Description
Technical Field
[0001] The utility model relates to the technical field of process wastewater treatment devices, and specifically, to a process wastewater treatment device for a praziquantel production process. Background Art
[0002] Praziquantel is an antiparasitic drug widely used in clinical practice, mainly used to treat diseases such as schistosomiasis and malaria. Its production process mainly includes steps such as preparation, synthesis, crystallization and purification of raw materials. In the production process of praziquantel, the main raw material used is triphenylphosphine, which will undergo hydrolysis during the production process, thus generating a certain amount of praziquantel process wastewater.
[0003] Many existing treatment devices for process wastewater from the production of praziquantel can only perform basic treatment on process wastewater, but have little effect on the treatment of pathogenic microorganisms in the process wastewater, making it impossible to ensure that the quality of the treated water meets the discharge standards.
