Description
Technical field
The utility model relates to a kind of wastewater treatment equipment, relates in particular to the treatment unit that removes waste water middle and high concentration ammonia nitrogen.
Background technology
Give off a large amount of high-concentration ammonia nitrogenous wastewaters in the industries such as Coal Chemical Industry, pharmacy, coking, oil refining, these waste water complicated components, be difficult to biochemical degradation, hazardness is big, particularly ammonia nitrogen wherein is difficult to remove up to standard especially, becomes and administers the key difficult problem of waste water.
At present, it is that pH value with waste water is adjusted to more than 11 that traditional stripping tower removes ammonia nitrogen, bubbling air or steam in packing tower then, by gas-to-liquid contact with the free ammonia stripping in the waste water to atmosphere or steam, make ammonia nitrogen transfer to gas phase from liquid phase, adopt stripping tower that pH is had relatively high expectations, it is big to add alkali number, power consumption is big, the ammonia nitrogen removal frank temperature influence is bigger, also must combine through residue ammonia nitrogen concentration in the waste water behind the secondary stripping and just can reach qualified discharge with biological denitrification process, thereby the pre-treatment that can only handle as high-concentration ammonia nitrogenous wastewater, moreover in the stripping process because vapour-liquid ratio big (being everlasting more than the 3000:1), the ammonia that emits is because concentration is lower, absorb difficulty, be discharged in the atmosphere and can cause secondary pollution.
Therefore, the Treatment of Industrial Water device of existing ammonia nitrogen removal will expend a large amount of medicaments and the energy, only suitable lower concentration or ammonia nitrogen waste water processing on a small scale, equipment complex and expensive.Under present technical qualification, even current state-of-the-art anaerobe denitrification process and equipment, its upper limit of handling ammonia nitrogen also only reaches 1000mg/L, nitric efficiency only about 50%, and for most of nitrogenous trade effluents, ammonia nitrogen concentration is all considerably beyond 1000mg/L in its waste water.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and the high-concentration ammonia nitrogenous wastewater that a kind of equipment is simple, easy and simple to handle, processing cost is low and denitrification effect is good treatment unit is provided.
The technical solution adopted in the utility model is: agent structure is a tower body, tower body cover head central position is provided with vent passages, the tower body inner chamber is along being interval with the multilayer column plate on the short transverse, the hollow formation gas passage of column plate intermediary, gas passage connection vent passages; Be equipped with boring aeration pipe on every layer of column plate, the vent-pipe of the protruding tower body of boring aeration pipe coupling is provided with overflow plate and baffle plate in the feed-water end position of column plate, is circular waste water tunnel and scum dredger between baffle plate and overflow plate; Each overflow plate all connects motor by the interlock axostylus axostyle.
The utility model when total vapour-liquid ratio reduces, has greatly been strengthened the aeration rate on the column plate than traditional stripping tower, has increased gas-liquid mass transfer efficient.Handle greater than the high-concentration ammonia nitrogenous wastewater of 1000～50000mg/L for ammonia nitrogen concentration, nitric efficiency can reach more than 99%, both reduced running cost and power consumption, improved treatment capacity again, and be particularly useful for industry high-concentration ammonia nitrogenous wastewaters such as Coal Chemical Industry, pharmacy, coking, oil refining and handle.Have handle convenient, treatment scale is big, handling property is stable, nitric efficiency is high, suitable waste water quality and advantage such as both economical.

Fig. 2 is the vertical view of column plate 5 among Fig. 1;
Among the figure: 1. vent-pipe; 2. water inlet enters the mouth; 3. motor; 4. vent passages; 5. column plate; 6. channel-section steel; 7. interlock axostylus axostyle; 8. overflow plate; 9. baffle plate; 10. water outlet; 11. tower body; 12. high pressure spray nozzle; 13. liquidometer; 14. boring aeration pipe; 15. bubble trap; 17. circular waste water tunnel; 18. gas passage.
Embodiment
As shown in Figure 1, agent structure of the present utility model is the tower body of being made by carbon steel 11, fixedlys connected with bottom (head) with cover head with the bottom and seal in the top of tower body 11.A water inlet inlet 2 is set on tower body 11 cover heads, and water inlet inlet 2 bottoms are provided with high pressure spray nozzle 12, and waste water enters the back from water inlet inlet 2 and is sprayed in the tower body 11 by high pressure spray nozzle 12.A liquidometer 13 is installed in tower body 11 bottoms.On tower body 11 bottom (head)s, have the water outlet 10 of a treating water, the rising pipe that stretches out outside the tower body 11 is installed at water outlet 10 places.In the cover head central position vent passages 4 is set, the atmosphere that vent passages 4 is communicated with outside the tower body 11.Tower body 11 inner chambers are along being provided with multilayer column plate 5 at interval on the short transverse, and the centre of column plate 5 is hollow, forms gas passage 18, and gas passage 18 directly is communicated with vent passages 4.Fixedly connected channel-section steel 6 between every layer of column plate 5, channel-section steel 6 is fixedly connected on the column plate 5.
As shown in Figure 2, boring aeration pipe 14 is set all on every layer of column plate 5, boring aeration pipe 14 connects vent-pipes 1, and vent-pipe 1 from inside to outside stretches out tower body 11, and air outside is transported to boring aeration pipe 14 on every layer of column plate 5 by gas blower by vent-pipe 1.Be provided with overflow plate 8 and baffle plate 9 in the feed-water end position of column plate 5, overflow plate 8 and the baffle plate 9 30～50cm of being separated by each other, and baffle plate 9 is than overflow plate 8 high 40～50cm.Circular waste water tunnel 17 and scum dredger 15 are arranged between baffle plate 9 and overflow plate 8.Each overflow plate 8 all connects interlock axostylus axostyle 7, directly links to each other with motor 3 by interlock axostylus axostyle 7, and motor 3 is located at tower body 11 outsides.During motor 3 rotations, overflow plate 8 can rotate freely on column plate 5.
During the utility model work, what water inlet inlet 2 entered is the high-concentration ammonia nitrogenous wastewater that has added after organic compound denitrfying agent is also regulated through the pH value, penetrate through high pressure spray nozzle 12 from cat head, forming waterfall drops on the uppermost the first layer column plate 5, after reaching a certain height, water level overflows to down on one deck column plate 5, at the bottom of tower from overflow plate 8.Through behind repeatedly gas-liquid mass transfer and the aerated reaction, last treating water is discharged from water outlet 10.Air is transported in the boring aeration pipe 14 on every layer of column plate 5 by vent-pipe 1 road by gas blower, and the multilayer perforated pipe aerating regulation has strengthened removing treatment effect.In said process, ammonia nitrogen waste water carries out sufficient chemical reaction and aeration from column plate 5 surfaces, ammonium salt in the waste water is converted into free ammonia, countercurrent flow by gas-liquid, air constantly contacts and abundant gas-liquid mass transfer on column plate 5 surfaces with waste water, ammonia nitrogen in the waste water constantly is discharged in the gas, then from central gas 18 dischargings.Starter motor 3 during discharge of wastewater, and the universal driving shaft rod twisting causes overflow plate 8 to stagger, waste water walk around overflow plate 8 through circular waste water tunnel 17 from cat head at the bottom of flowing to tower.So repeatedly, through gas-liquid mass transfer repeatedly, the ammonia nitrogen in the waste water constantly is discharged in the gas, realizes removing fully of ammonia nitrogen in the waste water, and the water outlet 10 of the treating water of the column plate 5 by all layers at the bottom of the tower flows out outside the towers at last.
