择形分子筛无铵交换技术的开发和应用

Develop and Application of the Non-ammonium Exchange Technology of Selective Molecular Sieve Industrial Production

对无铵交换技术在择型分子筛工业生产中的应用情况进行了总结,并对工业试验数据进行了分析对比,结果表明,用非铵盐交换介质代替铵盐介质进行择形分子筛生产,在保证产品质量的前提下实现择型分子筛无铵交换,交换污水全部直接排放,缓解了企业氨氮处理装置压力,降低污水处理费用和生产成本,经济效益和社会效益显著。

Summovvised the selected in the molecular sieve industrial production application situation to the non -ammonium exchange technology, and has carried on the analysis contrast to the commercial test data. The results indicated, replacing the ammonium salt medium with the non -ammonium salt exchange medium to carry on selects the shape molecular sieve production, realized under quality assurance＇s premise selects the molecular sieve non - ammonium exchange, the exchange sewage discharges directly completely, alleviated the enterprise ammonia nitrogen treating plant pressure, reduced the sewage treatment expense and the production cost, the economic efficiency and the social efficiency were remarkable.
