Drinking water treatment process training desk

Clear classes in water treatment usually include concrete, precipitation and filtration. The treatment objects are m--nly suspension and colloid impurities in water. After the raw water is added, the suspension of the water and the colloid in the water form a large particle flocculation, and then the gravity is separated by the sedimentation tank. The mechanical response sedimentation tank is a water purification structure with two functions: concrete and flocculation. This model is an experimental device that displays the internal structure of the flocculation reaction tank and the inclined sedimentation tank. Hope to achieve the following purpose:

1. Directly observe the organic glass device to deepen the understanding of each part of the composition;

2. Grasp the direction of water flow and operation and use of mechanical reaction tanks and sedimentation pools, and observe the condition of flocculation and precipitation.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 45 ℃

2. Treatment of water 200 L/h;
