Description
Technical field
The present invention relates to a kind of sewage disposal device, and in particular to a kind of skid-mounted system for oily waste water treatment.
Background technology
Many oil-polluted waters can be produced in industrial production, substantial amounts of SS and COD is contained in these oil-polluted waters, if directly
Discharge, will cause greatly destruction to environment.Oil is general in water to be existed in three kinds of forms, respectively：It is floating to oil, refer to elaioleucite grain
Footpath is more than 50um, the oil that static a period of time can voluntarily float；Dispersed oil, refer to elaioleucite particle diameter it is smaller be 10~50um, be scattered in
In water, the oil that can be floated is stood through the long period；Oil emulsion, refer to elaioleucite particle diameter it is smaller be below 10um, standing will not float
Oil.
The method for the treatment of oil-polluted water has at present：Physical, chemical method, physical-chemical process.
The major technique used in Physical is Gravity Separation technology, filter isolation technics, membrane separation technique.Deficiency
Place be oil content and suspension content it is higher in the case of, equipment scaling seriously corroded, filler is dirty stifled serious, equipment cleaning frequency
It is numerous, and energy consumption is higher.
Chemical method is mainly coagulating sedimentation, chemical conversion and neutralisation, for processing in oil-polluted water part colloid and molten
Solution property material, for oil emulsion in water.The electrostatic of colloidal particle is neutralized by adding medicament realization, adsorb, built bridge, will emulsified
Oil is separated out from sewage, reaches the purpose of purification.But, sewage after chemical Treatment to subsequent process flow and device requirement compared with
It is high.Otherwise, even if part colloid and dissolved matter in sewage are separated out, when supporting separation equipment separating effect is poor,
Good treatment effect can not be reached.
Physical-chemical process common method mainly has two kinds：Bubble-floating Method and absorption method.Bubble-floating Method is with micro-bubble by air
Form injection water in, bubble take sewage out of in sewage uphill process in suspension elaioleucite and suspension, reach water-oil separating
Purpose, coordinating with medicament can be such that the harmful substances such as part oil emulsion and suspension in water are effectively removed.But have the disadvantage：
When being changed greatly in face of leading portion water quality oil-containing, Bubble-floating Method effluent quality is unstable, and overhaul of the equipments is frequent.Absorption method is mainly profit
With the pollutant in adsorbent absorption effluent.But because adsorption capacity is limited, sorbing material replacement cost is higher, and Regenerated energy
Power is poor.
, mainly using one of three of the above method, itself SS and COD clearance is low, after treatment for existing sewage disposal device
Sewage do not reach the primary standard of sewage discharge, great hidden danger is brought to ecological environment, as national requirements is more and more tighter
Lattice, existing sewage disposal device can not meet requirement gradually.Additionally, existing sewage disposal device structure often compares
Greatly, high cost, and construction trouble.For example, using the sewage disposal device of air-float method, being usually provided with dosing pump, both increased
Cost, energy consumption, also result in the structure increase of equipment.
