Abstract:
Phosphate in the effluents can be nearly eliminated by the combination of biological and chemical technology at present. However, the dissolved organic phosphorus (DOP) is hard to be removed as well as the residual DOP accounted for 52%-93.1% of the total phosphorus in the effluent. DOP not only provide phosphorus resource for algae but also hard to be removed by regular sewage treatment process, which will propose new challenges to reclaimed water treatment technology. To reveal the potential risk of DOP and promote the advanced removal of DOP, the occurrence and bioavailability of DOP in municipal wastewater treatment plant were comprehensively introduced in this paper, which provided theoretical basis for the scientific understanding of environmental effects of DOP. In addition, the research of enhanced DOP removal methods in the advanced treatment was also introduced to provide the idea and methods for upgrading and reconstruction of municipal wastewater treatment plants, as well as for the extremely low phosphorus discharge.
