The project is in the south of Zunyi County, the north and south sides of the land is close to the highway and railway. There is a city main road passing through the site. The site has a convenient traffic condition and good accessibility.Long Keng Wetland Park is mainly aimed at the design and renovation, basing on the development of tourism real estate and supporting facilities. We would like to create a series of activity space. On the foundation of the above aspects, the site will be a comprehensive public activity space and the new landmark of the city.In the overall design of the park, according to the existing factors and the landuse of the surroundings, we collate and reconstruct the landscape, to form a various site environment and tourist experience. The design pay attention to the ecological function and the construction of buffer zones, and the ecological balance and local species.
Compared to wetland parks of the other cities, the difference of this project is that the water source of it comes from the city sewage plant, how to change the city sewage into the wetland water will become a major difficulty of this design. We will make full use of the existing resources. And we use 7 process to purify the sewage. Sewage purification process: firstly, the sewage need to be preprocessed and by the process of sediment and degradation to change the quality and quantity of the water. Then, we control the average distribution of the sewage. The water flows to the wetland to be cleaned further.We make full advantage of the existing terraced fields to arrange artificial wetlands. The organic concentration of the sewage is lowed by the surface flow wetland, then take the sewage to aeration. After that, the sewage flows into the subsurface flow wetland for phosphorus removal, and finally be purified by the surface flow wetland again.
