Description
Technical field
The present invention relates to a kind of device for the research of heavy metal-polluted soil resistance control techniques, belong to pollution ecology and repair field.
Background technology
Soil is the important component part of terrestrial ecosystems, is " skin " that covers earth top.Yet along with developing rapidly of industry, a large amount of pollutants enters soil environment by all means, heavy damage soil texture, wherein heavy metal pollution is very serious.The elements such as mercury (Hg), cadmium (Cd), plumbous (Pb), chromium (Cr) and metalloid arsenic (As) have obvious toxic effect to organism, in addition, also having under the constants such as zinc (Zn), copper (Cu), nickel (Ni), tin (Sn), vanadium (V) is crop and human nutrition element, and the excessive metallic element that shows toxicity all belongs to the polluted heavy metals in environmental pollution category.
At present, study more remediation of heavy metal-contaminated soil both at home and abroad and mainly contain physical chemistry technology, biotechnology and agriculture chemistry measure.The shortcomings such as the method for improving the soil and electrochemical process are common physical chemistry recovery techniques, and the method for improving the soil is only applicable to the with serious pollution soil remediation of small size, and exists treatment cost high, and quantities is large, and nonideal heavy-metal contaminated soil governing measure.Electrochemical process is mainly electrode insertion in the soil of water saturation, and passes to low-intensity electric current and make metal ion move enrichment to electrode, thereby reaches the object of removal heavy metal.The method easily causes secondary pollution, and the regulation effect of the sandy soil high to permeability, conductibility is poor is not good.Biological method is mainly to utilize plant to absorb the heavy metal in soil, is taken away, and realizes the improvement to contaminated soil.Phytoremediation mainly comprise plant extraction effect, plant can show effect with and rhizosphere filtration, it is larger that the treatment effect of this method is affected by phytomass, and the improvement cycle is long, cannot meet the requirement that short-term is administered contaminated soil fast, there is certain limitation.
Present stage, research about the removal device of Heavy Metals in Waters makes some progress, paddy field, patent < < pond heavy metal adsorption device > > provides the device (patent No. 201320522968.1) of heavy metal adsorption in a kind of water, but this device there is no the absorption fixation that method is applied to heavy metal in soil.For this reason, be necessary to research and develop novel heavy metal-polluted soil resistance control device, for the reparation of heavy-metal contaminated soil provides new technology and thinking, this is for reducing environmental risk of heavy metal and significant to the harm of population health.
Summary of the invention
The deficiencies such as existing remediation of heavy metal-contaminated soil quantities is large, treatment cost is high in order to overcome, easily cause secondary pollution, the improvement cycle is long, the invention provides a kind of new and effective, simple to operate, transportation easily for the device of heavy metal-polluted soil resistance control techniques research.
The technical solution used in the present invention is:
A kind of device for the research of heavy metal-polluted soil resistance control techniques, comprise with cylindrical tube and the base that can open and close circular top cover, described cylindrical tube is installed on described base, in described circular top cover, be installed with the motor of adjustable speed, in described cylindrical tube, agitator is housed, it is characterized in that: described agitator comprises shaft and is connected in described shaft and along the axial arranged spiral blade of shaft, the motor shaft of described motor and described shaft are in transmission connection; On the sidewall of described cylindrical tube, vertically offer a plurality of sample taps from top to bottom, the lower end of described cylindrical tube offers outlet, can collect pedotheque after treatment by this outlet.
Further, in described circular top cover, be provided with and be convenient to open or the handle of closed circle top cover; Pedotheque and heavy metal adsorption fixedly microballoon can add in described cylindrical tube when top cover is opened.
Further, described sample tap is four, and the sample tap described in four to the distance of described circular top cover is respectively 10,20,30 and 40cm, can realize the collection to different depth pedotheque.
Further, described base below is provided with and is convenient to mobile pulley.
Motor of the present invention is regularly motor of speed change, can be by regulating rotation time and the rotating speed of motor to realize the control to the mixing time of agitator and mixing speed.Regulate mixing time and speed to optimal level, can make contaminated soil and absorption fixedly microballoon fully contact, obtain good heavy metal and hinder and control effect.
When the present invention uses, after first by the soil of heavy metal pollution, fixedly microballoon fully mixes according to the ratio of 0.5～1.2kg microballoon/kg soil (weight in wet base) with the heavy metal adsorption preparing, open described circular top cover, by above-mentioned contaminated soil and heavy metal adsorption fixedly the mixture of microballoon add the inside to cylindrical tube, dosage was not to have whip topping to be as the criterion.After adding, closed circle top cover is also connected motor power, regulates motor speed to 40r/m, after rotation 30min, stops, and under timer effect, after 4 hours, the rotating speed with 40r/m stirs again, and the time of staying is 24～72h.Under the abundant stirring of agitator, heavy metal adsorption fixedly microballoon contacts and fixes with the heavy metal ion in soil.Now, can to pedotheque, gather by four sample taps, the content of beary metal of measuring in soil is weighed treatment effect.
The present invention's profile used is cylindrical tube, can avoid the Dead Core Problems of cuboid or cell body, and soil and adsorption microspheres can not deposited in dead angle, is convenient to the cleaning of heavy metal resistance control device and utilizes once again.
Beneficial effect of the present invention shows: rapidly and efficiently, easy and simple to handle, simple in structure, cheap for manufacturing cost and be convenient to transportation, can be applicable to the research and development of original position soil heavy metal resistance control new technology.
