Given few studies refer to the employment of constructed wetlands to polish secondary effluent and purify runoff simultaneously prior to replenishment of surface water, lab-scale combined oxidation pond-constructed wetland ecosystems used for treating the composite wastewater were established in this study, and the effects of four factors, each at four levels, on the treatment efficiency of the system...
Orthogonal experiment is used to find out the key influencing factors of desalinated seawater quality chemical stability during distribution process. The experimental results show that in ferruginous and PE distribution systems, dosing quantity of CaCO3 is the most important influencing factor, the less important one is running time, and the least important one is velocity. Also the most optimal horizontal...
