Problems solved by technology

[0002] my country has a vast area of ​​arable land, but it is also one of the most serious soil pollution hazards. In the past, in order to one-sidedly pursue economic interests, a large amount of chemical plant waste, garbage generated by people's daily life, and pesticides used in planting were randomly discharged. , seriously polluted the surrounding land and rivers, caused a sharp deterioration of the soil, affected the normal growth of vegetation, and brought a devastating blow to ecological restoration

Embodiment 1

[0025] Example one , One of the preparation of soil remediation modifier

[0026] a. According to the weight ratio of 29:14:19, nano-humic acid, micronized serpentine and micronized diatomaceous earth, and sequentially added to the mixer to mix;

[0027] b. Prepare a composite water retaining agent with a material weight ratio of 4 in step a: weigh 70 parts by weight of acrylic acid and neutralize it with NaOH (fully mix and dissolve) to form an acrylic monomer solution; weigh 2 parts by weight of carboxymethyl Sodium base cellulose is dissolved in distilled water until it is fully dissolved, and an appropriate amount of tourmaline of 6 parts by weight and 20 parts by weight of wheat bran are added to it, and after the dispersion is uniform, 2 parts by weight of crosslinking agent N, N'- sub Methyl bisacrylamide and 1.5 parts by weight of the initiator potassium persulfate form a wheat bran mixed solution; under constant temperature and mechanical stirring, add the acrylic monomer ...

Embodiment 2

[0030] Example two , Preparation of Soil Remediation Amendment II

[0031] a. According to the weight ratio of 33:10:15, nano-humic acid, micronized serpentine and micronized diatomaceous earth, and sequentially added to the mixer to mix;

[0032] b. Prepare a composite water retaining agent with a material weight ratio of 6 in step a: weigh 80 parts by weight of acrylic acid and neutralize it with NaOH (fully mix and dissolve) to form an acrylic monomer solution; weigh 1 part by weight of carboxymethyl Sodium base cellulose is dissolved in distilled water to fully dissolve, add 4 parts by weight of tourmaline and 10 parts by weight of wheat bran, and then add 2 parts by weight of crosslinking agent N,N'- Methyl bisacrylamide and 0.5 parts by weight of the initiator potassium persulfate form a wheat bran mixed solution; under constant temperature and mechanical stirring, add the acrylic monomer solution to the wheat bran mixture until gelation occurs Stop stirring and react for 3...

Embodiment 3

[0035] Example three , The third preparation of soil remediation amendment

[0036] a. According to the weight ratio of 31:12:17, nano-humic acid, micronized serpentine and micronized diatomaceous earth, and sequentially added to the mixer to mix;

[0037] b. Prepare a composite water retaining agent with a material weight ratio of 5 in step a: weigh 75 parts by weight of acrylic acid and neutralize with NaOH (fully mix and dissolve) to form an acrylic monomer solution; weigh 1.5 parts by weight of carboxymethyl Sodium cellulose is dissolved in distilled water until it is fully dissolved, and an appropriate amount of tourmaline of 5 parts by weight and wheat bran of 15 parts by weight are added to it, and after the dispersion is uniform, 1.5 parts by weight of crosslinking agent N, N'- sub Methyl bisacrylamide and 1.0 parts by weight of the initiator potassium persulfate form a wheat bran mixed solution; under constant temperature and mechanical stirring, add the acrylic monomer s...

Abstract

The invention discloses an improver for soil remediation. The improver comprises nanometer humic acid, micronized serpentine, diatomite micro-powder, a composite water retaining agent and a microbialpowder according to a weight ratio of (29-33):(10-14):(15-19):(4-6):(0.5-1.5). The invention also discloses a preparation method of the improver for soil remediation. The improver for soil remediationcan effectively increase the aggregate structure of soil, improve the void condition of soil, improve the nutrient content and the water retention and fertilizer conservation capability of the soil,reduce the content of heavy metals and organic pollutants in the soil and promote the growth of plants and microorganisms, and is conductive to ecological restoration of contaminated soil.

Description

Technical field [0001] The invention belongs to the technical field of soil improvement, and specifically relates to an amendment for soil restoration and a preparation method thereof. Background technique [0002] my country has a vast area of ​​arable land, but it is also one of the countries where the soil is the most severely affected by various pollution. In the past, in order to pursue economic benefits one-sidedly, a large amount of chemical plant waste, garbage generated in people’s daily life, and pesticides used in planting were discharged randomly. , Seriously polluting the surrounding land and rivers, causing rapid soil deterioration, affecting the normal growth of vegetation, and bringing a devastating blow to ecological restoration. [0003] At present, the following methods are commonly used for the treatment of combined pollution of these heavy metals and organic pollutants: physical and chemical combined remediation method, chemical and biological combined remediati...
