Take the mining wastewater from one factory as simulation wastewater. The contrast experiment of flocculating effect between the two home-made products with the intrinsic viscosity of 4.6dL/g and 3.8dL/g respectively and the manufacturer sample is made, and the visible uv spectrophotometer is utilized to measure its supernatant transmittance. The results showed that the home-made one with the intrinsic viscosity of 4.6dL/g has a effect close to the sample, which can satisfy the demand of the factory.
