ANAEROBIC REMOVAL OF SULPHUR COMPOUNDS FROM WASTE WATER |
摘要 |
<p>Method for anaerobic removal of a sulphur compound from waste water containing said compound, comprising the steps of: 1) feeding the waste water to an anaerobic digestion system; 2) converting the sulphur compound in the digestion system to a sulphide; 3) circulating an effluent containing the sulphide from the digestion system in a by-pass channel, said channel comprising a stripper system for stripping the sulphide from the effluent; 4) removing the sulphide from the effluent by contacting with a transporting gas in the stripper system; and 5) converting the sulphide to sulpher; wherein 6) the sulphide is absorbed from the transporting gas in an absorber system by an absorbing liquid, which absorbing liquid is passed in a closed loop through the absorber system and a regenerator system, and comprises a regenerable redox liquor, which redox liquor has a pH-value in the range 4 to 7, preferably about 6.5.</p> |
