Embodiment 1

[0019] Such as figure 1 Shown, a kind of clindamycin hydrochloride waste water treatment process, it comprises the following steps: step (1) clindamycin hydrochloride waste water is intercepted to remove float and bulk impurity through the artificial grid in the grid ditch; ) the treated wastewater enters the regulating tank, and the wastewater volume and water quality are adjusted in the regulating tank; step (3) the wastewater is pumped into the stripping tower to remove the volatile liquid, and the gas stripped out is blown out with a gas absorption device Absorption, the waste water after stripping is discharged into the regulating pool; step (4) heats the waste water after stripping in the regulating pool, and reacts for a certain period of time so that the DMF in the waste water is fully decomposed, and the generated dimethylamine gas is statically absorbed by water , fully dissolved to generate an aqueous solution of dimethylamine, which is stored in a storage tank; in ...

Abstract

The invention relates to a clindamycin hydrochloride waste water processing technology. The processing technology comprises the following steps: firstly, waste water is intercepted, and floaters and block impurities are removed; secondary, water volume, water quality and pH of waste water are adjusted in an adjusting tank; thirdly, volatile liquids of chloroform, acetone, ethanol and the like are removed through air stripping; fourthly, dimethylamine gas generated from a heating reaction is absorbed by water in a static state and a dimethylamine agueous solution is generated; fifthly, residual clindamycin and other small particle substances are recovered through an ultrafiltration device; sixthly, the waste water after ultrafiltration goes into an electrodialysis device and is subjected to desalting processing; seventhly, the filtrate after electrodialysis is subjected to biochemistry treatment; eighthly, the filtrate after biochemistry treatment is filtered and recycled. The provided processing technology has advantages of simple technology, simple operation, high processing efficiency, low device operation expense, resource recycle, solves the standard meeting discharge and recycle problems of clindamycin hydrochloride waste water, and can bring about extra economic benefits.

Description

technical field [0001] The patent of the invention belongs to the technical field of wastewater treatment, and in particular relates to a clindamycin hydrochloride wastewater treatment process. Background technique [0002] As an antibiotic drug, clindamycin hydrochloride is a semi-synthetic derivative of lincomycin hydrochloride, which is mainly used to treat infections caused by anaerobic bacteria, staphylococcus, streptococcus, pneumococcus, etc. Mycin is 4 to 8 times stronger, and the current market demand is increasing year by year. Its synthesis methods include triphenylphosphine route and DMF route. At present, the DMF synthesis route using lincomycin hydrochloride as raw material is mostly used in industry, and it is produced through chlorination reaction, hydrolysis reaction, water washing, concentrated crystallization, dealcoholization reaction, and refined crystallization. become. [0003] Clindamycin hydrochloride produces a large amount of wastewater during th...
