Efficiency of reducing the Nitrogen and Phosphorus by using Aquatic plants in wastewater of local government in Yasothon

Abstract

The research is the study efficiency of reducing nitrogen and phosphorus by aquatic plants are necessary  aquatic plants which have a property to adsorb chemical which has the elements of nitrogen and  phosphorus. The purposes of this research was to study efficiency of reducing nitrogen and phosphorus  period and weight of roots which are proper in a adsorb nitrogen and phosphorus wastewater of local government  in Yasothon. The experimental design was the Completely Randomized design (CRD) and Fixed Effect Model It is experimental research in the laboratory to study 2 factors of period and weight of roots. Statistics used data analyzed compared of percentage, mean Experimental measurements of the nitrogen and phosphorus by three times the amount measured 48 time, Standard Deviation and F-test (Two-way ANOVA) Research findings were as follows that Within 45 days, the efficiency of reducing nitrogen 49.90%  ,the efficiency of reducing phosphorus 99.42% and within 30 days, dry weight of lettuce’s roots which are proper in a adsorb nitrogen and phosphorus  average 18.83 grams.  Efficiency Comparison of reducing nitrogen and phosphorus by aquatic plants and period variant productive reduction nitrogen and phosphorus Significantly level 0.05
