Description

Technical Field

[0001] The utility model relates to the technical field of high-salt wastewater from coal chemical industry, in particular to a device for treating high-salt wastewater from coal chemical industry by using a membrane separation method. Background Art

[0002] High-salt wastewater from coal chemical industry mainly comes from coal gasification, coal liquefaction, methanol synthesis, fertilizer production and other processes. Its characteristics mainly include the following aspects: High salt content: The salt content of high-salt wastewater from coal chemical industry can usually reach 3000~15000mg / L, which is much higher than general wastewater. Complex water quality: The wastewater not only contains a large amount of organic matter, such as benzene, phenol, nitrogen-containing heterocyclic compounds, polycyclic aromatic hydrocarbons and other difficult-to-degrade organic pollutants, but also contains a variety of inorganic salts, such as Na+, Ca2+, K+, Mg2+, Fe2+, Mn2+, Al3+, Cl-, SO42-, NO3-, F- and other inorganic ions, among which the content of Na+, Cl-, and SO42- is much higher than other ions, accounting for more than 90% of the total amount of inorganic ions. High hardness, high alkalinity, and high corrosiveness: Because the wastewater contains a large amount of inorganic salts, it has high hardness, alkalinity and corrosiveness, which can easily cause corrosion and blockage to treatment equipment and pipelines. Difficulty in treatment: Since the wastewater contains a large amount of difficult-to-degrade organic matter and inorganic salts, it is difficult to treat and requires a combination of multiple technologies. The treatment process of high-salt wastewater in coal chemical industry mainly includes pretreatment process, resource recovery and reduction treatment, and deep treatment. The pretreatment process mainly removes most of the inorganic salts and suspended matter in the wastewater through desalination pretreatment, precipitation and flocculation, thereby reducing the pressure of subsequent treatment. Resource recovery and reduction treatment recovers valuable substances in the wastewater through multi-effect evaporation crystallization technology, crystal salt thermal melting technology, heavy metal ion solidification technology and other means, while reducing the salt and organic content in the wastewater. Deep treatment uses advanced oxidation technology, biological treatment technology and other means to further remove organic matter and inorganic salts in the wastewater to meet emission standards.

[0003] The patent number disclosed in the China Patent Network is: CN218231925U. The utility model discloses a coal chemical high-salt wastewater treatment device, including a support platform, a stirring box and a filter box. The stirring box is fixedly installed on the upper side of the support platform, and a feed port is fixedly installed on the top of the stirring box. A stirring device is fixedly installed on the upper side of the stirring box. The stirring device is composed of a motor, a rotating shaft, a gear shaft, a rotating gear, a stirring shaft and a stirring blade. The utility model stirs the high-salt wastewater by setting the stirring device, which can accelerate the evaporation efficiency of the high-salt wastewater, thereby improving the treatment efficiency of the device for the high-salt wastewater and improving the work efficiency of the staff. A hot air blower, an air inlet pipe, a heating box, a heating wire, a hot air pipe, a heating plate and an air outlet are arranged to heat the raw material to make it evaporate continuously. The compressed steam after heat exchange forms a condensate, which can increase the flow rate of the steam and enable the steam to quickly enter the filter box.
