Problems solved by technology

However, Spartina alterniflora is a salt marsh plant that grows in the intertidal zone, and has a high salt content, which is one of the important limiting factors for the complete resource utilization of Spartina alterniflora
[0004] At present, studies on the utilization of Spartina alterniflora resources rarely consider the possible secondary environmental impacts of its high salt content
Only the method of washing the surface with clean water is used randomly, which can only remove the surface salt, and the desalination effect is poor; there are also studies that use steam fermentation for desalination treatment, although the desalination effect is better, but the cost is high and the operation is more complicated
Therefore, in the current resource utilization of Spartina alterniflora, there is a lack of a low-cost, efficient and convenient desalination method and desalination equipment

Embodiment 1

[0043] Source of raw materials: samples of Spartina alterniflora standing dead from the mouth of the Yellow River.

[0044] S1. Plant sample pretreatment:

[0045] Wash the dead branches of Spartina alterniflora 3 times with clean water to remove impurities such as gravel and soil, and place them in a ventilated and shaded place to dry naturally; cut the air-dried Spartina alterniflora dead branches into small pieces with a length less than 0.5cm for later use .

[0046] S2. Set the clean water desalination method, solid-liquid ratio, desalination temperature and desalination time as experimental factors, and set different levels for each experimental factor: the clean water desalination method includes two levels of oscillation and non-oscillation, and the solid-liquid ratio is set to 4 levels, respectively 1g:15mL, 1g:20mL, 1g:25mL and 1g:30mL; the desalination temperature is set to 5 levels, respectively 20°C, 30°C, 40°C, 50°C and 60°C; The above desalination time is set ...

Embodiment 2

[0064] Raw material source: Fresh samples of Spartina alterniflora from the Yellow River Estuary.

[0065] S1. Plant sample pretreatment:

[0066] Wash the fresh Spartina alterniflora samples 3 times with clean water to remove impurities such as gravel and soil, and place them in a ventilated and cool place to air dry naturally; cut the air-dried fresh Spartina alterniflora branches into small pieces with a length less than 0.5 cm for later use.

[0067] S2. Set the clean water desalination method, solid-liquid ratio, desalination temperature and desalination time as experimental factors, and set different levels for each experimental factor: the clean water desalination method includes two levels of oscillation and non-oscillation, and the solid-liquid ratio is set to 4 levels, respectively 1g:15mL, 1g:20mL, 1g:25mL and 1g:30mL; the desalination temperature is set to 5 levels, respectively 20°C, 30°C, 40°C, 50°C and 60°C; The above desalination time is set to 6 levels, namel...

Abstract

The invention provides a desalination device for Spartina alterniflora, which includes a desalination bin, a two-way valve, an automatic controller, a salinity detection system, a reverse osmosis system, a peristaltic pump and connecting water pipes. An optimization method for desalination of Spartina alterniflora, including: S1. Pretreatment of Spartina alterniflora samples; S2. Setting water desalination method, solid-liquid ratio and desalination time as experimental factors, and setting different levels; S3. Designing multiple groups The desalination experiment was carried out under the experimental conditions of horizontal combination; S4. Turn on the desalination equipment of Spartina alterniflora, put the pretreated Spartina alterniflora into the desalination bin, conduct experiments according to multiple groups of horizontal combination experimental conditions, and monitor the water after the experiment is over. Salt content; S5. Analyze the experimental results and select the best combination of levels, which is the best process parameter. The desalination equipment and the desalination optimization method provided by the invention not only have the advantages of simple operation, low cost, high desalination rate and high recovery rate of brine after desalination treatment.

Description

technical field [0001] The invention relates to the field of resource utilization of Spartina alterniflora, in particular to a desalination optimization method and equipment for Spartina alterniflora. Background technique [0002] Spartina alterniflora (Spartina alterniflora) belongs to the Poaceae family and is a perennial herb that mostly grows in estuaries and intertidal zones, and is native to the Atlantic and Gulf coasts of the United States. It has been introduced and planted in many countries because of its ecological functions such as reducing silt and making land, protecting beaches and embankments. However, due to its strong reproductive ability and lack of natural enemies, it often forms a single dominant species community after introduction, which destroys the ecological balance of the introduced area, threatens local biodiversity, and even causes the extinction of local species. It has been listed as an invasive plant by many countries and strictly controlled. ...
