Description
Technical field
The present invention relates to garbage treating process, more particularly, to refuse landfill concentrate recycling treatment and rubbish waterproof
Cover in-situ applications technique.
Background technology
The municipal refuse that China is more than 80% is handled by sanitary landfill method.Sanitary landfills, which is most economical, meets environmental protection wants
The method for the municipal house refuse of processing asked, but one major defect is to will produce landfill leachate.Due to generally adopting at this stage
It is limited that loess covers rainwater-proof function, garbage filter output of fluid abruptly increase when rainy season.As shown in Figure 1, currently, most landfill yards
Using reverse osmosis membrane processing landfill leachate, but the landfill leachate through technique go out after still generate at the concentrate of 20%-30%
It sets, and disposes that the partial concentration liquid process costs are very high, and the relevant technologies are urgently researched and developed.Therefore, most of refuse landfills are directed to
The method of disposal of concentrate is in recharge to garbage filter liquid pool or junk-heap body.On the one hand Concentrated liquid recharge increases subsequent film
The pressure of processing simultaneously increases follow-up operation cost；On the other hand, concentration is returned in diafiltration liquid pool, harmful substance therein
Do not disposed at all.Although the techniques such as burning, multiple-effect evaporation can be from basic disposition pollutant, its construction cost and fortune
Row cost is excessively high, and the sludge, the lime-ash that generate recycle difficulty larger, the best side of the not following landfill leachate concentration liquid
Method.Therefore, the R＆D direction of landfill leachate concentration liquid disposal technology should cure to harmful substance and recycling turns
It moves.
Since the most of sanitary garbage landfill yards in China do not take effective operation area rain-proof to cover, most of rainfalls will ooze
Enter landfill operation area and form Leachate site, therefore its Leachate site generates bigger compared with developed countries；Separately due to something lost such as policy, funds
It has been more than environmental risk warning line to stay questions and prospect, part Landfill volume of cargo in storage.The recharge of concentrate also additionally increases
The yield of percolate.Therefore, as can solving the waterproof covering problem of refuse landfill, and a kind of concentrate recycling profit is researched and developed
With technology, then it comparatively fast can faster reduce percolate storage and new percolate generates, reduce and alleviate the ring that garbage leachate causes
Border risk, while reducing cost of disposal.
Invention content
The object of the present invention is to provide a kind of refuse landfill concentrate recycling treatments and rubbish waterproof covering original position to answer
With technique, the technique using garbage percolation concentrated liquor as solvent, can disposal of resources garbage percolation concentrated liquor, and to generating
The landfill yard operating area of Leachate site carries out covering in situ.
Of the existing technology in order to solve the problems, such as, the technical solution adopted by the present invention is as follows：
Refuse landfill concentrate recycling treatment and rubbish waterproof cover in-situ applications technique, include the following steps：
1. by being mixed in solidification base-material input siccative hybrid system, is mixed 4-30 minutes under normal temperature and pressure, form solidification base
Expect mixture；
2. the concentrate that Leachate site is generated after the disposition of biochemical and membrane filtration process is put into jointly with solidification base-material mixture
It is stirred evenly in mixing and stirring system, is stirred 5-30 minutes under normal temperature and pressure, form uniform mixture；
3. curing agent is added in uniform mixture, high viscosity pasty composite material is formed；It will uniformly be mixed using spraying equipment
Material is uniformly injected in refuse landfill operation area surface, directly carries out covering in situ to refuse landfill.
The solidification base-material is made of posi-shell and cement or flyash, posi-shell and cement or powder
The weight part ratio of coal ash is 1：2-1：2.5.
The weight part ratio of the solidification base-material and concentrate is 1:1.5-1:3.0.
The curing agent is by quick lime, one or both of sodium bentonite and diatomite and biphosphate
One or both of calcium and sodium dihydrogen phosphate are 10 according to weight part ratio：10：1 composition, the curing agent with uniformly
The weight part ratio of mixture is 1：100-1：150.
The siccative hybrid system is siccative blender.
Siccative the blender 20 turns/min, 50m3。
The mixing and stirring system is JS500 concrete mixers.
The spraying equipment is hydraulic jet equipment, and covering speed of application is 25m2/ minute, construction area 2000m2/
It, constructs 480 minutes daily.
Advantage for present invention is with advantageous effect：
After garbage leachate is formed, after being disposed using nanofiltration or the membrane filtration process such as reverse osmosis, small part Leachate site is not
Concentrate is generated by filter membrane, the present invention is to carry out recycling application by solvent of concentrate, by concentrate mixture and admittedly
Agent puts into progress mixing stirring in mixing and stirring system jointly, and curing agent can be organic by the heavy metal in concentrate, macromolecular
Etc. harmful substances be fixed in material and form novel high viscosity pastes；The new material generated after mixing is existed using spraying equipment
Sanitary filling field operation area surface directly carries out covering in situ, formed after dry with rain-proof, fire prevention, every flavour deodorization functions it is hard
Film penetrates into obstruct most rainwater, reduces garbage leachate and generates.50- can be covered after one ton of concentrate joint disposal
150m2.This technique can not only carry out recycling in situ to the Leachate site and concentrate that Sanitary Landfill generates,
The covering that can also construct at a high speed forms dura mater in flakes and is attached to rubbish surface, prevents rubbish from floating with the wind, after tested its waterproof
Performance is IPX3（Rain-proof type）.Its drying and forming-film time is 2-24 hours.The dura mater has automatic degradation function, degradation time long
It is short to be adjusted by increasing and decreasing the ratio of lasting agent, generally -4 years 10 days.The dura mater can substitute loess, for life rubbish
The junk-heap body of rubbish landfill yard field without soil cover, present invention process can also mechanical injection for loess covering after soil layer surface,
Form the waterproof coating above soil layer.The present invention has good environment friendly and higher cost performance.By work of the present invention
Skill is applied to household refuse landfill sites, can effectively solve the handling problems of the garbage percolation concentrated liquor of household refuse landfill sites,
The pollutants curing degree such as most of heavy metals, harmful organic substance is up to 99% or more；The rainwater that 95% or more can be obstructed penetrates into life
Garbage loading embeading operation area forms rain and oozes shunting；90% or more foul gas can be obstructed；It can save at the concentrate of more than half
It sets and covers cost with waterproof, there is good Social benefit and economic benefit.The present invention can by concentrate heavy metal, big point
The son harmful substances such as organic are fixed in fixative, concentrate handling problems are solved from the angle of recycling, at recharge
It sets more thoroughly.The present invention is disposed using soverlay technique in situ without transporting outward concentrate, and the ambient wind in transportational process is reduced
Danger.Present invention process primary construction is invested and operating cost is far below the investment of the techniques such as burning, multiple-effect evaporation.Using this hair
Bright patent can realize that rain sewage diversion function, high degree reduce Leachate site concentrate and generate behind landfill area all covering.
