Description
Technical Field
The utility model relates to a wastewater treatment device, in particular to an oil-containing wastewater separation and filtration integrated device.
Background
The oily wastewater refers to: contains fats (fatty acids, soaps, fats, waxes, etc.) and oils (mineral oil, animal and vegetable oil). The oily wastewater is characterized by high COD and BOD, and is industrial wastewater with large amount, wide range and serious harm. Therefore, the grease in the wastewater needs to be removed before being discharged or reused.
The oil exists in the waste water in the following three forms:
1. suspension oil: the granularity is more than or equal to 100 mu m, and the oil film can quickly float up after standing and float on the water surface by a continuous phase;
2. dispersing oil: the particle size is 10-100 μm, and the oil is suspended and dispersed in a water tank, can be coagulated into larger oil drops to float to the water surface under the action of standing or external force for enough time, and can also be further reduced to be converted into emulsified oil;
3. emulsified oil: the particle size is 0.1 to 10 μm (extremely fine oil droplets), and the oil-water interface is influenced by a surfactant, so that the oil-water interface is stably dispersed in water in the form of oil-in-water, and it is difficult to separate oil from water simply by a standing method.
At present, the oil-containing wastewater treatment process mainly comprises the following ten kinds:
1. the settling separation method utilizes the density difference of oil phase and water phase and the incompatibility of oil and water for separation, and belongs to first-stage treatment. The settling separation is carried out in the oil separation tank, and the common modes comprise a horizontal flow type mode, a parallel plate type mode, a corrugated plate type mode and the like, and the water flow state of the oil separation tank has great influence on the oil removal capacity and effect;
2. coarse granulation uses the difference in affinity of oil and water for the coalescing material to effect separation. When the oily wastewater passes through the coarse graining material, the fine oil drops in the oily wastewater are conglomerated into larger oil particles, thereby increasing the floating speed and belonging to secondary treatment. The coarse granulation method does not need additional chemical reagents, has no secondary pollution, small occupied area of equipment and lower capital cost. However, the oily wastewater treated by the method requires low inlet concentration, so the oily wastewater before entering the equipment must be pretreated, otherwise, the oily wastewater has high concentration (generally higher than 10mg/L) and needs to be further subjected to advanced treatment.
3. The filtering method utilizes the interception and inertial collision, screening, surface adhesion, coalescence and other mechanisms of a granular medium filter bed to remove oil in water, and is generally used for secondary treatment or advanced treatment. The filtering method has simple equipment, convenient operation and low investment cost. However, as the operation time increases, the pressure decreases gradually, and the back washing is required to be performed frequently to ensure the normal operation.
4. The membrane separation method uses a porous membrane as a separation medium to intercept oil and surfactant in oily wastewater and allow water molecules to pass through, thereby achieving the purpose of oil-water separation. It is suitable for oily waste water with high discharge requirement and small treatment amount.
5. The floatation method is to utilize the tiny bubbles of oil globule adhered to water to increase the buoyancy force and float and separate, and is mainly used to treat dispersed oil, emulsified oil and fine suspended solid which naturally float and are difficult to remove in oily wastewater by gravity separation.
6. The adsorption method is to utilize porous solid adsorbent to adsorb the dissolved oil and other soluble organic matters in the oil-containing waste water. But the adsorption capacity is limited (30-80 mg/g for oil generally), the cost is high, the regeneration is difficult, the application is limited, and the method is only used for the advanced treatment of the oily wastewater.
7. The coagulation method is that a certain proportion of flocculant is added into the waste water to generate oleophilic floccule in the waste water, so that micro-water oil drops are adsorbed on the floccule, and then the oil content is removed by a settling or air-floating method. The method has large dosage and large slag discharge amount, and is suitable for treating the emulsion oil or other fine suspended matters with large wastewater amount and low oil content.
8. The salting-out method is to add inorganic salt electrolyte into the waste water. The electrolyte drives all the cations of the oil drop diffusion layer into the adsorption layer to cause the damage of an electric double layer, the oil drops become neutral, and the attractive force among the oil drops is recovered to be mutually combined, thereby achieving the purpose of demulsification. The method has the advantages of low coagulation speed, long settling separation time, large occupied area of equipment and poor treatment effect on the oil-containing emulsion stabilized by the surfactant.
9. The electrolytic method includes an electrolytic coagulation adsorption method and an electrolytic flotation method. The electrolytic coagulation adsorption is to electrolyze emulsified oil waste water by using a soluble electrode. The electrolytic coagulation adsorption method has the advantages of small occupied area, simple operation, good treatment effect, relatively less scum amount and the like, but has the defects of large consumption of anode metal, large amount of salt used as an auxiliary agent, high power consumption, higher operating cost and the like.
10. The biochemical method has good effect of removing dissolved oil in water, but can not remove dispersed oil and suspended oil, and once the dispersed oil and the suspended oil enter the system, the biochemical system can be impacted greatly.
At present, when oily wastewater is treated, one or more of the processes can be selected according to the specific conditions of the oily wastewater for treatment, when one process is adopted for treatment, the grease in the wastewater is often not thoroughly removed, the treatment effect is influenced, for the mode of removing the grease by combining multiple processes, the wastewater needs to be continuously discharged into different equipment for treatment, the occupied area of multiple sets of equipment is large, and the wastewater treatment cost is high.
