A New Type Of Composite Flow Constructed Wetlands In Rural Liferesearch And Application In Wastewater Treatmente

At present, the situation of rural water environment is not optimistic, the overall water quality contamination is very serious; the same time, rural sewage treatment technology is not perfect, and serious deterioration of the water situation. The main topic will be a variety of single wetland in series or in parallel into a composite stream, pre-integrated equipment, combined Hongxia Jin Town Village, Zhang She Zhang in the village, narrow harbor village three, three sewage treatment Mencius Creek Demonstration Project indicators of process water testing, analysis and comparison for the selected process; while the design transformation wetland modular production, which combines with the integration of equipment, play better treatment effect, reaching directly into the tail water standard rivers.Research methods used in this study is mainly the combination of theory and practical application of the theory with the actual engineering design data, operating data, the two are confirmed. Referring to the design specification parameters, the composite stream wetland theoretical design applications in the experiment, take a series of monitoring data analysis, the final composite can be drawn streaming wetland relatively precise theoretical operating parameters. The actual operation of the project data is the use of actual project data online instrumentation, the actual operation of the process is about to flow, water temperature, PH and other data use24hours of on-line monitoring instrument recording, can be found at any time; PLC device to Jinxi transmitted through sewage treatment plants in the control room, the data stored in a computer instrument, so can reduce manual monitoring of labor intensity, but also to ensure the timeliness and accuracy of data records; sewage dissolved oxygen (DO), potential (ORP) data such as the use of portable instrumentation monitoring; while for sewage water samples of COD, BOD, total phosphorus, ammonia nitrogen, total nitrogen and SS and other indicators can be sampled periodically sent Jinxi sewage treatment plant laboratory water analysis by specialized personnel be analysis.With the above experimental methods and data collection tools, analysis derive a suitable set of operating data, combined with the actual project, summed up a set for the current water quality characteristics and emission requirements of rural southern Jiangsu groove style complex flow wetland treatment system.
