查询词典 water-heater

In the first cultivation stage,as relatively high concentration of phosphorus,phosphorus from water column was removed to a certain extent by periphyton.The end of the incubation,as low concentration of phosphorus periphyton releases phosphorus to water column instead of removal phosphorus from water,this may closely relate to the alkaline phosphatase secreted by periphyton in water body.

从培养过程中水体磷的浓度变化来说，培养初期，水体中磷的浓度比较高，附着生物对其有一定的去除作用；培养后期，水柱中磷的浓度比较低，附着生物不但不去除水中的磷，而且还向水柱中释放磷，这可能与附着生物向水体分泌碱性磷酸酶密切相关。
