Description
[technical field]
The present invention relates to technical field of sewage treatment equipment, particularly the technical field of inverse oil contg sewage filtering unit.
[background technology]
Industrial production often produces a large amount of sewage, industrial sewage complicated component, there are silt, oil and oil-containing solids thing etc., and environmental pollution is comparatively large, can not directly discharge.Common sewage generally adopts more medium filter and fiber bundle filter to process, but general fibre bundle can only process the sewage of not oil-containing.
Water-and-oil separator mainly contains gravity method, absorption method, membrane separation process and coalescence.Utilize profit proportion different, can carry out initial gross separation, separation accuracy is not high, and effect and efficiency are all poor.Absorption method, sorbing material can be saturated very soon, and sorbing material is not long for duration of service, and the later stage needs desorption process, and practical value is lower, and processing costs is high, is not suitable for industrial production and uses.Membrane separation process processing accuracy is high, but technology is more immature, consumes energy larger.Coalescence uses various media filtration, and processing accuracy is adjustable, and filtering accuracy is higher, very practical and development prospect.
General water-and-oil separator is that water-in is positioned at top, and water outlet is positioned at the structure of bottom.If the water-in of filtrate is positioned at bottom, water outlet is positioned at top, be then inversion type, filter core is inverted, and under gravity, the partial impurities attached on filter core can fall, another part is attached on filtrate, and after using for some time, oil slick needs to discharge, otherwise be easily trapped in bottom filter, treatment effect reduces, and filtrate is saturated needs back flushing to be rinsed by pollutent, and greasy dirt is easily attached on filtrate, very not easily rinse, running cost is higher, affects the work-ing life of filter filtrate.
