Abstract
The utility model relates to an electrocoagulation sewage treatment apparatus, which comprises a cathode inner tube and an anode outer tube which are coaxial type, wherein, the cathode inner tube is a sewage intake tube which extends into the inner side of the anode outer tube, the outer tube wall of the water intake pipe is provided with a spiral channel, the head end of the anode outer tube and the cathode inner tube are fixedly connected by an insulative sealing, and a sewage outfall is arranged between the head end of the anode outer tube and the cathode inner tube. In the process of working, sewage flows through the cathode inner tube and an annular sewage flow channel which is arranged between the cathode inner tube and the anode outer tube. Pollutants in the sewage are coagulated under the action of a positive electric field and a negative electric field, and finally, the pollutants are discharged into a sedimentation tank from the sewage outfall. The utility model has the advantages of sewage treatment time reduction, treating capacity increase, running cost reduction and low cost of equipment.
Description
The utility model belongs to the equipment that the electrocoagulation method is disposed of sewage of using.
Charged ion or other charge species with after the particle of oppositely charged combines, will become unstable in water, thereby produce suspended substance or throw out.Electrocoagulation is exactly the ion that adds oppositely charged in sink drainage, make pollutent in the water such as heavy metal ion and inorganic or organic colloid instability and a kind of sewage water treatment method of coagulative precipitation, employed electrode substance can be iron, aluminium, antimony, graphite etc.The electrocoagulation method is of wide application, and contains Pb except being used for handling

-1Outside anionic general waste water, can also very handle suspensoid effectively, comprise tripoli, carbon black, clay, grease, resin, pitch, bacterium and organism, simultaneously, the electrocoagulation method can be removed 95%～99% heavy metal and other pollutent effectively.On the other hand, compare with present widely used chemical precipitation method, the processing costs of electrocoagulation method only reaches 1/2 of chemical precipitation method, and does not produce harmful wastes such as a large amount of mud, metal hydroxides.Thereby, bring into use the electrocoagulation method to dispose of sewage abroad over nearly 2 years.But the equipment that the external at present electrocoagulation method of using is disposed of sewage is that (positive and negative electrode is corresponding for the employing parallel plate, sewage flows through from two interpolars), or big tubule (sewage flows through between pipe), these device sewage loads are little, operating time is long, current consumption is big, invest also big, thereby hindered applying of electrocoagulation.
The purpose of this utility model is to propose a kind of sewage load that helps improving, and shortens the novel electrocoagulation waste disposal plant in treatment time.
The utility model is by the following technical solutions: device comprises into pipe and anode outer tube in the negative electrode of coaxial shape, has enough wide annular sewage runner between pipe and the anode outer tube in the negative electrode, the tail end of its anode outer tube is a blind end, pipe is sewage water inlet pipe in the negative electrode, its as the end mouth of pipe of water-in outside anode outer tube head end, the another port then reaches the position that has with a certain distance from anode outer tube tail end, so that sewage can be as the criterion by smooth clockwise annular sewage runner between the inflow inner and outer pipes after flowing out from this port.Pipe stretches into the part in the anode outer tube in the negative electrode, and its outer wall has the spiral-shaped groove road, has insulativity to be sealedly and fixedly connected between the pipe in the head end of anode outer tube and the negative electrode, and the position has outfall near anode outer tube head end.
This device is performed such sewage disposal: sewage is pumped in the negative electrode by pump and manages, the sewage Continuous Flow is crossed the interior pipe of negative electrode of electronegative pressure, in sewage, form uniform galvanic current, sewage is after pipe flows out in the negative electrode, annular sewage runner in anode outer tube tail end turns to the inflow negative electrode between pipe and the anode outer tube, because the outer wall of pipe has the volution conduit in the negative electrode, can form sufficient surface with tube wall when sewage is flowed and contact also turbulization between inner and outer pipes, promote mass transfer.After sewage was subjected to positive and negative effect of electric field in succession, its pollutent became unstable and condenses, and enters settling tank from outfall at last, thereby finishes sewage treatment process.
Volution conduit on the negative electrode outer wall of inner tube of the present utility model can be shaped by machining shaping of anticathode outer wall of inner tube or direct pouring, also can install the member formation that the volution fin maybe can form the volution conduit on the negative electrode outer wall of inner tube.
For being maintained fixed the mutual structure between the inner and outer pipes and keeping its proper alignment, between inner and outer pipes, be provided with the insulativity resting support and do to support fixing inner and outer pipes.
Anode outer tube tail end of the present utility model can adopt helical flange lid sealing, the head end of anode outer tube then with the helical flange cover to making the insulativity sealing and fixing between the inner and outer pipes so that install, dismounting and maintenance.
The utility model can use short sewage disposal pipe, thereby can shorten the time for the treatment of processes, improves treatment capacity, and capable of reducing energy consumption, saves the operation working cost, and the capital investment of equipment is also lower.The utility model is disposed of sewage, and the clearance of its heavy metal and other pollutent can reach 95%～99%.
Below in conjunction with accompanying drawing in detail CONSTRUCTED SPECIFICATION of the present utility model is described in detail:
Fig. 1 is the structural representation of device;
Fig. 2 is the topology view of pipe racks spiral fluted outer wall in the negative electrode.
As shown in Figure 1,1 is as pipe (its mouth of pipe position is provided with direct current cathode connection port) in the negative electrode of sewage water inlet pipe, 3 for becoming the anode outer tube of coaxial shape with pipe in the negative electrode, the head end of anode outer tube overlaps in 2 anticathodes with helical flange that to make insulated enclosure between pipe and the anode outer tube fixedly connected, its tail end seals with helical flange lid 5, the outer wall that stretches into tube portion in the negative electrode in the anode outer tube has spiral channel (as shown in Figure 2), pipe caudal part position has resting support (4) its supporting to be fixed on the inwall of anode outer tube in the negative electrode, outfall (6) is opened at anode outer tube head end upper tube wall, is provided with the anode connection port in the bottom of relief outlet.The direction of arrow is the drainage flow direction among Fig. 1.
