Approaches to Establish a Modeling WWTP with a Case Study in Qinghe WWTP

Abstract

A concept of Modeling WWTP (wastewater treatment plants) and a case study in Qinghe WWTP were described in the paper. The new concept of Modeling WWTP is to put each element, which composes the whole WWTP, including wastewater treatment process or units, constructions, controllers and sensors, etc., into a whole modeling system. That is, a virtual WWTP in a computer system will be set up, with the mathematic models to describe every component in the WWTP and some computer language such as C#.NET and Visual Basic, to achieve the functions of data transfer, analysis and simulation of the whole process. The ultima objective is to apply appropriate WWTP software and monitor systems to the wastewater treatment process, and to achieve process simulation and management, so as to afford more efficient and more stable control and management on WWTP.A successful Modeling WWTP includes a careful selection of mathematical model and simulation software, a dissective analysis of interaction and conversion between practical operation data and model parameters, a sufficient collocation of many kinds of online/inline/offline apparatuses which can afford the operation data, and a systemic construction of communication services which can collect and transfer the data from apparatuses, monitoring systems and simulation software. The paper illustrated the detailed approaches to establish a Modeling WWTP with a case study in Qinghe WWTP in Beijing, China.
