In the settling tank inclined tube can be arranged, to improve sedimentation effect.
The coagulating agent chemicals dosing plant that is connected with the influent waste water pipeline can be arranged, to make things convenient for the adding of coagulating agent.
Further, can in mixing pit, magnetic loading pond, flocculation basin, first stirrer, second stirrer and the 3rd stirrer be set respectively.To accelerate the hybrid reaction effect.
The input of material for convenience can be to the adaptive acid-alkali accommodation of mixing pit with the precipitation agent chemicals dosing plant, to the adaptive magnetic supplementing device in magnetic loading pond, to the adaptive coagulant aids throwing device of flocculation basin.
The beneficial effect of utility model is: have remarkable advantages such as floor space is little, processing efficiency is high, stable water outlet, added amount of chemical is few, sludge yield is few, dewatering performance of sludge improves.
[description of drawings]
The utility model will be further described below in conjunction with accompanying drawing.

Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1 for mixing pit, 2 for magnetic load the pond, 3 for flocculation basin, 4 for settling tank, 5 for sludge pump, 6 for the coagulating agent chemicals dosing plant, 7 for acid-alkali accommodation and precipitation agent chemicals dosing plant, 8 for magnetic supplementing device, 9 be first stirrer, 10 be second stirrer, 11 for coagulant aids throwing device, 12 be the 3rd stirrer, 13 for sludge dehydration device, 14 for cyclone separator, 15 be that effluent trough, 16 is inclined tube.
[embodiment]
Referring to accompanying drawing, a kind of heavy metal wastewater thereby coagulating sedimentation of the utility model treatment system, it is characterized in that: comprise that mixing pit 1, magnetic load pond 2, flocculation basin 3, settling tank 4, sludge pump 5 and cyclone separator 14, influent waste water pipeline connection mixing pit 1, mixing pit 1 are communicated with magnetic loading pond 2, magnetic loading pond 2 is connected with flocculation basin 3 employing overflows, flocculation basin 3 has the settling tank 4 of overflow type effluent trough 15 to be connected with sludge pump 5 entrances with settling tank 4 connections, top, sludge pump 5 outlets connect cyclone separator 14 entrances, and cyclone separator 14 outlets connect magnetic and load pond 2.
In embodiment of the present utility model, inclined tube 16 is arranged in the settling tank 4, can improve sedimentation effect.
In embodiment of the present utility model, be furnished with the coagulating agent chemicals dosing plant 6 that is connected with the influent waste water pipeline, to make things convenient for the adding of coagulating agent.
In embodiment of the present utility model, in mixing pit 1, magnetic loading pond 2, flocculation basin 3, first stirrer 9, second stirrer 10 and the 3rd stirrer 12 are set respectively.Can accelerate the hybrid reaction effect.
In embodiment of the present utility model, to mixing pit 1 adaptive acid-alkali accommodation and precipitation agent chemicals dosing plant 7, to magnetic load pond 2 adaptive magnetic supplementing devices 8, to flocculation basin 3 adaptive coagulant aids throwing devices 11.
Pending water enters mixing pit 1 after adding flocculation agent, under the effect of first stirrer 9, makes that flocculation agent and water are quick and complete to be mixed, thereby the particulate in the former water is taken off surely.Deliquescent heavy metal ion and precipitation agent generate the throw out of indissoluble in the waste water.The dynamic process of coagulation process is very short, and the water retention time of mixing pit 1 is 1～3min, enters magnetic then and loads pond 2.
Magnetic loads in the pond 2 and adds fine magnetic (particle diameter 60～100 μ m), and the stirring by second stirrer 10 makes fine magnetic mix with little flocs unit is quick and complete, thus the weight of raising flocs unit.The hydraulic detention time in this pond is 1～3min, enters flocculation basin 3.
Further form bigger flocs unit by adding coagulant aids in the flocculation basin 3, the hydraulic detention time in this pond is 6～10min, enters settling tank 4.
Settling tank 4 adopts upward flow alveolate leaning pipe precipitation, and flocculation back water enters the inclined tube bottom of settling tank 4, the inclined tube district that upwards flows through then, and flocs unit precipitates in inclined tube 16 and slides in the effect of gravity.Because the effect of magnetic, its density obviously strengthens, and flocs unit is easy to precipitation, and this has improved sedimentation effect greatly.Sludge pump 5 is transported to magnetic and mud in the cyclone separator 14, and the magnetic of separating directly is added to magnetic and loads in the pond 2.
Add magnetic in the coagulation stage, increase flco density, hold back and catch fine flco, thereby improve subsidence rate, raising effluent quality.
Chemical coagulation and precipitation technology of the present utility model is compared with traditional coagulating sedimentation technology, the processing load can be increased to 60～80m/h, and (conventional art is 4～6m/h), floor space is 1/10 of conventional art, to the transformation of sewage plant or the existing sewage plant of construction land anxiety, big meaning is arranged all.
Compare with traditional coagulation-settlement process, the utility model has following advantage: (1), heavy speed is fast, efficient is high, take up an area of less, be widely used; (2), effective: as effectively to remove COD, SS, bacterium algae, TP, heavy metal, wet goods; (3), shock-resistant, startup fast (the total system Inlet and outlet water was less than 20 minutes); (4), low, the operation province of investment; (5), sludge yield is few, easily dehydration; (6), the construction period is short, the civil engineering amount is few; (7), the integrated degree height of device, but modularization, mobile.
