| titleOfInvention | Preparation method of precipitator for dephosphorization with ferric salt |
| abstract | The invention discloses a preparation method of a precipitator for dephosphorization with ferric salt. The preparation method comprises the following steps: 1) placing 1.5-3.0g agar in 50ml water, heating to dissolve the agar, and maintaining the melting state to obtain an agar solution for later use; 2) placing 5-20g FeSO4 in 50ml water so that FeSO4 is completely dissolved under the stirring condition to obtain a FeSO4 solution for later use; and 3) evenly mixing the agar solution obtained in the step 1) with the FeSO4 solution obtained in the step 2) while hot to obtain a FeSO4 agar solution, and standing until solidification. The precipitator prepared by the preparation method has the high efficiency of dephosphorization with ferric acid and also has the porosity, plasticity and degradability of the agar. By using the agar as a carrier, partial high-concentration ferric salt can be formed inside the agar to improve the wastewater dephosphorization efficiency; the precipitator can be prepared into granulate shape, cake shape and columnar shape with wide application range; the wastewater before and after treatment is maintained at the solid state for convenient separation and transportation; and the agar is biodegradable and harmless to the environment; and besides, iron phosphate/ferrous phosphate with higher purity can be obtained. |
