Thread Content
This post was last edited by “Back to Cambridge” on September 27, 2016, at 14:38. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity to help everyone reinforce their basic knowledge in chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage continued participation from everyone this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What is the role of coagulation treatment in water supply treatment? Answer: The function of coagulation treatment is to cause the small suspended particles and colloidal impurities in water to aggregate into larger particles, which then settle and can be removed.
Function: The purpose of coagulation treatment is to cause the small suspended particles and colloidal impurities in water to aggregate into larger particles, which then settle and can be removed.

It enables rapid separation of sludge from water, reduces the moisture content of the sludge, and thus lowers energy consumption in the subsequent drying process.

Mine water containing trace elements or harmful elements mainly refers to fluoride-containing mine water, mine water containing trace toxic and harmful elements, and mine water containing radioactive elements. The discharge volume of such mine water is not large, but if left untreated, the toxic and harmful substances in the mine water will accumulate and concentrate in the water bodies to which it is discharged, causing environmental pollution. The typical treatment method involves removing the suspended solids from the mine water, and then using appropriate specialized coagulation and adsorption agents to eliminate the various pollutants present in it. Clean mine water is unpolluted, clean groundwater that meets the standards for drinking water and can be used directly. Currently, improvements in mine wastewater treatment processes focus primarily on the development of efficient treatment chemicals. Furthermore, some scholars believe that it is possible to emphasize the role of coagulants in wastewater treatment. Inorganic coagulants are added to the aeration grit chamber, causing the suspended and colloidal substances in the wastewater to become destabilized and aggregate as a result of interaction with the coagulants. Organic polymer flocculants are then added in the subsequent sedimentation tank to improve the efficiency of coagulation and removal, thereby achieving good water quality in the effluent. This method has been applied in urban sewage and water treatment plants, achieving good results.
During the mixed treatment, small and medium-sized suspended particles as well as colloids are aggregated into larger particles that settle and are removed.
