Water resource is the basis of human lives.In recent years, the problem of many countries all suffer from shortage of water resources.Middle water returns
With being the effective measures of city water problems of improving the ecological environment, solve.Buck accounts for the 50%~80% of sanitary sewage, is at sewage
The precious resources of reason and reuse.Graywater treating method has Physical, chemical method, bioanalysis etc..In addition, many researchers also grind
The combination of two or more methods is studied carefully.The parameter and purposes of water outlet are the key factors of Screening Treatment method.
In buck, bath wastewater pollution level is lighter, and intractability is low, and discharge capacity is big, is easy to shunt and collect,
It is suitble to original position reuse.Practice have shown that bioanalysis need professional carry out operational management, processing unit can not household, and hold
Peculiar smell is easily caused, harmful effect is generated to residential environments.Membrane processing method is there are fouling membrane, chemical sludge pollution and cannot effectively go
The shortcomings of ash disposal disease caused by infectious water pathogenic microorganism.The physical chemistry methods such as activated carbon adsorption and chemical coagulation need to combine other technologies means
It can be only achieved the water standard of Treated sewage reusing.These technologies are unsuitable for the recycling processing technique in situ as bath wastewater.
Electric flocculation Bubble-floating Method is dissolved out using aluminium or iron anode, polymorphic poly-aluminium or the Polyferric Sulfate flocculation of in-situ preparation high activity
Contaminant particle in water body is assembled agglomerating and dissolved air flotation by agent.Electric flocculation Bubble-floating Method is efficient, secondary convenient for being separated by solid-liquid separation
Pollution is few, and manipulation and plant maintenance are simple, are easy to automatically control, and total molten solid (TDS) is small in final outflow water, is to meet bath wastewater
The technology technology that in-situ treatment reuse requires.But the problem of that there is also energy consumptions is excessively high for traditional electric flocculation technique, and electrode is easily passivated.

Reaction tank bottom；
(2) scrape off the dross generated during electric flocculation air supporting, collect water outlet and arrive secondary settling tank, it is to be precipitated completely after, be used for
It flushes the toilet.
The NaCl additive amounts are 0.5~2g/L, and conductivity is 2mS/cm after adjusting.
It is 0.5~3A that the power supply, which uses D.C. regulated power supply, setting electric current, and voltage is 5~30V, electric flocculation at this time
The air-floating apparatus opening time is 5~40min.
The sedimentation in secondary sedimentation tank time is 30~45min.
The main component of the electrode material FCSW is Fe, also contain the metallic elements such as a small amount of Cr, Mn, Ni and C,
The nonmetalloids such as Si, Cl, the main component of the wherein FCSW of Fe are Fe, mass percent 82.33%, followed by Cr and C,
Mass percent is respectively 12.00% and 4.07%, in addition also a small amount of Na, Mn, Si, C1, Ni and other full includes Al, S, Ca, K
With P etc.), mass percent is respectively 0.56%, 0.33%, 0.30%, 0.11%, 0.10% and 0.20%.
Beneficial effects of the present invention：For the present invention using FCSW as electrode, specific surface area larger FCSW is conducive to anode
Dissolving and Fe2+Diffusion, fluff structure be also convenient for electrolysis generate microbubble rising, can also as electrode use
Realize waste utilization.After optimizing reaction condition, stable effluent quality meets《Urban sewage reutilization urban reclaimed water water quality》
It flushes the toilet in (GB/T 18920-2002) water standard, realizes in-situ treatment reuse bath wastewater, there is good economic imitate
Benefit and environmental benefit.
