A significant reduction of disease severity was observed on plant with BNR treatment compared with the non treat seedlings.

与未处理对照相比，BNR处理水稻植株的纹枯病害严重度明显降低。

It is necessary to study the characteristics of microorganisms in the sludge in order to efficiently evaluate the biological nutrient removal (BNR) process.

为了有效地评价除磷脱氮工艺，有必要研究污泥中微生物的特性。

Nitrogen and Phosphorus are restricted severely to prevent the water eutrophication. Biological nutrient removal (BNR) is an important water pollution control technology.

为遏制水体的富营养化，氮、磷的排放标准日趋严格，生物脱氮除磷工艺能有效地去除水体中的氮、磷。

This problem associated with COD limitation can be solved by introducing denitrifying phosphate-accumulating organisms responsible for anoxic phosphorus uptake into BNR processes.

而反硝化 聚磷使反硝化与 聚磷这两个需 碳源的过程合而为一，从而可以解决 碳源的双重消耗问题。
