Water separation device.
Background technology
Oil-polluted water is a kind of common industrial wastewater, and along with developing rapidly of national economy, oil exploitation, oil add
The oily waste water water yield that all conglomeraties such as work, machining produce also gets more and more.And the harm that environment is caused by oily waste water is also
Increasing, the harm of oil-polluted water is mainly manifested in the following aspects: 1. affect drinking water sources and groundwater resources, danger
Evil aquatic resources;2. it is detrimental to health;3. atmosphere pollution;4. production estimation is affected;5. destroy natural landscape, even also have
Probably due to the oil product of coalescence burns and produces safety problem.
Oil-water separation is the tap of the follow-up water treatment technology of oil-polluted water, the removal of oil-water separation particularly oil emulsion and point
From, it is one of emphasis and difficult point, oil-water separation will directly affect the operation result of whole water treatment system.Oil emulsion is grain
Degree is the superfine oil droplet of 0.1~10 μm, owing to oil-water interface has the existence of surfactant, generally steady with oil-in-water form
Surely being dispersed in water, separating difficulty is relatively big, and the removal effect of oil emulsion is managed by tradition by the degreasing technique of oil-polluted water not to the utmost
Thinking, also needing often to be aided with the leading breakdown of emulsion processes such as electrolytic flocculation, its energy consumption and material consumption are bigger.
And the oil-water separation precision of the most commonly used oily water separating equipment is low, easily block, improper complicated component
Oil-polluted water, therefore hinders the development of industrialized production.
In sum, a kind of oil-water separation precision being presently required high, cost performance is high, it is possible to adaptive element complicated containing greasy dirt
Water, can industrially scalable use oily-water seperating equipment.
