摘要: Abstract Duckweed Lemna minor was cultivated in human urine (HU) and the effect of type, dilution factor, temperature, existence macro- microelements on growth rate investigated. The simultaneous removal nutrients selected antimicrobials also studied experiments with HU treated domestic wastewater, while starch protein content biomass determined. Higher rates were observed at 24 °C, using stored for 1 d factor equal to 1:200. In COD, total phosphorus nitrogen exceeded 80%, 90% 50%, respectively, ciprofloxacin sulfamethoxazole eliminated by more than 80%. main mechanism former antimicrobial photodegradation, plant uptake biodegradation seem be significant importance latter. Crude reached 31.6% harvesting, enhanced when duckweed transferred water 21 d, reaching 47.1%.
