摘　　要：采用膜法除硝时,淡盐水在进膜前需降温处理,造成大量的热量被循环水带走;在北方的氯碱企业,由于回用部分废水,加之冬天较为寒冷,在化盐时,还要用蒸汽加热。为降低能量损失,采用一种耐高温膜对50~80℃淡盐水进行除硝试验,该膜在测试中表现出良好的性能。When sulfate is removed by membrane method,the depleted brine needs to be cooled before entering the membrane,causing a large amount of heat to be taken away by circulating water.In the chlor-alkali enterprises in the north,due to the reuse of some wastewater and the cold weather in winter,it is necessary to heat with steam when dissolving salt.In order to reduce energy loss,a high temperature resistant membrane is tested for removal of sulfate from depleted brine at 50-80℃.The membrane shows good performance in the test.
