effluent concentration

When high concentration HF wastewater is processed with two-stage chemical method, fluorine ion concentration of the treated water can meet the national effluent standard ( closs A).

采用两段式化学法处理高浓度HF废水，处理水中氟离子可达到国家一级排放标准。

The manufacturing of fiberboard is accompanied by a big amount of waste water, which contains rigorous concentration of pollutants. Along with the increasingly strictness of effluent standards, it is in dire need of the advanced treatment and recycling of the fiberboard waste water.

纤维板废水排放量大，浓度高，随着工业废水排放标准越来越严格，对其进行深度处理和回用势在必行。

So the effluent concentration is lower than that of Sichuan Standards.

治理后,其排放浓度,低于《四川省标准》的任一标准值.

After upgrading, the effluent COD concentration was hardly influenced, while the effluent TN and Ammonia nitrogen concentration could decrease a lot, the effluent concentration could also meet the emission control standard.

改造后出水COD浓度变化不大，而出水的氨氮和总氮的浓度有较大的下降，出水浓度能达到国家规定的排放标准。

However, the treatment on coking wastewater especially ammonia nitrogen in the coking wastewater is not satisfying at present which leading to the ammonia nitrogen concentration in effluent cannot meet discharge standards.

然而，目前对焦化废水以及焦化废水中氨氮的处理效果均不理想，导致出水氨氮的含量无法达到排放标准。

This proposed method was applied to determine the freely dissolved concentration of bisphenol A in a municipal sewage effluent.

采用本方法测定了污水处理厂排水口的双酚A的自由溶解态浓度。
