摘要
借助于计算机技术,活性污泥工艺数学模型已发展成为一种成熟的工程工具,并在国外得到了广泛应用,成为一种标准的工程实践,而我国在该方面的研究和应用还处于起步阶段。介绍了基于BioWin污水处理工艺的数学模拟概念和方法,包括非常成熟的活性污泥工艺模型以及为整个污水处理厂工艺过程模拟而开发的新模型,如厌氧消化模型、pH模型、化学沉淀模型和污泥上清液的处理工艺模型(厌氧氨氧化模型);同时还介绍了BioWin模型在智利某污水厂水费谈判中采取的动态模拟、纽约市环保局管辖污水厂生物脱氮除磷升级改造、F.Wayne Hill污水处理工艺优化的全厂模型及高碑店污水四系列改造项目中的应用,说明了该模型在污水处理厂优化设计、运行以及改造中作为一种管理工具具有较高的实用价值和良好的应用前景。
With the aid of computer technology, the mathematical models for wastewater treatment processes have been widely and successfully applied abroad. However, their research and application are at an early stage in China. The concepts and methods of BioWin-based mathematical models for wastewater treatment processes, including well-established models for activated sludge process and new models developed for the whole plant, such as anaerobic digestion model, pH model, chemical precipitation model and model for treatment of sludge supematant (anaerobic ammonia oxidation model) were introduced. The application of BioWin model to the negotiation of water tariffs for a WWTP in Chile, the upgrading reconstruction of biological phosphorus and nitrogen removal process of WWTPs in New York City, the process optimization of F. Wayne Hill WWTP, and the reconstruction of Gaobeidian WWTP was also introduced. All these show that this model, as a management tool, has higher application value and better application prospect in optimal design, operation and reconstruction of WWTP.
