Description
Technical field
The present invention relates to oiliness sewage treatment field, furtherly, relate to a kind of oil-containing waste water treating device and method.
Background technology
In oiliness sewage treatment, advection oil separation tank and sloping plate oil separation tank are conventional treatment process.Advection oil separation tank is the suspended substance utilizing pond length to remove oil-in-water and the sinking of floating.Sloping plate oil separation tank (being arrange unidirectional swash plate group to utilize the swash plate area increased to remove the suspended substance of oil-in-water and the sinking of floating in pond), sloping plate oil separation tank floor space is only 1/3 ~ 1/5 of advection oil separation tank, there is data introduction wastewater temperature 30 DEG C, waste water proportion is 0.996, the proportion of oil is under the condition of 0.9, for the oil droplet that diameter is 60 ~ 90 μ, the clearance of sloping plate oil separation tank is 94%, and advection oil separation tank is 64%, for the oil droplet of diameter 90 ~ 120 μ, the clearance of sloping plate oil separation tank is 100%, and advection oil separation tank is 75%.In treatment process, advection oil separation tank management and operation and maintenance convenient, be generally used, but take up an area very large, atmospheric pollution is more serious.Sloping plate oil separation tank is owing to being unidirectional swash plate group, if the mud that current are just conducive on plate by swash plate from top to bottom comes off, but be unfavorable for that the oil droplet in water floats, float if current are just conducive to oil-in-water pearl by swash plate from bottom to top, but be unfavorable for that the mud on plate comes off, there is easy blockage problem, conventional sloping plate oil separation tank due to the blockage problem turnaround very short, not easily play its advantage.
Theoretically, sloping plate oil separation tank is according to genuine " shallow layer precipitating " principle design in Kazakhstan.Ideally: L/H=V/U
o, the length in a L-----pond, the degree of depth in H-----pond, the horizontal flow velocity of V-----, U
o-----sedimentation speed of particulate matter in water, if H is divided into 3 layers, every layer is H/3, at U
owith under the condition that V is constant, only need L/3 just can by U
oparticle removal.Briefly pond body is more shallow, and the settling height of colloidal solid is shorter, and sedimentation effect is better, and swash plate is exactly when not increasing pond bulk area, increases desilting area.

Comprise:
Oily(waste)water is intake by one end, intakes bottom the first swash plate group through inhalant region water distribution grid, and top water outlet flows to the second swash plate group top, then from water outlet bottom it after the water distribution grid of exhalant region by the other end water outlet, complete first treating processes; After treated for some time, change Inlet and outlet water direction, carrying out process completes second treating processes in the other direction; Two treating processess hocket.
The present invention specifically can by the following technical solutions:
Oil-containing waste water treating device of the present invention comprises diagonal angle and arranges swash plate group and the swash plate group that is arranged in parallel, passes in and out pool, water distribution grid, sludge discharging area, Shou You district.
Oiliness sewage treatment process is as follows:
Oily(waste)water enters treatment unit from water inlet pipe valve, change the direction of a stream of water through flow deflector and eliminate kinetic hydraulic energy and flow into downwards, at this moment have the oil droplet that partly can float in waste water and float up to Shou You district, sedimentary clay Automatic-falling on inlet damper and minimizing Shou You district undulation, be conducive to receiving oil, waste water from bottom to top flows to the first swash plate group through inhalant region water distribution grid, in the process, oil droplet buoyancy direction in water is identical with flow action force direction, oil droplet can accelerate to float and mutually collide to form large oil droplet, larger oil droplet is formed when touching swash plate, buoyancy becomes large oil droplet by floating to Shou You district between plate, in the process, the gravity of the suspended particle in water is contrary with flow action force direction, will deposit in the first swash plate group when macrobead gravity is greater than bourn acting force, when mud in first swash plate group deposits to certain thickness, depart from the first swash plate group under gravity and slide into sludge discharging area, because the direction of motion of mud and water (flow) direction are reverse, sedimentary clay can be made to come off and to have resistance, sedimentary clay does not come off for a long time will block swash plate passage, flow area is reduced, waste water flows to the second swash plate group by the first swash plate group, in the process and just in time contrary in the process of the first swash plate group, it is reverse flow that current and oil droplet float, resistance is produced to the floating of oil droplet, the sedimentation of current and mud is concurrent, the reactive force of current adds that the self gravitation of mud makes the mud on swash plate be easy to come off and sink to sludge discharging area, waste water flows into through exhalant region water distribution grid and receives pool, also have a small amount of oil droplet in waste water after the first swash plate group and the second swash plate group process and float up to Shou You district, waste water after process flows out through water outlet pipe valve, complete a treating processes, after running certain hour, switch Inlet and outlet water direction, water outlet originally changes water-in into, water-in originally changes water outlet into, waste water is flowed into by pipe valve of intaking, enter inhalant region (former exhalant region), the second swash plate group is flow to through water distribution grid, second swash plate group water outlet flows into the first swash plate group, first swash plate group water outlet enters through water distribution grid and receives pool, waste water after process flows out through water outlet pipe valve (former water inlet pipe valve), complete second treating processes.
The present invention has following effect:
(1) oil and mud are separated, for subsequent treatment process creates good condition from waste water;
(2) inclined plate packing improves the specific surface area contacted with water, improves the clearance of oil-in-water and suspended substance;
(3) floor space for the treatment of unit is decreased;
(4) alternately changing Inlet and outlet water direction can make the mud that swash plate deposits slide to rapidly sludge discharging area, bottom when its gravity is identical with flow action direction, solves the problem of swash plate blocking;
(5) the large oil droplet of the mutual collision formation of little oil droplet floating can be accelerated be separated from water when water (flow) direction is identical with the buoyancy of oil;
(6) present treatment device is a processing unit, multiple processing unit serial or parallel connection can be selected to combinationally use according to water quality and quantity.
