Abstract
A horizontal micro-electrolysis catalytic oxidative reactor belongs to a physicochemical treatment equipment for the degradation or removal of organic matter in wastewater. The internal cavity of the reactor is divided into multiple iron-carbon mixed-beds in transverse interphase by separators [5]. The top of each mixed-bed is provided with a feed inlet [2], and the bottom is provided with an outlet [9]. The mixture of iron and carbon [21] is filled in the mixed-beds. Each mixed-bed communicates in turn at the diagonal position to form a bending water channel with baffles up and down. An agitator, an aeration device and a chemical feeder device [24] are arranged on the vessel. An agitating shaft [4] of the agitator, which is provided with blades, crosses each mixed-bed. One end of the agitating shaft [4] is connected with an electromotor [7] by a reducer [6]. The aeration device gets to the bottom of each mixed-bed and the chemical feeder device is arranged on the pipeline of a water inlet [13].

The removal rate of COD can reach 50-85 percent. The agitator and the aeration device in the reactor have the advantages of no caking and no stratification of the iron-carbon.
Description
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
Wastewater treatment is the problem that environmental protection industry (epi) is paid close attention to always.In the prior art, the iron carbon reactor principle of work that micro-electrolysis device adopts is: utilize electrochemical techniques to form countless small galvanic cells through corrosion effect in electrolyte solution and handle waste water, it 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.Be by the bed of iron filings and gac (1: 1 volume ratio) is housed furtherly with organic waste water, 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, in order to overcoming the anodic polarized action, thereby promote the galvanic corrosion of iron, make a large amount of Fe
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.Through the processing of iron carbon method, the COD clearance in the waste water is about about 35%, and sometimes up to 50%, it is relevant with the original concentration of COD that this removes efficient.
Traditional iron carbon reactor structure, see shown in the accompanying drawing 2, whole cylindrical shell 23 is separated into three sections beds by sieve plate 22, water-in is located at the bottom of cylindrical shell 23, and water outlet is located at the top of cylindrical shell 23, and a side of each bed is provided with charging opening 2, opposite side is provided with discharge port 9, fill iron carbon mixture 21 in every bed in the cylindrical shell 23, because action of gravity carbon granules 20 is bigger at the upper strata proportion, iron filings are big at lower floor's proportion.Waste water enters in the iron carbon reactor from the lower end water-in during work, flows out from the upper end water outlet, and the current general direction is angled straight lines from bottom to top, sees shown in Figure 2.The deficiency of conventional iron carbon reactor is: 1, the current in the reactor substantially linearly move, and have certain short flow phenomenon, and this phenomenon directly influences the treatment effect of waste water.2, because the proportion difference of iron carbon under the effect of current, has demixing phenomenon, and be specially: the bottom is the mixture based on iron, and top is the mixture based on carbon, and the contact surface between the iron carbon is little, be unfavorable for reaction.3, the iron carbon mixture ubiquity caking phenomenon of filling in the iron carbon reactor directly influences little electrolysis and efficient.4, owing to layering of iron carbon and caking phenomenon, the working efficiency of reactor obviously descends in time, even loses efficacy.In a word, facts have proved that structurally there are many defectives really in the conventional iron carbon reactor, and these defectives cause the why immediate cause of low, the weak effect of efficient of conventional iron carbon reactor exactly, simultaneously, also expose in the past in utilization iron carbon method and handle the problem that exists aspect the waste water.For this reason, the utility model in conjunction with the catalyzed oxidation effect, has visualized a kind of novel iron carbon reactor structure from the angle of improving iron carbon reactor structure, to overcome above-mentioned deficiency, improves water treatment effect.
