This test adopts conical flask batch test. In order to ensure the rational use of the new manganese sand composite filter material (MTZ) and achieve adsorption saturation, it is necessary to determine the dosage of the new manganese sand composite filter material (MTZ). Take 7 250ml conical flasks and put 0.05g, 0.08g, 0.10g, 0.15g, 0.20g, 0.25g, 0.3g MTZ and 100ml waste liquid with iron ion concentration of 5mg/l and manganese ion concentration of 2mg/l into them. Shake them at 25 ℃ for 24h in a constant temperature water bath oscillator. Measure the iron and manganese ion concentration in the filtrate, calculate the iron and manganese ion removal rate, and determine the optimal dosage of MTZ.</p>",
