Abstract:
Chlorella pyrenoidosa was coimmobilized with activated sludge to produce algae-bacteria beads for sewage treatment. Hydrolysis/acidogenesis pretreatment could improve the symbiotic microenvironment of coimmobilized Chlorella pyrenoidosa and activated sludge, and as a result, promote the removal of nutrients (COD(cr), inorganic nitrogen and inorganic phosphorus) in the sewage. A photo-bioreactor combining hydrolysis/acidogenesis pretreatment and coimmobilized technique was designed to treat sewage continuously. The results show that, the removal efficiencies of COD(cr), NH4(+)-N and TP reached steady state after 4-days of experiment. The removal efficiencies of COD(cr), NH4(+)-N and TP were 59.6%, 59.0% and 60.3% respectively.
