Problems solved by technology

Therefore, a large amount of waste water is produced during the whole boiling process of Osmanthus vetch, which is Osmanthus vetense wastewater, which is mostly discarded in the form of waste. This has caused pollution to the environment on the one hand, and has also caused a lot of waste of resources on the other hand.

Abstract

The invention belongs the technical field of plant extraction and discloses an osmunda waste water treatment liquid as well as a preparation method and application thereof. The content of selenium ions in the osmunda waste water treatment liquid provided by the invention is 0.05 mg / L to 0.30 mg / L. The preparation method of the osmunda waste water treatment liquid comprises the following steps: mixing osmunda with water, heating, and collecting the liquid to obtain osmunda waste water; performing first filtering on the osmunda waste water, collecting a first filter liquor, heating the first filter liquor under the condition of 90 DEG C to 100 DEG C for 30 min to 60 min, adopting an ultrafiltration membrane with the molecular weight cutoff of 20 KDa for second filtering, collecting a second filter liquor, and concentrating to obtain the osmunda waste water treatment liquid. According to the osmunda waste water treatment liquid provided by the invention, osmunda waste water resources are fully utilized, and the preparation technology is simple; in addition, the preparation technology is rich in selenium ions and can be applied to preparation of drugs or drinks containing selenium ions.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a water treatment liquid of weed cabbage, a preparation method and application thereof. Background technique [0002] Osmunda osmanthus, scientific name Osmunda osmanthus, is a perennial herb of Osmanthus genus Osmundaaceae. Weicai is a kind of characteristic vegetable with the same source of medicine and food. Its curly young leaves are rich in nutrition, containing protein, organic minerals and multivitamins. It enjoys the reputation of "pollution-free vegetable" in the world, and it is delicious and Unique flavor, for edible top grade. In traditional Chinese medicine, Osmanthus osmanthus is also known as Osmanthus guanzhong or Gaojiao guanzhong, which has the functions of anti-inflammatory, anti-virus, and improving the body's immunity. Therefore, Weicai is one of the ferns with high economic value at present. However, fresh vetch is easy to age and los...
