The Fujian Fengzhu Sewage Treatment Plant Design And Implementation Of The Aeration Device Control System

With the urban sewage treatment market development, BOT model widely used to speed up the construction of urban sewage treatment plants, reducing the financial burden in the near future, but also to promote the technology of choice is more reasonable and practical.This thesis, based on The Fujian Fengzhu sewage treatment plant, describes the process of the plant, process characteristics and the various technical indicators.Production process through a detailed analysis of the process, the relationship between the treatment effect of the sewage treatment system and the amount of aeration of the aeration device, and improve aeration rate control can not only make the sewage treatment works best, but also can save energy, avoid unnecessary waste. Sewage treatment the overall design of low-cost automatic monitoring system, Selection of GE’s VersaMax PLC and touch screen low cost real-time monitoring of the aeration device parameters according to the sewage process requirements to select the flow regulator, pressure regulator, alarm, interlock, and unit self-protection function, can be fully automated to open the vehicleimprove the wastewater treatment plant, labor productivity, reduce sewage treatment costs, and improve the compliance rate of sewage.Conducted a detailed study of the blower surge in the non-normal conditions anti-surge valve can not completely shut down for the scene, the development of the performance curve of the four seasons drift by adding the amendment of the blower inlet temperature offset blower performance. It also presents the problems encountered in the field debugging process. For example:the scene to change the role of anti-surge valve control is proposed to change the installation position of the throttle device to solve the big problems of the fluctuations in the outlet flow to identify the unit vibration is large due to a loose foundation, and no secondary Grouting.
