Using Scenedesmus quadricauda as the material and pot bottom wastewater from liquor-making as the culture medium to investigate the removal of total phosphorus,total nitrogen,and COD,and analyze the composition of S.quadricauda.Theresults show that the degradation rate of COD reaches 96.21％,total nitrogen decreases by 71.6％,and total phosphorus declines by 94.11％after 6 days of cultivation when pH is 6.O,pot bottom wastewater concentration is 5％,inoculation amount of S.quadricauda is 10％,and light intensity is 8 000 Lux.The contents of algal biomass,oil grease,and carbohydrates in the cultivation solution are all higher than those in the BG11 standard medium.This study can provide an experimental basis for the coupling of liquor-making wastewater treatment and microalgae cultivation.
