固定化菌藻系统对污水处理厂出水的深度处理
Advanced treatment of effluent from a wastewater treatment plant by embedded immobilized bacteria and algae system
摘要
Abstract
Coimmobilized activated sludge and Chlorella vulgaris with sodium alginate as entrapping agent were made into beads to treat effluent from a wastewater treatment plant in the fluidized bed reactor and the removal efficiencies of ammonia nitrogen,TP and COD were studied.The experiment indicates that under the conditions of natural temperature,HRT,DO,pH were 12 hours,3 mg/L,6.2 to 8.0,respectively,the embedded immobilized bacteria-algae has strong ability to remove ammonia nitrogen,TP and COD,and the removal rates are more than 60%,60% and 30%,respectively.The effluent concentrations of ammonia nitrogen,TP and COD basically maintain less than 8,0.5 and 40 mg/L,respectively,meeting the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002).This study shows that coimmobilization of activated sludge and Chlorella vulgaris in small beads has the potential application prospect in the advanced treatment of effluent from wastewater treatment plants.关键词
