| Oilfield solitary six joint station is mainly responsible for island in the east,two north 13 block of oil and gas water processing tasks,such as the area of basic for viscous crude oil,solitary six dirt before modification using two levels of gravity settling + cartridge degreasing,in rece nt years because of the development blocks in causing water quality deterioration after polymer injection,injection water contains a lot of polymer(PAM),increase water viscosity,and colloidal charge repulsion,enhance oil-water emulsion is serious,the purification harder and vicious circle,leading to the separation of conventional treatment method is difficult to solve high oil containing sewage water quality indexes such as problem,unable to realize sewage recycle,both to increase the water use,and it is difficult to solve the problem of sewage treatment,caused the passive situation of the production,urgently needs to adopt reasonable and effective new techniques,new methods to solve the problem of existing wastewater quality.After many experiments and pilot,finally determined by liaoning waffer sewage treatment co.,LTD.,the "air flotation + efficient degreasing flocculation reagent" wastewater treatment equipment,the secondary air float processing,dosing system,realized the dirty oil from containing poly sewage recycling,sludge filtration double efficacy,after continuous technical improvement and medicament is tie-in,a complete implementation of the small scale test to the application of full production and according to the actual impro vement of sludge treatment process,make it within a reasonable economic processing costs to achieve the high oil containing sewage wastewater quality index of the level A3,not only can replace the produced water reinjection,can also be used as reagents and mother liquid polymer injection allocation water,satisfy the security environmental protection index,and achieve the virtuous circle of sewage recycling. |
