摘　　要：基于污水系统在线监测手段,利用水量平衡及污染物化学质量平衡模型,对污水系统问题进行定量、定位分析,准确识别出区域问题,并结合计算结果,可更合理的、更有针对性的安排整治工程类型及时序,有效节省投资,缩短工程周期,提升工程效果。以某片区污水系统为例,通过问题识别,量化问题点位分析,提出分三个阶段实施整治工程,污水处理厂进水BOD_(5)浓度分别可达到80.42、90.77、95.52mg/L,满足提质增效的目标要求的同时综合提升了方案费效比。Based on the on-line monitoring method of sewage system,the quantitative and positio-ning analysis of sewage system problems is carried out by using the water balance and pollutant chemi-cal mass balance model,and the regional problems are accurately identified.Combined with the calcu-lation results,the type and sequence of treatment projects can be more reasonable and targeted,which can effectively save investment,shorten the project cycle and improve the project effect.In this paper,taking the sewage system in a certain area as an example,through problem identification,quantitative problem point analysis,it is proposed to implement the remediation project in three stages,and the in-fluent concentration of BOD_(5)in the sewage plant can reach 80.42,90.77,95.52 mg/L respectively,which meets the target requirements of improving quality and efficiency,while comprehensively impro-ving the cost-effectiveness ratio of the scheme.
