Apparatus to recycle waste ammonia water from L-hydroxyproline production and treatment method of apparatus

Abstract

The invention belongs to the technical field of waste ammonia water recycling and relates to an apparatus to recycle waste ammonia water from L-hydroxyproline production and a treatment method of theapparatus. The apparatus and the treatment method are characterized in that the apparatus comprises blow-off tank (2) and a cyclic adsorbing device, waste ammonia water incoming pipe (22) is connectedto the top of the blow-off tank (2) and is provided with a waste ammonia water incoming valve, a discharge port of the blow-off tank (2) is communicated with the cyclic adsorbing device, a dischargeport of the cyclic adsorbing device is connected with ammonia water outgoing pipe (20), blow-down pipe (13) is connected to the bottom of the blow-off tank (2), a blow-off tank blow-down valve is arranged between the blow-off tank (2) and the blow-down pipe (13), and the cyclic adsorbing device is connected with purified water incoming pipe (16). The apparatus herein helps solve the problem that direct emission of waste ammonia water causes environmental pollution and reduce the production cost for enterprises; the treatment method helps recycle ammonia gas, thereby avoiding the environmentalpollution due to direct emission of waste ammonia water.

Description

technical field [0001] The invention discloses a waste ammonia water recovery and treatment device and a treatment method in the production of L-hydroxyproline, belonging to the technical field of waste ammonia water recovery. Background technique [0002] The separation process is to use ion exchange resin to adsorb the product, and then use ammonia water to elute the product to remove impurities and purify the product. How to deal with the waste ammonia water generated in the process is a problem that must be considered. If it is directly treated in environmental protection sewage, due to Due to the amount and concentration of ammonia water, the current sewage treatment is not able to bear it, and the direct discharge will cause great pollution to the environment, and also greatly increase the production cost of the enterprise. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art,...
