Abstract
The invention discloses a soil heavy metal passivator, which is prepared from the following materials in parts by mass: 10 to 15 parts of pulverized fuel ash, 10 to 15 parts of sapropel, 20 to 25 parts of grass carbon, 10 to 15 parts of charcoal, 5 to 15 parts of alkali, 5 to 15 parts of slaked lime, and 100 to 150 parts of water. The soil heavy metal passivator provided by the invention can well neutralize heavy metal in soil, so that the content of the heavy metal in the soil can be at normal standard, and the plants can be grown healthily. The soil heavy metal passivator is lower in preparation cost and suitable for popularization and use.
Description
Technical field
The present invention relates to a kind of soil heavy metal passivant.
Background technology
Heavy metal pollution of soil problem mainly has two big classes, 1, the exploitation in mine and smelting, the water and soil heavy metal pollution caused, 2, chemical fertilizer for years use the soil acidification caused and heavy metal pollution in a large number.Duo Diduo provinces and cities, the especially Yangtze river basin and areas to the south, crop heavy metals exceeding standard problem is increasingly severe, so that defining serious social problem.At present, large-area heavy metal pollution of soil rehabilitation cost is high, and effect is low, lacks effective governing measure, and China's ecological environment is asked day by day serious, is badly in need of a kind of low cost, effective treatment technology.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of soil heavy metal passivant, and the present invention can the preferable heavy metal in sweetening of the soil so that the content of beary metal in soil is in arm's length standard, has surplus energy plant growing.
For solving the problems referred to above, the present invention adopts the following technical scheme that
A kind of soil heavy metal passivant, including the material of following mass fraction: flyash 10-15 part, sapropel 10-15 part, peat composed of rotten mosses 20-25 part, Linesless charcoal 10-15 part, alkali 5-15 part, Calx 5-15 part and water 100-150 part.
Preferably, including the material of following mass fraction: 10 parts of flyash, sapropel 15 parts, the peat composed of rotten mosses 25 parts, 15 parts of Linesless charcoal, 15 parts of alkali, Calx 5 parts and 150 parts of water.
Preferably, including the material of following mass fraction: 15 parts of flyash, sapropel 10 parts, the peat composed of rotten mosses 25 parts, 10 parts of Linesless charcoal, 15 parts of alkali, Calx 5 parts and 100 parts of water.
Preferably, including the material of following mass fraction: 12 parts of flyash, sapropel 10 parts, the peat composed of rotten mosses 25 parts, 10 parts of Linesless charcoal, 15 parts of alkali, Calx 10 parts and 120 parts of water.
Preferably, including the material of following mass fraction: 12 parts of flyash, sapropel 10 parts, the peat composed of rotten mosses 22 parts, 13 parts of Linesless charcoal, 10 parts of alkali, Calx 10 parts and 120 parts of water.
The preparation method of a kind of soil heavy metal passivant, comprises the following steps:
1) choose flyash 10-15 part, sapropel 10-15 part, peat composed of rotten mosses 20-25 part, Linesless charcoal 10-15 part and alkali 5-15 part, selected each component uniformly mixed, incorporation time 15-25min, obtain mixture:
2) mixture in step 1) adds Calx 5-15 part, then mix 5-15min, add water 100-150 part after having mixed, remix 10-15min, stand 30-40min after having mixed, i.e. obtain the soil heavy metal passivant of the present invention.
The invention has the beneficial effects as follows: the present invention can the preferable heavy metal in sweetening of the soil so that the content of beary metal in soil is in arm's length standard, has surplus energy plant growing, and the preparation cost of the present invention is the cheapest, is suitable for promoting the use of.
