摘要
采用温室内水培试验方法,研究了水培番茄对甲鱼养殖废水的净化和滤清作用。结果表明,水培番茄栽培系统对甲鱼养殖废水中的COD、NO2、3-N、NH4-N、P等有较高的净化率,其值分别为77%、33%、97%、100%。水培番茄植株根须和根毛对养殖废水中的悬浮物和固体残渣有良好的吸附和过滤性能,平均每棵植株根部可吸附和沉淀大约10—12g固形物。
An integrated aquicultural production system consisting of rich nutrient effluent drained from turtle-pond and aquicultural vegetable in plastic greenhouse is conducted in the present investigation.It has been found that the aquicultural system exhibited a significantly high ability in removal of chemical oxygen demand (COD), nitrite and nitrate, ammonium nitrogen, phosphorous with 77%, 33%, 97% and 100%, respectively.In addition, suspended solids and particles were effectively absorbed and filtered by root and/or root hair of the plants in the system.As high as 10-12 g particles could be absorbed and settled by an individual plant.
