Description
Technical field
The utility model relates to field of sewage treatment equipment, particularly relates to a kind of tandem sewage sedimentation device.
Background technology
The environmental protection problem of China in Recent Years becomes increasingly conspicuous, and in order to Sustainable development and environmental protect, country also checks severely the waste gas discharge of wastewater of enterprise, and therefore some factories of enterprise also pay attention to environment protection gradually.
First current most enterprises factory, for the process of industrial sewage, generally can carry out many ponds precipitation to sewage and add drug precipitation, then be for further processing to oettIed sewage.General in the precipitation positions such as settling tank, setting tank or settling bath, filter screen can be provided with sewage is filtered further.
Its weak point is: the filter screen in existing settling system is fixing, along with the accumulation of precipitation position base sludge, in filter screen bottom sewage, the concentration of dirt increases gradually, dirt easily results in blockage to filter screen on the one hand, on the other hand, the small-particle dirt in sewage, because distance filter screen is excessively near, be easy to through filter screen, be mixed into the waters on filter screen upper strata.In addition, after filter screen blocks duration of service for a long time, need to change filter screen, and when changing filter screen in existing settler, need to close down whole system, resume operation again after replacing, not only lose time, also very low to the deposition efficiency of sewage.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of tandem sewage sedimentation device, and being provided with in the settlement of sewage groove of this tandem sewage sedimentation device can the filter screen of upper and lower displacement, can promote sedimentation effect; In addition this filter screen can be changed online, and without the need to the equipment of closing down, therefore the precipitation detersive efficiency of sewage is high.
Concrete technical scheme of the present utility model is: a kind of tandem sewage sedimentation device, comprise two settling baths of series connection mutually, be respectively one-level settling bath and two-stage precipitation groove, described settling bath inside is equipped with the filter screen of horizontal positioned, settling bath inside is divided into upper and lower two regions by described filter screen, be respectively be positioned at filter screen top for clear water zone and be positioned at filter screen bottom for settling region; The water-in of settling bath is located at below filter screen, the water outlet of settling bath is located at the top of settling bath sidewall, water-in and the sewage conveying tube of described one-level settling bath are connected, the water outlet of one-level settling bath is communicated with the water-in of described two-stage precipitation groove, described filter screen is connected with expansion link, described expansion link is vertically arranged, the lower end of expansion link is connected with filter screen, the upper end of expansion link is exposed to the settling bath external world through the top of settling bath, the upper end of expansion link is provided with motor, and described electric machine control expansion link band electric filter carries out upper and lower displacement.
During utility model works, sewage to enter the settling region in one-level settling bath by water-in from sewage conveying tube, sewage precipitates in settling region, and the macrobead dirt in sewage is by leaving standstill to sink gradually, and upper strata is comparatively clean sewage.Along with increasing of sewage, when wastewater level is higher than filter screen, higher than the sewage of filter screen part through the filtration of filter screen, enter clear water zone.
Along with the accumulation of settling region dirt, in sewage below filter screen, the concentration of dirt increases gradually, the upwards displacement of electric machine control expansion link band electric filter, one side like this can avoid filter screen to be blocked by dirt, on the other hand, waste concentration in the sewage below filter screen can be made lower, avoid too much small-particle dirt through filter screen, cause the water degradation of clear water zone.
When water level reaches water outlet, the sewage of clear water zone is discharged into two-stage precipitation groove from water outlet, sewage in two-stage precipitation groove after again precipitating and filtering, from water outlet discharge enter next step process.
As preferably, the aperture of the filter screen of described one-level settling bath is greater than the aperture of the filter screen of described two-stage precipitation groove.In two-stage precipitation groove, in sewage, the particle size of dirt is less than the particle size of dirt in one-level settling bath sewage, and therefore two-stage precipitation groove needs to reduce filter screen particle diameter to promote filter effect.
As preferably, the top of described two settling bath inside is equipped with filter screen for subsequent use, described filter screen for subsequent use is fixed on expansion link, described filter screen, filter screen for subsequent use and expansion link are all located by the hook being located at expansion link outer wall, described hook is positioned at the bottom of filter screen or filter screen for subsequent use, and hook is collapsible to be entered in expansion link.When filter screen to be crossed for a long time and cause sieve meshes to block duration of service, need to change filter screen, now, the hook first controlling expansion link bottom shrinks as expansion link, filter screen automatic sedimentation is low to settling bath, then the hook controlling to shrink stretches out, and makes the hook below expansion link filter screen for subsequent use shrink simultaneously, filter screen for subsequent use along expansion link landing to expansion link bottom after located by the hook of expansion link bottom, replacing completes.This process can be carried out online, and do not affect sewage disposal, efficiency is high.
As preferably, the top of described two settling baths all can be opened.Open the top of settling bath, filter screen for subsequent use can be placed and settling bath is cleared up.
As preferably, the sidewall of described two settling baths is equipped with bezel, and described bezel is provided with graduation apparatus.The setting of bezel can be convenient to the water level that staff observes sewage in settling bath, the accumulation degree of dirt, and the situation such as concentration of wastewater below filter screen, suitably control the height of filter screen according to these information, and discharge the need of carrying out cleaning to dirt.
As preferably, the sewage conveying tube before described one-level settling bath water-in is provided with reducing valve.Before sewage enters one-level settling bath, reduced pressure treatment is carried out to sewage, effectively can slow down effluent flow rate, be convenient to sewage and precipitate in settling bath.
As preferably, between the settling bath inner side-wall that described filter screen is in contact with it, be provided with sealing-ring.
As preferably, the bottom of described two settling baths is equipped with openable sewage draining exit.When dirt accumulation is too much, by sewage draining exit, dirt is cleared up.
As preferably, the sidewall described two settling baths being positioned at settling region is provided with charging opening.Before sewage enters, in settling bath, add medicament by charging opening and make settlement of sewage efficiency higher.
As preferably, described tandem sewage sedimentation device is provided with the settling bath of multiple mutual series connection.When two settling baths still cannot satisfy the demands sewage purification requirement, by increasing the quantity of settling bath, multiple settling bath series connection can improve the degree of sewage purification.
Be compared with the prior art, the beneficial effects of the utility model are: this tandem sewage sedimentation device is provided with mobilizable filter screen, can have more waste concentration in filter screen bottom sewage and upper and lower displacement, avoid filter net jam, the precipitation clean effect of lifting sewage; This filter screen can be changed during equipment running online simultaneously, and without the need to interrupting device, it is convenient to change, and efficiency is high.
