Detailed description of the invention
Below in conjunction with each embodiment shown in the drawings, the present invention is described in detail; but it should what illustrate is; these embodiments are not limitation of the present invention; those of ordinary skill in the art, according to the equivalent transformation in these embodiment institute work energy, method or structure or replacement, belong within protection scope of the present invention.
Shown in ginseng Fig. 1, Fig. 1 is the structural representation of a kind of sewage-treatment plant of the present invention, and in figure, horizontal arrow represents water inlet, and vertical arrow represents water outlet.
A kind of sewage-treatment plant, including agent set and water inlet chemicals dosing plant, is from top to bottom sequentially provided with effluent trough 1, slanting baffle 2, dynamic rete 3 and spoil disposal layer inside agent set；Spoil disposal layer is provided with cloth bucket 4, sludge out pipe 5, mud drainage slot 6 and receives bucket 7, and sludge out pipe 5 is connected with mud drainage slot 6, and mud drainage slot 6 is located at spoil disposal layer and receives the bottom of bucket 7, and cloth bucket 4 is connected with water inlet chemicals dosing plant by captation 10.
The sewage-treatment plant that the present embodiment provides, by adding flocculant, flocculation aid at water inlet chemicals dosing plant, after being sufficiently mixed, making charged surface particles in sewage be fully neutralized, grain spacing is from diminishing, under van der Waals interaction, it is closely linked between particulate matter, form stable chemical bond, making colloidal solid in sewage lose steady statue, separating from sewage thus forming flco.The flco separated, under hydraulic structure effect, rests in agent set, is set off the filter membrane (dynamic rete) gradually forming densification by waterpower.This film without support member, can continuous self renewal, the Dynamic Membrane of renewal constantly filters impurities in water, makes water outlet up to mark discharge.And old Dynamic Membrane is because losing activity, volume becomes big, it is impossible to the flow velocity thrust bearing water automatically falls in receipts bucket, and is discharged it by sludge out pipe 5, mud drainage slot 6 and external control valve door, and sludge out pipe spoil disposal relies on gravity, by Valve controlling, automatic mud removing.Whole equipment realizes coagulation, precipitation, three kinds of techniques of filtration, can continuous flow, it is not necessary to backwash technique.The water treatment procedure of this device belongs to continuous running, can coordinate operation with other equipment.This device flow process is simple, easily operates, saves floor space, it is not necessary to PLC controls operation, and equipment anti-shock ability is strong.
In the present embodiment, the size of cloth bucket 4 is determined according to the service area of device, it is ensured that cloth bucket water outlet, and waterpower diffusion area covers whole device.The thickness of dynamic rete 3 is relevant with flow condition, suspension content in water inlet.
In the present embodiment, water inlet chemicals dosing plant includes agent mixer 8 and elevator pump 9, added with flocculation aid in agent mixer 8, and is connected with captation by water-supply-pipe 11；Elevator pump 9 is connected with agent mixer 9, is used for the sewage transport (lifting) added with flocculant to agent mixer 8, and then is promoted to agent set.Flocculation aid and flocculant chemical feeding quantity are determined according to influent quality Beaker Test.The function of agent mixer 8 is to be sufficiently mixed various medicament.
In the present embodiment, agent set is cylindrical atmospheric unit.
In the present embodiment, the angle of inclination (angle with lower layer of water plane) of slanting baffle 2 is 15 °～45 °.Can effectively prevent the Dynamic Membrane broken up under water inlet instability condition from entering outlet system (effluent trough 1) with water, affect effluent quality.
In the present embodiment, mud drainage slot 6 is circular layout in spoil disposal layer and the bottom receiving bucket 7.
Below by instantiation, the technique effect of the present invention is described further.
Sewage in this example comes from the fish culture waste water of oceanarium.Being mainly characterized by: the turbidity of water is higher, SS content is high.
Process technique is: self-forming dynamic membrane technique (present invention)+sterilization process.
Medicament for matching dosage is: flocculant is 10mg/L；Flocculation aid is 0.1mg/L.
After influent quality and process, water quality is:
Sewage in this example carrys out extraction oil waste water.It is mainly characterized by: float, oil content height in former water.
Process technique is: three phase separator+oil removing surge tank+self-forming dynamic membrane technique.Flocculant is 50mg/L；Flocculation aid is 0.1mg/L.
Influent quality is:
After process, water quality is:
In this device, Dynamic Membrane formation speed is relevant with influent quality, and filter effect is relevant with the compactness extent of Dynamic Membrane, and namely medicament is relevant with the pollution combination degree in sewage.The present embodiment utilizes conventional medicament, and after being sufficiently mixed with sewage, the dynamic rete of formation can effectively adsorb various pollutant in water, controls to allow it be gathered in dynamic rete by effective waterpower, thus reaching the purpose of continuous purification water.This device can effectively remove the pollutant such as Organic substance in water, float, part petroleum-type, also can realize the quick solid-liquid separation continuous operation process of other water.Lightly, easily process, accessory is without particular/special requirement, and system is easy of integration for this device.
Provided by the invention forming the sewage-treatment plant filtering rete without supporter self, mainly for the higher system of SS content by realizing solid-liquid sharp separation after adding medicament, clearance is up to more than 99%, it may be achieved run continuously.This device relies on the internal special structure form of device and flow condition, makes sewage be internally formed dynamic rete after fully mixing with medicament.Without supporting in Dynamic Membrane inside, rely on hydraulic equilibrium to form filter course, and be suspended in the position of device lower middle.Sewage is by without after support membrane filtering layer, and water outlet will enter drainage system with collecting conduit.Whole flow process without backwash Dynamic Membrane automatically updated.The rete that activity is strong is closely knit and thick and heavy, and dirt-removing power is strong.Poor activity and deactivated rete are loose, are automatically fallen into by formation precipitate and arrange in collection system, rely on head pressure to realize being automatically drained out.Whole system is small and exquisite, flexibly, takes up an area few, and system controls and operation can realize automatization, has a characteristic that
1) non-recoil is washed, can continuous effluent.
2) because of cause specific can interrupt operation flow process, when needing next time to operate continuously, self-forming dynamic membrane generates quickly, simply, easy to control.
3) in spoil disposal process, it is not necessary to interrupt process system, can spoil disposal, on one side the control water inlet of low discharge.
4) the sludge stream voltinism discharged by this device is strong, easily and next step technique concentration.
The a series of detailed description of those listed above is only for illustrating of the feasibility embodiment of the present invention; they also are not used to limit the scope of the invention, and all should be included within protection scope of the present invention without departing from the skill of the present invention equivalent implementations made of spirit or change.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when without departing substantially from the spirit of the present invention or basic feature, it is possible to realize the present invention in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the invention rather than described above limits, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in the present invention.
