the ammonia and nitrogen

基本解释

After cultivated, the ammonia-nitrogen and sulphide content in it were determined.
培养接入菌种的臭液，测定其氨氮含量和硫化物含量。
Results show that the ammonia and nitrogen adsorption amount of packing is affected by the kinds, service time, filling mode and filling position.
结果表明填料的氨氮吸附量受填料的种类、使用时间、填充方式和填充位置的影响。
The analytic results show that the main affecting factors on the ammonia and nitrogen removal are temperature, the ratio of COD to nitrogen in influent and PH value etc.
对运行结果的分析表明：氨氮的去除率主要受温度、进水COD/氨氮比率、pH值等因素的影响。
