It was studied to examine the changes of nitrogen sources in water hyacinth aquatic treatment systems (cultured area ; 0.3m^2,initial value of water hyacinth ; 600g, contacting time ; about 24 hr.). Influent was introduced from outlet of extended-aeration plants. Results in growthing period of water hyacinth (from early summer to fall) are as follows : 1) Total nitrogen was decreased by approximately 4 mg/l (22%) in average. Ammonium nitrogen was decreased by 2.8 mg/l, but decrease of nitrate nitrogen was not seen. 2) In basic water (pH≩6.5 ), decrease of ammonium nitrogen was seen remarkably. Conversely, decrease of nirate was seen slightly in acidic water (pH<6.5) according to t-test (risk rate : 10%). 3) It was suggested that nitrogen sources absorbed by water hyacinth were both ammonium nitrogen and nitrate, but rate of absorption by water hyacinth was depended to pH levels in culture water. |
