Besides, an insulated exchange membrane is arranged in the tank and divides the tank into an oxidization chamber and a reduction chamber, the tank is provided with a water inlet, an anode access, a water outlet and a cathode access, the water inlet and the cathode access are arranged on one side of the tank with the reduction chamber, the water outlet and the anode access are arranged on one side of tank with the oxidation chamber, and the cathode and the anode are respectively arranged in the cathode access and the anode access. Concentrated liquid is subjected to reduction and oxidization by the treatment device for concentrated liquid of landfill leachate and then returns to a biochemical treatment stage, and accordingly the treatment device cannot pollute environments or damage a refuse disposal system.
Description
Technical field
The utility model relates to a kind of concentrated solution treatment unit of percolate, specifically is used for remaining concentrated solution behind the consumer waste infiltration liquid membrane filtration is handled.
Background technology
At present, domestic garbage leachate treatment process mainly contains two kinds, and a kind of is microbiological treatment+membrane filtration, and another kind of treatment process is sand filtration+secondary filter+membrane filtration.The concentrated solution of the percolate that produces behind the membrane filtration has following characteristics: (1) concentrated solution output is big, duration of service half a year with the concentrated solution output of interior new film the chances are 10～15% of flooding quantity, use the output of concentrated solution of above film half a year the chances are 20% of flooding quantity, along with the film increase of duration of service, this amount also can increase.(2) COD is higher in the concentrated solution, and the content of COD is between 50000～150000mg/L generally speaking, and main component is the difficult degradation composition.(3) biodegradability is poor, because the organism in the concentrated solution mainly is the difficult degradation composition, being difficult to provides nutrition source to microorganism.(4) has very big stink.
At present, be that concentrated solution directly is back to refuse landfill for the processing of the concentrated solution that obtains behind the membrane filtration, or concentrated solution collected and evaporation or burn after simple process, but these all can't carry out not only environmental protection but also effectively handle concentrated solution.Therefore, develop that concentrated solution to percolate carries out not only environmental protection but also effectively treatment process and treatment unit are the problems that whole refuse treatment industry needs to be resolved hurrily.
Summary of the invention
The purpose of this utility model provides a kind of treatment unit of concentrated solution of percolate, uses this device can adopt the method for reduction-oxidation that concentrated solution is effectively handled, and has reduced the discharging of pollutent.
Realize that the technical scheme that the utility model above-mentioned purpose is adopted is:
A kind of concentrated solution treatment unit of percolate, at least comprise casing, power supply and anode that is connected with power supply and negative electrode, be provided with the insulating exchange membrane in the casing, exchange membrane is divided into oxidizing chamber and reduction chamber with casing, casing is provided with water-in, anode access port, water outlet and negative electrode access port, water-in and negative electrode access port are positioned on the casing of reduction chamber one side, water outlet and anode access port are positioned on the casing of oxidizing chamber one side, and negative electrode and anode lay respectively in negative electrode access port and the anode access port.
Casing is a rectangular parallelepiped, and half one is respectively reduction chamber and oxidizing chamber about rectangular parallelepiped, and anode access port and negative electrode access port all are positioned at the top of rectangular parallelepiped casing, and water-in and water outlet are positioned at the side of rectangular parallelepiped casing; The center, bottom of casing is provided with sewage draining exit, and sewage draining exit all is communicated with reduction chamber and oxidizing chamber; Be provided with the intermediate plate that is used for fixing exchange membrane in the casing; The bottom of casing is provided with four feets.
The concentrated solution treatment unit of the percolate that the utility model provides is provided with reduction chamber and oxidizing chamber, and it is indoor that negative electrode is positioned at reduction, and anode is positioned at oxidizing chamber, and is simple in structure, with low cost.The concentrated solution of percolate enters the reduction chamber by water-in, indoor being reduced of reduction, broken original electronic cloud structure, polarization offset takes place, enter in the oxidizing chamber by exchange membrane then, oxidized in oxidizing chamber, concentrated solution wherein difficult degradation component content after reduction-oxidation reduces, and the ratio of BOD greatly improves among the COD.The concentrated solution treatment unit of this percolate can not discharge pollutants, environmentally-friendly sanitary, stable practical.
