污水处理是一个复杂的多变量、大滞后、强非线性的过程，其处理工艺日趋复杂，单凭设计和运行人员的手工操作已无法达到处理要求。计算机技术在污水处理中的应用，能够提高水处理质量、降低水处理成本。该文介绍了计算机模拟技术和自动控制技术在国内外污水处理中的发展概况和应用现状，为污水处理相关从业人员提供参考。%Wastewater treatment is a multi-variable,large time delay and strongly nonlinear process,which is more and more complex in treatment processes,and can not be designed and operated by manual workers alone. But computer technology is essential to improve water quality and reduce the cost of wastewater treatment. The computer simulation technology and automatic control technology were introduced in this paper. The development and application status of computer simulation technology as well as automatic control technology in wastewater treatment were summarized,which provided a reference for wastewater treatment related people.
