Description
Technical field
The invention belongs to field of waste water treatment, specifically, design a kind of microwave oxidized waste water treatment system and method for wastewater treatment, described system is used to handle high density, biological process organic wastewater with difficult degradation thereby.
Background technology
High concentration hard-degraded organic waste water is meant that difficult degradation, biodegradability are poor, its BOD
5/ COD value is very little, usually less than 0.2, and the high organic waste water of COD height or colourity.The water yield is not very big, but pollution load is very big, adopts traditional biological process to be difficult to reach the degradation effect of expection.Its main source is industry production waste water such as papermaking, dyestuff, pharmacy, oil refining, organic synthesis, pesticide producing.The environmental system that in a single day enters into this class waste water can cause and serious consequence, often causes the irreversible lesion of environmental system.
Existing catalytic wet air oxidation is normally under high temperature (200-350 ℃), high pressure (2-20MPa), and as oxygenant, under catalyst action, organism in the oxidation removal water finally reaches the purpose of mineralising with CIO2.This abroad technical development is very fast, and the seventies in 20th century, Japan has set up the catalytic wet device in succession and handled various organic waste waters, handle ethylene production waste water washings as Nippon Mitsubishi Oil chemical company, its operational condition: 200 ℃, 3.45MPa, stopped 60 minutes, treatment capacity is 120m
3/ d, water inlet COD is 7.5-15g/L, the COD clearance is 67%-80%; Kawasaki, Japan morning sun chemical company handles propylene cyanogen factory effluent, and its operational condition: 250 ℃ of .7MPa stopped treatment capacity 790m 90 minutes
3/ d, water inlet COD is 37-46g/L, and water outlet COD is 14.8-16.1g/L, and the COD clearance is that 60%-65%. has more research report from the eighties to the nineties, and this technology is still in the research in-depth at present.The Yin Chenglong of the Du Hongzhang of Dalian Inst of Chemicophysics, Chinese Academy of Sciences etc. and Anshan Research and Design Inst., of Coking and Refractorics, Ministry of Metall etc. have delivered the result of study of handling high-concentration organic sewage difficult to degrade about catalytic wet air oxidation in 1997.Its details is seen " water technology ", Du Hongzhang, " high-concentration organic sewage difficult to degrade catalytic wet purification techniques " article of delivering in June, 1997.The principal reaction device is processed into by TA3 type titanium steel in the research, and its design pressure is 12MPa, and use temperature is less than 360 ℃. reactor inside diameter 16mm, long 500mm.The equipment that uses in the technological process has air container, tensimeter, preceding pressure controller, gas regulating valve, mass flowmeter, water gauge line etc.Handle the step of waste water: oxidant gas (air) is from steel cylinder, transfer to required pressure through preceding pressure controller, after former water mixing preheating through failing with the micro-fresh feed pump of height behind the mass flowmeter, enter reactor by reactor bottom, the upper and lower dress porcelain grain that adds in the reactor. middle dress catalyzer, the high about 7.5cm of bed, reacted material is come out by the reactor upper end, cool off, separate with separator through condenser successively, sampling analysis when liquid enters water tank, gas through after pressure-regulator and the emptying of exhaust flow meter.The optimum process condition of reaction is 270 ℃ of .9MPa, and air capacity is 6.2L/h, and the charging air speed is 2.0h-1.The weak point of this technology: (1) reaction must be carried out obtaining satisfactory result under 270 ℃, 9MPa condition; (2) costing an arm and a leg from controlling catalyst; (3) waste water directly contacts with reactor, easily the material of reactor is corroded.
Microwave is described as one of greatest invention of 20th century as a kind of hertzian wave, compares with conduction heating, microwave has that rate of heating is fast, heating efficiency is high, homogeneous heating, temperature by interior of articles to characteristics such as outside diffusions.Had in a large number and studies show that, for chemical reaction, microwave is except that having heat effect, also having non-thermal effect. the intensive vibration will be carried out to the chain-like structure of larger molecular organics in the electric field of more than one hundred million alternations of microwave per second and magnetic field, make it destroy with fracture, form small molecule structure, carry out catalyzed oxidation again, finally be decomposed into CO2 and H2O. in the last few years microwave be applied to widely in the catalytic wet oxidation field, as " the microwave catalysis oxide treatment is difficult to resolve the technology and the device of organic waste water " of Dalian University of Technology's invention, the patent No.: 02118708.8.Technology in the research comprises: grid impurity elimination, flocculating settling, catalyzed oxidation and vapor condensation.Catalyzed oxidation is to carry out in microwave reactor, and optimum process condition is: the ratio of oxygenant quality and waste water COD quality is 1.0-20%, and temperature is lower than 100 ℃, residence time 4-17min, and the waste water COD clearance is about 95%.The weak point of this technology is: (1) very easily makes the temperature of waste water reach boiling point because waste water carries out microwave radiation under normal pressure, owing to the reason of vaporizing can cause the lot of energy waste; (2) temperature of reaction can only reach 100 ℃, from chemical kinetics, chemical reaction velocity is limited to some extent.
