The Technology Of The Changqing Oil Field Extraction Wastewater Treatment Research

On the research of Changqing oil field wastewater treatment present situation as a foundation, from the perspective of environmental protection and energy saving of oil extraction wastewater treatment recycle and the significance of reinjection water quality requirements analysis on the treatment of oil extraction wastewater, physical treatment technology, physical chemical treatment, biochemical treatment technology and chemical treatment technology the characteristic comparison. With oil production factory of oil extraction wastewater treatment and recycling of examples, discusses the Changqing oilfield wastewater treatment technology applied in common and their existing problems, and especially the widely used walnut shell filter treatment process were introduced, research of walnut shell filter in waste water treatment process of strong adsorption, sewage interception capacity, easy to regeneration characteristics, analyzing the typical walnut shell filter wastewater treatment technology. At the same time, in order to make walnut shell filter can be used repeatedly, to restore the walnut shell filtering material filter ability as the goal, the walnut shell filter dirt nature, walnut shell filter cleaning method and the serious study of the subject, and using the static test method to test various cleaning agents, looking for the best dosage ratio walnut shell filter, in order to achieve the purpose of maximizing the oil removal ability. I hope the paper can promote the oil extraction wastewater treatment process and cleaning technology continues to improve, increase oil production wastewater treatment using strength, improve the effective utilization of resources, reduce fresh water resource utilization, reduce the production cost of oil field, avoid the damage of ecological environment, promote social economy and environment harmonious development, ensure oil field science development and sustainable development of.
