Tóm tắt
Algae is a versatile resource with high value applied in various fields such as food, pharmaceuticals, cosmetics, biofuels, and wastewater treatment. In current wastewater treatment technology, the use of algae in the treatment process is being emphasized. This research aims to cultivate Chlorella Vulgaris algae in a suitable environment to help the algae adapt and grow rapidly during the wastewater treatment application. In two photobiological model systems HRAPs and PMBR combining microalgae Chlorella vulgaris and bacteria in shrimp aquaculture wastewater treatment showed that both model systems have good treatment efficiency. The removal efficiency of COD, nitrate N-NO3-, nitrite N-NO2-, ammonia N-NH4+, total nitrogen and P-PO43- reached 27.4%, 58.7%, -35%, 92.2%, 77% and 93.5, respectively % in HRAPs and 29.7%, 24.5%, 26%, 83.9%, 75% and 93.4% in PMBR model.
