The sustainable water quality improvement of the artificial lakes in Chung-Hwa University

---

Summary of results

    The water quality improvement system （see fig.1）that has been constructed，includes：1.pumping（1），2.Sedimentation tank，3.Ecological pond，4.Landscape & purification channel，5.Water wheel，6.Waterfall，7.Constructed wetland，8.Pumping（2），9.Pumping（3），10.Experimental purification channel，and 11.Wind-generating electricity system. The results of this project are summarized as following：

A . Creating a sustainable purification system：

    The system which applies the purification channel，ecological pond，and constructed wetland to improve the water quality of two artificial lakes on campus；and applies the Wind-generating electricity as power for the sustainable water-circulation .

B . Using Wind-energy：

    The wind-energy supply which is abundant in Hsin-Chu area，specially the north-eastern wind occurring from March to October，is utilized to generate the electricity for the pumping needs in this project .

C . Making good use of natural purification mechanism：

    The constructed facilities（EX：purification Channel，ecological pond，waterfall，and constructed wetland）are designed to make good use of natural purification mechanism and to avoid human interference.

D . Using the ecological engineering method：

    The facilities of the system are constructed by using the ecological engineering method .The porous space with landscape vegetation was created to provide the suitable habitats for biological species.

E . Editing education material：

    The education material of “Ecological Engineering of Wetland” was edited for this project to serve as educational purpose .
