Abstract
The utility model provides a sewage treatment device. The device is characterized in that the device comprises a shell, wherein a heavy metal sewage purifying area and a disinfecting area are distributed in the shell; a dialysis membrane is arranged between the heavy metal sewage purifying area and the disinfecting area; a cover hole is formed in the shell, corresponding to the heavy metal sewage purifying area; and a vent is formed in the shell, corresponding to the disinfecting area. The device is beneficial to application and popularization of bioremediation technology and effectively utilizes the characteristic that leaf residues of asparagus lettuce adsorb heavy metal ions so as to treat the water bodies polluted by heavy metals.
Description
Technical field
The utility model relates to a kind of green technology that the sewage that contains heavy metal is processed, and relates in particular to a kind of waste disposal plant.
Background technology
In trade effluent, contain the heavy metal ion such as a large amount of zinc, chromium, cadmium, lead are arranged, after these heavy metal ion enter coenocorrelation, water body and human body are had to 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 ferrite process to process copper, the chromium ion in 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
The purpose of this utility model is to provide can utilize the asparagus lettuce leaf slag water body to be purified to a kind of waste disposal plant of absorption to copper, chromium, cadmium, plumbous 4 kinds of different heavy metals in trade effluent,
The utility model is achieved in that a kind of waste disposal plant, comprise housing, there are water-in and water outlet in described housing two ends, the apparatus casing profile is Horizontal cylinder shape, in housing, be furnished with heavy metal containing sewage purifying area and sterilizating area, between heavy metal containing sewage purifying area and sterilizating area, be provided with dialysis membrane, heavy metal containing sewage purifying area top is positioned on housing and is provided with lid mouthful, and described dialysis membrane is fixed on described inner walls with latex.
On described housing, ventage is set, described ventage is positioned at the top of described sterilizating area.
The aperture of described sewage dialysis membrane is 150-200nm.
Select common in life, freely be that obtainable asparagus lettuce leaf is as raw material.By asparagus lettuce leaf → sampling → blanching softening → cross leaching filter residue → dipping by lye → rinsing → drying → pulverize → pulverize and sieve (order number: 100,80,60,40,20) → asparagus lettuce leaf dregs diet fibre.
The characteristic of gac has determined that it belongs to physical adsorption, and asparagus lettuce leaf slag main component is Mierocrystalline cellulose, and Mierocrystalline cellulose itself has very strong heavy metal chelating ability, and asparagus lettuce leaf slag especially used, through alkaline purification, 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 asparagus lettuce leaf slag is to zinc, chromium, cadmium, the plumbous adsorptive power of 4 heavy metal species that waits all is better than gac, using the asparagus lettuce leaf slag during as the heavy metal ion in sorbent material absorption waste water as seen, 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.
The accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
The accompanying drawing mark: 1 is housing, 2 water-ins, and 3 is water outlet, and 4 is heavy metal sewage purification district, and 5 is sterilizating area, and 6 is ventage, and 7 are lid mouthful, and 8 is the asparagus lettuce leaf slag, and 9 is dialysis membrane.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described.
As shown in Figure 1, a kind of waste disposal plant, comprise housing 1, and there are water-in 2 and water outlet 3 in described housing two ends 1, and housing 1 profile is Horizontal cylinder shape.In housing 1, be distributed with heavy metal containing sewage purifying area 4 and sterilizating area 5; Between heavy metal containing sewage purifying area 4 and sterilizating area 5, be provided with dialysis membrane 9, heavy metal containing sewage purifying area 4 tops are positioned on housing 1 and are provided with lid mouth 7, can add asparagus lettuce leaf slag 8 by lid mouth 7, described dialysis membrane 9 use latexes are fixed on described housing 1 inwall, and ventage 6 is set on housing 1.
Described ventage is positioned at the top of described sterilizating area 5.
The aperture of described dialysis membrane 9 is 150-200nm.
Working process is summarized as follows: at first, heavy metal containing sewage is pumped in the space of heavy metal purifying area 4, make it be full of heavy metal purifying area 4, then by lid mouth 7, asparagus lettuce leaf slag 8 is added in heavy metal purifying area 4, and along with pump working, processed water constantly enters the space of sterilizating area 5, air in space is discharged by air outlet 6, and the water in sterilizating area 5 can be discharged by water outlet 3.By above treating processes, heavy metal containing sewage is processed into domestic water.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the person skilled in the art understand content of the present utility model and implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model spirit change or modify, and all should be encompassed in protection domain of the present utility model.
