Description
Technical field
The present invention relates to a kind of method of utilizing the direct direct current oxidized waste water of sun power, specifically, relate to solar DC electrooxidation method for treating garbage percolation liquid.
Background technology
Percolate is a kind of organic waste water of difficult degradation of high density, and its hardly degraded organic substance, ammonia nitrogen, SS and colourity are all higher, and N∶P ratio is seriously lacked of proper care.Method for treating garbage percolation liquid is a lot of at present, can be divided into pre-treatment, main processing, advanced treatment by process.Pre-treatment has physico-chemical process, and main processing has biological method, as aerobic treatment, and anaerobic treatment, anaerobism and aerobic combination, soil processing etc., advanced treatment, has the method for physico-chemical processes and combination.Adopt traditional technology to process very difficult up to standard, with high costs, serious environment pollution after outer row, waste water reclamation rate is low, reclaims water quality inferiority, and pollutent cannot reclaim, and waste resource, easily causes secondary pollution.The present invention relates to a kind of method of utilizing the direct direct current oxidized waste water of sun power, specifically, is solar DC electrooxidation method for treating garbage percolation liquid.
The specifically galvanic generation of solar panel, the direct current that solar-electricity pole plate produces, is directly imported into oxidizing electrode, without energy storage device and current/voltage setting device.In electrolytic acid cleaning oxydation process, NH
3the oxidized removal of-N and COD.Adopting inert metal electrode is anode, percolate is carried out to advanced treatment by electrolytic process, current density hour, COD, NH in percolate
3-N can present the more than 95% of trend beginning concentration of stable degraded, substantially can directly discharge or reuse.On negative plate, can deposit the heavy metal ion in percolate simultaneously.That a kind of pollutent can be realized processing recovery completely, the novel process of water resources complete-reclaiming substantially.
Summary of the invention
1, goal of the invention
The object of the invention is to overcome the deficiencies in the prior art part, and a kind of less investment is provided, utilizes method and the technique of the direct direct current oxidized waste water of sun power.
2, technical scheme: the present invention is achieved through the following technical solutions:
The galvanic generation of solar panel: for adapting to the generation of percolate, for example, select the specification of cell panel to be generally as 2000W/18V for every 100 tons/day, according to voltage request 18V, need the series connection of 20 36 × (156 × 156 millimeters) silicon wafer.
The transmission transmission to electrode of electric current: the direct current that solar-electricity pole plate produces, is directly imported into oxidizing electrode, without energy storage device and current/voltage setting device.
The electrooxidation processing of percolate: in electrolytic acid cleaning oxydation process, NH
3the oxidized removal of-N and COD.Adopting inert metal electrode is anode, and in the time that current density is 50.0mA/cm2,12 hours COD of electrolysis remove 85%, ammonia nitrogen removal 100%.Percolate is carried out to advanced treatment by electrolytic process, current density hour, COD, NH in percolate
3-N can present the more than 95% of trend beginning concentration of stable degraded, substantially can directly discharge or reuse.
On negative plate, can deposit the heavy metal ion in percolate simultaneously.
3, advantageous effect:
The first, the direct current that solar-electricity pole plate produces, gives full play to the chronicity of solar electrical energy generation, and the technological merit of independence has solved the problem that energy consumption is high, expense is large that processing mode exists in the past.
The second, the direct current that solar-electricity pole plate produces is directly imported into oxidizing electrode, and without energy storage device and current/voltage setting device, equipment is built and move very easy, and equipment cost is extremely low.
The 3rd, due to time limitation and the energy consumption that can not consider to process, available electrolytic process is carried out advanced treatment to percolate, and current density hour, in percolate, COD, NH3-N can present the more than 95% of trend beginning concentration of stable degraded, substantially can directly discharge or reuse.
The 4th, on negative plate, can deposit the heavy metal ion in percolate simultaneously.
accompanying drawing explanation:fig. 1 is the integrated processing printed circuit board of film of the present invention copper-containing wastewater method process flow sheet.
