The accuracy of leak localization of conventional sensing cable systems is related to the current stability of constant current source. To improve the performance of sensing cable systems, a novel integrated method is proposed for distributed liquid leak detection and localization, which includes an online self-test and parametric self-calibration, adaptive threshold leak detection and alarm generation,...
Combined floating bed and bio-film constructed wetlands (FBCW) simulation system was built to treatment sanitary wastewater with filamentous of palm and non woven and Trifolium repens L. TN, NH3-N, NO3-N, NO2-N and pH were investigated for upper, middle and under layer wetland system by intermission operation continued 118 days under natural conditions. Results demonstrated that system into the stable...
Plant bio-filter series mixed flow constructed wetlands were used for treatment nitrogen, phosphorus and organic matter from eutrophic water-body. The technical design and purification effects of small-scale plots of integrated constructed wetland were described along with details of XiChe Lake eutrophic water. The results showed that the integrated constructed wetland systems had good purification...
