MBR membrane filtering training table

Through experiment hopes to achieve the following purpose:

1. Understand the basic operation process of the treatment of multi -functional sewage treatment of unnoram -inferior, good oxygen, and "MBR" membrane.

2. Deepen the understanding and basic principles of this process.

3. Master the technical parameters and practical knowledge of this process.

4. The A/O method -based processing process is adopted in front of this device. The subsequent film filtering method can be used.

The sewage is removed into the water tank after removing large particles and fibrous impurities. Then enter the anaerobic tank through the pump metering tank for acidification and hydrolysis. At this stage, the average quality of the sewage is regulated, and the characteristics of the large -molecular structure that is not easy to degrade with the characteristics of short -generation, poor activity, and prone to breeding and growth are used to hydrolyze them into small molecules and soluble compounds. Nitrification, *** pollution of nitrogen removal. The aeration of the sewage flowing into the puzzle with fillers is exposed to the oxidation pool.

I. Overview:

Multi-functional and practical drawing desk fixed drawing table bracket adopts steel frame structure, the desktop panel uses Northeast high-quality thick beylum material No. 1 drawing board, and can adjust the inclination angle of 0 ° -85 °. The lower part of the desktop has a storage partition. Schoolbags, stationery and drawings are solid and durable. It is suitable for mechanical drawing and drawing and p--nting. A multi -functional and lifting drawing drawing table of practicality and economy in colleges and universities has strong compatibility of various industries and courses. And popularity.

2. M--n features:

1. This drawing table is a domestic ** product. The difference between any domestic drawing table is that the unilateral dual support structure is used to greatly enhance the stability and firmness of the table.

2. The industrial desktop is equipped with gray -white melamine surface fireproof board, PVC high temperature edge. The inclination angle uses the spring hinge to regulate the inclination angle without stepless, and the angle range is 0-85 °. At the same time, it has a locking device to ensure that the inclined angle does not slide.

3. The desktop height adopts a suitable height that meets the principles of ergonomics: 800mm, the foot column uses 30 × 30 × 650 cubic steel, the ground -to -ground tube uses 50 × 30 × 530mm square steel, and the frame frame is welded by 20 × 20mm square steel.

4. All steel pipes are made of high -quality steel, which are washed, phosphorified, anti -static spraying, and high temperature solidification. All iron links are protected by carbon dioxide gas, and the solder joints are beautiful and firm.

5. Machinery tr--ning Safety Education Virtual Simulation Software: This software is developed based on Unity3D, which can be arranged to the cloud server side, or it can be used in the local environment. The software can be used in the form of 3D roaming. There are basic assessment of mechanical safety distance experiments, mechanical safety protection device experiments, mechanical safety protection design, and during the experiment, the three -dimensional roaming screen uses arrows and footprint patterns to move to the experimental location. Reminder of a three -dimensional robot dialog box.

A. Mechanical safety distance experiment content includes a safe distance experiment to prevent the upper and lower limbs from touching the dangerous area (the height and opening of the two fences in the inside). After choosing to enter, the GB23821-2009 "Mechanical Security to prevent the upper and lower limbs from touching the dangerous area of the dangerous area. "Safety distance" requires that the error demonstration: After the experimental process is harmed by the working radius of the human body entering the mechanical object, the blood color picture and voice reminder receive mechanical damage, return to the original position and perform the next experiment. The final step is the correct practice. Essence
