Abstract
The invention provides a separation and extraction system of a high-concentration ciprofloxacin synthetic liquid, which is characterized in that after the pH of a ciprofloxacin synthetic stock solution is adjusted to a proper range by acid or alkali, the operation temperature, pressure and flow are limited, and piperazine and salt serving as additional products are obtained while ciprofloxacin in the ciprofloxacin synthetic stock solution is efficiently extracted by combining an ultrafiltration, a nanofiltration membrane and an evaporation distillation device. The system provided by the invention not only greatly reduces the treatment cost and energy consumption of the traditional process for the water body containing ciprofloxacin, but also generates no secondary pollutant in the separation and extraction process, and the separation and extraction products can be recycled. Therefore, the high-efficiency separation and extraction system of the high-concentration ciprofloxacin synthetic liquid effectively removes and recovers ciprofloxacin and piperazine in the water body, remarkably reduces the treatment cost of the system and the pollution to the environment, and improves the economic benefit and the environmental protection.
