Release time：2024-06-26 19:00viewed：times
1. Experimental purpose: The clarification process
in water treatment usually includes coagulation, sedimentation and filtration, and the treatment objects are m*nly suspended matter and colloidal impurities in the water. After the raw water is added with drugs, the suspended matter and colloid in the water are coagulated to form large-particle floccules, and then separated by gravity through the sedimentation tank. The mechanical reaction inclined plate sedimentation tank is a water purification structure with two functions of coagulation and flocculation sedimentation. This model is an experimental device to show the internal structure of the flocculation reaction tank and the inclined plate sedimentation tank. It is hoped to achieve the following purposes:
1. Through direct observation of the plexiglass device, deepen the understanding of the various components;
2. Master the water flow direction and operation method of the mechanical reaction tank and the inclined plate sedimentation tank, and observe the conditions of floc formation and sedimentation.
