| titleOfInvention | Composite dephosphorizing agent for treating phosphorus-containing wastewater and application method thereof |
| abstract | The invention relates to a composite dephosphorizing agent for treating phosphorus-containing wastewater and an application method thereof. The composite dephosphorizing agent comprises the following components in parts by weight: 35-80 parts of base, 15-50 parts of iron salt component, 2-15 parts of sodium salt component, and oxidizer. The application method of the composite dephosphorizing agent comprises the following steps: compounding the base, iron salt component and sodium salt component, diluting with water to obtain a 1-20 wt% water solution, adding the oxidizer into the water solution, and finally, adding the water solution into the phosphorus-containing wastewater, wherein the volume ratio of the water solution to the phosphorus-containing wastewater is 1:(100-1000). The composite dephosphorizing agent has the advantage of simple and accessible raw materials, is convenient to use, and can effectively perform dephosphorization operation on medium/high-concentration phosphorus-containing wastewater. The phosphorus content in the effluent water can reach 0.5 ppm below, and the phosphorus removal rate in the medium/high-concentration wastewater can reach 90-99% above. The composite dephosphorizing agent can be used for treating printing, pesticide and other types of phosphorus-containing wastewater. |
