摘要： PROBLEM TO BE SOLVED: To provide a method for treating water to be treated containing ammonia which regenerates an ammonia zeolite adsorption layer utilizing an ion-exchange performance by an alkali regenerant to concentrate ammonia into a regenerated liquid in a high concentration. SOLUTION: In the method for passing the water to be treated containing ammonia nitrogen coexisting with a magnesium ion and/or an alkali-earth metal ion through a natural zeolite adsorption column to regenerate zeolite by the alkali regenerant, the ion remaining in a space of the zeolite adsorption column and vacant holes of zeolite is removed by water without substantially containing the magnesium ion and/or the alkali-earth metal ion, and then the regeneration of zeolite is carried out by the alkali regenerant. This method is achieved by providing the concentration of ammonia nitrogen collected in the regenerated liquid to 2,000-10,000 ppm, further emitting ammonia contained in the regenerated liquid in a gas phase by steam or heated air using a solid alkali and/or a liquid alkali as an alkali of the regenerated liquid, and catalytically decomposing.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing ammonia nitrogen in the water to be treated, by each of which ammonia nitrogen can be removed selectively even from the water which is to be treated and contains not only a high-concentration alkali metal ion and/or a high-concentration alkaline-earth metal ion but also ammonia nitrogen. SOLUTION: When ammonia nitrogen is removed by using a metal chelate resin from the water which is to be treated and contains not only the alkali metal ion and/or the alkaline-earth metal ion but also ammonia nitrogen, if the pH of the water to be treated is adjusted adequately, only ammonia can be adsorbed selectively on the metal chelate resin without adsorbing the alkali metal ion and/or the alkaline-earth metal ion on the metal chelate resin. If the metal chelate resin on which only ammonia is adsorbed selectively is regenerated, the regenerated metal chelate resin can be utilized again for removing ammonia nitrogen in the water to be treated. The ammonia recovered in the recovered regenerating liquid is separated by adding an alkali to the regenerating liquid which is used for regenerating the metal chelate resin and recovered and stripping the alkali-added recovered regenerating liquid by steam or the like.

SOLUTION: The treatment method of the ammonia-containing waste water has an adsorbing process in which ammonia nitrogen in the waste water is adsorbed onto an adsorbent, an adsorbent regeneration process in which an ammonia component adsorbed onto the adsorbent is released in a regeneration liquid to regenerate the adsorbent, an elimination process in which ammonia is removed from used regeneration liquid containing a released ammonia component and an ammonia decomposing process in which removed ammonia is subjected to decomposition removal by an ammonia decomposition catalyst. Temperature of the used regeneration liquid in the elimination process is changed at at least two steps within a range of 40 to 80 °C and the temperature of the used regeneration liquid after the second step is made to be higher than temperature at the first step.
