Abstract

The invention relates to the field of wastewater treatment, and especially relates to a deamination treatment system. The system comprises a deamination tower, a tower kettle reboiler arranged at the downstream of the deamination tower, a steam compressor arranged at the downstream of the deamination tower, ammonia gas condensing equipment arranged at the downstream of the deamination tower, an ammonia gas absorption tower arranged at the downstream of the deamination tower, and an ammonia water intermediate tank arranged at the downstream of the ammonia gas absorption tower, wherein the deamination treatment system can be switched among a conventional process mode, a tower kettle flash evaporation mode and a tower top compression mode. When a tower kettle flash evaporation mode is used, the type selection range of the steam compressor can be expanded, the method has obvious advantages for projects with large treatment capacity, and the steam consumption is reduced by 63% compared with that of a conventional process mode; when a tower top compression mode is used, the energy utilization rate is the highest, and the steam consumption is reduced by 80% compared with that of a conventional process mode; and for the conventional process mode, the stability of the whole system can be ensured by embedding the system into the two energy-saving processes.

Description

technical field [0001] The invention relates to the field of waste water treatment, in particular to a deammonization treatment system. Background technique [0002] High-salt ammonia-nitrogen wastewater is often produced in the chemical industry. The conventional process adopts the deammonization tower process. The reboiler type and stripping deamination tower have higher deammonization efficiency and greater operating flexibility. The water steam consumption per ton of the conventional deamination process is 100-120kg, and the steam consumption is relatively large, accounting for more than 90% of the overall steam consumption, resulting in high energy consumption for the overall operation. It can be seen that energy saving and emission reduction are particularly important. Contents of the invention [0003] The invention provides a deammonization treatment system to solve the defects of high energy consumption and low energy recycling rate in the prior art. [0004] Th...
