Managing wastewater treatment plant (WWTP) based on respirometric analysis is a new and promising field. In this study, a multi-dimensional respirogram space was constructed, and an important index R_es/t (ratio of in-situ respiration rate to maximum respiration rate) was derived as an alarm signal for the effluent quality control. A smaller R_es/t value suggests better effluent. The critical R^’_es/t value used for determining whether the effluent meets the regulation depends on operational conditions, which were characterized by temperature and biomass ratio of heterotrophs to autotrophs. With given operational conditions, the critical R^’_es/t value can be calculated from the respirogram space and effluent conditions required by the discharge regulation, with no requirement for calibration of parameters or any additional measurements. Since it is simple, easy to use, and can be readily implemented online, this approach holds a great promise for applications.

基于呼吸分析法管理废水处理厂（WWTP）是一个新的有前途的领域。在这项研究中，构建了多维呼吸图空间，并导出了重要指标R _{es / t}（原位呼吸速率与最大呼吸速率之比）作为污水质量控制的警报信号。R _{es / t}值越小表明废水越好。临界- [R ^' _{ES /吨}用于确定流出物是否满足规定值取决于操作条件，将其特征在于，以自养生物异的温度和生物质比例。与给定的操作条件下，重大R ^' _{ES /吨}可以根据呼吸调节要求的呼吸图空间和出水条件计算出该值，而无需校准参数或进行任何其他测量。由于它简单，易用，并且可以轻松地在线实现，因此这种方法对应用程序具有很大的希望。
