Description
Technical field
The utility model relates to a kind of device that separates or remove grease or oily mater or similar seston, particularly a kind of oily water refining plant.
Background technology
Utilize in the prior art settling tank leave standstill oily water with reach oil, behind the aqueous phase separation layer, again with the oil extraction of settling tank upper opening so that oil, water sepn.This refining plant and purifying method not only purification efficiency are low, and the oil concentration of purifying waste water is still higher, is difficult to reach emission standard, and purification speed is slow, purification expense height.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, and a kind of purification efficiency height is provided, and the oil concentration of purifying waste water is low, and purification speed is the oily water refining plant faster.
The purpose of this utility model realizes by following approach.
The oily water refining plant, comprise settling tank, settling tank has inlet, its structural feature is, the total series connection of two-stage settling tank at least, wherein, the oily water inlet of first step settling tank is positioned at the top in pond, treated water outlet then is positioned at the bottom in pond, and the oily water inlet of second stage settling tank then is positioned at the bottom in pond and is communicated with the treated water outlet of first step settling tank, and the treated water outlet of second stage settling tank is positioned at the top in pond.
The utility model utilizes the principle of oil phase and aqueous phase separation in the oily water, and promptly You density is bigger than the density of water, so the oil in the oily water is swim in water top.Like this, after oily water enters settling tank from the inlet of first step settling tank, oil will swim in the pond above, water is then arranged into next stage settling tank from the lower part outlet of settling tank.If the oil mass in the oily water is many, can't oil, water sepn is clear with the one-level settling tank, the above settling tank of then available secondary separates, until oil, the water sepn water after handle is reached emission standard.
What is more important the utility model adopts the mode that allows oily water curve mobile mode replace the direct current in original technology to leave standstill, make oily water enter from the upper entrance of settling tank earlier, and arrange into next settling tank from the outlet of settling tank bottom, finally have only water after the purification to flow out again and utilize from the top outlet of last step settling tank.Like this, just increased the flow process of oily water under the water condition and slowed down flow velocity sending on an equal basis, thereby in the unit usable floor area, improved the efficient that purifies, simultaneously because adopt the mobile oily water to replace the oily water that leaves standstill, increased the speed that purifies, thereby reduced the time that purifies, obvious this replacement has reached unprecedented effect.
The top that final water outlet is located at the last step settling tank is in order to keep the stable level of whole oily water refining plant, to avoid current too fast and cause oil, water sepn insufficient, thereby influence purification effects, also avoided if water outlet is located at last step settling tank bottom when stopping oily water, last step settling tank water drains and is adsorbed on phenomenon at the bottom of the pond.
The utility model first step settling tank structure is as odd number level settling tank structure, second stage settling tank structure is as even level settling tank structure, has a plurality of odd number level settling tank structures and one or a plurality of even level settling tank and is connected into one by the type of attachment of odd number-even number-odd number.
In order to satisfy the difference of different oily water oleaginousness, the settling tank of different quantities need be set, for example the oily water that oleaginousness is high then need adopt the series connection of a plurality of settling tank and forms multifeed clarifier and purify.The oily water that oleaginousness is low then only needs to adopt a few settling tank even single settling tank to handle can obtain gratifying decontamination effect improving.
The last step settling tank is the even level settling tank.
A kind of strainer is installed between first step settling tank treated water outlet and the second stage sump oil sewage inlet.
In order to strengthen the effect of oily water separation, employing is equipped with strainer in the bottom of adjacent two-stage settling tank pool wall, like this, the oily water after carrying out initial gross separation through the profit phase separation principle passes through the filtration of filter again, and obviously purification effects will have been strengthened greatly.
First step precipitation is as odd number level settling tank structure, second stage settling tank structure is as even level settling tank structure, total a plurality of odd number level settling tank structures and one or a plurality of even level settling tank are connected into one by the type of attachment of odd number-even number-odd number, on the passage of last odd number level settling tank treated water outlet and even level sump oil sewage inlet a kind of strainer are installed at least.
Can be according to the oleaginousness of oily water to be processed how much consider whether strainer all is installed in the bottom of the adjacent two-stage settling tank of per pass pool wall, but need at least in the end on the passage of an odd number level settling tank treated water outlet and even level sump oil sewage inlet, promptly the bottom of last two-stage settling tank pool wall is equipped with strainer.
The utility model is also that further strainer is a kind of quartz micropores pottery.
The quartz micropores pottery can be adsorbed on oil its surface and not blocking microporous again to make things convenient for the outflow of water, and when the oil that adsorbs on the strainer acquired a certain degree, water washed a little or wiping can re-use and need not to change, and provided cost savings.In the prior art not quartz-ceramics as oily, water sepn material, the utility model creatively is applied to it filter oil sewage, and has micropore so that water flows through on its surface.
By curve flow separating oil and water and adopt the quartz micropores pottery to work along both lines as these two kinds of filter types of strainer, can reach good decontamination effect improving, show that through experimental study purification rate can be greater than 99.9%, thereby reach the high standard discharging.The rate of waste oil recycling has simultaneously also improved widely.
This oily water refining plant is applicable to the purification of various non-oil in water emulsion oily(waste)waters, such as the oily water of the oily water of washing bay, industrial enterprise, oil field oily water or the like, and is not subjected to the restriction of concentration.
In sum, the utility model has following advantage compared to prior art: the purification efficiency height, and speed is fast, and the oil concentration of purifying waste water is low, and cost is low, is adapted to the oily water of different concns, uses floor space little, applied widely.
