Description
Method field
The invention belongs to wastewater treatment method field, more particularly to a kind of efficient low-consume rubber that can flexibly switch technique are useless
Method for treating water and system.
Background method
What the current processing method for Rubber Industrial Wastewater was often related to is physical treatment method (such as isolation method, absorption
Method, blow-off method, flocculence), biochemical treatment process method (such as anaerobism, anoxic, aerobic) and chemical treatment method (such as electrode polarization
Method, Fe-C Micro Electrolysis Method), for the above processing method, physical treatment method be primarily directed to can by (as isolation,
Absorption, stripping, flocculation) etc. means be just able to achieve the method and method of removal pollutant, and single physical treatment method can not
Realize effectively removing for dissolubility pollutant;Biochemical treatment process method is primarily directed to certain biochemical
The degradation and removal of pollutant, can general simple sanitary sewage lower to pollutant matrix content handle, the processing side
Method has certain requirement to the degradable degree and biodegradability of dirty water pollutant matrix, when not degradable or difficult to degrade have
When machine object proportion is larger, the numerous microbes of internal system lose the drop of pollutant because of excessively high pollutant impact load
Solution ability, and then not can guarantee pollutant has removal effect;Chemical treatment method can pass through addition primarily directed to certain one kind
Medicament or change internal system reaction condition come so that conversion occurs for dirty water pollutant matrix or transfer (such as forms precipitating, gas
Body etc.) a kind of processing method means, with achieve the purpose that remove pollutant matrix, however, for many both do not participate in chemistry
It, only will by single chemical treatment means the rubber pollutant that reaction can not be removed by changing reaction condition again for
It cannot achieve effectively removing for dirty water pollutant matrix.It is multiple in reply for single above-mentioned processing method based on this
Seem especially insufficient in terms of the pollutant control of miscellaneous ingredient, main reason is that, no matter taking physical treatment method, at biochemistry
Any one of science and engineering process and chemical treatment method method handle the pollutant matrix in rubber sewage.It is mainly removed
Dirty mechanism is determined according to self-characteristic possessed by different pollutants, this is certainly existed in actual sewage to pollutant
Limitation in matrix removal efficiency.To embody physical treatment method, biochemical processing method simultaneously in same processing system
With the common feature of chemical treatment method, this has just risen to the scope of combined technical method, and method, functionality are relative to list
One physical treatment method, biochemical treatment process method or chemical treatment method wants superior many.However, group technology is
By realize different processes by the combination of certain way, this also necessarily results in sewage treatment process construction
The problems such as increase of difficulty, device configuration complexity are deepened, treatment process occupied area increases and energy consumption increases, although
Assembled technological can show stronger contaminant removal capacity to the Rubber Industrial Wastewater processing of complicated component, but this is also to sacrifice and throw
Providing cost, increase system Construction difficulty, reduction utilization rate of equipment and installations, increase operation energy consumption, increase system O&M difficulty etc. is cost
And realize.
In conclusion existing method the problem is that:With regard to single physical treatment, biochemical treatment and chemical treatment method
For, existing method seems especially insufficient in terms of the pollutant control of reply complicated ingredient, main reason is that, no matter adopting
Which kind of method in physical treatment method, biochemical treatment process method and chemical treatment method is taken to handle the pollutant in sewage
Matrix, main defouling mechanism are determined according to self-characteristic possessed by different pollutants, this is certainly existed in reality
To the limitation in pollutant matrix removal efficiency in sewage;
There are sewage treatment process difficulty of construction to increase for the group technology of existing method, device configuration complexity is deepened,
The problems such as treatment process occupied area increases, although assembled technological can show stronger pollution to the Rubber Industrial Wastewater of complicated component
Object removal ability, but this is also to sacrifice cost of investment, increase system Construction difficulty, reduction utilization rate of equipment and installations, increase operation energy
Consumption, increase system O&M difficulty etc. are realized for cost;
Current most of sewage and wastewater treatment system facility is designed by design maximum water at a specified future date under normal circumstances
, it is required to start all set even if there is a small amount of sewage to enter processing system within one very long period under normal circumstances
Standby, only a small amount of or normal volume stain disease enters in processing system in handling practical stain disease treatment process, this certainty
Meeting presses the relevant device of design maximum parameter configuration so that under non-design maximum water state in original sewage disposal system
The problems such as low, the energy consumption waste of utilization rate of equipment and installations caused by process starting, frequent starting.
Summary of the invention
Existing method there are aiming at the problem that, the efficient low-consume rubber that can flexibly switch technique the present invention provides one kind is useless
Method for treating water and system.
The invention is realized in this way a kind of efficient low-consume Rubber Industrial Wastewater processing method that can flexibly switch technique includes:
When natural rubber production waste water is after type mechanical grate foul remover removes oil removal, micelle sundries, gravity flow enters setting pot, specific gravity compared with
Big most of silts and particulate matter will precipitate;Waste water passes through fixed pool capacity followed by waste water comprehensive adjustment pond
The effective of water is adjusted to realize the equilibrium for entering pollutant concentration in processing system;Waste water quality and water quilt in the pond
And, some organic pollutants in comprehensive wastewater again this simply hydrolyzed, keep the biodegradability of comprehensive wastewater further
It is promoted;
Under the active state of conditioning tank elevator pump, it is discharged followed by dissolved air flotation device, after coagulating of being offerd medicine
The suspension substance for removing part, the suspension substance of half dissolved state in waste water is removed, during which through air flotation effect
The machinery that the dross of generation then passes through Slag Scraping Device is swept, and is discharged into dross pond nearby by dross pipeline;And then waste water solution
Into 1# intermediate pool carry out further water quality and;And the waste water after homogeneous is continuously delivered to by lifting device
In iron-carbon micro-electrolysis tower, with continuously entering for waste water, waste water medium starts to play the effect of its electrolyte, waste water solution with
In primary battery environment composed by the anodic-cathodic of iron-carbon micro-electrolysis filler, along with numerous miniature galvanic cell reaction continuously into
Row, promotes numerous persistent organic pollutants fully degradeds to flow through iron-carbon micro-electrolysis with the increase of easily biodegradable organics content
The biodegradability of the waste water of tower greatly improves, work of the dross that electrolytic process generates then through its internal three phase separator being arranged
