To derive from pharmacy, industrial tanning, pigment production, household electrical appliances are made, automobile phosphorized electrocoating, the washing process etc. of plating, if without place
Reason, which enters environment, can produce great harm.The chromium that human body utilizes is typically trivalent, it is a large amount of take in Cr VIs can bring it is carcinogenic,
Cr VI is classified as preceding 20 priority monitorings by the harmful effects such as mutagenesis, Disease Control and Prevention Center of U.S. harmful toxic matter and disease registration administration
One of material.The contaminated wastewater scope of phenol is wide, and harmfulness is big, if without handling any discharge, to human body, fish and
Crops have serious harm.People quotes for a long time can cause headache, fatigue, insomnia, tinnitus, anaemia and nerve by the water of phenol pollution
System condition.Heavy metal in waste water can not degrade, and morphologic change or transfer can only occur, rich by aquatile or crops
Collection, and be detrimental to health by food chain, or Drinking Water for Residents is directly polluted, cause slow poisoning, trigger cancer, increase dead
Die the serious consequences such as rate；A large amount of difficult degradations, poisonous organic matter, which enter water body and can consume dissolved oxygen, makes water quality deterioration, is unfavorable for water
Raw biological existence, and the environment influence and ecological hazard of severe persistent can be caused.The place of China's heavy metal organic wastewater at present
Reason technology is limited, and traditional processing method complex procedures, operating cost are high, therefore finds an a kind of efficient, low energy consumption processing huge sum of money
The method for belonging to organic wastewater is significant.
Bioelectrochemical system is that a kind of biocatalyst i.e. microorganism is aoxidized or the electricity of reduction reaction on electrode
Chemical system.Electricity-producing microorganism oxidation of organic compounds in this bioelectrochemical system discharges electron transmission to anode, and anode
Phenol mineralising from medial compartment is CO by microorganism2, Cr in catholyte6+Receive the electronics from anode be reduced to toxicity compared with
Low Cr3+。
The processing method of the phenolic waste water containing chromium has：(1) conventional process method：Chemical precipitation method, Bubble-floating Method, physisorphtion；
(2) biomembrance process and electrolysis；(3) electro-biometric membrane compound technology；Anaerobic organism can have effectively in degrading waste water in difficult degradation
Machine thing, have the characteristics that cost is low and has a wide range of application, and electrolysis can remove most of heavy metal ion, by bioanalysis with
Both electrolysis, which combine processing phenolic waste water containing chromium, to avoid heavy metal from being adsorbed by biomembrane.The present invention uses three cell structures,
By the biomembrane in the certain microbial biomass of anode culture, suitable catholyte is selected, adds finite concentration potassium bichromate, phenol
Phenolic waste water containing chromium with the simulation of sodium chloride mixed liquor is in medial compartment, it is determined that rational hydraulic detention time, is contained with effective removal
Chromium phenolic waste water.
The content of the invention
The present invention is to will focus on the microorganism desalination of field of seawater desalination first using phenolic waste water containing chromium as research object
Pond applies to the processing of the phenolic waste water containing chromium, by selecting suitable catholyte, adds finite concentration potassium bichromate, phenol and chlorine
Change the phenolic waste water containing chromium of sodium mixed liquor simulation, it is determined that rational hydraulic detention time, with effective removal phenolic waste water containing chromium.
The device that bioelectrochemical system removes the phenolic waste water containing chromium is to be respectively by anode chamber, medial compartment and cathode chamber
4*4*3cm3、4*4*1cm3、4*4*3cm3Lucite cuboid three is in series, and anode chamber is using sanitary sewage as inoculation liquid
And biomembrane of the 1g/L anhydrous sodium acetate for cultivating certain microbial biomass is added, medial compartment adds finite concentration dichromic acid
The phenolic waste water containing chromium of potassium, phenol and the simulation of sodium chloride mixed liquor, cathode chamber are made using pH=7 50mM phosphate buffer solutions
For catholyte, the reactor is placed in insulating box and cultivated.The phenolic waste water containing chromium of medial compartment simulation is in electric field and concentration gradient
Collective effect under, it by anode microbial mineralization is CO that phenol migrates to anode2, while Cr6+To cathodic migration and final electric
Son is reduced to Cr3+.The present apparatus is three Room reactors, and anode chamber and medial compartment are with anion-exchange membrane interval, cathode chamber and centre
With cation-exchange membrane interval, reactor external resistance is 1000 Ω for room.The anode electrode material of reactor is carbon brush, cathode electrode
Material is platinum-carrying carbon cloth, therefore outside by electron transmission shape by ion transport to cathode reactor Inner Constitution one in anode
Into loop.
Anode and negative electrode are located at anode chamber and cathode chamber respectively, and the anode of reaction system is by being attached with the carbon of electricity-producing microorganism
Brush composition, negative electrode is made up of platinum-carrying carbon cloth has no microorganism attachment, and negative and positive die opening is between 1-5cm.
In 200mg/L K2Cr2O7、100mg/L C6H6O, the condition of phenolic waste water containing chromium of 4g/L NaCl mixed liquors simulation
Under, select suitable catholyte so that the Cr in phenolic waste water containing chromium6+It is efficiently removed, while does not influence the production of the system again
Electrical property, Cr at the end of periodic duty6+Clearance is up to 99.9%, and the clearance of phenol is up to 100%.
In 200mg/L K2Cr2O7、100mg/L C6H6O, the condition of phenolic waste water containing chromium of 4g/L NaCl mixed liquors simulation
Under, suitable catholyte is selected, current density peaking in 4h is 0.64A/m2。
Using pH=7 50mM phosphate buffer solutions as catholyte when, hydraulic detention time 72h, the system is most
