Abstract
The invention discloses a soil heavy metal processing agent, and relates to the technical field of soil processing agents. The soil heavy metal processing agent is prepared from the following raw materials: 30-40 parts of sepiolite minerals, 10-20 parts of a plant organic fertilizer additive and 30-40 parts of seaweeds. By adopting the processing agent disclosed by the invention, the soil suffering from metal pollution can be processed, the content of heavy metals in the soil can be rapidly reduced, the soil structure can be changed, and the breeding of microorganisms is promoted.
Description
Technical field
The present invention relates to processing soil treatment agent technical field, especially a kind of heavy metal-polluted soil treatment agent.
Background technology
Soil is one of mankind's Main Natural Resources of depending on for existence, and be also the important component part of human ecological environment, along with the fast development of industry and mining, heavy metal pollution of soil is day by day serious simultaneously.Heavy metal refers to that density is greater than the metal of 4 (g/cm3), exist mainly with compound form at occurring in nature, along with the exploitation of mankind's heavy metal, smelting, processing and mulberry leaf manufacture, make many heavy metals enter in air, water body or soil as lead, cadmium, mercury etc., cause serious heavy metal contamination.Soil is the important natural resources of human survival and development, and the heavy metal contamination of soil will directly affect the health of the mankind and whole TERRESTRIAL ECOSYSTEMS.Heavy metal contamination is different from Organic pollutants, heavy metal itself is difficult to be degraded, the heavy metal entered in soil can not be decomposed by the microorganisms and accumulate for a long time in soil, some enters human body eventually through food chain effect after being absorbed by farm crop, there is certain ecological risk, and these heavy metals easily produce inrichment by plant or animal, current China is by the cultivated area nearly ten million hectare of the heavy metal contaminations such as lead, cadmium, mercury, account for 1/5 of total area under cultivation, grain every year by heavy metal contamination reaches ten million ton, and then causes huge financial loss.The process of heavy metal pollution of soil conventional at present, adopt agriculture state engineering measure, the soil being subject to heavy metal contamination breeds special plant and microorganism, the heavy metal that the plant special by these and microorganism siphon away or degrade in soil, thus reach the object of purification soil, but this method treatment time is grown, it is slow to take effect, the soil of process can be allowed to lose utility value in a long time.Someone proposes to adopt physics, physical and chemical principle to administer heavy-metal contaminated soil, as isolation method, cleaning valve, thermal treatment, electrochemical process etc., solution heavy metal pollution of soil problem that can be quick, thorough, stable, but the disposable input of this method is high, and without investment repayment, be difficult to apply in daily life.
Summary of the invention
Problem to be solved by this invention is to provide a kind of heavy metal-polluted soil treatment agent, and it can reduce the heavy metal content in soil fast, changes Soil structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: it includes the raw material of following weight part: sepiolite group mineral 30-40 part; Plant organic fertilizer feed additives 10-20 part, marine alga 30-40 part.
In technique scheme, scheme can also be more specifically: described sepiolite group mineral be airing air-dry after, grind granulating with shredder, cross 1000-1500 mesh sieve and obtaining.
Further: the liquid that described plant organic fertilizer feed additives is fermented by Radix Glycyrrhizae, rice bran, silkworm excrement through oligosaccharides and dry yeast and obtains.
Further: the ratio of described Radix Glycyrrhizae, rice bran and silkworm excrement is 1:1:2, the oligosaccharides weight added be Radix Glycyrrhizae, rice bran, silkworm excrement gross weight 10%, the dry yeast weight added be Radix Glycyrrhizae, rice bran, silkworm excrement gross weight 15%.
Further: described marine alga is huge marine alga or North Sea marine alga.
Owing to adopting technique scheme, the present invention has following beneficial effect:
The present invention utilizes the porous of sepiolite group mineral, and the beneficial element in sepiolite group mineral replaces out, allows heavy metal element enter in sepiolite group mineral, heavy metal is thoroughly fixedly sealed up for safekeeping, reaches the effect reducing the heavy metal content in soil fast; Marine alga heavy metal has extraordinary adsorption, enter in the soil by heavy metal contamination, the heavy metal in soil can be adsorbed fast, heavy metal is made to lose biological activity by plant organic fertilizer feed additives again, reduce the absorption of plant heavy metal, plant organic fertilizer feed additives can not only provide full nutrition for farm crop simultaneously, increases and upgrades the soil organism, promoting microbial reproduction; And greatly improve utilization rate of fertilizer, the turnover rate of fertilizer nutrient is reduced, promotes the development of plant husbandry.
