Method for removal of ammonia from sewage and the stripping tower for removal of ammonia from sewage

摘要

the object of the application is the removal of ammonia from waste water comprising way: initial ph increasing sewage contaminated (sca); introduction of contaminated water stream (sca) to the upper part of the tank strippingowego (21) columns strippingowej (2) on the bed rozdeszczaj u0105cym (211); the introduction of the working steam (rag) in the lower part of the tank strippingowego (21) columnsstrippingowej (2); a working stream [horn honks] water vapour (rag) through a rozdeszczaju0105ce (211) and the opposite of him falling stream of an effluent (sca); discharge stream of working steam (rag) with ammonia zaabsorbowanym top factors in the strippingowego (21) columns strippingowej (2); and draining purified water stream (swhat) from the lower part of the tank strippingowego (21) columns strippingowej (2); which is characterized by the fact that in the first stage, the ph value of sewage contaminated increases to the range from ph 8.0 to 9.5, preferably from ph 8.5 to 9.0, advantageously using naoh as a corrective substance; a working steam (rag) generates by boiling wastewater treated (sco) collected in the supply tank (22), which is directly connected with the upper and lower inlet tank strippingowego (211) columns y strippingowej (2),the steam is achieved by heating the wastewater treated (sco) after the strippingowym tank supply (22) with the original water vapour (ppw) introduced by bubbling below the wastewater treated (sco).the introduction of working steam tank strippingowego (21) follows directly from the supply reservoir (22) through a lower inlet strippingowego tank (21). the object of the application is also a column for removing ammonia from wastewater voltammetry.
