Abstract

Phosphorus resources are non-renewable and difficult to replace natural resources, but also play an important role in the development of strategic resources in the world. However, this element which was once considered to be extremely rich in nature will become a scarce resource in the near future.This experiment was carried out by the laboratory to provide Phosphorus accumulating organism strains, identified as the fungus penicillium sp. The results showed : (1) the biomass of penicillium sp. and its phosphorus uptake increased with the prolongation of culture time in the simulated sewage . The dry weight and phosphorus uptake were stable at the 8th day, which were 0.91g and 16.89 mg-L-1, respectively. The phosphorus uptake rate reached 16.89mg-L-1 and the rate of phosphorus accumulation was 84%;(2) the effect of different forms of inorganic phosphorus on the strain was different. Among them, the effect of calcium and phosphorus was the highest, and the dry weight of strain was reached 14.3g-L-1 after 10 days , and the amount of phosphorus reached 88.98mg-L-1.In addition, the results also showed that the use capacity of strain JB201015 for different forms of inorganic phosphorus was related to the amount of phosphorus and the strain of Penicillium sp.JB201015 could grow rapidly not only in simulated waste water, but also showed good ability of Phosphorus accumulating organism, which indicated that the strain had good application prospect in phosphorus recovery of waste water.
