Technical field
The utility model relates to a kind of wastewater treatment equipment, is specifically related to the physical chemistry wastewater treatment equipment that a kind of little electrolysis combines with catalyzed oxidation.
Background technology
Iron carbon method is that multiple physics, chemical actions such as a kind of current collection is separated, coagulation, electricity flocculation, absorption are in the method for wastewater treatment of one.Its ultimate principle is to form the electrochemical techniques that countless small galvanic cells are handled waste water through corrosion effect in electrolyte solution.
Handle in the waste water process in iron carbon method, with organic waste water by the bed of iron filings and gac (1: 1 volume ratio) is housed, owing to contain and produced various small galvanic cells between tart waste water and the iron carbon, in slant acidity solution, the nascent state H that electrode reaction produced has higher activity, can carry out DeR with the tensio-active agent that contains in the waste water.On the lower anode of electropotential, iron loses electronics and generates Fe
2+Enter in the solution, make stream of electrons to carbon cathode.Consequent nascent state Fe
2+Also have very high activity,, thereby promote the galvanic corrosion of iron, make a large amount of Fe on the one hand in order to overcoming the anodic polarized action
2+Enter solution and form flocculation agent, these flocculation agent have higher absorption coagulation activity, can remove the organism and the colloidalmaterial of the change structure that produces in electric field effectively, thereby reach the removal effect to waste water COD.In the iron carbon reactor, add oxygenant on the other hand, utilize the oxidizing reaction of the ferrous ion catalysis peroxidation agent that produces in the iron carbon reaction process.The synergistic effect of little electrolysis and catalyzed oxidation want high more than the stack of each individual effect, and the consumption of oxygenant reduces greatly.Oxidant content that uses in this reactor and the weight ratio of COD can descend 20～80%.Simultaneously, the clearance of COD can reach 50～80%.It is relevant with the original concentration of COD that this removes efficient.
The applicant has applied for that to Patent Office of State Intellectual Property Office name is called " horizontal little catalytic and oxidative electrolysis technology reactor " utility model patent November 27 calendar year 2001, and this patent was authorized by bulletin on October 2nd, 2002, and the patent No. is ZL01272553.6.The structure of the horizontal little catalytic and oxidative electrolysis technology reactor of this patent as shown in Figure 1, there is dividing plate to be divided into 3～6 cavitys in the middle of the reactor, interior dress iron carbon mixture is the filler of main component, waste water enters reactor by reactor one side water-in, oxygenant has volume pump to squeeze in the reactor, catalytic oxidation takes place in reactor, with the organic matter degradation in the waste water.For improving reaction efficiency and preventing that reactor from being stopped up by filler, on this reactor, whipping appts is installed.Although this patent is compared the processing efficiency that has improved COD with iron carbon reactor in the past, and have that iron carbon does not lump, characteristics such as not stratified.But still have the following disadvantages in actual applications:
1, owing to the housing of reactor vessel is fixed, iron carbon filler in the container relies on the whipping appts drive to roll, and the iron carbon filler becomes very hard (condensing) in use for some time, and resistance is very big when therefore stirring, cause the damage of mechanical driving part and sealing member easily, reduce work-ing life.For whipping appts is run well, in the reactor filler can only install reactor volume 1/2nd in, greatly reduce the processing efficiency of reactor.
2, less because of filler in the reactor, the current short circuit phenomenon is serious, and oxygenant fails fully to react with pollutent, wastes more serious.
