Abstract
The invention belongs to the technical field of remediation of soil polluted by heavy metals. The mixture of plant remains in the nature is processed into ultrafine powder with a size less than 10 micrometers by a multistage controllable track-changing ball milling technology. The obtained ultrafine powder comprises a large amount of organic high-molecular functional groups with a high activity, so the ultrafine powder can carry out complexation, chelation, and combination effects with heavy metals in the soil to reduce the activity of heavy metals in the soil, and the heavy metal absorption of plants is inhibited. The provided deactivator has the advantages of simple operation, low cost, and rapid effect, and thus has a wide prospect in the field of remediation of soil polluted by heavy metals.
Description
Technical field
The technology of the present invention belongs to heavy metal pollution of soil recovery technique field, is specifically related to a kind of plant remains mixture micro mist for soil remediation and the technology improving plant-growth.
Background technology
Heavy metal pollution of soil problem mainly contains two large classes, and 1, the exploitation in mine and smelting, the water and soil heavy metal contamination caused, 2, the soil acidification that causes of chemical fertilizer a large amount of uses for years and heavy metal contamination.Duo Diduo provinces and cities, the especially Yangtze valley and areas to the south, crop heavy metals exceeding standard problem is more and more serious, so that defines serious social concern.At present, large-area heavy metal pollution of soil rehabilitation cost is high, and effect is low, lacks effective governing measure, and China's ecotope is asked day by day serious, is badly in need of a kind of cost low, effective treatment technology.
The technology of the present invention utilizes cryodrying pre-treatment to make plant remains moisture content reach 4-15%, fine grinding is worked into particle diameter less than 10 microns, there is extremely strong activity, organic matter is made up of multiple polymer functional group, the soil heavy metal ion generation chemical combination of energy fast and under sour environment, complex reaction, make heavy metal can not participate in exchange of substance between root system of plant and soil with ionic condition, solve heavy metal-polluted soil excessive problem in some sense.Through this application experiment in several years, plant remains micro mist soil heavy metal passivant result of use is obvious, and cost is low, and using method is simple.While heavy metal-passivated, improve soil acidification problem, also supplement soil nutrient elements, improve soil quality, crop quality and output can also be made to be improved.
Summary of the invention
The feature of this plant remains micro mist soil heavy metal passivant, comprises following integral part:
1, be contained in brown coal, peat, the peat composed of rotten mosses containing the natural phant remains of organic more than 60%, through the micro mist of multistage controlled change rail ball milling retrofit to particle diameter less than 10 microns, the heavy metal passivation in soil can be made, suppress plant absorption heavy metal.
2, mix with solid alkali through the micro mist of multistage controlled change rail ball milling retrofit to particle diameter less than 10 microns containing the natural phant remains of organic more than 60%, change soil acidification condition, heavy metal-passivated, suppress plant absorption heavy metal.
3, mix with mineral substance through the micro mist of multistage controlled change rail ball milling retrofit to particle diameter less than 10 microns containing the natural phant remains of organic more than 60%, the heavy metal passivation in soil can be made, suppress plant absorption heavy metal.
4, water content must be made to be 3-15% through pre-treatment containing the natural phant remains of organic more than 60%.
5, plant remains micro mist soil heavy metal passivant organic content is greater than 55%.
The essential characteristic of the technology of the present invention is:
One, the plant remains that occurring in nature is natural through impacting, being crushed to particle diameter less than 10 microns, make organic polymer functional group fully expose at normal temperatures and pressures, active raising;
Two, under sour environment, plant remains micro mist can with soil heavy metal ion generation complexing, combination reaction, make heavy metal not participate in the exchange of substance between root system of plant and soil with ionic state;
Three, plant remains micro mist can be composite with alkali, can be used for improving soil acidification, suppresses plant absorption heavy metal;
Four, the organism contained by plant remains micro mist and trace element can play significant catalysis and medium effect to the breeding of microorganism;
Five, plant remains micro mist can directly be incorporated in soil, also water soluble pouring, simple to operate;
Six, plant remains micro mist soil heavy metal passivant organic content is greater than 65%.
Example one
Guangxi, the heavy metal contamination that mine development causes, soil Cd exceeds standard 23 times.1.5 mu of 90 strain mulberry tree, the peat soil of organic content 71%, adds 5%NaOH and 3%KOH, is worked into more than 2000 orders, the water of the molten water 300kg of 3kg, with atomizers spray blade face, branch, trunk and root, every 5 days 1 time, totally four times, total consumption 12kg.Mulberry leaf are up to standard.P in soil H value is adjusted to 6.6 by 3.9.
Example two
Zhuzhou,hunan, 10 mu, acidified water rice field, use the peat soil of organic content 75%, add 5%NaOH and 5%KOH, be worked into more than 2000 orders, the water of the molten water 5000kg of 50kg, water before ploughing to spill to water after once ploughing in ground and spill ground once, within after rice transplanting 5 days, to pour in paddy field once, within 30 days, spray spike of rice once afterwards, totally four times, total consumption 200kg.Rice cadmium content 0.043ppm, the paddy rice of contrast ordinary method plantation, rice cadmium content is 0.457ppm, is reduced to 1/10th.
Example three
Shouguang, Shandong green house of vegetables, 553 square meters, use the peat soil plantation balsam pear of organic content 75%, balsam pear heavy metal content is respectively: 1, arsenic 0.027, and 2, mercury (not detecting), 3, plumbous 0.0092,4, cadmium do not detect, 5, chromium do not detect.Contrast uses chicken manure: 1, arsenic 0.068, and 2, mercury (not detecting), 3, plumbous 0.092,4, cadmium do not detect, 5, chromium 0.025.Heavy Metals Quantity of Crop in Wastewater significantly reduces.
