PROCESS FOR SEWAGE WATER PURIFICATION

摘要

Process and apparatus to remove colloids and nitrogen compounds from cont aminated water by coagulating the colloids and separating them from the wate r. The water is then continuously oxidized with chlorine electrolytically to destroy the nitrogen compounds. The apparatus for the purification of conta minated waste, comprises (a) an electrolytic cell (2) (b) an entry port belo w the electrolytic cell (1), (c) an upper section above the electrolytic cel l including an air sparger (7) and an outlet (5) (d) a closed draining space adjacent to the upper section comprising means for separating water and imp urities (9) and (e) a re-circulating pump (11) connecting the outlet to the entry port of the electrolytic cell, wherein the electrolytic cell comprises electrodes connected in series.
