In this paper, Iron-Oxide-Coated-Zeolite has been prepared by using natural zeolite and ferric nitrate. The absorbing effect of IOCZ on phosphorus is also investigated, including the filler height, the flow rate and initial phosphorus concentration on breakthrough curve were studied. The results show that IOCZ as an adsorbent can effectively remove the phosphorus from the wastewater. When the filler height and the initial phosphorus concentration increased, the adsorption effect increased and the breakthrough time reduced. The best filler height is 30cm. The higher the initial phosphorus concentration is, the less the processing water is. Column experiment was used for advanced treatment and it can process substantial wastewater, and then makes the effluent phosphorus concentration meet the national emission standards. When the regenerated solution was trickled into the solution about 5min, almost all of the phosphorus separated from the IOCZ.

Gray cast iron specimen was heated to a fixed temperature with high frequency induction heating equipment, then was cooled to room temperature by spraying water to the heated surface. This process was repeated until a crack whose length exceeds 3mm appeared. Transient cyclic heat transfer and stress-strain FEA analysis was conducted to obtain specimen’s stress-strain state, then different LCF life prediction methods based on strain and energy were presented and contrasted, and results showed modified dissipated energy method with maximal hydrostatic pressure was more accurate than other methods. With the help of modified dissipated energy method, the relationship between thermal shock life, highest cooling temperature and cooling speed was studied, and the effect law of highest cooling temperature and cooling heat transfer coefficient on life was obtained.
