Background technology
In dyeing waste water and the During Industrial Wastewater Treatment Process based on dyeing waste water, technique that sewage treatment process generally adopts " pre-treatment+anaerobism/acidication+aerobic+materialization dosing ", wherein anaerobism/acidication process section is made up of anaerobism or reactor for hydrolysis and acidification, settling tank, sludge recirculation system.In anaerobism or reactor for hydrolysis and acidification, active sludge contacts with the Homogeneous phase mixing of stain disease, basic by power-equipment realizations such as submersible agitators, operation process medium power equipment needs running continuously, in reactor, sludge concentration is generally at 3-5g/l, accessible waste water is few, need in operational process to consume a large amount of kinetic energy, mud handling capacity is few, and treatment effect is low.
Based on this, make subject application.
Utility model content
In order to overcome in existing sewage treatment process existing above-mentioned defect, the utility model provides a kind of rapidly and efficiently can carry out sewage sludge discharge, flow lifting type anaerobic reactor that processing efficiency is high.
For achieving the above object, the technical scheme taked of the utility model is as follows:
A kind of flow lifting type anaerobic reactor, comprise water inlet pipe, water distribution area, reaction zone, exhalant region, rising pipe and shore pipe, described water distribution area is up big and down small pyramidal structure, and its lower end is connected with water inlet pipe, and upper end is then communicated with reaction zone; Be provided with dividing plate between reaction zone and water distribution area, described dividing plate arranged laminates hydrosphere line, each water distribution astragal is distributed with multiple water distributing pore, reaction zone realizes being communicated with by dividing plate with water distribution area; Described reaction zone becomes sludge blanket near the region of dividing plate; Both sides, reaction zone are provided with many shore pipes, and each shore pipe is evenly arranged; Upper end, reaction zone is exhalant region, and top, exhalant region sets out tank, and this effluent trough place is connected with rising pipe, and described effluent trough is made up of outer ring and inner ring, and outer ring is higher than inner ring, and outer ring is provided with dentalation in its cross-sectional direction.
Further, as preferably:
Be provided with stirrer above described sludge blanket, for sludge blanket is stirred, to change the degree of compactness of sludge blanket, prevent from blocking dividing plate.
Be connected with below described water distribution area and take out pump, for the mud sinking to water distribution area is extracted to upper end, reaction zone, again precipitate.
Described outer ring height is 100mm, and dentalation height is wherein 40mm.
On described dividing plate, the spacing between adjacent water distribution astragal is 50mm, and on each water distribution astragal, the spacing of adjacent water distributing pore is 50-60mm, and the aperture of each water distributing pore is 10-15mm.
The taper theta of described water distribution area is 45 °.
The utility model is applied to dyeing waste water or the trade effluent based on dyeing waste water, its principle of work and beneficial effect as follows:
1) one piece of dividing plate (circle) has been established between water distribution area and reaction zone, dividing plate is to be equipped with the water distributing pore of aperture 1cm-1.5cm, water distributing pore comparatively dense be distributed on dividing plate, point centered by the dividing plate center of circle, central point has beaten water distributing pore, every outwards 5cm establishes a water distribution astragal, and water distribution astragal establishes a water distributing pore every 5-6cm; Anaerobic activated sludge in reaction zone can be deposited on dividing plate, forms the anaerobic sludge layer up to several meters, i.e. anaerobic reaction district.Stain disease sends into water distribution area through water inlet pipe, and enter reaction zone by water distributing pore, sewage passes anaerobic sludge layer with rising manner, when stain disease is through after sludge blanket, even if mud is by disturbance, by action of gravity, mud can sink on sludge blanket, organic pollutant in stain disease is retained by the anaerobion in sludge blanket, carries out assimilating, decomposition reaction, and in the settling region at top, reaction zone, sewage is then flowed out through rising pipe by the effluent trough of exhalant region.
2) in the utility model, when sludge blanket is deposited on dividing plate, part anaerobic sludge can fall into water distribution area by water distributing pore, and the anaerobic sludge falling into water distribution area is by water distribution area shore pipe and take out pump and again send into settling region on reaction zone; The setting of water distribution area spoil disposal and pump, avoids deposition in water distribution area to cause blocking.Meanwhile, mud goes back to the settling region on water distribution area, by redistribution on the sludge blanket of reaction zone.
3) sludge blanket in anaerobic reaction district, if piled up closely knit, the stain disease that water distributing pore can be caused to enter rose through sludge blanket difficulty.Mud layer needs to re-start accumulation sometimes, in the present embodiment, be provided with agitator in reaction zone, when mainly needing to reduce sludge blanket packing density, turn on agitator stirs loose sludge blanket, and after stopping agitator, mud again can be piled into sludge blanket in the process of gravity settling.After this process, sludge blanket degree of compactness can reduce.
4) 4 shore pipes are respectively established on both sides, reaction zone, and distribute setting from the bottom up; In sludge blanket mud is too much, carry out spoil disposal process.
Flow lifting type anaerobic reactor of the present utility model, after the water distributing pore of stain disease by water distribution area, upwards flow through in the process of sludge blanket, stain disease can fully contact with the anaerobion of sludge blanket.In this process, do not need the power-equipments such as agitator to realize fully mixing of stain disease and anaerobic sludge.The sludge concentration being deposited in the anaerobic sludge layer on dividing plate can reach about 20g/l, far above 3-5g/l of the dense mud of traditional anaerobic reactor mud.Because the concentration of sludge blanket is up to about 20g/l, the efficiency that corresponding anaerobic reaction removes the organic contamination in stain disease is much higher.Tradition anaerobic reactor is in the process for the treatment of of dyeing and printing, and COD clearance is at 10-15%, and this reactor COD clearance can reach about 30%.
A kind of flow lifting type anaerobic reactor of the utility model has merged reaction process and precipitation process, anaerobic reaction, precipitate and separate function are integrated in upflow-type reactor, the technological process that after avoiding traditional anaerobic reaction, redeposition is separated, corresponding investment also reduces, run control all comparatively easy, and wastewater treatment efficiency there is obvious lifting.
