| The immediate discharge of industrial wastewater pollutes the received water body leading to the serious waste of water resources. To lessen the pollution of the Yellow River with industrial waste from Bao Gang & higher the recycling rate of industrial water, it is high time that a plant dealing with industrial wastewater be set up, So a research, to which this thesis belongs, is done to provide accurate process and technical factors. Two steps are included; one is the static experiment in the laboratory, the other the dynamic experiment on the spot.The thesis is based on the dynamics of coagulation, with the section of coagulation treatment as the subject, using chemical coagulation method. It systemically analyses the component of wastewater and its pollution index, and discusses the factors, which affect the flocculation. The plan for dealing with wastewater, experimenting process, and general results, especially the application of coagulation treatment is stated in it.The type, amounts, blending and reaction time of coagulator and flocculent and the GT number in the coagulation treatment are determined by the experiment in the laboratory, while the experiment on the spot tests the technical factors emerging in the static experiment. At the same time, the effects of coagulation, including the removal rate of turbidity, COD, SS with different coagulator & different dosage amount, are tested. They provide the optimum condition & technical indicators for the building of the plant.The result shows that using PFS as the coagulator, 30mg/l of it is needed with theblending time 2 minutes, using PAM as the flocculent, 0.2mg/l of it is needed with the blending time 12 minutes, and the GT member 24000. Under this condition, the average removal rates of SS, turbidity, COD and oil are respectively 78.92%, 91.10%, 54.9% and 37.3%, getting to the standard of filtration section.
