Problems solved by technology

[0005] Pickling is a kind of chemical leaching technology. Chemical acids such as sulfuric acid and hydrochloric acid are often used for pickling. These chemical acid leaching effects are very good, but they often cause secondary pollution, which can easily penetrate into groundwater and kill soil. The microorganisms in the soil reduce the nutrient content of the soil, which is very destructive to the soil, often resulting in the soil not growing, which is not conducive to the removal of heavy metals in the cultivated soil

preparation example Construction

[0027] A preparation method of a heavy metal ecological stripping agent, the specific steps are as follows:

[0028] The first step: mix xytosan, dextran, xylitol, mucopolysaccharide, amino acid, potassium dihydrogen phosphate, and 100% pure water according to the above weight and part ratio, and use it as a culture medium for later use;

[0029] Step 2: Use one or more of MRS agar medium and EB medium to ferment lactic acid bacteria alone, and the effective number of viable lactic acid bacteria after fermentation is ≥ 200 million / ml. Lactic acid bacteria fermentation conditions are temperature 25°C-30°C, pH 4.5-5.5, ferment for 3-4 days to obtain lactic acid bacteria fermentation products;

[0030] Use one or more of beef extract peptone medium, potato medium, and butyric acid bacteria medium to ferment butyric acid bacteria alone. After fermentation, the effective number of butyric acid bacteria is ≥ 200 million / ml. Bacterial fermentation conditions are temperature 25°C-28°...

Embodiment 1

[0034] Embodiment 1 is a kind of heavy metal ecological stripping agent and preparation method, specifically as follows:

[0035] Soil water-retaining organic fertilizer includes the following ingredients: 5 parts of xyloxan, 10 parts of dextran, 5 parts of xylitol, 55 parts of mucopolysaccharide, 10 parts of amino acid, 5 parts of potassium dihydrogen phosphate, 5 parts of lactic acid bacteria and fermentation products, 5 parts butyric acid bacteria and fermentation products, and 950 parts of purified water.

[0036] Step 1: Mix xytosan, dextran, xylitol, mucopolysaccharide, amino acid, potassium dihydrogen phosphate, and 100% pure water evenly according to the above-mentioned ratio of parts by weight, and use it as a culture medium for future use.

[0037] Step 2: Use MRS agar medium to ferment lactic acid bacteria alone, and the number of effective viable lactic acid bacteria after fermentation is ≥ 200 million / ml. The fermentation conditions of the lactic acid bacteria ar...

Abstract

The invention discloses a heavy metal ecological dissolving agent, which comprises the following raw materials in parts by weight: 5-15 parts of xylooligosaccharide, 10-20 parts of glucan, 5-15 partsof xylitol, 5-15 parts of mucopolysaccharide, 10-20 parts of compound amino acid, 5-10 parts of mono potassium phosphate, 5- 10 parts of Lactobacillus fermentation product, 5-10 parts of Clostridium butyricum fermentation product, 885-950 parts of purified water. The invention is cheap in price and safe in environment, the raw materials required by the invention are convenient and easy to be purchased everywhere, and the cost is low; the raw materials adopted by the invention are originally drawn from crop by-products and mixed with fermentation products of beneficial microorganisms to be prepared. After being applied to soil, the raw materials can be completely decomposed, the soil moisture content cannot be maintained, and the nutrients required by crops can be provided.

Description

technical field [0001] The invention relates to the field of soil heavy metal treatment, in particular to a heavy metal ecological stripping agent and a preparation method thereof. Background technique [0002] Because heavy metal pollution has caused a major threat to human survival and health, countries around the world have formulated corresponding laws and regulations to strictly limit the discharge of heavy metals and reduce environmental pollution caused by heavy metals. At the same time, comprehensive treatment will be carried out on the polluted areas to reduce the harm of heavy metals. At present, the remediation of heavy metal contaminated soil mainly adopts physical, chemical remediation technology and biological remediation technology. [0003] The physical method is to use a series of physical means (such as soil engineering, electrothermal analysis repair method, etc.) to remove or separate the pollutants in the soil. Generally, the chemical method is used in ...
