Description
Technical field
The present invention relates to heavy metal to administer field, more particularly to a kind of rice field heavy metal absorbent.
Background technology
Reservoir is one of widely used engineering measure of China's flood control.Being built in flood control zone upper river appropriate location to adjust
The multiple purpose reservoir of flood storage water, using reservoir capacity water conservation, the crest discharge into downstream river course is cut down, reaches deduction and exemption
The purpose of flood damage.Reservoir has two kinds of different modes to the adjustment effect of flood, and one kind plays retention effect of lake, and another kind plays flood storage
Effect.
Heavy metal refers to the metal that proportion is equal to or more than 5.0, such as Fe, Mn, Zn, Cd, Hg, Ni, Co;As is a kind of accurate
Metal, but because its chemical property and environmental behaviour have similarity more with heavy metal, therefore frequently included when discussing heavy metal
Arsenic, some are then directly included into the range of heavy metal.Because iron and manganese content are higher in soil, thus it is generally acknowledged that them
It is not soil pollution element, but under strong reducing condition, the murder by poisoning caused by iron and manganese also causes enough attention.China is multiple
It is exceeded that the rice produced is found cadmium, and soil pollution is into " public hazards ".The appearance of " cadmium rice crisis ", beats soil pollution again
Alarm bell.In the season that amount of rainfall is larger, the water of upstream is washed into reservoir, and life of the reservoir generally also as resident nearby is used
Water.The water quality of reservoir is polluted if subjected to heavy metal pollution, then easily immerse reservoir by rain drop erosion for the soil of upstream.Soil
It is contaminated, after Planting Crops, crops absorb the heavy metal in soil, can cause crop production reduction or the product of crops
Matter is affected.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of rice field heavy metal absorbent, so as to overcome soil by heavy metal pollution,
The inapparent shortcoming of regulation effect.
It is another object of the present invention to provide a kind of preparation method of rice field heavy metal absorbent, and provide rice field
The application method of heavy metal absorbent.
To achieve the above object, the invention provides a kind of rice field heavy metal absorbent, mainly it is made up of following raw material:Mud
