Based on the working process of the traditional sewage treatment process, this paper aims at reform the defects of intelligent energy-saving. This system uses various sensors for on-line monitoring of wastewater parameters and uses the PLC to control the air blowers. Under the premise of guarantee the quality of water, this reform system can achieve the effect of energy conservation and emissions reduction.

According to pull-off test on reinforced concrete specimens with different corrosion rate, their failure patterns, relationship between bonding strength and slippage, variation laws of bonding strength and slippage are studied. The calculating formula of reduction coefficient of bonding strength and slip ratio is proposed. Based on these studies, constitutive model of bond-slip performance for corroded reinforced concrete is set up. It can be seen after verification and analysis that calculated results of this model agree well with trial values, which suggests that the bond-slip constitutive model of this paper is reliable and universal.
