Description
Technical field
The present invention relates to the impermeable technical field of garbage loading embeading.In particular it relates to a kind of be used for garbage loading embeading
Antiseepage slurry of divider wall and preparation method thereof.
Background technology
With the developing rapidly of China's economy, the quickening of industrialization and urbanization process, living standards of the people improve constantly,
Also cause Municipal Domestic Garbage Output to sharply increase simultaneously, detrimental effect is brought to environment.At present to the processing side of rubbish
Formula mainly includes burning, landfill and compost, but main by the way of landfill.Even if early stage, processing rubbish was using burning or heap
The otherwise processeds such as fertilizer, last residue are also required to be handled by way of landfill.
Industry can produce certain negative effect it is believed that handling rubbish by land-fill method to environment, increase environment
Load.Therefore, when being filled to rubbish, in order to prevent poisonous, noxious pollutant contaminated soil in garbage leachate and
Underground water source is, it is necessary to which rubbish is isolated with surrounding formation.Simplest quarantine measures are set in refuse landfill surrounding and bottom
Put antiseepage permeable system, such as bed course of impermeable wall, barrier film and refuse landfill bottom etc..The impermeable system of refuse landfill
On the one hand the validity of system depends on whether antiseepage permeable system effectively can prevent Leachate site from permeating, i.e., whether have relatively low infiltration
Coefficient.On the other hand, can the validity of refuse landfill antiseepage permeable system depends on antiseepage permeable system effectively prevent percolate
Whether whether middle pollutant is to external migration, and can simultaneously effective prevent interflow subsurface drainage from entering refuse landfill, i.e., to diafiltration
Liquid has good absorption retardation.
Chinese invention patent application 201410156248.7 discloses a kind of refuse landfill anti-seepage slurry material and its preparation side
Method, it is bentonite that the anti-seepage slurry material is organised by polyvinyl alcohol, Portland cement, flyash, polycarboxylate water-reducer, pure
Alkali etc. is made.Because needing to use soda ash in the technique as slurry material dispersant, load easily is caused to environment.
