The wastewater treatment is difficult belong to the complex composition, high concentration and high toxicity, low biodegradability of the pollution [2-3].The selection of adsorbing materials is the development trend of the phosphorus wastewater treatment.
Attached to the activated charcoal pore of chemical compounds such as organic matter, carbon dioxide, water vapor overcome the van der Waals force began stripping, with microwave energy concentration, part attached to the material on the surface of the activated carbon decomposition release gas carbonization appears, and the interior of the activated carbon pore widening, especially the excessive pores, enables the activated carbon to remove more contaminants.

The material of tower and web member is 20# seamless steel tubes.
There is 45°slip line in the web member which formed by the relative slippage of internal structure in material.
The force-deformation curve is nonlinear at 280KN, which means the material become into the nonlinear stage.

The problem relating historical deformation, such as viscoelastic material model and the time effect of inertia (dynamic problems), must use incremental method.
In the loading process, the failure meeting any criteria set, will cause the material damage.
