摘要

Transformation of phosphorus forms in the construction process of biological phosphate reduction system was discussed in treating saline and high-phosphorus pickled mustard tuber wastewater to resolve problems encountered with present phosphorus removal technology. A phosphate reduction system under hypersaline condition (salinity, 7%, measured by NaCl) was successfully constructed, when the reactor was started with 3%-salinity wastewater and the salinity was increased through two stages, at influent organic loading 0.45kgCOD/(m3Ȃ2;d), phosphorus loading 5.0gPO43--P/(m3Ȃ2;d), DO 6mg/L, 30¿ and without sludge discharge. Phosphorus balance and transformation of phosphorus forms in sludge was studied on 26 running cycles of this phosphorus reduction system. Results showed that averagely 41.8mg/L of external phosphorus got lost per day, and that 155mg of internal phosphorus in sludge get lost through the path of phosphorus forms transformation and phosphate reduction, which accounted for 14.2% of the external phosphorus loss and 12.5% of the total phosphorus loss, respectively. The transformation path of phosphorus forms in sludge is Org-Pș2;NaOH85-Pș2;HCl-Pș2;NaOH-Pș2;BD-Pș2;H2O-P.
