Description
Technical field
The utility model relates to the sanitary sewage disposal technical field, the special processor of reinjection into reservoir after especially a kind of sanitary sewage disposal.
Background technology
The gas-processing plant that is located in the northwest is big away from city, sanitary sewage change of water quality, and peripheral ecotope is extremely fragile, and winter temperature is minimum, and to reach-35 ℃ and day and night temperature bigger.The general technology that adopts of sanitary sewage disposal at present is: sewage → grille well → equalizing tank → hydrolysis anoxic pond → biological contact oxidation pond → settling tank → sterilization pool → discharging.Wherein in equalizing tank, establish preaerator, in biological contact tank, provide oxygen source by rotary fan, enter the settling tank flocculation after adopting porous water distributor aeration, clear water enters sterilization pool and handles the back discharging, and this technology floor space is big, is applicable to that the water yield is big, less, the envrionment temperature condition with higher of variation water quality, and must the special messenger be responsible for, mud is cleaning often, and labour intensity is big, can't satisfy the requirement that gas-processing plant effluxes after to sanitary sewage disposal.Therefore, press for production feature, geographical environment, water quality characteristic according to the gas field, develop a kind of fast, efficiently, the treatment unit of sanitary sewage re-injection cheaply.
The utility model content
The purpose of this utility model is: a kind of sanitary sewage reinjection into reservoir treatment unit is provided, the sanitary sewage of gas-processing plant is handled the back reinjection into reservoir, effectively alleviate the pollution of sanitary sewage to surrounding enviroment.
The technical solution adopted in the utility model is: sanitary sewage reinjection into reservoir treatment unit, mainly form by homogeneous jar, water pump, chlorine dioxide generator, retort, flocculation agent dosing tank, slurry tank, porous medium strainer, tundish, topping-up pump, fine filter, re-injection jar, sterilant dosing tank and re-injection pump, it is characterized in that: the liquid outlet of homogeneous jar has pipeline to connect the import of water pump, and the outlet of water pump has pipeline ligation jar fluid inlet; The dosing mouth of the outlet ligation jar of chlorine dioxide generator; The liquid outlet of retort has pipeline to connect the fluid inlet of slurry tank, is connected with the flocculation agent dosing tank at the retort liquid outlet to the pipeline between the slurry tank fluid inlet; The liquid outlet of slurry tank has pipeline to connect the import of porous medium strainer, the outlet of porous medium strainer has pipeline to connect the fluid inlet of tundish, the liquid outlet of tundish has pipeline to connect the fluid inlet of re-injection jar, is in series with topping-up pump and fine filter at the tundish liquid outlet to the pipeline between the re-injection jar fluid inlet; The liquid outlet of re-injection jar has pipeline to connect the re-injection pump; On the pipeline between re-injection jar liquid outlet and the re-injection pump, be connected with the sterilant dosing tank.
The processing technological flow of sanitary sewage reinjection into reservoir treatment unit is: pH regulator → dioxide peroxide oxidation → flocculation → sedimentation → porous medium filtration → fine filtering → sterilization → injection stratum.
Sewage carries out oxidizing, flocculating through solids constituent after the adjusting of, potential of hydrogen handles; After the dioxide peroxide oxidation,, make water in slurry tank, form flco, effectively remove trace suspension particle in the water by flocculation; After the former water that oxidizing, flocculating was handled enters the more medium filter filtration, enter tundish, after the topping-up pump pressurization, enter the re-injection jar after the arrival fine filter filtration treatment; After re-injection jar water outlet position adds the sterilant sterilization, inject the stratum through waterflood pump.
The beneficial effects of the utility model: the utility model sanitary sewage reinjection into reservoir treatment unit, can effectively remove suspended solid and oleaginousness in the sanitary sewage, handle the back water outlet and can satisfy the water filling standard, reinjection into reservoir is effectively alleviated the pollution of sanitary sewage to surrounding enviroment.
