| With the application of natural gas resources and the rapid development of the acceleration the pace of natural gas, producing a large number of oily wastewater. These resulted in the discharge of sewage pollution of the environment and water waste, the study applies to oil-field wastewater treatment control system is very necessary. Oily wastewater treatment methods at home and abroad generally deal with the high cost of technology, complexity, process high energy consumption, covers an area of large, to join secondary pollution caused by chemical agents such shortcomings, are not applicable to gas water a small amount of water after treatment Well, the characteristics of a small area of oil field waste water processing. In view of this, this paper studied with membrane separation - Catalytic oxidation of oily wastewater treatment process based oil-field wastewater treatment control system, the main research contents are as follows:By analyzing the gas targets oily wastewater discharge standards for primary treatment of sewage gas oil petroleum substances, suspended solids, COD pollutants, using membrane separation - catalytic oxidation process for handling these substances. Through testing, analyzing membrane best working conditions.This paper design oil field wastewater treatment system to analyze membrane separation - catalytic oxidation process of sewage treatment processes on the role of oil. Oily wastewater treatment system make the explosion-proof measures, ensuring the system security.Control systems using PLC controller oil field sewage disposal system. Oil field wastewater treatment system according to the distribution and transmission of signals between the system stability of the parameters, the preparation of PLC control program. PLC control cabinet real-time display the control system of the work achieved on the field control of oily wastewater treatment system, the sewage treatment process to normal operation. Through the membrane of the working parameters of control, so that oily wastewater treatment before and after the key indicators of pollutants has fallen more than 95%, the effect clearly. |
