The Removal Phosphorus Effect in different Sludge load conditions in an / OSBR
Based on An / OSBR we discussed on biological removal phosphorus system, in the reaction temperature at 15 ℃ and 25℃ under the conditions of COD load of sludge. Total phosphorus concentration of influent was be contented for 10 ±0.5mg / L, compared to anaerobic paragraph at the end of the water and TP concentration. The results showed that: ① two temperatures with the COD load of sludge was raised from the effect to reduce the concentration of TE when the sludge COD load≥ 0.46mgCOD/mgMLSS · d, the effluent TP concentration was lower than 1mg / L;② m reaction temperature of 25 ℃ and 15℃, the amount of anaerobic releasing paragraph and COD load of sludge are very good correlation, linear relationship between the two were: y = 0.72 +71.91 × ( 25 ℃), y = 2.81 +73.33 × (15℃);③ in the COD load of sludge under the same conditions, the removal rate in 15 ℃ is higher 5％ than the one in 25 ℃.
