Efficient Aeler Experimental Device

During the processing of active sludge method, the role of the aeration equipment during the processing process is to fully mix --r, active sludge and pollutants, so that the activated sludge is suspended, and the oxygen is transferred from the gas phase to the liquid phase, from liquid phase to activity to activity In the sludge, it is guaranteed that microorganisms have sufficient oxygen for material metabolism. Since the supply of oxygen is one of the m--n factors that ensure the normal development of the biochemical treatment process, engineering designers and operating managers often need to test the total transmission coefficient KLA of oxygen through experiments, and the oxygen supply capacity and power efficiency of the evaluation aeration equipment.

Through the hope of this experiment, the following goals are achieved:

1. Master the method of totaling the oxygen transfer coefficient and oxygen capacity of the aerated equipment;

2. Master the method of determining the correction coefficient A and B;

3. Understand the characteristics of various test methods and data finishing methods.

I. Overview

The company's first development, testing, and innovation of "Metal Technology" multimedia comprehensive experimental equipment, which integrates design, testing, and innovation, is suitable for courses such as "Metal Craft", "Basis of Mechanical Processing Crafts", and "Foundation for Machinery Manufacturing Technology". "Metal Crafts" is a basic course that must be studied by various majors in the University of Engineering in Higher Institute of Technology. It m--nly studies the manufacturing method of commonly used mechanical parts, that is, study parts from selecting materials, making roughs to comprehensive courses that are processed to finished products. This experimental device uses a variety of materials and media means, focusing on advanced technologies such as casting processing, forging processing, and metal cutting processing.

The experimental device adopts metal technology multimedia software. The multimedia courseware content produced is rich and colorful. It combines animation with two -dimensional and three -dimensional views. At the same time, it cooperates with the physical model. The effect is very good in the courseware. ; The experimental device uses 34 models and 34 description modules for students to use; the model and module board can be replaced with the content of the course.

2. Product characteristics

1. Metal craftsmanship teachings use a P4 computer host, one 17 -inch display, one mouse, and one keyboard.

2. Use Keyuan multimedia software interface to vividly demonstrate the structure and principles of various model structures (such as opening, closed molds, and components) with two/three -dimensional animations to enable students to realize the close combination of theory and reality.

3. Use the module board text chart to expl--n the file, guide students to independently analyze the structure and movement of the mold, and cultivate the ability to read the diagram and analyze.

4. Use the physical model to let students understand the composition and structural principles of casting tools in depth, increase student design and analysis courses, and cultivate students' innovative consciousness.

5. The experimental device uses 34 plastic organic models and 34 text chart boards, which introduces the functions and structures and functions of various molds.
