Description

The application of straw ammonium sulfite liquor in control sandstorm and Desertification Soil

I technical field

The present invention relates to the purposes of stalk and timber neutral ammonium sulfite process waste liquid, particularly relate to it by spraying and irrigating sandy soil ground surface, thus play moistening between sandy soil particle, bond, dry solidification, bonding fixing agent (be called for short cement, often claim sand-fixation agent) the active application of the fixing grains of sand and soil.This invention is in order to sand-fixation soil-retention, control sandstorm and administer Desertification Soil, and stretches further and expand.The present invention should belong to Land Resources Exploitation and field of environment protection.

II background technology

China's desert and Gobi area 1,260,000 square kilometres, Desertification Soil area 2,670,000 square kilometres, accounts for 27.9% of the State owned land total area, and the whole nation about has 400,000,000 populations to be subject to desertification impact, is mainly distributed in NORTHWEST CHINA and North China.If the ground such as Beijing, Tianjin is whenever winter, spring, arid is blown often has dust and sand weather, just sandstorm is there is time serious, ground sky sweeps huge wind, to carry under one's arms a large amount of sand and dust, stuffy, it is dusk, visibility meter tens meters, over one hundred rice, make a big impact to environment, traffic, construction and people's lives.

Make annual sandy land area with more than 3000 square kilometres of expansions, cause and area can be utilized to be nibbled, soil depletion, productivity declines, and affects grain-production safety.And the country such as evil and Japan, Korea S.

The strong dust weather in 19 to 20 March in 2010 has swept across half China, and far away and Taiwan Province, about 2.7 hundred million people are subject to the evil of sand and dust.Therefore, control sandstorm, break off sand and dust former, fix the sand, sand changes and administer Desertification Soil, become the major issue of the task of top priority, be also subject to neighbouring country---the attention of Japanese, Korea S.

One, the at present application of sand-fixation method and brief introduction:

(1) engineering fixes the sand method: cost is high and investment is large, is generally of little use.

(2) sand consolidation with biologic method: be planting trees and grass on desert, sand ground and desertification area, tree can be kept out the wind and be reduced wind speed, wind-force, and grass can be taken root and be fixed the sand, and cauline leaf covers ground, not easily by wind erosion sandy land.Therefore, planting trees and grass sand consolidation with biologic is effective method, and is widely adopted.But this method success, is to ensure full stand and grow to set grass.For this reason, except for except the moisture needed for plant-growth and nutrient, also have the chemical sand-fixing materials coordinating and spray and do not endanger plant fertility, fixing sandy soil were eroded with anti-seedling stage, blew away seedling, ensured full stand.

(3) chemical sand-fixing method: chemical sand-fixing method sprays peptizer to fix the sand, such as with emulsified bitumen or crude oil, synthetic resins and inorganic or organic latex and etc. article, sprinkling is fixed the sand, and external result of use is fair.But it is high to there is cost, insufficient raw material, microbiological deterioration is difficult, and the difficult problem to combine with sand consolidation with biologic measure etc.
