Abstract
The invention relates to environment-friendly treating technology and application of waste sludge, in particular to a solidifying method for sludge, which includes adding 5%-15% weight percentage of cement in sludge and stirring, mixing and solidifying. After solidifying treatment, sludge is applied to cultivation of plants serving as cultivating soil. The solidifying method for the sludge and the application of the sludge for cultivating plants serving as cultivating soil solve problems that the existing sludge solidifying technology is low in induration strength and hard in sludge dehydration and external added materials are large in specific gravity, enable solidified sludge to cultivate plants serving as cultivating soil, and effectively recycle sludge.
Description
Technical field
The present invention relates to a kind of environment-friendly treating process and application to waste silt.
Background technology
Along with the acceleration day by day of urban modernization pace of construction, all produce ten hundreds of building wastes and domestic refuse every day thereupon.People recognize gradually environment to self the life importance the time, the disposal of these building wastes and domestic refuse more and more causes people's attention.
Though also research and development are energetically handled and utilized to the method that has mud to utilize cement to be cured at present to the disposal after solidifying.
Summary of the invention
The purpose of this invention is to provide a kind of curing of mud and as the application of planting soil plantation plant; The concretion body strength that has solved the existence of existing sludge solidification technology is low; The sludge dewatering difficulty; The heavy shortcoming of external admixture material, and making behind the sludge solidification as planting soil plantation plant, effectively regenerated using the value of mud.
Concrete technical scheme of the present invention is:
A kind of curing of mud adds the cement of 5% ~ 15% weight percent in mud, mix curing.
Further, after the solidification treatment of above-mentioned mud as the application of planting soil plantation plant.
Further, above-mentioned cement is silicate cement.
Technique effect of the present invention:
Adopt the curing of of the present invention kind of mud, only need short 10 day time to reach the effect of 2 years of the common stacking processing of present mud.In addition, the application as planting soil plantation plant not only greatly reduces the cost on time and economic benefit, more reasonably uses but also reach resource.
Specific embodiments
Data below in conjunction with after the test describe in further detail the present invention:
In the mud of common 25% water ratio, adding additive is conch board Portland blast 42.5R, adds the additive of 5.1%, 10.20% and 15.30% weight percent respectively, constitutes three groups of sample A, B and C group.It is following to leave standstill nature normal temperature indoor one all backs test data:
Almost nil for the mud experiment water cut after 10 days that dewaters, however for the mud of placing naturally sunlight be exposed to the sun down with the inadequate prerequisite of rainfall under need placement reach 2 years and could carry out later use such as landfill to it.This shows the obvious processing effect of anhydrating for mud.No matter be time cost or this processing method obvious economic of stacking land use cost.
Further, above-mentioned three groups of mud of handling well are carried out the environmental and ecological experiment of planting vegetable: do following experiment through natural drying in the sun mud, working sample A, B and CPH value are respectively:
A,PH=7~8 B,PH=8 C,PH=8
Observe from the weight of PH test paper color and to draw three sample standard deviations of pH value and present weakly alkaline.
Further, three groups of samples are done two groups of experiments respectively, for mixing and stirring pearlstone and not mixing and stirring the dried mud planting vegetable vegetable seed of pearlstone.
Account for 2.5% of mud quality for what mix and stir pearlstone.
The first average daily place, indoor cool place of placing, 20 ℃ of room temperatures are watered and are seeped water until ground moistening.
Observe its growing state: rear section vegetables vegetable seed all had germination on 2nd.
The healthy and strong dish seedling that grows up to of vegetables vegetable seed after one week.
The plantation of good water-permeable and air permeable sexual compatibility plant is arranged from result's solidified mud.
Claims (3)
1. the curing of a mud adds the cement of 5% ~ 15% weight percent in mud, mix curing.
2. the curing of mud according to claim 1 is characterized in that, said cement is silicate cement.
One kind according to claim 1 after the solidification treatment of mud as the application of planting soil plantation plant.
