For being controlled whether unlatching and ensure that every pipeline reaches corresponding pump discharge to each connecting pipe
It is required that it is both provided with pumping installations and valve in above-mentioned each connecting pipe.
The concrete operating principle of the high extra large processing system of oily wastewater row in the port area is as follows：
The high oily wastewater in port area is discharged by sewage collecting pipeline in water tank 1 first, i.e., water tank 1 is first to containing greasy dirt
Water is collected；1 inside of water tank is provided with oil skimmer, realizes the primary separating treatment to the oil slick in sewage；Through water tank 1
Treated oily wastewater by discharge of pipes to then in sloping plate oil separation tank 2, will make oily wastewater in 2 sloping plate oil separation tanks into
Row oil removal is handled；Then oily wastewater is discharged by connecting pipe in coagulative precipitation tank 3, by adding coagulating sedimentation agent into pond
And be sufficiently stirred, the oil in oily wastewater, slag is made fully to react to form dregs of fat aggregate with coagulating sedimentation agent, after natural subsidence
It will be in the oil removing on upper strata, slagging-off sewage discharge to water quality adjustment pond 5；Sewage in water quality adjustment pond 5 is by adding pH adjusting agent
(such as：Sodium hydroxide, sodium bicarbonate, hypochlorite) adjust water body pH be in neutrality；Neutral sewage enters hydrolysis acid by connecting pipe
Change in pond 6, by the anaerobe in hydrolysis acidification pool 6, make the non-dissolved organic matter (oil droplet, petroleum-type) in water body
It retains and is gradually changed into dissolved organic matter, some are difficult to biodegradable macromolecular substances and are converted into be easy to degrade small point
Sub- substance such as organic acid etc., so as to increase substantially the biodegradability of waste water and degradation speed, in favor of follow-up aerobe
Processing；The progress membrane biological reaction stage in MBR reactors 8 is entered by connecting pipe by the acidification water outlet of hydrolysis acidification pool 6,
7 air blast computer room of period carries out bio-aeration, makes in pond special efficacy bacterium (particularly dominant bacteria in the increase of activated sludge concentration and sludge
Group) increase, the body refuse in waste water and suspended matter are effectively removed；The water outlet of MBR reactors 8 is discharged by pipeline to be loaded with
The adsorbent equipment 9 of activated carbon enters the further organic macromolecule material removed in water body of activated carbon adsorption stage realization, then,
The part water outlet of adsorbent equipment 9 is discharged into chlorination link into 11 reuses by the connecting pipe between reuse pool 11
In pond 11, at the same time, the first disinfection agent feeding device 10 is by connecting pipe together with the water outlet after charcoal treated
It returns to form water cycle system into reuse pool 11, and by the connecting pipe between water tank 1；Adsorbent equipment 9
Another part water outlet is then entered by connecting pipe in the first intermediate pool 12 staticly settle after by upper strata Chinese effluent to ultrafiltration
In device 13, water outlet by connecting pipe enter the second intermediate pool 15 in carry out it is secondary staticly settle, period second sterilizes
Agent feeding device 14 by the connecting pipe between the second intermediate pool 15 by disinfectant add in the second intermediate pool 15 in into
Row water body disinfection；The finally water outlet by disinfection carries out last processing heel row sea by discharging pond 16.
Wherein, it is to be promoted just to have removed the treatment effeciency of sanitary sewage, it can will be in sanitary sewage elevator pump by connecting pipe
Sewage be discharged into together in water quality adjustment pond 5, carry out pH adjustings, then sequentially enter the extra large processing system of the port area high oily wastewater row
In the subsequent processing device of system, common polluter smoking processing is realized.
In above-mentioned processing system, discharge pond 16 is crucial processing equipment last before row is extra large；Specifically, the discharge water
Pond 16 is an open babinet, and the water inlet 17 being opened on the end wall of babinet front end including one and two are opened in box back
Water outlet 21 on end wall；The suction that multi-disc is arranged in order and is mutually parallel is vertically arranged in the box inside of neighbouring water inlet 17
Oiled-plate method 18 is vertically arranged with the oil filtering plate for oil 19 that multi-disc is arranged in order and is mutually parallel in the box inside of neighbouring water outlet 21,
Floating oil collecting device 20 is provided with above cabinet space between oil absorption plate 18 and oil filtering plate for oil 19.
Wherein, oil absorption plate 18 includes double-layer filtering net and the oil absorbent material being arranged between double-layer filtering net.Filter screen is not by
Rust steel outline border and the steel wire being fixed in outline border are formed, and steel wire is 300 mesh.Oil absorbent material is melted for lipophilic superfine polypropylene
Spray fiber, have can liquid such as greasy dirt, hydrocarbon, vegetable oil of absorption weight decades of times itself rapidly, there is adsorbance
Greatly (10~25 times dead weight), adsorption rate is fast, and intensity is big, and toughness is high, and stretching resistance is strong, cleaning is light, and it is excellent that fiber is not easily to fall off etc.
Point；The modes such as burning can be used after use to handle, high temperature, which incinerates ashes, only remainings 0.02%.In addition, to ensure that oil absorption plate 18 obtains
It fully efficiently uses, is respectively opened up in the oil absorption plate 18 being arranged in order in multi-disc there are one discharge outlet, and adjacent two panels oil absorption plate 18
On the discharge outlet that opens up be respectively adjacent to the both sides of babinet and open up, make in broken line mode successively to pass through by the intermediate water of oil absorption plate 18
Each oil absorption plate 18.
Oil filtering plate for oil 19IncludingDouble-layer filtering net and the filtrate being arranged between double-layer filtering net.Filter screen is by stainless steel outline border
It is formed with the steel wire being fixed in outline border, steel wire is 300 mesh.Filtrate is the fibrous nodules formed by filament ligation, is fitted
For the fine filtering of all kinds of oily wastewaters, the adsorption capacity of oil and organic matter is enhanced；Filtering layer hole when modified fiber ball is run
Gap rate is gradually reduced along water (flow) direction, forms more satisfactory filtrate hole distribution, good filtration effect, filtering velocity height.
Floating oil collecting device 20 selects the miniature floating oil collecting machine of dynamic equilibrium overflow-type, is set to coastal waters, makes collection
Stream device is suspended in the water surface naturally, always by the inside overflow of extraneous liquid level bubble through the water column on thin layer liquid level, and by suction tube
Road negative pressure enters knockout drum, and oil product carries out separation discharge in negative-pressure cup, avoids the strong stirring and emulsifying of suction pump, makes grease
Separation is easily thorough.Sump oil discharge after separation is collected, and water flows back to water body.
After tested, the discharge pond 16 is good to the treatment effect of oily wastewater, water quality oil-containing≤15mg/L, suspended matter before filter
≤10mg/L；Water after filter matter oil-containing≤5mg/L, suspended matter≤2mg/L.
As it can be seen that the discharge pond 16 can realize efficiently separating for grease, join with the other equipment of the row sea processing system
With effectively being carried out to port area oily wastewater, the oily waste water being processed made to reach the extra large discharge standard of country row, relative to existing
Have and be doubled with equal its day treated sewage efficiency of port area oily wastewater system.
