  • Abstract   In this study, we discussed the treatment efficiencies of different types of industrial wastewaters by several lab-scale constructed wetlands. The purpose this study is to decrease certain pollutants in the effluents from the industrial wastewaters treatment plants investivate the feasibility of water reuse and recovering. We divided the experiment into two stages, and three types of industry wastewaters ,including paper, steel and refiring, are in this study.
      In the first stage, the treatment efficiencies of controlling the flow rate at 6 mL/min higher that those controlling at 4 mL/min. However, sinece the amounts of phosphur were smalls in the industrial weatewaters, the removal efficiencies are not high enough. Thus, we added sewage and phousphate into the wastewaters in second stage of experiments with the best ratio of N : P of 4 : 1. The performance work of these two stage experiments did help to clean the nutrient of nitrogenous in the industrial wastewater, especially the refining industry comparing to the other two types of industries.
