The high-salt wastewater is the wastewater with a total salt content of at least 1%, mainly from chemical plants, oil and gas collection and processing, etc.The wastewater contains many substances, including salt, oil, organic heavy metals and radioactive substances.There are a wide range of ways to produce salt-containing wastewater, and the amount of water increases year by year.Therefore, it is very important to find an efficient industrial wastewater treatment and disposal technology.How to treat the high salt wastewater from industrial production effectively?Salt purification is a big industry problem.Most of the enterprises in our country mainly treat the high-salt wastewater by removing organic matter and desalting.Commonly used methods mainly include distillation, membrane separation, microfiltration, biological treatment technology or simple incineration, but these methods are either difficult to operate, or treatment cost is expensive, and can not purify the salt, so the solution effect is not ideal.

Chemical high salt wastewater treatment is very complex, containing a large number of benzene ring or other heterocyclic organic matter, some of which high color, high COD, need to be treated, can not be directly discharged.In the process of high-salt wastewater treatment, all kinds of purification salt treatment methods can not achieve the purpose of removing color and COD at the same time.At present, the best balance between the treatment effect and the economic cost is the development direction of the treatment of high-salt wastewater.

The professional wastewater treatment process can meet the following requirements of the enterprise customers who produce high-salt wastewater for wastewater treatment:

(1)Efficient and stable removal of non-ferrous substances in wastewater, effective removal of high chemical oxygen demand, purification of salt;

(2)Low investment cost, low operation cost, convenient operation and maintenance of equipment;

(3)Advanced and reliable technology, no secondary pollution.

The principle of the adsorption process is to selectively adsorb the components or substances to be removed by using special adsorption materials developed.When the adsorption is saturated, the adsorption material is desorbed with a specific desorption agent, the adsorption material is regenerated, and so on.
