Description
Technical field
This utility model relates to sewage treatment area, particularly relates to a kind of electroplating sewerage processing system.
Background technology
Metal ion in sewage that Electroplate Factory discharges and waste liquid, with the presence of with simple cation form, with the presence of with acid group form, have still belongs to carcinogenic and clastogenic extremely toxic substance.How poisonous electroplating sewerage is, and hazardness is relatively big, unprocessed electroplating sewerage up to standard enter river course, pond or in depth under, not only can endanger environment, and can polluted drinking water and water for industrial use.The Cr VI meeting environmental pollution contained in electroplating sewerage and serious harm human health, it is therefore necessary to be acted upon in earnest.
At present, being commonly used for the system that electroplating sewerage processes, widely used have a following different types of processing method: chemical precipitation method, is divided into again neutralization precipitation method and sulphide precipitation；Solvent extraction and separation method；Absorption method；Oxidoreduction facture, is divided into again chemical reduction method, ferrite process and electrolysis；Ion exchange；Membrane separation process technology；Biologic treating technique.
The above processing method, mostly using pool system in practical application, though applying the techniques such as the above chemical precipitation method, solvent extraction, absorption method, oxidoreduction in systems, but being difficult to reach new Standard；And its process system floor space big (process ton water and take up an area about 1～2m2)；Handling process length and time-consuming；The chemical treatment technology that it uses produces a large amount of body refuses (up to 1%～2%)；Terminal water circulation use power after process is the lowest.Ion exchange, membrane separation technique, biologic treating technique, although technique has the one side of its advanced person, but owing to its cost of investment is big；Operating cost is high；Environmental requirement to water is high；It is difficult to be used alone；And owing to processing tail water without actual effect measure, it is easily generated secondary pollution.The pool system of most common of which includes reaction tank, sedimentation tank and clear water reserviors, when processing sewage, in reaction tank, generally add flocculant carry out flocculation reaction, preliminary sedimentation in sedimentation tank, then precipitating further in clear water reserviors, carry out the most again adsorbing, oxidoreduction etc. processes；In sum, all there is certain drawback or irrationality in current electroplating sewerage processing system.

This utility model produces and provides the benefit that:
Biologic treating technique and chemical precipitation method are combined by this programme, in sewage regulating reservoir, gas explosion device is used to strengthen the oxygen content in sewage and the mobility of sewage, and then the breeding of microorganism in enhancing sewage, to decompose the Organic substance in sewage, aoxidizing and absorb poisonous metal thing, not only high treating effect and cost are the lowest；In acidity after being decomposed by the microorganisms due to electroplating sewerage, and the flocculating effect that PAC, PAM are under mild alkaline conditions is optimal, therefore arranges alkali reaction pond, the flocculating effect of PAC, PAM can be made to reach optimal, and then contribute to the sedimentation of molecule；Therefore the electroplating sewerage processing system not only low cost that this programme provides, is enhanced the disposal ability of Toxic in electroplating sewerage and particulate matter simultaneously.
Preferred version one, as the further optimization to base case, described gas explosion device is arranged on bottom sewage regulating reservoir；Gas explosion device is arranged on bottom sewage regulating reservoir, can make bubble fully and waste water, improve the dissolved oxygen amount in sewage, can also strengthen the bubble stirring action to sewage simultaneously.
Preferred version two, as the further optimization to preferred version one, the alkali liquor in described alkali liquor adding tube is Ca (OH)2Solution；Alkali liquor uses Ca (OH)2Solution, can reduce cost, and in sewage, the calcareous of formation can strengthen flocculating effect as the nuclei of condensation simultaneously.
Preferred version three, as the further optimization to preferred version two, before described PAC reaction tank is arranged on PAM reaction tank；The flocculating effect of PAC is good, but the flco formed is more broken, and PAM contributes to less flco and forms bigger flco, before therefore PAC reaction tank is arranged on PAM reaction tank, can strengthen flocculating effect.
Preferred version four, as the further optimization to preferred version three, described alkali liquor adding tube, PAC adding tube and PAM adding tube is provided with regulation valve；Regulation valve is set and can adjust alkali liquor, PAC solution and the addition of PAM solution according to practical situation, both contributed to cost-effective, each composition can be made again to have given play to optimum efficiency.
