1. Experimental purpose:

1. Deepen the understanding of this process.

2. Master the performance of this process and test technology data, and use reliable data into production.

3. Make the operator improve theoretical and practical knowledge.

2. Experimental principle:

In front of this device is condensation and sand filtering.

There are a large amount of colloidal particles (also known as SS) in natural water and sewage, which is an important reason for turbidity to produce water. The colloid particles cannot be removed by natural precipitation.

The colloidal particles in the water are m--nly negative clay particles. The static exclusion force between the glue, the brown movement between the glue, and the hydration of the surface of the glue particle make the rubber particles have decentralized stability, and the electrostatic repulsion force is affected by the three. Adding concrete to the water can provide a large amount of positive ions, the diffusion of the compressed rubber ball, reducing the potential of the pupa, and the reduction of electrostatic exclusion. At this time, the Brown movement has changed from stability to unstable factor. It is also conducive to the adsorption condensation of rubber particles. In short, the process of throwing concrete until it forms a larger alum flower.

The lime sand filter layer in the sand filter column has a particle size of 0.3 to 2mm. It can leave alum flowers and impurities in water with small water pores with small filter pores. When the loss of the filtering head reaches ** allows the water head loss, the filter column needs to rush back. There is no fixed time for the backwing cycle, depending on the turbidity of the water.

The principle of integrated membranes is very simple. Most of them are filtered with polypropylene hollow fiber membrane and aromatic polyamide RO membrane. The better the water quality, the greater the electricity. The filtering of the membrane is American technology.

1. Product characteristics

1. Project practicalization: Taking typical actual parts as tr--ning objects;

2. Systematic functional: look at the tr--ning mode of trinity of parts, parts, and parts drawing, and parts drawing;

Views, three views, and multi -view parts from simple to complex tr--ning.

3. The popularization of students: small, combined, portable tr--ning devices, a group of two or three people, so that as much as possible students get

Full tr--ning opportunities;

4. Standardization of teaching: supporting and guidance books, teaching and learning are very convenient, and the teaching effect is significant;

5. Management convenience: parts, measurement tools and guidance books are placed in a refined box, which is very convenient to manage.
