Development Of Wastewater Treatment Monitoring System In Huansanlian

Nowadays, petroleum and gas are still in common use all over the world. Usually, they are deposited in the container for the sake of transportation and the users. However, the problems of the pollution to the environment emerging during the development process are unavoidable. Wastewater is one of the byproduct which can not be infused into the river or reuse directly. Therefore, it is a very important subject to solve the problem of wastewater treatment effectively.The traditional wastewater treatment system can no longer meet the standard because of the lowness of the automation level and the safety level. This paper's starting point is to design a control system with safety,effectiveness,practicability.Based on a wastewater treatment system in Liaohe oil field, through research and analysis of the technical process, a monitoring system including monitoring software and working site controller was developed. In this paper, the total design plan, hardware configuration and network communication plan of the waste water treatment monitoring system are given. The people oriented monitoring software is developed by configuration software with the advantages of low-cost and short developing period. The computer monitoring software of public parameters based on KingView is developed. Using PLC widely in this wastewater treatment accounts for the security and reliability that are always paid more attention in industrial control field. Allen Bradley SLC500 is used as the lower level controller on site. The control system has many functions including remote control, alarm, data processing, history trend display and automatic report printing. After the installation and the commissioning, the system works steadily and well.
