Abstract
The invention provides a kind of covering method for environmental protection, it utilizes decomposable natural fiber material and natural mineral matter sticker to add that the aqueous solution is deployed into, take off knot property slurries for having the fiber interweaving pasty state, and can utilize the high pressure spraying machine that it is sprayed on the covering, and form only a kind of cladding process of 0.5～1.5 centimeter thick hard film shell, it can suppress distributing of stink in the covering, reaches the function of deodorization; Can stop covering by the rainwater erosion, reduce sewage and produce; Can prevent that covering from dispelling with the wind; Can prevent the effect of flame combustion and improvement sight.
Description
The invention provides a kind of covering method that is used for discarded object, this method is specially adapted to the covering of keeping a public place clean to the rubbish the like waste.
Flourish along with industry, every day institute's emission treatment discarded object, for example also increase thereupon of industry and house refuse.For the rubbish that keeps environmental sanitation, discharging must cover with the soil of certain thickness (15～30 public parts).Yet this method is handled discarded object and is needed a large amount of soils, and not only workload is big, occupy the space, and rubbish is difficult for reaching covering fully, particularly through the wind and rain erosion, soil cover easily goes to pot, and still can't thoroughly solve the environmental protection problem in soot.
The purpose of this invention is to provide the covering method of things such as a kind of discarded object that is used for, particularly rubbish, utilize this method, can reduce workload, utilize discharging space, place (increasing a discharging operating period) fully, can cover discarded object effectively again, keep environmental sanitation.
Covering method for environmental protection provided by the invention, be to utilize decomposability natural mineral matter bonding agent, for example bentonite, clay or contain mineral mixture and natural fiber matter such as magnesium, potassium or calcium, for example the string mixing and water adding is deployed into a kind of fiber interweaving pasty state cementing properties slurries that have, with its sprinkling or spread upon on the covering and to form 0.5～1.5 centimeter thickness coating of one deck, finish covering then to discarded object.Above-mentioned natural fiber matter addition is 1～30% of a bonding agent weight, and natural fiber matter cuts into 0.1～2.5 centimeter long and short fiber.The pasty state cementing properties slurries that are deployed into can be modulated according to the difference that covers processing method.For example adopting mechanical high pressure spraying machine to spray slurries, adjustable to make flowability big slightly, manually smears and adopt, and the flowability of its slurries can be slightly little, so that construction.Utilize method of the present invention on rubbish (or other discarded object) heap, to add pasty state cementing properties slurries, treat that cover layer forms a hard film shell in the back, can suppress distributing of stink in the covering, reach the function of deodorization; And, guarantee clean environment because this film shell is difficult for being played the effect of covering effectively by the wind and rain erosion.Simultaneously,, can heavily cover again and cover again after piling up discarded object, can effectively utilize the space of discharging, improve result of use because cover layer is very thin.Give explanation further in advance below by example to method of the present invention.
Example 1 covering method for environmental protection is handled discarded object
In clay, add the short fiber of plant that cuts into 0.5～1.5 centimeter long fragmentation by 10% weight ratio, be placed on and add 300% water in the agitator, stirring is modulated into pasty state cementing properties slurries, with the high pressure spraying machine above-mentioned slurries are sprayed on the discharging rubbish of piling up, its coverage is 0.6～1 centimeter, these pasty state slurries have fiber interweaving shape tissue, 2～4 hours thin and hard seal coats of the one deck that can become dry and form after spraying, and the sealing that rubbish is tight is well.Accompanying drawing 1 is a kind of heavy schematic diagram of piling up rubbish and overwrite procedure that covers.Wherein 20 is seal coat; 21 is waste layer; 22 for stacking the field.Accompanying drawing 2 is employed high pressure spraying machine schematic diagram, 10 is sprinkler among the figure, can form by a high-pressure pump and conveyance conduit, 11 is the spraying machine feeding port, bonding agent, cellulosic and water are sent in the spraying machine agitator tank by feeding port 11,12 is the mixer in the agitator tank, and said mixture is stirred into uniform pasty state slurries.Slurries are finished covering by the sprinkling construction that high-pressure pump can carry out discarded object.
By covering method provided by the invention, can replace the thick soil horizon cladding process of traditional use, reduce heavy operation, and can fully effectively utilize the space, improve the utilization rate of stacking the field, coverage effect is good simultaneously, can reduce pollution effectively, guarantees clean environment.
Claims (3)
