| description | The utility model belongs to the technical field of chemical wastewater treatment, and particularly relates to a high-ammonia-nitrogen-content triethyl orthoformate production wastewater treatment system. In the system provided by the utility model, a wastewater pipeline is connected with a pretreatment tank, the pretreatment tank is connected with a heat exchanger through a pipeline, an alkali liquor pipeline is arranged between the pretreatment tank and the heat exchanger, and the heat exchanger is connected with a deamination membrane treatment device; the deamination membrane treatment device, the filter and the ammonium sulfate circulating tank form a closed loop; the deamination membrane treatment device is also connected with a deamination wastewater post-treatment pipeline; and the outlet of the ammonium sulfate circulating tank is connected with a pipeline leading to a subsequent treatment unit. Compared with a traditional system adopting an ammonia stripping tower and an ammonia absorption tower, th |
