Phosphorus Recovery by Struvite Crystallization from ...

4/4/2016, · In China, the intensive livestock farming produces massive livestock ,wastewater, with high concentration of phosphorus. Discharge of these compounds to surface water not only causes water eutrophication but also wastes phosphorus resources for plant growth. Therefore, it’s necessary combining the removal of phosphorus from livestock ,wastewater, with its recovery and reuse as fertilizer.

A combination of hydrothermal treatment and FeSO4/Ca(ClO)2 oxidation was developed in our previous work and was proved to be significantly useful for improving the sludge dewaterability. The dewatering mechanism of the sludge after the combined treatment of hydrothermal treatment and FeSO4·7H2O/Ca(ClO)2 was obtained for the first time based on the moisture distribution analysis. …

In nuclear ,wastewater,, the presence ,of alkali, and alkaline earth metal ions (e.g. Li +, Na +, K +, Mg 2+ and Ca 2+) affects the absorption of Cs +. Among them, K + has the greatest effect on the adsorption of Cs + since there is a close radius between K + and Cs + . 35 Therefore, in this experiment, K + was selected as the competitive ion of Cs + to explore the adsorption selectivity of CMC–AMP.
