Description
Technical Field
The utility model relates to the technical field of sewage treatment, in particular to a micro-electrolysis oxidation device.
Background
A large amount of produced water is generated in the oil and gas field exploitation process, and the produced water is a multiphase system which is formed by the primary processing processes of crude oil demulsification, separation and the like and integrates suspended solids, oil, dissolved gas and dissolved salt, wherein the produced water is exploited along with crude oil in a stratum. The impurities in the oil extraction sewage are mainly suspended solids, colloid particles, dispersed oil, floating oil, emulsified oil, dissolved substances and the like. And if the sewage is discharged without advanced treatment, the surrounding environment and the like are greatly affected. After treatment, the oilfield produced water can be re-used in water injection recovery, a so-called "produced water reinjection". The reinjection of the produced water can effectively reduce the requirement of oil and gas field exploitation on fresh water, and has important significance for saving water resources.
The polymer flooding oil sampling technology is one of important technologies for improving recovery efficiency in the tertiary oil recovery process of an oil field. However, polymer flooding improves crude oil recovery efficiency and simultaneously generates a large amount of polymer flooding produced water, and the polymer flooding produced water has higher oil content and suspended matter content than the traditional produced water, and is more difficult to treat, and direct reinjection can cause stratum blockage, damage to a rock core, increase of water injection pressure and reduction of recovery efficiency. Compared with water flooding produced water, the polymer flooding produced water contains substances such as petroleum hydrocarbon, solid particles, inorganic salt, bacteria and the like contained in conventional oil extraction sewage, and has the characteristics that 1, a large amount of residual HPAM is contained, and the concentration can reach about 500mg/L when the concentration is high. 2. The viscosity of the sewage is high. 3. The initial particle size of the oil globules in the sewage is small. 4. The degree of emulsification is enhanced. 5. The quality of produced water is generally poor. So the treatment difficulty of polymer flooding produced water is more.
In the reinjection process of the produced water, the water quality of the produced water meets the relevant requirements of the water quality index and analysis method of water injection of clastic rock oil reservoirs SY/T5329-2012, so that suspended matters, floating oil and emulsified oil in the produced water need to be removed. At present, high-efficiency and low-cost treatment technology for polymer-containing produced water of oil and gas fields is still lacking.
The micro-electrolysis reactor is equipment for treating high-concentration wastewater, and the filler filled in the reactor can greatly improve the biodegradability of the wastewater and remove chromaticity and heavy metals. Is a novel sewage treatment device widely applied at present. However, the traditional micro-electrolysis reaction device generally adopts a cylindrical structure, water flow enters from the bottom, so that the problem of uneven water distribution often exists, the problem of passivation, hardening, blocking and channeling of the filler are caused, and an isolating layer is easily formed between the iron and the carbon because the iron and the carbon are in physical contact, so that the filler is passivated, and the micro-electrolysis material needs to be replaced frequently, so that the resource waste is caused.
