Two alternative methods measuring totalnitrogen of aquaculture pond soils, named totalAmmonia method and Nitrate method, were established.
本实验创立了二种水产养殖池塘底泥总氮含量简易测定法,分别称为总氨法和硝酸盐法。

The results show that in-depth treatment process have good removal effect for the COD, BOD, total phosphorus, ammonianitrogen, suspended particulate, turbidity, OIL and total iron of waste water.
The COD, ammonia and totalnitrogen (TN) removal efficiency were studied in the paper at low DO concentration in a pilot-scale A/O nitrogen removal plant treating domestic wastewater.
