The phosphorus removal capacity and treatment efficiency of polymerized iron sulfate phosphate remover were tested
II. Experimental Methods:
1. Water source: take the biochemical terminal water of domestic sewage treatment plant (the total phosphorus content of supernatant is 1.6 mg/L after natural settlement)
2. Prepare phosphorus remover solution with quality fraction of 1%. Preparation steps: Take 10g of phosphorus remover to dissolve in 1000 ml volumetric bottle.
3. Four groups of 1000ml of biochemical end water were added with 5.0ml, 10.0ml, 15.0ml, 20.0ml and 1% polymer iron sulfate phosphate remover solution, and the corresponding concentration was 5ppm, 10ppm, 15ppm and 20ppm to measure the total phosphorus value, and compared with the total phosphorus value of the supernatant after natural settlement of the water from the biochemical end without drugs.

IV. Test Conclusion:
According to the total phosphorus of 1.6 mg/L before drug injection, the phosphorus removal rate after drug addition is:
At the added concentration of 5ppm, the phosphorus removal rate was 70.625%
At the added concentration of 10ppm, the phosphorus removal rate was 85.625%
At the added concentration of 15ppm, the phosphorus removal rate was 91.25%
When the concentration of 20ppm was 95%
