摘要
对膜法除硝工艺进行了改造,将低硝盐水由原送去化盐改为与进膜法脱硝装置的淡盐水混合,实际脱硝量由652.9 kg/h提升到734.5 kg/h。
In the old membrane process for sodium sulfate removal, the brine of a low sulfate content was delivered to dissolve raw salt. In the improved process, the brine of a low sulfate content mixed with the dilute brine feeding into the membrane process device. Then, the removal amount of sodium sulfate increased from 652.9 to 734.5 kg/h.
