Dvoretsky D., Dvoretsky S., Temnov M., Markin I., Fu P., 2017, The Technology of Pre-Purification Treatment of Municipal Wastewater Using Microalgae Chlorella Vulgaris, Chemical Engineering Transactions, 57, 49-54.
The possibility of integrating systems for wastewater treatment and production of raw materials for renewable sources of energy (lipids) and biodegradable polymers (lactic acid) has been studied. Municipal wastewater from sewage facilities was used as nutrient medium for the cultivation of microalgae strains of C. vulgaris IFR C-111 and C. vulgaris Beijer IPPAS C-2. Experimental research has shown that cultivation of vulgaris, strain IFR C-111 generates a biomass of cells with intracellular lipid content of 14 % (mass.). Cultivation of a strain of C. vulgaris Beijer IPPAS C-2 for 9 days allows to accumulate a biomass of cells with intracellular lipid content of 21% (mass.). Both strains succeeded in reducing the concentration of total nitrogen and phosphorus in wastewater by ˜50% over 4 days. It is established that the cultural liquid of microalgae can form the basis of the nutrient medium for the cultivation of bacteria Lactobacillus casei B-3241.
