Description
Technical field
The present invention relates to soil treatment equipment technical field, specifically, relate to a kind for the treatment of apparatus of yellow phosphorus contaminated soil.
Background technology
Yellow phosphorus is a kind of toxic articles, and the toxic dose of people is 15mg, and lethal dose is 50mg, particularly serious to the toxicity of fish.Yellow phosphorus is a kind of highly stable chemical substance, if be soaked in water or bury in underground, even if experience decades even go up a century all can not natural degradation.When yellow phosphorus runs into air, can be oxidized lentamente, just spontaneous combustion can occur when environment temperature is more than 40 degree, produce a large amount of toxic smogs.
Phosphorus mud, is again mud phosphorus, is the accessory substance produced in producing yellow Phosphorus by electric oven process.It is reported, use electric furnace process often to produce 1 ton of yellow phosphorus, 0.1t ~ 0.35t phosphorus mud will be produced.Phosphorus mud is primarily of yellow phosphorus, solid impurity and water composition, and wherein the content of yellow phosphorus is 10% ~ 90%.Before last century the nineties, because the environmental consciousness of people is thinner, add that treatment technology is at that time relatively backward, a lot of phosphorus production producer is poured into the phosphorus mud produced in production process in the pond near factory or is imbedded in underground.In addition, also there is the problem of the row's of stealing Yellow Phosphorus Wastewater in early stage phosphorus production producer, causes factory's Soil Surrounding to be polluted by yellow phosphorus in process of production.
Along with the development of Process of Urbanization Construction, some relating to phosphorus production or using producer progressively to move near urban district, when these plot of exploitation, encounter the phosphorus mud and yellow phosphorus contaminated soil that are imbedded in underground.Although the domestic and international recycling technology for phosphorus mud and device have a variety of at present, such as, a kind of equipment reclaiming yellow phosphorus in phosphorus mud for continuous evaporation provided in China Patent No. " 201420054043.3 ", and the device etc. of yellow phosphorus is extracted in a kind of phosphorus mud decompression distillation provided in China Patent No. " 201320021334.8 ".But the disposal ability of existing phosphorus mud treatment facility is all lower, the residue after recycling still containing a certain amount of yellow phosphorus, and is only suitable for the recycling for the higher phosphorus mud of yellow phosphorus content.Yellow phosphorus content due to yellow phosphorus contaminated soil is general lower, pollute earth volume larger again, reparation requires high, and therefore existing phosphorus mud recycling and processing device also exists many inadaptabilities, and how effectively processing yellow phosphorus contaminated soil has become one of difficult point of soil remediation industry.
