Anaerobic-aerobic Activated Sludge Treatment followed by Phytoremediation to Dairy Effluent

摘要

India is a developing country and hence more attention paid to improve the quality and quantity of milk and milk products than that of the effluent treatment. Direct or indirect disposal of dairy effluents into the natural water bodies generates Eutrophication, serious health effects on aquatic animals and human health also. The present study is carried out to find an efficient treatment using anaerobic aerobic activated sludge treatment followed by phytoremediation for the Dairy effluent. The microbes of endogenous origin are used to treat the Dairy effluent and Phytoremediation by the aquatic macrophyte Eichhornia crassipesis done. The results of current study illustrated that BOD, COD, TS, Sulphate, Chloride and BOD: COD ratio are 86%, 87%, 96%, 75%, 89% and 0.99 : 1 respectively which very higher percentage of reduction and covers the safe disposal Standers for Dairy effluent.
