제안 방법
- Each aquarium was filled by 20L of diluted wastewater and losses in culture volume due to evapotranspiration was maintained by the addition of deionized water to the original level prior to the day of sampling so that deionized water additions would minimally impact measurements[10]. The experiment was conducted over a 1 month period, during which observations were made of changes in appearance and growth of the plants. Through out the study the growth chamber was adjusted 24℃ temperature, 60% humidity and alteration of photoperiod(12h light and 12h dark).
- Roles includes the physical effects of the plants themselves in sedimentation, erosion control and providing surface area for microbial growth(Bioflims), thus increasing microbial assisted processes including nitrification and denitrification. The objective of the current study was to compare the potential of three floating aquatic macrophytes in monoculture and mixed culture system, in removing the total nitrogen, ammonium nitrogen, total phosphorous and organic matter from domestic wastewater and to establish their role in improving water quality.
- The treatments were evaluated by measuring the chemical parameters in grab samples. Samples were obtained by dipping a 100ml graduated beaker at the center of aquarium.
- Care was taken to minimize disturbance of the plants. The wastewater in each aquarium was sampled 9 times over a 32 day period, on days 0, 4, 8, 12, 16, 20, 24, 28, and 32. The parameters measured included chemical oxygen demand(CODcr), total nitrogen(T-N), ammonium nitrogen(NH3-N), total phosphorous(T-P).
이론/모형
- The T-N was measured in portable spectrophotometer at 410nm(model# HACH-DR-2800). Ammonia was determined by Nessler Method by using test kits. For the ammonia test 1ml filtering sample was added in the test kit tube and added 4 drop of solution S1 and 1ml of solution S2.
