This paper introduces the development process of wastewater disposal,it's auto control system,the level of nowadays and several new techniques of China and foreign countries. The immanent structure,control rules,main features and design methods of auto control systems in wastewater disposal process are studied in this paper. Aiming at four typical parameters,such as temperature,dissolved oxygen,PH and the planes of water,the Distributed Control System is designed,composed by PC called epigyny computer and SCM 8098 called hypogyny computer,and some sensors,shift deliver utensils and related meet orifices of parameters gathering and figures communication. The idea and work processes of some program modules are also introduced here. The programs in epigyny computer include the program of mutual interface between operator and computer,figure disposal program and chart output program,which are exploited with Visual Basic 6.0. And the programs in hypogyny computer are composed by figure gathering program,the progr am of supervision and control of system,communication program and meet orifice program between assemble language and VB,which are designed with assemble language.
