2. Experimental principle:

High -concentration organic wastewater is generally treated with lift -type anaerobic sludge reactors. Referred to as UASB bioreactor. There is a carrier inside this reactor, which is a suspended growth type of anaerobic digestion. The sludge layer with a high sludge concentration at the bottom of the reactor is called a sludge bed, and the sludge layer with a slightly lower sludge concentration in the sludge bed is called a sludge floating layer. The sludge bed and the sludge suspension layer are collectively referred to as the reaction area.

In the state of anaerobic, the biogas produced by microorganisms has a strong stirring during the rise process, which is conducive to the formation and m--ntenance of granular sludge. The wastewater enters the bottom of the reactor uniformly, and the sewage is upward through the sludge bed cont--ning granular sludge or flocculent sludge, and anaerobic reactions occur during contact with the sludge particles. Three -phase separator. The sludge particles of biogas balp and biogas 0 foam rose to the top of the reactor to the bottom of the gas reflective plate. The biogas bolt is collected to the top of the reactor to warm the water tank, and it is discharged after being measured by wet flow.

1. Function and characteristics:

The bolt group connects the experimental device to perform experiments such as bolt static stress, deformation, stiffness, axial load, pre -tightening tightening, and other experiments.

Special test analysis software can perform related detection of bolt static and dynamic, and can compare the measured and simulation curve, and the curve can be printed.

All tested elements adopt a full bridge test circuit, and each str--n testing structure is stable, repetitive, and high accuracy.

A single -phase AC motor (220V power supply) is used to start the motor for a dynamic bolt experiment.

Dedicated test analysis software has multimedia teaching functions. Students can expl--n the experiments by experiments in the software and edit the test report through the software.
