Embodiment 1

[0035] 1. Pour pine crude product residue (COD greater than 150,000) into reaction tanks 1 and 2, add 30% lye in storage tank 16 into the reaction tank to adjust the pH to 13-13.5, stir for 10-30min, and let stand for 30-60min Post liquid;

[0036] 2. In step 1, the organic phase is triethylamine, which is filtered through the plate frame 4 and enters the storage tank 3 for recovery;

[0037] 3. The water phase in step 1 enters the tank 5, extracts and stirs with 0.3 times dichloromethane for 10-15 minutes, and then stands still for 15-30 minutes to separate the phases;

[0038] 4. In step 3, the organic phase enters storage tank 6 to be distilled;

[0039] 5. Add the 30% hydrochloric acid in the storage tank 17 to the reaction tanks 8 and 12, adjust the pH to 1.9-2.1, stir for 10-30 minutes, and enter the centrifuge 9 for centrifugation to obtain the accelerator M;

[0040] 6. The centrate liquid in step 5 enters the storage tank 10, adds activated carbon at room temperature ...

Abstract

The invention discloses a treatment device of ceftriaxone synthesis pharmaceutical production waste water. The treatment device comprises four sets of reaction tanks, three sets of storage tanks, one set of liquid caustic soda tank, one set of liquid acid tank, a separation and purification device, a recovery device, and a pipeline pump and a valve. According to a treatment method, ceftriaxone crude product kettle residue liquid is delivered into a treatment system via the first set reaction tank, and then is delivered through the second set reaction tank, the third set reaction tank, and the fourth set reaction tank respectively.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a treatment device and method for cephalosporin wastewater. Background technique [0002] Ceftriaxone (also known as ceftriaxone) is a third-generation broad-spectrum, high-efficiency, long-acting, low-toxic injection cephalosporin, which is widely used in clinical practice. At present, the main synthetic route is to use 7-aminocephalosporanic acid (7-ACA) as raw material to react with thiotriazine to generate 7-aminocefatriazine (7-ACT), and then react with aminothioxime active thioester to generate Ceftriaxone. According to the production raw materials and process characteristics, this type of wastewater has complex components, high concentration of organic matter, and contains refractory substances and inhibitory antibiotics. These components are mostly toxic substances, and the nitrogen elements in them are very likely to be nitrosated. If it is discharged into the water...
