Description
Technical field
The present invention relates to contaminated soil remediation technical fields, more particularly to a kind of life for restoration of soil polluted by heavy metal
The method of object charcoal base manure, preparation method and rehabilitating soil.
Background technology
With the continuous quickening of industrial or agricultural fast development and city process, emitted from industrial or agricultural and daily life
Heavy metal is continuously increased, The Heavy Metal Contaminated Soil also getting worse.Soil is human survival and the important natural resources of development
One of rely existing basis with entire terrestrial ecosystems, and be important environmental element.Heavy metal in soil passes through migration
And conversion, not only harm the crops growth, while endangering animal and the health of the mankind.According to the Ministry of Agriculture of China count, China by
Heavy metal pollution especially Cd contaminated lands account for about the 1/5 of total area under cultivation, every year due to heavy metal pollution caused by grain
More than 20,000,000 tons, the economic loss thereby resulted in reaches 20,000,000,000 yuan for loss.Therefore, China's heavy metal pollution of soil is asked at present
Topic has seriously threatened the safety in production of our agricultural product, needs to repair contaminated soil.
Investigation according to Chinese Ministry of Environmental Protection 2005 to about 6,300,000 square kilometres of China's national territorial area, Farmland contamination exceeding standard rate are
19.4%, about 3.5 hundred million mu of exceeded area.Pollution is in exacerbation development trend, in nearest 20 years, weight in topsoil
Metal Cd increases 82.4% in southwest, and coastal area increases 69.0%, and North China, northeast, the Northwest increase
10% -40%.Since 2002-2012,21 provinces of the Ministry of Agriculture pair (city of area) rice, wheat, corn and soybean, vegetables etc.
The investigation of place of production part soil, in total 4382.44 ten thousand mu of investigation, exceeded area is 446.79 ten thousand mu, exceeding standard rate 10.2%.
As it can be seen that agricultural products in China Producing Area Soil heavy metal pollution is serious.
In-situ immobilization is a kind of very effective method as heavy metal pollution of soil Treatment process, and by people
Most attention, be particularly suitable for repairing in large area, the agricultural land soil of slight heavy metals exceeding standard, realize heavy metal pollution arable land
While production while repair.Apply a kind of more economical original position that heavy metal absorbent is restoration of soil polluted by heavy metal into soil
Processing method.Soil application heavy metal repair materials, by changing the chemical shape of soil pH value and heavy metal element in the soil
State and occurrence status increase absorption point and promote the co-precipitation of heavy metal ion and the other components of soil (including repair materials)
Etc. processes, so that heavy metal-polluted soil biologically effective state is converted into the not available form of biology, to inhibit heavy metal in the soil
Migration and biological effectiveness, reduce heavy metal contaminants to the toxicity of environmental organism, reach restoration of soil polluted by heavy metal
Purpose.
In recent years, researcher screens or has developed large quantities of repair materials for heavy metal pollution absorption, a side
Face provides technical support and product guarantee for arable land heavy metal pollution repairing and treating;On the other hand, material is repaired using heavy metal
Manually or mechanically operation increases the input of agriculture production cost for material and repair materials, since effect is compared in agricultural production itself
Benefit is low, and the heavy metal repair materials using single effect are difficult that peasant is mobilized actively to join in arable land heavy metal pollution repairing and treating
, expensive cost can not also be promoted and applied on a large scale, agricultural product quality and safety caused by heavy metal pollution of ploughing
It is not effectively controlled, and has the tendency that further deteriorating.From the point of view of agricultural production practice, best soil is repaiied
Recovering technology is the ecological functions that can either keep soil, does not destroy the fertility for even providing soil, and can effectively hinder a control huge sum of money
The pollutants such as category enter food chain.Therefore, a kind of repair materials integrating absorption heavy metal and agricultural production are researched and developed, simultaneously
Heavy metal absorbent and crop nutrient are provided, heavy metal repair materials are blended in the fertilising of agricultural production, is really anticipated
Realize that heavy metal pollution arable land is repaired in production in justice.
Charcoal refers to biomass resource (crop material, woods fruit tree branch, the animal wastes being widely present with nature
Deng) based on, pass through the carbonaceous material of thermal cracking generation under anoxic conditions.The phosphorus content of charcoal is 40%-75%, and
Also a small amount of minerals and volatile organic compounds, charcoal are not easy to be decomposed by environmental microorganism in alkalinity.In addition,
Charcoal is porous mass, and there is extremely abundant gap structure and huge specific surface area, these characteristics to impart charcoal
With powerful absorption property, therefore charcoal has stronger cation exchange property (big cation exchange capacity (CEC)), therefore, raw
Object charcoal can adsorb the heavy metal element in soil, can effectively slow down heavy metal pollution of soil.
However the effect of these processing methods in the prior art and unstable, not safe enough, and cost is big, treatment effeciency
It is low.
