Zusammenfassung: | The speed of urbanization—industrialization in Vietnam is increasing, which helps to boost the economy and at the same time create great environmental pressure. Industrial wastewater from production processes is always abundant and discharged continuously every day with diverse pollution components. Wastewater treatment of by simple and low-cost methods has been concerned. In this study, constructed wetland (CW) model using the
Brachiaria mutica
has been researched to evaluate the performance of Horizontal subsurface flow (HSSF) CW in treating industrial effluents. The model built with dimensions is 1.2 m × 0.4 m × 0.6 m and operated under 4 research organic load rates respectively 40; 60; 80; 100 kgCOD/ha.day. Average treatment efficiency of pollution parameters through study is COD 93.86%, T–N 97.46%, T–P 91.12%, TSS 83.07%, BOD
5
97.72%. The output concentration values of the pollution parameters are smaller than the allowable values in column A QCVN 40: 2011/ BTNMT. The results of this study will be the premise to find solutions for industrial wastewater treatment with easy to operate and environmentally friendly. The process of industrial wastewater treatment using CW planning
B. mutica
is simple and efficient. The success of this work is possible to expand research on wastewater treatment capacity of CW planning
B. mutica
with different kinds of wastewater such as domestic wastewater, livestock wastewater, medical wastewater.
