Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, light oil sewage integrated treating device of the present utility model has the pedestal 18 of a steel, and tilted plate separator 2, buffer tank 3, strainer 5, coalescing separator 6, adsorber 8, controlling box 7 are housed on the pedestal; Described tilted plate separator water inlet is connected with sump pump 1 by pipeline, and the water port of described tilted plate separator is connected with described buffer tank inlet by pipeline; The oil slick mouth of described tilted plate separator is communicated with a sump oil case 16 by pipeline; Described buffer tank water outlet is connected with described filter inlet by sewage pump; Described filter outlet is connected with described coalescing separator oily(waste)water inlet by pipeline; Described coalescing separator pure water inlet is communicated with described adsorber water inlet by pipeline, on this adsorber water purification output tube valve 9 is housed.The blow-off pipe of described tilted plate separator bottom is communicated with blowdown main road 17 by wash water valve 15, the blow-off pipe of buffer tank bottom is communicated with the blowdown main road by wash water valve 14, the blow-off pipe of filter bottom is communicated with the blowdown main road by wash water valve 12, the blow-off pipe of coalescing separator bottom is communicated with the blowdown main road by wash water valve 11, and the blow-off pipe of adsorber bottom is communicated with the blowdown main road by wash water valve 10.
In the present embodiment, how not sump pump adopts positive displacement pump, and this pump has stronger suction capacity, and flow is even, and oil content is not had the side effect of mechanical shearing emulsive.How sewage is by not being pumped in the tilted plate separator, and tilted plate separator adopts two-stage process to handle to remove oils and the suspended solids in the oily(waste)water.Oily(waste)water enters the water-and-oil separator inlet, this moment, flow direction made progress, this flowing of initially making progress, can guarantee that most free oil (oil slick) can be climbed to separator surface in the water, the oil slick gravity flow that rises to separator surface enters the sump oil case, and settled mud is regularly taken away.Sewage flows down to the separator bottom by first group of compact arranged coalescing-plate then.In the process that current move downward, oil droplet rising collision coalescence is at the lower surface of swash plate, and adverse current rises to the surface in pond.The swash plate angle of inclination is 60 °, has guaranteed higher suspended solid separation efficiency, and flowing under the current direction can help the cleaner plate face, guarantees the lasting optimization of water-and-oil separator processing property, reduces its maintenance workload.Sewage after the processing changes the flow direction once more on the surface, flow out below the sump oil baffle plate, flows through overflow weir, discharges from water outlet.Tilted plate separator separation efficiency height, the residence time of oily(waste)water in tilted plate separator is usually less than 10 minutes.Because the tilted plate separator in the present embodiment adopts the structure of prior art, is not described in detail at this.
Sewage gravity flow after tilted plate separator is handled enters buffer tank, and this water tank is provided with liquid level switch, has high-order and low alarm function.When water level reach a certain height, start sewage pump 4 automatically, when water level drops to certain position, stop lift pump automatically.Lift pump is sent into the strainer follow-up equipment to sewage and is continued to handle.A pipeline ball valve 13 is housed in the pipeline of sewage pump.
Referring to Fig. 5, in the present embodiment, strainer is a kind of pot type high efficiency filter, in be equipped with that contamination capacity is big, long service life, filter core that filtering accuracy is high, this strainer is made of wash water valve, thief hole, impulse mouth, pallet, filter core, housing, safety valve, drain, lifting swivel arrangement, differential manometer.Strainer adopts quick-opening device, and working service is very easy fast, good seal performance; The filter core contamination capacity that it adopts is big, long service life, and it is convenient to change, economical and effective.Strainer is as the protective device of coalescing separator and active carbon adsorber; has high filtering accuracy; can filter and remove tiny suspended contamination (>10 μ m), can effectively prolong coalescent filter core and the work-ing life of adsorbing filter core in the follow-up equipment, reduce operation expense.After sewage entered strainer, thicker particle can precipitate immediately, and thinner particle is tackled by cartridge surface, and last water purification enters coalescing separator through the outlet conduit outflow filter through the oily(waste)water inlet.
Referring to Fig. 6, Fig. 7, Fig. 8, the coalescing separator in the present embodiment is the oily water separating equipment that adopts international advanced coalescence technology.Described coalescing separator is made of tank body 601, the coalescent district 602 of filtration, come-up disengaging zone 607, oil collecting zone 608, and filtering left side, coalescent district is the come-up disengaging zone, and the right side is oily(waste)water inlet 603 and sewage draining exit 604.Be provided with a plurality of coalescent filter cores 621 in filtering coalescent district, be provided with oil collecting zone at come-up top, disengaging zone, the bottom is provided with pure water inlet 606 and discharge outlet 605, and the oil collecting zone top is provided with venting port 609 and oil discharge outlet 610.Described coalescent filter core has a cylindric inner framework 623 and a cylindric outer skeleton 626, the skeleton two ends are provided with end ring 622, described inner framework center one side is provided with polyester filtering layer 624, be provided with breakdown of emulsion layer 625 between described inner framework and the outer skeleton, the outside of described outer skeleton is provided with coalescent layer 627, drain layer 628 in proper order.The oily(waste)water coalescent filter core of flowing through from inside to outside, this filter core has special micro-filtration, breakdown of emulsion and coalescent oil content multi-efficiency.Coalescent filter core by the high precision micro-filtration, is effectively tackled the granule foreign in the water on the one hand, especially tackles greasy filth impurity such as the tangible ferric oxide of stable emulsion state, iron sulphide, helps follow-up breakdown of emulsion and coalescent function.Breakdown of emulsion and coalescent effect are by exotic materials oily substance extremely strong avidity and hydrophobic nature to be realized on the other hand, coalescent filter core comes out to become big oil droplet with small in the water, free oil content is coalescent, and make it rapid come-up, come together in the oil bag of oil collecting zone, oil-contg can directly discharge less than 5mg/l in the water after the processing; Strong (the import:<5000ppm of coalescing separator de-oiling ability of the present utility model; Outlet :≤5ppm), oil slick and oil in water emulsion in the energy effective elimination water; Coalescing separator de-oiling efficient height, disengaging time is short; Tensio-active agent is low to coalescent influence.
In the present embodiment, active carbon adsorber mainly is to realize its function by compacting charcoal absorption filter core.Activated carbon granule has very many micropores and huge specific surface area, and the organic pollutant in the water is had very strong physical adsorption ability, can effectively reduce organic content in the water, COD, colourity, peculiar smell etc., realizes the purpose of water quality advanced processing.
In the present embodiment, the Level Detection of the Level Detection of the open and close of sump pump, the open and close of sewage pump, buffer tank and control, sump oil case is all finished by controlling box with control, because what use is routine techniques, the electrical schematic diagram of controlling box reaches the wiring scheme omission with controlled member.
