With regard to engineering,if the effluent time is too short the wire loading of decanter of IAT will be enhanced. Take all factors mentioned above into account,when operating period is 4 hours,it is appropriate for IAT to take the mode of as the operating mode . Under this operating mode ,the average removal efficiency of the combined process is 81.1% and the average NH3-N concentratiion in effluent is 7.0mg/L which can meet the requirements of water qulity standard for urban miscellaneous water consumption.
C influence of influent COD Concentration on removal efficiency of NH3-N
Through adding glucose,the influent COD concentration is controlled between 157.7mg/l to 921.3mg/l. when the average influent NH3-N concentration is 33.7mg/l and the combined process is operated at optimal mode, the influence of influent COD concentration on removal efficiency of NH3-N is investigated. The results are shown is fig2

关于工程，如果出水时间太短电线载入酒瓶的内隐联系测验将得到加强。采取所有上述因素考虑到，当经营期为4个小时，这是适当的内隐联系测验采取的模式的经营模式。根据这一经营模式，平均去除率合并进程是81.1 ％ ，平均氨氮concentratiion出水是7.0mg / L时，可满足水质量标准，城市杂用水。
ç影响进水COD浓度对去除率对NH3 - N
通过增加血糖，进水COD浓度控制在157.7mg / L降至921.3mg /湖当平均进水氨氮浓度为33.7mg / L和合并的过程操作优化模式的影响，进水COD浓度对去除率对NH3 - N的影响。结果表明是图
Figure2.influence的进水COD浓度对NH3 - N的去除效果
图2表明，去除效率的NH3 - N的下降以及增加COD浓度。当进水COD浓度低于400毫克/升，增加进水COD浓度的影响氨氮去除效果的DAT /内隐联系测验略有下降。但是，随着进水COD浓度进一步提高，该NH3 - N的去除效率的DAT /内隐联系测验下降明显。这些现象表明，高浓度的有机物具有明显的抑制效果硝化。很难硝化下进行高浓度的有机物，因为异养细菌繁殖迅速，实现优势斗争基板和做。随着增加进水COD浓度，去除率对NH3 - N的BOCR出现上升的趋势，直。其原因可以被看作是增加进水COD浓度的结果是提高出水氨氮浓度的DAT /内隐联系测验。但出水COD浓度的DAT /内隐联系测验基本上不会改变。不变出水COD浓度和增加污水氨氮浓度的DAT /内隐联系测验使进水C / N比下降的BOCR随着增加进水COD浓度combinedprocess.then硝化率随C / N比下降
