Form is the plastic materials such as solid semisolid, then select scraper plate belt pulley conveyer belt 14 to carry out the Output transfer of material, output
After process, material is shifted using engineering equipment;If after processing material due to moisture content it is higher, its final form is for fluidised form
During non-plastic material, then select fluid materials conveyor module be fluid materials keep in struggle against 23 and Pulp pump 24 carry out the output of material
Transfer.
Embodiment 1:
Central-South certain certain chromium salt production factory for saving leaves one piece of pollution of chromium place after moving, and the soil in place exists serious
Cr VI Cr6+With total pollution of chromium, through a series of prospecting investigation and laboratory lab scale demonstration, the part soil in the plot is needed
Dystopy electronation and the treatment technology of dystopy stabilisation solidification is used to be processed.Before whole audience repairing construction is started,
Need to carry out the pilot scale checking of certain scale.In the project, the present invention using as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5
Module is combined, the contaminated soil of implement scale of marching into the arena according to dystopy electronation and dystopy stabilisation two sets of techniques of solidification
Process.The contaminated soil indices that production process is selected are as shown in table 1 below:
Certain chromium salt production factory contaminated site sample pollution of chromium data of Central-South certain province of table 1
Pollution key element |
Hexavalent chromium concentration Cr6+ |
Total chromium concn Cr |
Content mg/kg |
973 |
12900 |
Instruction according to pilot run adds corresponding electronation medicament, carries out dystopy reduction treatment, process
Purpose is the hexavalent chromium polluted key element eliminated in former contaminated soil as much as possible.In the scale up test, the present invention is combined
After corresponding liquid preparation is processed to contaminated soil, Cr VI Cr6+Concentration minimum be down under 2.7mg/kg, and the effect
Chemical feeding quantity compared with pilot plant test result, incrementss be less than 15%, the result embody the present invention for dystopy electronation
In technique, the utilization rate of chemical agent is higher.
According to the instruction addition stabilisation solidification medicament of pilot run, dystopy stabilisation cured is carried out, is processed
Purpose be as far as possible reduce contaminated soil in Cr VI and total chromium animal migration, make the soil after reparation use HJ/T
When 299-2007 solid waste Leaching leaching methods carry out extraction analysis, the Cr VI Cr in soil6+To the greatest extent may be used with chromium
Few can be detected.In the scale up test, the present invention combines corresponding solid stabilizing solidification medicament and liquid stabilisingization is solid
Chemical medicine agent is processed to contaminated soil, and after process, soil is conserving standard method two days later according to HJ/T 299-2007
Leaching analysis is carried out, Cr VI Cr in final lixiviating solution6+With the minimum leaching concentration of total chromium be respectively 0.12mg/L and
0.45mg/L, compared with corresponding pilot run, medicament has no increase to the result under the effect, and the result has fully demonstrated this
It is bright in the dystopy stabilisation curing process for carrying out soil, the completeness of technological effect is good.
In this pilot scale project, equipment is directly located on the ground of place relatively flat, and installation and debugging take half a day altogether,
Check through the scale up test to 35 tons of contaminated soils, treatment effect reaches production engineering specifications, processing speed reach 8-10 tons/
Hour.
