| dc.description.abstract | The purposes of this experimental project are learning and comparing the result of the Vetiver confine time and the health of the plants in the community waste water. The waste water of this experimental are collected from the low-cost housing project Bang-Kruay (Pha-ngung Temple) in Prai Bang sub district, Bang Kruay district, Nonthaburi province. The experimentation of this project was built the 2 potholes. The first pothole was set by grow up the Songkha 3 Vetiver with the floating platform and the Songkha 3 Vetiver while the second set had only the floating platform without plants as a control. However, both of the potholes were control the lead time of confine the Vetiver on 7, 14 and 21 days. Parameters of this project are BOD, SS, nitrogen and the phosphorus.
The result showed that the pothole with the Songkha 3 Vetiver was effective more than the pothole that without the Vetiver. The best lead time of confine is 7 days and the performance of BOD, SS, nitrogen and phosphorus are 83.32, 80.31, 78.88 and 76.55 that calculated in percentage. Moreover, during the test process, the Songkha 3 Vetiver are treated and had the survival in 100%, well grew up, had the new spires, roots and the leaves. The waste water was on clear, less sediment, no foul odor. The Songkha 3 Vetiver was effectively for the community waste water treatment with the floating plat form. From the result, it can be treat the BOD and SS till 14 days, the | en_US |
