Abstract:
采用盐析凝胶法回收废水中的聚乙烯醇（pva）,并对盐析凝胶后废水进行fenton处理。考察na2so4、na2b4o7·10h2o投加量、ph、温度、反应时间等因素对pva回收效果的影响，同时研究fenton氧化过程中h2o2投加量、ph等因素的作用效果。结果表明:盐析凝胶-fenton氧化法可以有效地回收废水中的pva，并能高效降解废水中的有机物。在室温，ph为4，na2so4投加量为15g/l，na2b4o7·10h2o投加量为2.5g/l，反应60min的条件下，废水中pva回收率可达88.78%；fenton进一步处理后的废水中未检出pva，化学耗氧量（cod）降至298mg/l。
