Training device of biological turntable principles

Biological turntable is a device that uses biofilm to purify sewage. It is a biological treatment technology with good purification effect and low energy consumption. In addition to the biological turntable in the biological turntable treatment system, it also needs to include the first sedimentation tank and the secondary sedimentation tank. This model is only a biological turntable, and does not include the secondary sedimentation tank of separation and falling biofilm. The m--n components are rotor shafts, turntables, wastewater treatment grooves and drivers. This experimental device is a demonstration device in the internal structure of the biological turntable, and it is also an experimental device for the sewage to treat sewage. Through experiments, I hope to achieve the following purpose:

1. Through direct observation of organic glass devices, deepen the understanding of its structure, and understand the names and functions of each part;

2. Through the dynamic operation of the experimental device, master the technique of processing sewage in biological turntable methods, and understand the characteristics of the method.

Overview:

Smart buildings and electrical installation tr--ning devices are two -story building platforms composed of aluminum alloy skeleton and activity mesh boards. Event and surrounding buildings. Building experimental tr--ning device rooms provide the installation range of the front and back walls and top walls, and also provide the door of the room. You can install electrical plug -in locks, electromagnetic locks, door magnetism, and closed doors. Realize the installation and operation of various types of systems in intelligent buildings, such as "intercom and indoor security systems" and "closed -circuit TV monitoring and peripheral security systems".

The "building electrical installation tr--ning system" is a two -story simulation building building built by 1 aluminum alloy stent and 17 mesh boards. , Two -floor channels, two -story channel windows, second -floor residents, second -floor resident door, second -floor resident windows, vertical shafts and surroundings of buildings. The room provides the installation range of the front and back walls and the top wall, which can be installed on it with various building intelligent devices. At the same time, the door and windows of the room can be installed. Eliminating devices can be installed and operated by various systems of intelligent buildings, such as "intercom and indoor security systems" and "closed -circuit TV monitoring and peripheral security systems". Compared with a single -layer simulation floor, the two -floor simulation floor needs to consider the multi -floor structural relationship of smart buildings. In addition to cultivating students' engineering construction capabilities, it can also cultivate their engineering design capabilities and engineering innovation capabilities, which is in line with the practice of colleges and universities in colleges and universities. Teaching needs.

The installation method of the device is consistent with the actual engineering. With the cooperation of self -attack screws and mesh plates with expansion fixed parts, students can complete the fixation of the device on one side of the simulation wall; The front of the hole plate) may be through the dark line of the rings (the opposite side of the mesh board).

Aluminum alloy bracket size: 3010mm × 1305mm × 2550mm (long × width × height)

Mecar size: 750mm × 600mm × 35mm (length × width × height)

Building building and smart building electrical installation virtual simulation software

Based on the UNITY3D design, users choose different interactive interface size based on the computer configuration. The software in the software can be rotated, magnified, reduced, and translated at 360 °. There are small assistant tips for software use, the content is as follows:
