On high alkaline sulfide-containing wastewater treatment
Summary
One of the main problems experienced during tannery wastewater transportation and treatment is hydrogen sulfide release that causes pipeline corrosion, gas contamination of premises and wastewater treatment facilities territory. The methods of sulfide-containing wastewater treatment have been well investigated; however, the reason of hydrogen sulfide release is still urgent and needs explanation. Theoretic and experimental studies carried out at the Moscow State University of Civil Engineering allowed explaining the reasons of hydrogen sulfide release from high alkaline solutions. Experimental studies with standardized test solutions of sodium sulfide showed that their alkalization inhibited hydrogen sulfide release, however required large amounts of alkaline agent and could be hardly adopted for practical use.
