Treatment and reuse of beer wastewater using the system of phytosysthetic bacteria and spirulina maxima
光合细菌和螺旋藻对啤酒废水的净化与利用研究

A study on the install of phytosysthetic bacteria (PSB) and Spirulina maxima (SM) for beer wastewater treatment and reuse was carried out.The beer wastewater was treated with PSB to decompose organic matter.Chitin was then added for PSB precipitating.Finally,SM was added to remove organic matter and reuse nitrogen and phosphorus.The effects of pH,DO,illumination,the density of PSB and SM etc.on the removal of COD by PSB and on the growth of SM were discussed.The results of a dynamic model experiment showed that the system of PSB SM not only have a high removal efficiency for COD and NH4+-N (100%),but can also yield a large amount of SM (78.1mg (dry weight)/(L·d)) and protein in SM (49.3mg/100g (dry weight)).
