Description
Technical field
The utility model belongs to soil remediation field, and what be specifically related to is a kind of heavy-metal contaminated soil treating apparatus.
Background technology
Heavy metal pollution has become one of maximum soil pollution of human life's health formation harm.Heavy metal not easily moves in soil, is not easily degraded by microorganisms, and the holdup time is long, crop production reduction and agricultural product quality can be caused to decline, and then be detrimental to health.
Original position elution technique is by leacheate perfusion in contaminated soil, and reclaim the heavy metal in ring waste, this technical costs is lower, and technique is simple, but remediation efficiency is low, easy polluted underground water.
Patent No. CN203635613U discloses a kind of heavy-metal contaminated soil dystopy drip washing equipment, propose dystopy elution technique, this equipment has lacked the pretreatment in soil early stage, soil fully can not be reacted with medicament, soil is not repaired completely, secondary pollution risk is comparatively large, improves production cost.
Summary of the invention
The purpose of this utility model is the above problem overcoming prior art existence, provides a kind of heavy-metal contaminated soil treating apparatus, by treatment system in early stage, effectively sieves soil, soil can fully be contacted with treatment agent.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of heavy-metal contaminated soil treating apparatus, comprise conveying worm, soil is delivered to primary dcreening operation seperator by belt by described conveying worm, described primary dcreening operation seperator connects dusting cover seperator by belt, described dusting cover seperator connects drip washing pond, described drip washing pond is by pipeline coupled reaction pond, and described reaction tank connects treatment tank.
The sieve mesh of described primary dcreening operation seperator screen cloth is 40-50 order.
The sieve mesh of described dusting cover seperator is 70-100 order.
Leacheate in described drip washing pond is clear water or hydrochloric acid, and described drip washing pond adopts pvc pipe to build.
Calcium hydroxide is provided with in described reaction tank.
PH adjusting agent is provided with in described treatment tank.
The beneficial effects of the utility model are:
The utility model is novel in design, structure is simple, by effectively carrying out primary dcreening operation and dusting cover to soil to soil pretreatment system, improve the contact pairs effect of soil and medicament in drip washing pond, drip washing pond adopts PVC board to build, simple and convenient, portable cost-saving again, throw in wastewater disposal basin and have pH adjusting agent, make solution recover neutral, not easily produce corrosion.
