Description
Technical field
The present invention relates to soil improvement field, be specifically related to a kind of acid soil improving agent being made up of iron ore mine and preparation method thereof.
Background technology
Acid ground is the general name of low ph value soil, including red soil, yellow earth, laterite, red earth and podzolic soil etc..Acid ground is the most widely distributed, is primarily present in rainy Temperate Region in China and tropical and subtropical region.Widely distributed large-area acid ground on the south China the Changjiang river, it is concentrated mainly on the provinces, south such as Zhejiang, Jiangxi, Fujian, Guangdong, Guangxi, Yunnan and Guizhou, also there is distribution in the areas such as Henan, Hebei, Liaoning and the Inner Mongol in northern area, the Yellow River, the gross area about 200,000,000 hectares.
Most acid ground pH value is less than 5.5, and wherein greatly less than 5.0, have is even lower.With China's economy, the development of society, ambient pressure is increasing, and various places report the generation of " acid rain " frequently, and these areas all demonstrating acid ground and acidizing degree have the trend of increase further.
In acid ground, under conditions of precipitation is more, there is strong eluviation in soil, causes K+、Ca2+、Mg2+Deng a large amount of leaching loss of mineral nutrient ion, on the one hand cause crop in default of calcium, magnesium and limiting growth；On the other hand can increase again the acidity of soil, improve the dissolubility of aluminum, discharge a large amount of aluminium ion, form the aluminium compound of plant available form.Plant excessive consumption aluminum, not only reduces the quality of plant product, and the root growth of plant particularly plant can be produced extreme influence, even result in dunsiekte dead.Simultaneously the most in acid condition, not only the micro organism quantity in soil reduces, and the growth of microorganism and activity are also suppressed, thus have impact on the circulation of C, N, P, S in the decomposition of the soil organism and soil.
Mineral resources are human development and one of particularly important material base of surviving, and develop rapidly along with China is industrialized, and barren rock and mine tailing that mineral resources produce during Development and Production also result in serious environmental pollution.According to statistics, being restricted by factors such as technique of preparing level, production equipment, the mine tailing of China's Mining Market has reached more than 10,000,000,000 tons, and has the trend increased year by year, and the utilization rate ratio of mine tailing is relatively low.
Iron ore mine is that Iron Works Plant is under the conditions of specific economic technology, iron ore is levigate, choose the garbage that " useful constituent " discharges afterwards, current China adds up to store up iron ore mine amount and is up to tens00000000 tons, and discharge nearly 300,000,000 tons of iron ore mine every year, comprehensive utilization ratio is less than 20%.A large amount of iron ore mines typically use landfill to dispose, and not only waste resource, tie up soil simultaneously, cause environmental pollution, and in view of above reason, the comprehensive utilization of iron ore mine is extremely necessary.
The present situation of iron ore mine research and utilization is mainly in the following aspects:
Spoil reclaming
Due to the restriction of technical conditions, some mines are the highest due to recovery rate in ore-dressing, and the utilization rate of mineral resources is not enough, use the technical matters improved, select iron ore mine again, extract valuable mineralogical composition therein.
Ceramic material
In iron ore mine, chemical composition mainly has silicon, aluminum, calcium, the oxide of magnesium and a small amount of potassium, sodium, sulfur oxide, wherein the content of silicon and aluminum is higher, it is similar to the main component of ceramic material, a small amount of iron ore mine is added in Production of Ceramics, the performance of pottery can be improved, be mainly used in little scope firing ceramics material, mine tailing ceramic glaze and mine tailing sanitary ware aspect.
Cement
Cement be mainly composed of sial based compound, also it is similar to the main component of iron ore mine, by adding iron ore mine in cement ingredient, not only can be by affecting formation and the mineral composition of clinker, make the material having other characteristics, moreover it is possible to reduce production cost.
Re-vegetation
China has carried out the work studies of reclaiming of vegetation in the later stage eighties to the nineties, Reclamation Technique condition and the airborne dust suppression etc. that are mainly iron ore mine are explored, carried out vegetation experiment simultaneously, have developed " Land Reclamation In Metallurgical Mine specialist system ", provide relevant Reclamation scheme for Different climate condition, different regions, different soils and ore characteristic.
Fertilizer is commonly referred to as garbage and the animal residue of various animal, uses the treatment technology that physics, chemistry, biology or three have concurrently, through certain processing technique, eliminates harmful substance therein and reaches innoxious standard and the class fertilizer that formed.Fertilizer effect in agricultural production shows improvement soil and improves on utilization rate of fertilizer.
Improvement soil refers mainly to after fertilizer is manured into soil, can effectively improve physics and chemistry situation and the biological nature of soil, vegetable soil, strengthen the fertilizer supply and preservation ability of soil, and good edaphic condition is created in the growth for crop.It is many that fertilizer contains nutrient, but relative amount is low, and release is slow, and the nutrient content of chemical fertilizer is high, and composition is few, and release is fast.Both combine reasonable coordination and use, and are complementary to one another, and promote soil and the dissolving of chemical fertilizer mineral nutrient, and fertilizer and chemical fertilizer are mutually promoted, beneficially Crop, thus improve the utilization rate of fertilizer.
In the application for a patent for invention of Application No. CN201310028566.0, disclose the preparation method of a kind of acid soil improvement conditioner, the preparation method of this conditioner is grey as raw material with the leftover bits and pieces alkaline soil plant of bio-power plant, by this alkaline soil plant ash and calcium magnesium phosphate and furfural dregs mixing and stirring, it is finished product when the parts by weight of moisture are 15-18%.Wherein, the parts by weight of each raw material are: alkaline soil plant ash 60-80%, calcium magnesium phosphate 20-30%, furfural dregs 10-20%.The furfural dregs used in the acid soil improvement conditioner of this disclosure of the invention is acid, and salt content is high, the DeGrain when improveing acid ground, and use causes soil salt content high in a large number, is unfavorable for the growth of crops in soil.
In the application for a patent for invention of Application No. CN201210277844.1, disclosing a kind of soil conditioner and preparation method thereof, this modifying agent includes the component of following weight proportion: gangue 6-12 part, straw 8-16 part, ground phosphate rock 0.2-3 part.The soil conditioner of this disclosure of the invention is relatively suitable for the soil that phosphorus lacks, but this modifying agent is relatively low to the micronutrient levels ratio that crops are useful, it is difficult to improvement acid ground.
