Abstract
The utility model provides a treatment device for removing heavy metals in sewage. The treatment device comprises a tank body, wherein the bottom of the tank body is connected with a water inlet pipe; the upper end of the tank body is connected with a water outlet pipe; the inside of the tank body is sequentially provided with a primary sandstone filtering layer, a microbiological adsorption layer, filter cloth and a granular active carbon adsorption layer from bottom to top; the microbiological adsorption layer is provided with a sphere with microorganisms attached on the surface. The treatment device has the following beneficial effects that defects such as high cost, complex operation, difficulty in treating low-concentration wastewater and the like existing in the traditional metal ion removal method are overcome; due to the adoption of a microbiological treatment way and a multistage filtration and adsorption way, the treated water reaches to the recycling standard; meanwhile, potential heavy metal resources are recovered.
Description
Technical field
The utility model relates to a kind for the treatment of unit of removing heavy metal in sewage.
Background technology
Along with increasing rapidly of socioeconomic fast development and urban population, urban wastewater discharge increases day by day.Municipal effluent becomes the important sources of environmental pollution.In municipal effluent, contain a large amount of COD, NH
3the pollutant component such as-N, heavy metal.Heavy metal containing sewage can produce a large amount of harm to HUMAN HEALTH and physical environment.Heavy metal contamination has become one of problem the most serious in current environmental pollution.The method that tradition is removed metal ion has: chemical precipitation method, chemistry redox method, active carbon adsorption, ion exchange method, solvent extration, Physical, membrane separation process etc.These methods are effectively under certain condition, but have that cost is high, complicated operation, are difficult to low concentration wastewater the shortcoming such as to process.
Biosorption process is a kind of newer wastewater processing technology, is specially adapted to process large volume low concentration heavy metal water, has that less investment, running cost are low, high adsorption rate, highly selective, does not produce the advantages such as secondary pollution.Now find the potential biological adsorption material with very high metal adsorption ability of part, as seaweeds, bacterium class, Mycophyta, the discarded biological mushroom of yeast class and fermentation industry foodstuffs industry.S. cervisiae is widely used in food and drink industry, and it is a kind of solid waste, is also the biological adsorption agent with practical potentiality simultaneously, can be used as the ideal material of research the Heavy Metals Bio-adsorption mechanism.
Summary of the invention
In order to realize the advanced treatment of sewage and overcome tradition the deficiency of removing metal ion method, the present invention aims to provide a kind of method and apparatus of processing large volume low concentration heavy metal water, can effectively reduce heavy metal concentration, improve effluent quality, make to process water and can reach reuse standard; Potential heavy metal resources is reclaimed simultaneously.
Specific embodiments of the present utility model is: a kind for the treatment of unit of removing heavy metal in sewage; it is characterized in that; comprise a tank body; described tank base is connected with water inlet pipe; tank body upper end is connected with rising pipe; in described tank body, be provided with successively from the bottom to top sandstone first filter layer, microorganism adsorption layer, filter cloth and granulated active carbon adsorption layer, described microorganism adsorption layer is provided with surface attachment the spheroid of microorganism.
Further, described ball material is polyvinyl chloride or polycarbonate.
Further, described filter cloth thickness is 5～10cm.
Compared with prior art, the utlity model has following beneficial effect: the utility model has overcome that traditional removal metal ion method exists that cost is high, complicated operation, be difficult to low concentration wastewater the shortcoming such as to process, realize microbiological treatment mode by spheroid carrier, the mode of compatible cascade filtration and absorption, make to process water and can reach reuse standard, potential heavy metal resources is reclaimed simultaneously.
The utlity model has following advantage:
One) compact construction, floor space is little;
Two) biological adsorption material is industrial waste thalline, less investment, and cost is low;
Three) adopt reflux type water outlet, make the bead of attached microbial be suspended state, enlarge active surface.
Four) adsorb saturated sorbing material after desorption and regeneration, can continue to use, the heavy metal ion in stripping liquid can be recycled after treatment.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1; as shown in drawings; the present invention is the treatment unit that a kind of flow lifting type is removed heavy metal in sewage; mainly comprise a tank body; described tank base is connected with water inlet pipe; tank body upper end is connected with rising pipe, is provided with successively from the bottom to top sandstone first filter layer 1, microorganism adsorption layer 2, filter cloth 3 and granulated active carbon adsorption layer 4 in described tank body, and described microorganism adsorption layer is provided with surface attachment the spheroid of microorganism.
Through grid, the first sanitary sewage after heavy and Air Exposure, enter treatment unit by water-in from bottom, first filter through the first filter layer 1 of filling quartz sand, except suspended particulate and active sludge etc. in anhydrating.Enter again microorganism adsorption layer 2, by the biological adsorption material adhering on bead, heavy metal ion is carried out to adsorption treatment, remove the toxic heavy metal (Pb, Hg, Cu, Zn, Cd, Co etc.) in multiple sewage.The biological adsorption material that has adsorbed heavy metal is held back by filter cloth 3; further hold back other particulate matter in sewage; sewage after filter cloth 3 is held back enters granulated active carbon adsorption layer 4 again; for adsorbing, sewage is difficult to for microorganism or general oxidation style institute oxygenolysis the granulated active carbon of this layer, as phenol, benzene, oil and products thereof, sterilant, washing composition, synthetic dyestuff, aminated compounds and many artificial synthetic organic materials.
Adopt cascade filtration and absorption, utilize the feature that microorganism adsorption ability is strong, the Ideal adsorption material using microorganism as heavy metal ion; Utilize the crown_interception of quartz sand and filter cloth, guarantee that absorption reaction carries out smoothly; Utilize the further adsorption of granulated active carbon to difficult degradation pollutent, make sewage reach advanced treatment effect.Adopt industrial waste thalline S. cervisiae as biological adsorption agent, realize utilization of waste material, reduce costs.
The utility model, taking plastic pellet as carrier, adheres to a large amount of microorganisms on plastic pellet, is filled in adsorption layer.Bead is spherical or polyhedron shape, to obtain good hydraulics; Material selection polyvinyl chloride (PVC) or polycarbonate (PC), make the bead can be in suspended state in upward flow reactor.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
