- Abstract
In order to reveal the influence of reaction conditions on the phosphorus crystallization to recover phosphorus from wastewater with low P concentration, an alternate A/O biofiltration system for simulated domestic wastewater treatment was carried out and the effluent from anaerobic filter was considered as the reaction liquid for P crystallization, as well as the influences of phosphorus by beginning phosphorus concentration, pH, Mg/P molar ratio and reaction time on the MAP crystallization and P removal were test systemlly. The results showed that the pH is the main influence factor on the crystallization time, and the higher pH value, the shorter crystallization time. Under the condition of the low P concentration, the key factor of the crystallization phosphorus removal rate is the Mg/P. Improve the Mg/P molar ratio mghit increase the phosphorus removal rate greatly.In addation, when the Mg/P molar ratio is 1:1 and the reaction time is 10 minutes, the lowest crystallization concentration is 18mg/L.
