Problems solved by technology

However, in practical application, the three-stage treatment process has problems such as the large area occupied by the grease trap, the large amount of coagulant and coagulant used in the coagulation and softening tank, and the filter tank is easy to block, which causes gas production in oil and gas fields. The cost of wastewater treatment is high and the treatment

Abstract

The invention relates to the technical field of wastewater treatment, and in particular, relates to an oil and gas field gas production wastewater treatment system which comprises a coagulation softening tank, a first filter separator with a micro-interface oscillation regeneration function and a second filter separator with a micro-interface oscillation regeneration function; and the first filter separator with the micro-interface oscillation regeneration function is connected with a second water inlet of the coagulation softening tank, and the second filter separator with the micro-interface oscillation regeneration function is connected with a second water outlet of the coagulation softening tank. The first filter separator with the micro-interface oscillation regeneration function, the coagulation softening tank and the second filter separator with the micro-interface oscillation regeneration function are used for treating the gas production wastewater of an oil and gas field in sequence, so that the occupied area and the cost of the treatment system are reduced, the volatilization loss of natural gas condensate is reduced, and the concentration of surrounding VOC is reduced. The first filter separator with the micro-interface oscillation regeneration function and the second filter separator with the micro-interface oscillation regeneration function are simple in structure, more convenient to operate and use and better in treatment effect.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a treatment system for oil and gas field gas production waste water. Background technique [0002] In the process of extracting natural gas in oil and gas fields, some water will be produced together with oil and gas. It is usually chosen to remove it from the gas by using a dehydration device before the gas is exported or transported, because this type of wastewater contains crude oil. , so it is called oil and gas field gas production wastewater. If the waste water from oil and gas fields is not properly treated, it will directly damage the surrounding atmosphere, water body, and soil ecological environment, affect and cause the sublimation of oil field water bodies, and affect the surrounding living environment and human health. [0003] Oil and gas field gas production wastewater contains a large amount of petroleum, COD, chloride, calcium and magnesium ions an...
