lgae via a concentration gradient, can adapt to domesticate with high salt wastewater. Wastewater without antiseptic processing, using microorganism and algae between symbiotic algae bacteria - any role construction system. When wastewater dilution ratio was 0.95 light for 1200Lux, incubation temperature for 34 ℃ concentration of carbon dioxide is 6.3%, wastewater treatment, when wastewater best effect 30.03%, protein content COD reduce 10.15%, reducing salt content low 22.56%, pH value from 4.56 rise to 10.02. After incubation of wastewater discharge standard, still can not reach the algae liquid centrifugal separation, will not domesticated by inoculation to centrifugal fluid continue to cultivate, second training wastewater COD to 100mg/ml below, meets emission standard. Through cultivation condition optimizing, protein nuclear chlorella cells dry weight can achieve 1.25 g/L, fatty acids can achieve 44.36%, ? |
