Description
Technical field
The present invention relates to environmental technology fields, and in particular to a kind of electric flocculation laundrywastes processing method.
Background technique
China is poorest one of the country of global per capita water resource.With the raising of national life level, domestic water
Amount dramatically increases, and wherein wash water accounts for about the 20% of domestic consumption40%, particularly important ratio is accounted in domestic water.
Wherein washing water accounts for about the 40% of laundrywastes, and rinse water accounts for the 60% of laundrywastes.Laundrywastes is the lighter life of a kind of pollution
Sewage living, major pollutants are surfactant, grease stain, dust particle and clothes fiber etc..But by laundrywastes
It is directly discharged into water body without any processing, aquatic animals and plants can be caused to seriously endanger.And surface is living in laundrywastes
Property agent concentration increase, can form colloid in conjunction with other pollutants after discharge and also can to the processing of sanitary sewage, industrial wastewater
Have a great impact.
Electric flocculation technique has many advantages, such as that small, at low cost, the easy manipulation for the treatment of effeciency height, occupied area, secondary pollution are small.?
It is widely used in the processing of the industrial wastewaters such as dyeing waste water, wastewater from car washer, paper waste, electroplating wastewater.Electric flocculation reaction master
It to include that flocculation, air bearing effect, redox are generated big using the electrolysis of soluble anode (metals such as aluminium, iron)
The pollution in laundrywastes can be efficiently removed by hydrolyzing, being polymerized to multinuclear hydroxo complex by measuring aluminium ion and iron ion
Object.
Currently, the plate material that electric flocculation technique uses is the metals such as iron, aluminium, titanium mostly, due to laundrywastes meta-alkalescence,
Water quality pH, using aluminium sheet as soluble anode, is unfavorable for the cohesion of floccule, poor processing effect between 9.3~10.2.Iron
Plate generates Fe (OH) as anode, electrolysis2、Fe(OH)3So that effluent quality turns to be yellow.And titanium plate cost is too high, is unfavorable for extensive
It uses.Independent electric flocculation technique processing laundrywastes is poor to the removal effect of major pollutants (LAS), need to combine other technologies
Improve the removal effect of LAS in laundrywastes, the flock formed after electric flocculation reaction in the prior art is extremely small, passes through
The further purified treatment of filter easily results in blockage, it is difficult to backwash.
Summary of the invention
To solve problems of the prior art, the object of the present invention is to provide at a kind of electric flocculation laundrywastes
Reason method, electric flocculation laundrywastes processing method provided by the invention can overcome the removal effect of LAS in the prior art poor, easy
It blocks, be difficult to the problems such as backwashing.
To achieve the above object, a kind of electric flocculation laundrywastes processing method of the present invention is through the following steps that realize:
(1) laundrywastes is discharged in electrolytic cell, aeration plate is aerated while electrolytic tank electrolysis；(2) Wastewater by Electric is wadded a quilt with cotton when being electrolysed
Floccule caused by solidifying is attached on bubble caused by reaction, with bubble floating to liquid level, is struck off and is floated up to liquid level
Floccule carries out deslagging；(3) by treated in step (2), waste water is transported in the filter containing nanosponges, nanometer sea
The processing of laundrywastes is completed after silk floss filtering.
In the present invention, it is preferable that the anodes in electrolytic cells pole plate is made of stainless steel plate and aluminium sheet mixing, cathode pole
Plate is stainless steel plate or aluminium sheet；The plate interval is placed in the two sides of cathode plate.
Further, stainless steel plate and aluminium sheet number ratio are 1:1 in the anodes in electrolytic cells pole plate.
The pole plate spacing of the plate and cathode plate is 2cm~4cm.
Further, the aeration plate in the step (1) is nanometer aeration disk, the aeration quantity of aeration plate 6L/min~
20L/min。
The time of electrolysis in the step (1) is 5min~20min.
Current density caused by electrolysis in the step (1) is 2mA/cm2~7mA/cm2。
Compared with prior art, the beneficial effects of the present invention are:
As can be seen from the above technical solutions, in the laundrywastes processing method that technical solution of the present invention provides, electrolytic cell middle-jiao yang, function of the spleen and stomach
Pole pole plate improves flocculating effect in conjunction with aeration plate with the mixing arrangement mode of stainless steel plate and aluminium sheet arrangement well；Stainless steel
Anode is few compared with iron/aluminium anodes loss, not perishable, improves the service life of anode plate；Aeration plate uniform aeration, not only makes electricity
The floccule of flocculation generation attaches to aeration plate and is electrolysed on generated dual bubble, and floccule floats up to after liquid level convenient for receipts
Collection strikes off, and helps to dilute the density of hydrogen that cathode generates, and prevents the hydrogen aggregation in confined space from causing to explode.Using receiving
Meter Hai Mian further adsorbs the floccule not struck off, filters, and overcomes other materials and easily blocks, is difficult to backwash etc. and lacks
Point, easy to disassemble, cleaning, reuse and low in cost.
Electric flocculation carries out simultaneously with air bearing in technical solution provided by the invention, and the floccule that electric flocculation generates is with aeration plate
The gas of generation floats to the water surface and is cleaned collection, and nanosponges are further separated by filtration, and contaminant removal efficiency is high, is not easy to block up
Plug and backwash, and it is low in cost, suitable for industrial is promoted.The removal effect for overcoming LAS in the prior art is poor, easily stifled
It fills in, be difficult to the disadvantages of backwashing；It is poor to efficiently solve traditional electric flocculation method processing laundry water treatment effect, water outlet jaundice and muddy
Turbid, subsequent filter device bears the problems such as heavy.By laundrywastes processing unit of the present invention processing after water quality clarification and
It can reach reusing sewage standard.
