Investigation of Improvement of Artificial Wetland Systems of Agricultural Drainage Waters

Harmful substances in the wastewater negatively affect ecological balance by reducing dissolved oxygen concentration. High phosphorus and nitrogen compounds discharged into surface water resources may cause to eutrophication, due increased algal growth. In this study, Elodea densa (Egeria), Lemna minor (Duckweed), Micranthemum micranthemoides (Micra), Pistia (Water Lettuce), Ceratophyllum demersum (Foxtail) plants were investigated for removal of nitrate ammonium from rice field drainage water. Synthetic was prepared rely on literature real composition Samsun Bafra region. Artificial wetland studies carried out as individual systems order understand treatment ability each plant a combined system batch continuous flow mode. pH, electrical conductivity, oxygen, nitrate, values measured periodically. Results represented that revealed highest efficiency (77%) at end 1 day, followed (76%). It observed with increasing hydraulic retention time. system, 40%, while 51% first day. concluded successfully reduced content showed resistance high salinity. experiments under mode, 0.80 mg/L 0.10 mg/L, 1.90 1.40 yielding approximately 90% 30% 16th Studies have general importance type well residence
