Description
Technical field
The present invention relates to soil conditioner field, more particularly, to a kind of heavy metal contaminated soil conditioner and its preparation side
Method.
Technical background
Heavy metal pollution of soil（heavy metal pollution of the soil）Refer to due to mankind's activity, soil
The content of minor metallic element in the soil in earth exceedes background value, and too high levels caused by excess deposition, are referred to as soil
Earth heavy metal pollution.Heavy metal-polluted soil refers to, since metal is added in soil by mankind's activity, cause heavy metal in soil bright
The aobvious phenomenon for being higher than primary content and cause eco-environmental quality to deteriorate.Heavy metal refers to the gold that proportion is equal to or more than 5.0
Belong to, such as Fe, Mn, Zn, Cd, Hg, Ni, Co；As is a kind of metalloid, but due to its chemical property and environmental behaviour and heavy metal
There is similarity more, therefore arsenic is frequently included when discussing heavy metal, some is then directly included into the range of heavy metal.Due to
Iron and manganese content are higher in soil, thus are generally acknowledged that they are not soil pollution elements, but under strong reducing condition, iron and manganese
Caused murder by poisoning also causes enough attention.Heavy metal pollution of soil source mainly has：The efflorescence of soil parent material is to soil
The influence of earth heavy metal background concentration, the natural physics of wind-force and waterpower carrying and chemical transfer process, different industrial and mining enterprises work
Industry produces the additional input to heavy metal-polluted soil, heavy metal-polluted soil input and communications and transportation pair under the influence of Agricultural Activities
Heavy metal pollution of soil is passed to.
On there is many methods to the improving technology of heavy-metal contaminated soil, the prior art is as authorized public platform
The Chinese invention patent of 101724404 B of CN, discloses a kind of heavy metal contaminated soil conditioner and plant and chemistry joins
Restorative procedure is closed, the heavy metal contaminated soil conditioner in the inventive method is red mud and the mixture of white lime, utilizes plant
With chemical combined repairing method, pH adjustings are carried out to soil by chemical method, by planting energy crop and hyperaccumulative plant etc.
Heavy metal-polluted soil absorption etc. is carried out, so as to play improvement soil characteristic, gradually reduce heavy metal content in soil, and is finally reached and repaiies
The purpose of earth backing earth, improves the efficiency of phytoremediation, is conducive to large-scale commercial application.But the inventive method only makes
Heavy-metal contaminated soil is improved with the mixture of red mud and white lime, its improved effect is slower, and utilizes plant pair
It is not a kind of method effected a permanent cure that heavy metal in soil, which is adsorbed, therefore is unworthy advocating.
The content of the invention
It is an object of the invention to provide a kind of heavy metal contaminated soil conditioner and preparation method thereof, this heavy metal pollution
Soil conditioner preparation method is simple and practicable, and manufacture cost is relatively low, and to the heavy metal ion adsorbed degradation capability in soil
It is stronger.
Microorganism and its bought enterprise used are in the method for the present invention：Bacillus subtilis, the preferably grand animal in Cangzhou protect
Jian Pin Co., Ltds；Nitrogen-fixing bacteria, Shanxi Phelps Science and Technology Ltd.；Acetic acid bacteria, Jining Yu Yuan bio tech ltd；
Lactobacillus paracasei, Lactobacillus salivarius, Shaanxi Sen Fu natural products Co., Ltd；Bacillus licheniformis, the green section's biology skill in Jiangsu
Art Co., Ltd.
The present invention is directed to the problem of being mentioned in background technology, and the technical solution taken is：A kind of heavy-metal contaminated soil changes
Good dose, it is formed and its parts by weight are：30-50 parts of modified zeolite, 100-150 parts of organic fertilizer, 15-25 parts of desulfurated plaster, lime
60-80 parts of stone, 12-15 parts of Phos, 100-120 parts of sludge, 1-2 parts of microorganism formulation；Heavy metal soil conditioner is not only right
Heavy metal ion in soil has notable, efficiently and rapidly absorption degradation effect, reduces containing for the heavy metal ion in soil
Amount, while soil texture, the Tiny ecosystem in improvement soil, the effect for strengthening soil fertility can also be improved, it is a kind of efficient, honest and clean
The heavy metal contaminated soil conditioner of valency.
A kind of preparation method of heavy metal contaminated soil conditioner, including：Salt is modified, acid is modified, high temperature modified, compost,
Compounding, specifically includes following steps：
