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.
該項目地處遵義縣南部，用地南北兩側(cè)緊鄰城市高速公路和鐵路沿線，用地內(nèi)部縱向貫穿場地規(guī)劃有城市主干道，交通十分便利，可達性良好。 桂花大道濕地公園以對濕地的設計和改造為主體，以旅游地產(chǎn)、配套建筑開發(fā)為依托，打造一系列濕地活動區(qū)域，并在此基礎上形成綜合性的市民活動集散地和城市地標新名片。 在公園的整體設計中，根據(jù)場地現(xiàn)狀因素和周邊用地等方面考慮，對山水格局進行整理和重塑，形成多樣的場地環(huán)境和游覽體驗。設計中注重發(fā)揮濕地的生態(tài)功能，并著重打造緩沖區(qū)域，保護當?shù)氐纳鷳B(tài)和物種平衡。
該項目與其他城市濕地公園最大的區(qū)別在于該項目的水源來自城市污水廠，如何將城市污水轉(zhuǎn)換為濕地凈水將成為本次設計的一大難點。我們將充分利用現(xiàn)有資源，分7個工藝流程，對污水進行凈化。 凈化工藝：污水首先經(jīng)過預處理，沉淀降解均化水質(zhì)水量；然后控制污水的均勻分布；出水進入濕地進行深度凈化，充分利用現(xiàn)狀梯田，布置人工濕地，使污水經(jīng)過表流濕地降低有機物濃度后，進行曝氣增氧，再進入潛流濕地脫氮除磷，后再經(jīng)過表流濕地進一步凈化。
