Description
Technical field
The present invention relates to a kind of soil disinfection and cure purifier, belong to soil remediation field.
Background technology
Modern humans's frequent activity, very serious to the destruction of ecological environment, soil is natural collecting post and the purified treatment place of all kinds of discarded object, when each pollutant of accommodating in soil is too much, affect and exceeded the self-purification capacity of soil, soil is just no longer applicable to planting plants.Cause the reason of soil pollution a lot, as pollutant sedimentation in industrial sludge, agricultural garbage, sewage irrigation, air, a large amount of mineral chemical fertilizer and agricultural chemicals etc. used containing heavy metal.The existing arable land of China is subject to pollution in various degree, and contaminated soil will cause crop production reduction, even likely cause pollutant in agricultural product to exceed standard, and then be detrimental to health.In addition, along with the acceleration of economic development and urbanization, the contaminated sites that industrial and mining enterprises cause is also very serious.Due to change and the adjustment of the industrial structure and city layout, some contaminating enterprises such as chemical industry, metallurgy moves one after another, and add the bankruptcy of some enterprises, contaminated site constantly increases.Soil contamination problem has become the malignant tumor of restriction urban development, becomes Environmental security hidden danger and social concern.Therefore contaminated soil administers the important content having become environmental protection, and wherein contaminated soil remediation administers the important content become in contaminated soil improvement field.
As application number a kind of contaminated soil remediation system adopting recirculating that has been 201510136052.6 disclosure of the invention, first soil enter the inner bag of waste heat cycling kiln through feeding warehouse, enter the inner bag of thermal desorption rotary kiln again, send into through the first conveyer belt again in the interlayer of waste heat cycling kiln, finally exported by the first soil again and discharge; Air enters combustion chambers burn through burner, the flue gas produced enters moving linearly in the interlayer of thermal desorption rotary kiln, for the helical movement in the interlayer of pipeline access waste heat cycling kiln again, finally discharged by the exhanst gas outlet be arranged on waste heat cycling kiln hood again; The waste gas produced in thermal desorption rotary kiln inner bag burns through pipeline access burner, the waste vapour produced in waste heat cycling kiln inner bag accesses condensation separator through pipeline, gas after condensation separator is separated burns through pipeline access burner, and the liquid after condensation separator is separated is discharged through pipeline.The feature such as have efficient energy-saving, low cost of manufacture, easy to implement, repairing effect is good, has wide market prospects.
And for example application number is a kind of soil remediation method of invention of 201210015621.8, comprise the following steps: 1) soil to be repaired is transported to vibratory sieve by one-level conveying worm, sieved soil is transported in Thermal desorption stove rotary kiln through deuterostrophies conveyer and adds Thermal desorption; 2) soil through roasting is delivered to crusher in crushing through three grades of conveying worms; 3) then 280-320 DEG C is cooled to by the first water condenser from Thermal desorption stove rotary kiln waste gas out; 4) waste gas through the first water condenser enters mercury separator again, isolates granule dust and liquid mercury; 5) enter secondary combustion chamber burning from mercury separator waste gas out, then through gas condenser and the second water condenser, make the temperature of waste gas be down to 150-200 DEG C, then through sack cleaner dedusting, the gas after dedusting is arranged outward by air-introduced machine.Soil remediation method of the present invention can solve soil contamination problem preferably, and can directly use through the soil repaired, in addition, renovation technique is simple, and cost is lower.
Above the method for soil sanitation reparation is just processed for the foreign matter in soil, by composition unnecessary in soil to heat resolve, not do not carry out for the acid-base value of soil and salinity adjustments to process, and the acid-base value of soil and salinity are the key factors affecting plant growth, also the pernicious gas distributed after heating is not processed.
