Description
Technical field
This utility model relates to sewage treatment area, particularly relates to a kind of flocculation basin processed for electroplating sewerage.
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.
But no matter use above-mentioned any processing method, precipitating sewage is all requisite link, settlement of sewage is generally carried out in sedimentation cell body and flocculation cell body, existing flocculation cell body be the most all directly by sewage after reaction tank introduces, then make sewage stand, and add flocculant, after microgranule settles, then oettIed sewage is drawn, be then for further processing, this method is owing to needs are by static for sewage a period of time, and therefore treatment effeciency is the highest；Because flocculant directly adds with granule, it is unfavorable for that flocculant disperses in sewage；And and sometimes for improve sewage treating efficiency, while precipitating, flocculation cell body also can introduce and effluent sewerage, but owing to the sewage in now flocculation basin body is in flow regime, to make flocculant to be distributed to uniformly in sewage, will ceaselessly stir sewage, but stirring sewage will then be unfavorable for particulate deposits.
Utility model content
This utility model is intended to provide a kind of flocculation basin processed for electroplating sewerage, and with while guaranteed efficiency, flocculant can be evenly distributed in sewage, and the microgranule in sewage also can fully settle.
The flocculation basin that base case of the present utility model processes for electroplating sewerage, including flocculation cell body, described flocculation cell body is surrounded by contour body of wall；Being provided with dividing wall in described flocculation basin body, flocculation cell body is divided into flocculation reaction district and settling zone by dividing wall；Being provided with connection flocculation reaction district and the relief area of settling zone on described dividing wall, setting buffers has upper end open and lower ending opening, and upper end open is positioned at flocculation reaction district, and lower ending opening is positioned at settling zone；The connection that is provided above on flocculant distributor pipe, and flocculant distributor pipe in described flocculation reaction district has flocculant conveying pipe, flocculant distributor pipe is provided with some liquid-leaking nozzles, flocculant conveying pipe is provided with valve；Being provided with water inlet on the sidewall in described flocculation reaction district, the top of described settling zone sidewall is provided with outlet；It is additionally provided with blender in described flocculation reaction district.
The principle of this programme is:
Sewage enters the flocculation reaction district of flocculation cell body through water inlet, then opens the valve on flocculant conveying pipe, and flocculant will go in flocculant distributor pipe, and flocculant can be in liquid-leaking nozzle trickles down sewage；In order to ensure that flocculant can be uniformly distributed in sewage, blender will stir sewage while adding flocculant.Interpolation flocculant is primarily to the microgranule in sewage can be gathered into floc sedimentation shape, and to contribute to the sedimentation of microgranule, but owing to being provided with blender in flocculation reaction district, therefore sewage cannot complete precipitation in flocculation reaction district；Therefore sewage will be by precipitating in inflow settling zone, relief area, owing to being provided with blender in flocculation reaction district, therefore the sewage in flocculation reaction district can produce vibration, on the one hand and dividing wall has and stops the wave of sewage in flocculation reaction district, on the other hand the sewage lower ending opening from relief area enters sedimentation tank, and owing to the hydraulic pressure of bottom is bigger, therefore the flow velocity of sewage entrance settling zone is more stable, and the impact of generation is less, i.e. relief area can avoid vibration to be delivered to settling zone；Additionally outlet is arranged on the top of settling zone sidewall, then the hydraulic pressure of water outlet is less, can avoid the formation of bigger whirlpool, and in reduction settling zone, the flowing of sewage, makes sedimentation effect more preferably.
This programme produces and provides the benefit that:
Flocculant adds as a solution, and is provided with blender, is therefore more beneficial for flocculant and is evenly distributed in sewage；And flocculation cell body is divided into flocculation tank and sedimentation tank, knowable to above-mentioned principle, the precipitation that can make sewage is more abundant；Owing to being provided with relief area, it is to avoid in flocculation reaction district, the vibration of sewage is delivered to settling zone so that define a preferable static environment in settling zone；Additionally the sewage in Sedimentation tank is while flowing into, and is also flowing out, and therefore efficiency can also be guaranteed.
Preferred version one, as the further optimization to base case, described dividing wall includes dividing wall one and dividing wall two, the height of dividing wall one is less than the height of flocculation basin walling, dividing wall two is contour with flocculation basin walling, and the bottom of the lower end of dividing wall two and flocculation cell body has gap, dividing wall one and dividing wall two and also has gap, and there is between dividing wall one and dividing wall two overlapped part, described relief area is between the part that dividing wall one and dividing wall are overlapped.
In preferred version one, owing to the length of relief area is longer, therefore can reach preferable barrier effect, preferably disperse wave, and then reduce the uneven pressure that the sewage in sedimentation tank is produced by wave；But the structure of preferred version one is complex when building.
Preferred version two, as the further optimization to base case, described dividing wall is contour with flocculation basin walling, at least one breach it is provided with on described dividing wall, being additionally provided with the C-shaped body of wall corresponding with breach on dividing wall, C-shaped body of wall upper end is contour with dividing wall, and the lower end of C-shaped body of wall has gap with the bottom of described flocculation cell body, and C-shaped body of wall up/down perforation, described relief area is between C-shaped body of wall and dividing wall；Preferred version two is compared with preferred version one, simpler when building.
Preferred version three, as the further optimization to base case, described flocculant distributor pipe is annular, and flocculant distributor pipe is fixed on the sidewall in described flocculation reaction district by pipe clamp；Flocculant distributor pipe is arranged to annular, on the one hand can extend the degree of flocculant distributor pipe, the most convenient fixing.
Preferred version four, as the further optimization to base case, is provided with multiple filtration net in described relief area；It is provided with drainage screen in relief area, on the one hand can filter that some are bigger permissible, on the other hand can also have the effect weakening wave.
