Description
Technical Field
The utility model relates to a waste water treatment process especially relates to a processing system that high difficult degradation organic matter waste water discharged fully up to standard.
Background
The treatment of high-difficulty organic wastewater is a problem in the current domestic and foreign wastewater treatment, and the 'difficult degradation' means that the biochemical property of the wastewater is low, the BOD5/COD value is generally below 0.3 or even lower, the wastewater is difficult to biodegrade, the COD of biochemical effluent is still 1000 mg/L-30000 mg/L, and the organic substances in the condition have toxic and harmful substances such as polycyclic aromatic hydrocarbon, heterocyclic ring and long-chain alkane or heterocyclic compounds containing nitrogen, oxygen and sulfur, oil, ammonia nitrogen and the like. The high-difficulty organic wastewater is generated in typical industries such as petrifaction, coal chemical industry, printing and dyeing, pharmacy, chemical industry, light industry, pesticide and the like. With the gradual improvement of the zero emission requirement of wastewater in China, various enterprises discharging refractory organic wastewater face severe challenges, and how to realize the treatment of refractory wastewater in an environment-friendly, economic and efficient manner is urgent.
The method for treating the organic wastewater difficult to degrade mainly adopts a physical-chemical method and a biochemical method, and each method and process still have certain disadvantages. The traditional activated sludge method and the anaerobic process can effectively decompose organic matter points in the treatment of the organic wastewater difficult to degrade, but the anaerobic process is found to be difficult to treat some organic matters in practical engineering, but the occupied area is up to, the treatment time is long, the treatment load is low, and the COD of the effluent is difficult to reach the standard. The coagulating sedimentation method in the physical and chemical method has good effect on removing organic pollutants difficult to degrade and the chromaticity of wastewater, but the method mainly transfers the pollutants in the water to flocs and sludge, does not realize complete degradation and still causes great harm to the environment. The advanced oxidation method comprises a Fenton method, a photocatalytic oxidation method, a wet oxidation method, an ozone oxidation method and the like, has the advantages of high chemical reaction efficiency, good pollutant degradation effect, small occupied area and the like, and has the defects of high treatment cost and easy secondary pollution caused by certain processes, such as the Fenton method which generates a large amount of sludge. Among them, the reason why the wet oxidation treatment cost is high is that the concentration of organic matter is low, the heat generated by oxidation is not enough to maintain the heat required by the process, and a large amount of external heat supply is required. The membrane separation technology can efficiently separate pollutants in water, such as particles, macromolecular organic matters, salts and the like in water, is the most common technical means for recycling and treating sewage at home and abroad at present, but the membrane separation method is only the concentration of the pollutants and cannot achieve the digestion of the pollutants. The patent with the application number of CN201610309671.5 proposes a technology for treating high-difficulty organic wastewater, which adopts anaerobic and aerobic biochemical treatment and then uses an MBR membrane for filtration, but the technology can not completely eliminate pollutants, and most organic matters are still concentrated in the MBR membrane.
