Research on q-p-shaped elevated traffic system in wetland and forest parks

Ecological protection is the basis of the construction of wetland and forest parks and therefore any development and utilization should take it as the premise. The traffic system planning and positioning of wetland and forest parks should also follow this principle. The establishment of the q-p-shaped elevated traffic system equipped with ring elevated passage and local installation of ground and over-ground viewing platforms in whole park can achieve the diversion of commuter cars, bicycles and walking tourists which is conducive to solving the problems of patch fragmentation, human activities interference and single viewing form in wetland construction. In this paper, the ways of creating q-p-shaped elevated traffic system is introduced in detail and this study can provide reference for the planning and design of wetland and forest parks.

Analysis and Practice of Urban Wetland Construction Technology in Mining Subsidence Water Area

The mining of underground coal resources has a great impact on the ecological environment, especially in the high groundwater level area in the East, the mining subsidence has a more severe impact on the surface water, resulting in serious surface water, and the feasibility of restoring the original land function is poor. Based on the analysis of the characteristics of mining subsidence water, this paper puts forward the key technology of urban wetland construction, and analyzes it combined with engineering examples. The results show that: in the mining subsidence water area around the city, relying on the geographical advantages and abundant secondary wetland resources of coal mining subsidence, we can shape the regional tourism image, focus on the construction of Urban Wetland Park and ecological wetland, expand the urban service function of wetland in the aspects of leisure, tourism, education and tourism, as well as the rainwater storage and water purification function of wetland. This study provides a reference for the construction of similar mining cities.

Treatment of Sewage Water Through Constructed Wetland by Typha Latifolia

In India, about 38,255 million liters of sewage produced daily, out of which only 22% of the sewage is being treated. Wetland construction is a solution for the treatment of sewage water through the natural process of growing a plant. In this experimental setup, a wetland is constructed to investigate the performance of Typha latifolia when planted in sewage water and investigated for a period of 4 weeks. The constructed wetland (CW) setup was filled with sewage water with a hydraulic retention period of 7 days. Within the stipulated period of 4 weeks, the change in the characteristics of the sewage was tested for every 7 days. During the treatment period, the plant Typha latifolia has considerably reduced the chloride content by 29.69% and the BOD content by 20.51% in the sewage. Hence, it is inferred from the project that the plant species Typha latifolia has the ability to reduce the saline nature of the water. It is also noted that the efficiency of the treatment of sewage water by the plant species increases with the increase in the time period in which the CW system is maintained properly

The Effect in the Wastewater Treatment at Soybean Curd of Contact Time Modification of Artificial Wetland Using SSF by Using Schoenoplectus Corymbosus to Improve Water Quality

Soybean curd industrial is rapidly growing industry. Characteristic of effluent from soybean curd industrial may contains a lot of organic materials and suspended solids that give negative impact to water. One of the soybean curd industry pollution prevention is a modification of artificial wetlands with sub surface flow system using recirculation by S. corymbosus plant to reduce the value of BOD, TSS and nitrate in soybean curd wastewater. Early of research procedure is prepare wetland construction consist of 8 part box container with a capacity of 75 L, then filled in the basic medium gravel 5 cm, clay 10 cm, and then planted a S. corymbosus by 30 pieces/construction, then drained soybean curd waste that has been diluted through the recirculation pipe for 16 days in the land of green house plant physiology. The result of optimal decline BOD occured on day 12th ie 99,7, TSS decline value optimal ie 89,3% on day 12th, and declined of optimal nitrate on day 12th ie 89,7%. The decline value of BOD, TSS and nitrate until day 16th has been standart quality unless TSS according to Perda Jateng no.5 tahun 2012 and PP no.82 tahun 2001.

IDENTIFYING THE MOST SUITABLE AREAS FOR SURFACE FLOW WETLAND CONSTRUCTION IN LITHUANIA

GIS-based approach to find the suitable sites for surface flow constructed wetlands was employed for the Lithuanian river basins with low ecological status. According to the nature of the analysed criteria the flowchart consists of two phases. Criteria used include hydrographical network, soil properties, terrain features, land use, etc. Some of them have strictly defined values (constraints), and other ranges within certain limits (factors). Limited criteria were analysed using rejection principle and influencing factors using proximity analysis and overlay methods. Selecting the potential sites using standard GIS analysis tools there was estimated about 3286 sites for possible wetlands with the mean area of inflow basin about 4 km2 in the basins of water bodies at risk.

Comprehensive Benefits Analysis of the Artificial Ecological Wetland Construction in Tianjin Harbor Economic Area

Tianjin Harbor Economic Area is one of the important functional areas of Tianjin Binhai New Area. At present, its artificial wetland ecological construction has started running. In this paper, the comprehensive benefits of artificial ecological wetland are analyzed in terms of ecological, social, economic. Including the industrial park wastewater treatment, water conservation, increase biodiversity, promote regional low-carbon development, beautify the landscape of industrial parks, produce the best possible results of ecological publicity and education function and promote regional economic development. The analysis showed that the artificial ecological wetland in Tianjin Harbor Economic Area has broad application prospects for such large-scale industrial parks, and it can be used as demonstration to promote ecological industrial park construction.
