Abstract
Because of the rapid development in Taipei city, the population in Xinzhuang city and Shanchuang city increases greatly. Residents have strong demands of extending the green spaces; therefore, the government of Taipei County proceeds the project of beautification and revegetation for the waterfronts which provide people places for rest and recreation. Erchuang floodway is one of the functional and modern recreational areas which is from a muddy place into a beautiful wonderland. It is also a great policy cooperated between the authority and administration. The Breeze canal in Taiwan is an international standard rowing place which has a considerable potential to be developed as an athletic and leisure area. It provides not only a place for rowing practice and competition, but also a place for public recreation. However, the water quality in this canal is unstable and is affecting users’ hygienic safety. In order to provide a safe environment, it is necessary to understand the possible reasons of influencing and changing the water and to apply natural purification, and then to improve the water quality and whole environment by applying the natural purification. The natural purification includes natural treatment system, contact bed treatment and wetland. However, contact bed treatment is the most appropriate method of dealing with the water quality. Thus, this study focuses on processing the method of contact bed treatment in the Breeze canal and the relative planning and applications of the study. This study uses testing method for water quality to analyse the water quality and to set the goal of the purification; afterwards it collects the information of the real environment and publics’ opinions of speciality of the environment. Moreover, it also takes domestic and foreign cases of using contact bed treatment as a consideration of real environment planning and the water quality improvement. Eventually it presents the analysis of the advantages and disadvantages of using contact bed treatment by SWOT, and draw up the applied policy and the initial planning and the suggestion. This study on real environment planning suggests that the water-purifying device designed based on contact bed treatment should be sited on a slope along the canal to achieve energy saving and device simplification. However, the current water quality test result indicates that the numbers of BOD,SS, and Escherichia coli fail to meet the standard of second water quality mode. The expected goal of this water quality improvement project will refer to other relevant cases intending to satisfy the standard of second water quality mode. The analysis of this research and its related practice aim to improve the water quality, identify the source of and reduce the water pollution, promote Eco-education, and strengthen the multiple utilization of park. The efforts of this research will provide the reference to further improve the water quality and the environment of the park.
