Background technology
The existing sewage treatment technology route of oil refining enterprise is generally: oil refining sewerage → oil removal system → floatation system → A/O biochemical treatment system → efflux.For the refinery of processing viscous crude or super viscous crude, the wastewater property of its generation is extremely complicated: contained sump oil separates than great, difficult in Pollutant levels height, easily emulsification, difficult degradation, the water.If still adopt the technological process of production of old three samples to be difficult to guarantee the water quality reaching standard discharging, therefore, need take new treatment technology for refinery's sewage of processing viscous crude or super viscous crude.
The utility model content
The purpose of this utility model relates to a kind of extremely-viscous crude sewage and carries out advanced treatment apparatus, solves condensed oil sewage difficult degradation, difficult separation, easy emulsive problem, guarantees the sewage qualified discharge.
A kind of extremely-viscous crude sewage described in the utility model carry out advanced treatment apparatus by grille well, flat flow settling bowl, pumping plant water collecting basin, one-level lift pump, sedimentation remove oil tank, inclined plate grease device, one-level air-floating apparatus, secondary air-floatation device, BAF, secondary hydrolysis acidification pool, CAST reaction tank water outlet lift pump, CAST reaction tank, one-stage hydrolysis souring tank, middle lift pump, Lan Mei skews the plate settling tank and coagulation basin constitutes; The grille well import is connected with sewage, outlet connects flat flow settling bowl inlet, the outlet of flat flow settling bowl connects pumping plant water collecting basin inlet, the outlet of pumping plant water collecting basin connects sedimentation by the one-level lift pump and removes oil tank and remove oil tank regulating tank inlet in parallel with sedimentation, sedimentation remove the oil tank outlet successively with the inclined plate grease device, the one-level air-floating apparatus, the secondary air-floatation device connects, the secondary air-floatation device is connected with one-stage hydrolysis souring tank inlet by middle lift pump, the outlet of one-stage hydrolysis souring tank is connected with CAST reaction tank inlet, the outlet of CAST reaction tank is connected with the secondary hydrolysis acidification pool by CAST reaction tank water outlet lift pump, the outlet of secondary hydrolysis acidification pool is connected with the BAF inlet, the BAF outlet is connected with the coagulation basin inlet, and the coagulation basin outlet skews plate settling tank inlet with blue U.S.A and is connected.
But sedimentation removes oil tank and regulating tank can also series operation of parallel connection, flexible to operation.Flooding quantity, water quality substantially just often, sewage can directly enter sedimentation and remove oil tank, this jar is provided with constant height, about the about 16～18m of water outlet liquid level, follow-up flow process need not to promote and all can realize gravity flowage, a flow equalization after guaranteeing jar.Flooding quantity is greater than 600m
3During/h, can open the regulating tank water intaking valve automatically, treat that being promoted to sedimentation through pump again when flooding velocity is steady enters follow-up flow process except that oil tank by water inlet pipe flow feedback signal; When showing that by import water quality in-line meter water quality is abominable, also can make sewage after regulating tank is handled, enter sedimentation through the pump lifting more earlier and handle, to alleviate the pressure of follow-up flow process by manually opening the regulating tank water intaking valve except that oil tank.
Sewage removes oil tank by sedimentation and flows automatically into the inclined plate grease device, and the sewage gravity flow enters two-stage air supporting processing unit and carries out breakdown of emulsion, flocculation, air supporting and further remove oil in water emulsion and colloidal attitude suspended substance behind the inclined plate grease.According to this sewage water inlet oleaginousness height, and high this problem of emulsification degree, for strengthening oil removing, guarantee the smooth running of biological treatment section, adopt the series operation of two-stage air-float technology.Skeleton construction is set, and three layers is the inclined plate grease device, and two layers is the one-level air-floating apparatus, and one deck is the secondary air-floatation device.Adopting this decoration form to significantly reduce takes up an area of and the underground works amount.
The flotation water outlet enters biochemical system and comprises that " one-stage hydrolysis souring tank and CAST reaction tank are removed most organic, ammonia nitrogen and residual petroleum class in the water inlet, reduce S in the water inlet simultaneously
2-, phenol and prussiate.
The water outlet of CAST reaction tank enters smart biochemical treatment unit and comprises: anaerobic activated sludge is housed in secondary hydrolysis acidification pool inside and filtrate and aerobic biologic membrane are equipped with in BAF inside, further reduce outlet water organic substance and ammonia nitrogen concentration, make its approaching or satisfied discharging table standard.
The BAF water outlet enters the water outlet unit of checking on and comprises: coagulation basin and Lan Mei skew the plate settling tank and monitoring pool guarantees that water outlet is up to standard, provides stable high quality water quality for later middle water reuse simultaneously.
