摘要: Abstract The influence of biotic (algal inoculum concentration) and abiotic factors (illumination cycle, mixing velocity nutrient strength) on the treatment efficiency, biomass generation settleability were investigated with selected mixed algal culture. Dark condition led to poor removal efficiency. No significant difference in N, P between continuous alternating illumination was observed, but a higher capability for obtained. Different similar phosphorus efficiencies (above 98%) different retention times. reactor 300 rpm had best N capability. For low strength wastewater, rates 5.4 ± 0.2, 9.1 ± 0.3 10.8 ± 0.3 mg/l/d 0.57 ± 0.03, 0.56 ± 0.03 0.72 ± 0.05 mg/l/d reactors concentration 0.2, 0.5 0.8 g/l, respectively. Low efficiency obtained high wastewater.
