1. a treatment unit for ammonia-containing water, is characterized in that, it possesses:

  • Ammonia stripping processing mechanism, it carries out the process of ammonia stripping at more than pH10 to ammonia-containing water;

    A reverse osmosis membrane processing mechanism, it carries out the reverse osmosis membrane processing of the first step at more than pH10 to the ammonia stripping process water after the process of described ammonia stripping, thus is separated into once through water and once concentration water;

    Secondary counter permeable membrane processing mechanism, it to described reverse osmosis membrane processing of once carrying out second step through water, thus is separated into secondary through water and secondary concentration water at below pH8.5;

    AndCycling mechanism, described secondary concentration water is recycled to the upstream side of described ammonia stripping processing mechanism by it.
