Abstract
The utility model discloses heavy metal sewage treatment equipment. The equipment comprises an equipment shell 1, wherein a water inlet 2 and a water outlet 3 are formed in the two ends of the equipment shell, an anaerobic tank 5, a primary aerobic tank 6, a secondary aerobic tank 7, a heavy metal sewage purification tank 8 and a disinfection pool 9 are sequentially arranged in the equipment shell, and watermelon peel slag 13 is filled in the heavy metal sewage purification tank 8. According to the heavy metal sewage treatment equipment, heavy metals, such as zinc, chromium, cadmium, lead and the like, in wastewater can be adsorbed efficiently, and the disadvantages in the prior art that when heavy metal wastewater is subjected to treatment under low concentration, the removal effect is relatively poor, secondary pollution is easily caused, the application is limited due to too high operating and raw material cost, and the like can be overcome.
Description
Technical field
The utility model relates to a kind of sewage disposal device, relates in particular to a kind of heavy metal sewage treatment equipment.
Background technology
Contain the heavy metal ion such as a large amount of zinc, chromium, cadmium, lead are arranged in trade effluent, after these heavy metal ion enter coenocorrelation, water body and human body are had extremely ill effect.General chemical precipitation method, ion exchange method, membrane separation process, active carbon adsorption, ferrite process and the biosorption process etc. of adopting while processing this heavy metal wastewater thereby at present.As: the chemical precipitation method Treatment of Copper waste water that adopts ferrous sulfate and sodium sulphite to combine, result shows that it has good effect, Cu to copper waste water
2+Clearance reaches 97.8%.Adopt 201*7OH
-Type strongly basic anionic resin and 732Na type strong acidic ion resin are to copper waste water Treatment of Copper waste water, and result shows that they make copper ion concentration in waste water solution reach national waste water first discharge standard.Adopt copper, chromium ion in ferrite process processing waste water, result shows that it has good effect to copper, chrome waste water, but when these methods are processed heavy metal wastewater thereby under low consistency conditions, have removal effect poor, easily produce the shortcoming of secondary pollution, process cost and material cost are too high in addition, and its application is restricted.
Biological adsorption (biosorption) method has caused people's research interest because having efficient, cheap potential advantages.At present this area research person is mainly with bacterium, and fungi, algae be as research object, and obtains certain achievement.
Summary of the invention
While in order to overcome prior art, processing heavy metal wastewater thereby under low consistency conditions, have removal effect poor, easily produce secondary pollution, process cost and material cost are too high, and its application is restricted; To the thorough not enough problem of probing into of the adsorption mechanism of biological adsorption agent, the utility model adopts following technical scheme:
A kind of heavy metal sewage treatment equipment, comprise apparatus casing, and there are water-in and water outlet in described apparatus casing two ends, and the apparatus casing profile is Horizontal cylinder shape, and the left and right end is oblate structure.
Arrange successively anaerobic pond, one-level Aerobic Pond, secondary Aerobic Pond in apparatus casing, heavy metal-polluted water purifying tank, sterilization pool, separate successively by the glass reinforced plastic dividing plate, has a plurality of square flow-guiding mouths above or below dividing plate.Below one-level Aerobic Pond, secondary Aerobic Pond Aerobic Pond, a plurality of micro porous aeration heads are set, with 1: the aeration rate of 15-20 is to oxygen supply in pond.
For playing good deodorization, at anaerobic pond, one-level Aerobic Pond, secondary Aerobic Pond, in heavy metal-polluted water purifying tank, sterilization pool, the top of sewage, arrange foul smell Filtration Adsorption bed.The bed bracketing is glass-fiber reinforced plastic grille, ball shape active carbon Ball-type packing on glass-fiber reinforced plastic grille.The obnoxious flavour that produces is evenly by the absorption filter bed, by charcoal absorption.
Described Ball-type packing is the netted spherical form with ectonexine.
For reaching the purpose of heavy metal in absorption sewage, throw in the Watermelon rind slag at heavy metal-polluted water purifying tank, the connecting partition top flow-guiding mouth of heavy metal-polluted water purifying tank and sterilization pool arranges filter screen, stops the Watermelon rind slag to enter sterilization pool.
Select common in life, freely be that obtainable Watermelon rind is as raw material.With Watermelon rind → sampling → blanching softening → cross leaching filter residue → dipping by lye → rinsing → drying → pulverize → pulverize and sieve (order number: 100,80,60,40,20) → Watermelon rind dregs diet fibre.
The characteristic of gac has determined that it belongs to physical adsorption, and Watermelon rind slag main component is Mierocrystalline cellulose, and Mierocrystalline cellulose itself has very strong heavy metal chelating ability, therefore comparatively speaking, has stronger heavy metal chelating ability.
of the present utility model producing effect is: Adsorption of Heavy Metals starting material used are common life waste product, easily obtain, under while the same terms, the Watermelon rind slag is to zinc, chromium, cadmium, the plumbous adsorptive power of 4 heavy metal species that waits all is better than gac, as seen use the Watermelon rind slag during as the heavy metal ion in sorbent material absorption waste water, when having overcome prior art having processed heavy metal wastewater thereby under low consistency conditions, has removal effect poor, easily produce secondary pollution, and because of process cost and material cost too high, make the shortcomings such as its application is restricted, and the probing into of adsorption mechanism to biological adsorption agent has certain understanding.
