Embodiment 1

[0024] In September in autumn, harvest common field weeds, stalks and reeds on the side of the field road, ditch, wasteland, sand dunes or salinized sandy texture, and soak them in water for 4 hours;

[0025] On the saline-alkali ground, dig a pit with a depth of 100cm and a pit length×width=1500×1500cm. Spread the pre-soaked reed straw on the bottom of the pit with a thickness of 5cm, and then fill the excavated soil back and compact it;

[0026] In April of the next spring, build a ditch at the place where the pit is dug, with a width of 35cm in the ditch, a height of 35cm in the ridge, and a width of 20cm, and connect the ditch with the ditch;

[0027] Stir 150 g of a commercially available water-retaining agent (its main component is: starch grafted acrylate copolymer cross-linked product) into 30 liters of water to prepare a solution with a concentration of 0.5%, stir for 20 minutes, and water temperature is 20°C. After soaking in the solution for 7 hours, spread it evenl...

Embodiment 2

[0034] In September in autumn, harvest field weed straw dogtail grass, which is common in field roadsides, ditch sides, wasteland, dunes or salinized sandy textures, and soak in water for 4 hours;

[0035] On the saline-alkali land, dig a pit with a depth of 100cm and a pit length×width=1500×1500cm. Spread the pre-soaked foxtail grass stalks on the bottom of the pit with a thickness of 5cm, and then fill the excavated soil back and compact it;

[0036] In April of the next spring, build a ditch at the place where the pit is dug, with a width of 45 cm in the ditch, a height of 40 cm in the ridge, and a width of 25 cm, and connect the ditch with the ditch;

[0037]Stir 150g of a commercially available water-retaining agent (its main component is: starch grafted acrylate copolymerized cross-linked product) into 30 liters of water to prepare a solution with a concentration of 0.5%, stir for 20 minutes, and the water temperature is 20°C. After soaking in the solution for 7 hours, s...

Embodiment 3

[0044] In September in autumn, harvest field weed straw barnyardgrass, which is common in field roadsides, ditch sides, wasteland, dunes or salinized sandy textures, and soak in water for 4 hours;

[0045] On the saline-alkali ground, dig a pit with a depth of 100 cm and a pit length × width = 1500 × 1500 cm. Spread pre-soaked barnyardgrass stalks on the bottom of the pit with a thickness of 5 cm, and then fill the excavated soil back and compact it;

[0046] In April of the next spring, build a ditch at the place where the pit is dug, with a width of 45 cm in the ditch, a height of 50 cm in the ridge, and a width of 20 cm, and connect the ditch with the ditch;

[0047] Stir 150 g of a commercially available water-retaining agent (its main component is: starch-grafted acrylate copolymerized cross-linked product) into 30 liters of water to prepare a solution with a concentration of 0.5%, stir for 20 minutes, and water temperature 20 ° C. After soaking in the solution for 7 hour...

Abstract

The invention relates to a method for quickly reducing sulphur-containing waste water pollution by utilizing a halophilous plant. According to the method provided by the invention, plant extracting, plant fixing, straw filtering and plant degrading technologies of the halophilous plant in an arid region are utilized, straws of weeds in the field are effectively utilized to filter and absorb pollutants in sulphur-containing waste water, transferring and spreading of pollution in the soil are effectively prevented; based on the characteristics of salsola collina such as high biomass, short growth cycle, high growth speed and strong bivalent sulfate radical decomposition capacity and through adoption of manual harvesting and ashing treatment, the pollutants are quickly and effectively transferred; and based on the characteristics of Chinese tamarisk such super high drought resistance and good sulphur enrichment performance, the sulphur-containing waste water is reasonably utilized by virtue of landscape reconstruction of eremophyte community, so environmental pollution is effectively reduced.

Description

technical field [0001] The invention relates to a method for utilization of oily sewage and ecological improvement, in particular to a rapid method for reducing pollution of sulfur-containing waste water by using halophytes. Background technique [0002] By the end of 2010, my country's petroleum geological resources were 881×10 8 t, about 3 / 4 of the oil resources in the western arid region have yet to be discovered, and the potential for oil resources is huge. my country's energy security strategy will build a relatively complete original deep processing base in Xinjiang. Under the background of the increasing potential of oil production in the east and the rapid growth of domestic oil demand, the western region, especially Xinjiang, will become my country's most potential onshore oil Replacing the source, the development of oil resources in Xinjiang has been promoted to the primary position of the oil strategy. Xinjiang is located in the arid region of northwest my countr...
