The present invention proposes refuse landfill and builds on the highland that can not suffer flood harm, top, for example hillside fields, or massif.For economical operation, easy to operate, preferably select the gradient less nearby, and can lead to the mountain region of haulage vehicle, or select the terraced fields that will concede the land to forestry for use.Such addressing has solved the big problem of refuse landfill polluted underground water.
Simultaneously, consider the gradient of selected location, build barricade in the lower side of landfill yard or around whole landfill yard.Build barricade at the lower edge of relative position, selected place two effects arranged: the one, the scope of control garbage loading embeading, as with the line of demarcation of environment outside the venue; The 2nd, help increasing the degree of depth of garbage loading embeading, because the downward pressure that weight produces, and prevent the rubbish landslide to bear rubbish in the landfill yard, the structure of barricade is decided according to the concrete landform of the landfill yard of being built.The barricade in soot is different with general straight retaining wall, and on the spot position and profile change and change according to site topography, can have complications and height to change.The barricade material preferably selects for use the nature scree to build, raise as higher maybe need the continuation of barricade, then should be according to the needs of engineering safety, adopt reinforced concrete pile, beam and plate to reinforce, the tor of best natural imitation circle of profile of barricade, make every effort to make a distinction between the important and the lesser one, height is in picturesque disorder, can become the view with certain artistic appeal.In addition, in order to reduce construction costs, barricade also can adopt easy Tu Shan to replace, but must take the necessary engineering measure that prevents the Tu Shan landslide.Barricade also can adopt native stone in conjunction with construction, mild part soil, precipitous part stone.
Before the inherent heap garbage in field, the table soil that will have certain fertility forwards the both sides of dumping part to, makes to cover the standby soil and the plantation soil of rubbish.The order of digging is progressively to dig commentaries on classics at the bottom of the mountain on the mountain, and the degree of depth of digging must preferably be no more than 1m more than level of ground water, and width is decided according to the quantity of refuse of landfill, can be wide can be narrow.The table soil of digging can be used to enclose the hole temporarily and be scattered to both sides to stop rubbish before rubbish is not piled design height.
If the place is milder mountain region, rubbish can directly be transported to interior a stacking; If the place gradient is bigger, then can select a higher position, conveyer is installed, utilize conveyer belt that rubbish is gone to and stack the place.After the dumping, the biologic garbage in the rubbish heap easily produces a large amount of biogas and forms potential safety hazard in the environment of anaerobism, therefore, before dumping, must the guide tracheae be installed earlier, for example adopts the filter pipe of DN100mm, per 15～20m
2Install one, and notice that control rubbish blocks blast pipe in the process of rubbish Bian Dui limit compacting, the biogas that rubbish heap is produced in time is discharged into out-pile.In the dumping process, should in time the rubbish of having stacked be covered with film or other coverings, a rainwash of managing to stack the some top draws away, and pollutes environment and underground water outside the venue to prevent rainwater from infiltrating in the rubbish heap, and remaining does not have bulk water more than needed and exosmose in the rubbish heap.
In dumping to design height, the table soil of digging in both sides is covered on the rubbish heap, and it is banded that the soil that will cover is organized into ladder, the ladder band is made up of alternate table top and inclined-plane, surface slope is 25～35 °, and surface width generally must not surpass 5 meters, and the less regional inclined-plane of rainfall can be narrow, otherwise the inclined-plane can be wide.But the width of each table top is advisable with 1-3 meters.
Formed tableland behind the whole ground of earthing utilizes table top optionally to plant indigenous plant in case the forest ecology view is built in soil erosion.Characteristics such as green tree species possesses preferably that antipollution is drought-resistant, salt tolerant alkali and anti-low level management are as trees such as black pine, Cong Zhu, Chinese tallow tree, locust tree, oleander, paper mulberries; Perennial plants such as the ground selected tuber of dwarf lilyturf, iris, fringed iris, Lysimachia christinae.One of every earthing is then in time afforested one, to recover forest ecological environment as early as possible.
The refuse landfill of building according to the designing institute of mountain region provided by the invention ecological safety type refuse landfill has following architectural feature: (1) builds barricade in the lower side of landfill yard or around whole landfill yard; (2) the landfill yard end face is the ladder band shape, and the ladder band is made up of alternate table top and inclined-plane, and the gutter that water can be discharged to outside the landfill yard is arranged in the bottom on each inclined-plane; (3) on above-mentioned all or part of inclined-plane table soil, cover watt; Partly plant plant at unlapped table top.
Preferred surface slope is with 25～35 °, and width is no more than 5 meters, and table top is 1-3 meters.
The present invention enters the state that makes rubbish be in relatively dry in the rubbish heap by the natural rainwater of effective minimizing, and refuse landfill does not have water more than needed and exosmoses.Thereby the scope of strict control refuse pollution is confined in the landfill yard, is unlikely to pollute external environment.Behind the rubbish earthing, select the configuration of suitable plant by science, fast quick-recovery or reproduce vegetation forms more stable artificial plant group, refuse landfill is recovered as early as possible or strengthens its Ecosystem Service.
