Pengolahan Air Limbah Hotel Dengan Metode Free Surface Constructed Wetland Menggunakan Tumbuhan Equisetum hymale

Abstract

Throwing domestic waste water directly to the drainage without treatment hadcaused the water pollution. The effect of water pollution can disturb the health andwater biota. One of simple technology to decrease the pollutant in the water isconstructed wetland. This research aims to determine the effectiveness of freesurface constructed wetland with bamboo plants in a peat soil water and treatwaste water using detention time 1,2,3 and 4 respectively 3 replications. Eachdetention time and repetition experiences the same treatment in terms of both thetype and volume of waste water. The Fluctuations of waste water, rain water andthe occupancy rate in this study were not taken into account. The quality parameterof water that was tested are pH, COD, TSS. Statistic calculation that was used inthis research is one way Anova (Analysis of variance). The result of the researchshowed that the constructed wetland with peat and water bamboo (Equisetumhymale) resulted the highest effeciency in decreasing pH from 8.5 to 6 or 29.41% ,COD from 97.7 mg/l to 43 mg/l or 55.98% , and TSS from 447.90 mg/l to 66.00mg/l or 85.26%. Constructed wetland with the media of peat and without using theplant resulted the highest effeciency in decreasing pH from 8.5 to 6.5 or 23.53% ,COD from 250 mg/l to 173 mg/l or 30.8% , and TSS from 447.90 to 79.20 mg/l or82.32% All result showed that constructed wetland can improve the quality of thewaste water.
