Description
Technical field
The present invention relates to the coagulating equipment in a kind of sewage physicochemical processing, a kind of control coagulating equipment that medicine adds more than two kinds that has of more specifically saying so belongs to the environmental protection equipment technical field.
Technical background
The object of the materialization Coagulation with Treatment of sewage mainly is small suspended substance and the colloidal impurity in the sewage.Traditional coagulation reactor all adopts reactor (groove, jar or pond) basically, once adds pharmacy response, reacts by mechanical stirring, and this coagulation reactor has numerous bibliographical informations, does not do concrete expansion here.
In improvement to coagulation reactor, be to carry out mostly at the mixed performance aspect of medicament in the reactor (groove, jar or pond) and sewage, the settling vessel of this patent documentation report is provided with texture improvement such as a plurality of swash plates by being provided with a courage, settling vessel between line mixer and the settling vessel housing in the tube courage as State Intellectual Property Office's on March 7th, 2007 disclosed " a kind of settling vessel ", blended route and time have been prolonged, make the mixing of water and medicament more abundant, further improve sedimentation effect.But above-mentioned coagulation reactor still has the following disadvantages: floor space is big, dosing is wayward, be difficult to realize that the hybrid reaction efficient of interpolation, medicament and the sewage of various medicaments still awaits further raising etc.
Summary of the invention
At above-mentioned situation, the problem that quasi-solution of the present invention is determined provide a kind of simple in structure, floor space is little, dosing is controlled easily, can realize the coagulation reactor of the sewage disposal that the hybrid reaction efficient of interpolation, medicament and sewage of various medicaments is high.It can give full play to the reaction mechanism and the effect of medicament, realizes segmentation substep dosing control.
For achieving the above object, the present invention is by the following technical solutions: a kind of coagulation reactor that is used for sewage disposal, it comprises mutual pipe connection inlet segment, conversion zone and water exit end, and described inlet segment comprises water inlet pipe, with the sewage liquid feeding pump of described water inlet pipe pipe connection; Described water exit end comprises rising pipe; Described inlet segment also comprises and described water inlet pipe pipe connection magnetic flow meter; Described conversion zone comprises the simply connected mixing reactor more than two, and described simply connected mixing reactor comprises hybrid reaction pipe and chemicals dosing plant, is provided with the mixing vane in the pipeline of described hybrid reaction pipe; Described chemicals dosing plant comprises the main feed liquor arm that is communicated with the hybrid reaction pipe; Pipe connection between the described simply connected mixing reactor.
Also be connected to vacuum breaker on the water inlet pipe of described inlet segment.Pipe connection is between the described simply connected mixing reactor: pass through " U " shape pipe connecting and " J " shape pipe connecting pipe connection between the adjacent hybrid reaction pipe.Described chemicals dosing plant also comprises auxiliary feed liquor arm, and described auxiliary feed liquor arm is communicated with the hybrid reaction pipe.The main feed liquor arm of described chemicals dosing plant is provided with is responsible for vacuum breaker and gauger.The auxiliary feed liquor arm of described chemicals dosing plant is provided with auxilliary pipe vacuum breaker and auxilliary pipe ball valve.Be provided with more than two in the pipeline of described hybrid reaction pipe and mix vane, described mixing vane comprises left-handed mixing vane and dextrorotation mixing vane.
Adopt such scheme, the flow that pending sewage is controlled with under meter by the sewage liquid feeding pump pumps into (flow can be controlled according to the water yield and requirements in water quality), and sewage enters first simply connected mixing reactor.The medicament metering of various participation coagulatings such as different coagulating agent, coagulation synergistic agent, flco coagulant aids, acid-base modifier is sent in the hybrid reaction pipe, reacted.On the one hand because the present invention has the simply connected mixing reactor more than two, can be according to the actual features of sewage and reaction mechanism, the reaction front and back order of medicine, in the hybrid reaction pipe of different simply connected mixing reactors, add pointed medicament, simultaneously, because chemicals dosing plant also comprises auxiliary feed liquor arm setting, also can add two kinds of confections respectively on same simply connected mixing reactor; On the other hand, owing to be provided with the mixing vane in the pipeline of hybrid reaction pipe, medicament and sewage stir and the effect of current strong disturbance by means of the violent eddy flow that mixes vane, make medicine in sewage even spread and with mix.In addition owing to pass through " U " shape pipe connecting and " J " shape pipe connecting pipe connection between the adjacent hybrid reaction pipe, make hybrid reaction pipe Chinese traditional medicine in sewage fast behind the uniform mixing, mixed solution is at U " flow steadily in shape pipe connecting and " J " shape pipe connecting; help the formation of flco, make water outlet reach the requirement of solid-liquid separation at last.In a word, the coagulation reactor that is used for sewage disposal of the present invention, have simple in structure, floor space is little, dosing is controlled easily, can realize the hybrid reaction efficient advantages of higher of interpolation, medicament and the sewage of various medicaments.It can give full play to the reaction mechanism and the effect of medicament, realizes segmentation substep dosing control.
At the sewage of matching stain production discharging, its CODcr concentration is 13000mg/L, 10000 times of colourities (dilution is tree doubly).Adopt the coagulation reactor (tetrad mixing reactor) that is used for sewage disposal of the present invention, compare, cooperate corresponding same prescription medicament as follows the test-results of sewage disposal with traditional coagulating groove:
| Treatment facility | COD(mg/L) | BOD(mg/L) | B/C | pH | Colourity (doubly) |
| Former water before handling | 13000 | 1600 | 0.12 | 4.8 | 10000 |
| Tradition coagulating groove | 9170 | 1360 | 0.15 | 7.4 | 8500 |
| The tetrad mixing reactor | 5560 | 2150 | 0.39 | 8.5 | 2500 |
By data in the table as seen, the CODcr clearance of sewage is 29.46% behind traditional reactive tank coagulation with fixed attention, chroma removal rate is 34.62%, and adopting the CODcr clearance that is used for the coagulation reactor of sewage disposal of the present invention is 57.23%, and chroma removal rate is 80.71%.
