Technical field
The present invention relates to a kind for the treatment of apparatus and processing method thereof 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. CityCity's sewage becomes the important sources of environmental pollution. In municipal sewage, contain the pollutant components such as a large amount of COD, NH3-N, heavy metal. HeavyMetal sewage can produce a large amount of harm to health and natural environment. Heavy metal pollution has become in current environmental pollutionOne of the most serious problem. The method that tradition is removed metal ion has: chemical precipitation method, chemistry redox method, charcoal absorptionMethod, ion-exchange, solvent extraction, Physical, membrane separation process etc. These methods are effectively under certain condition, but deposit, complicated operation high at cost, be 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 uselessWater, has that small investment, running cost are low, high adsorption rate, high selectivity, does not produce the advantages such as secondary pollution. Discovery portion nowDivide the potential biological adsorption material with very high metal adsorption ability, as seaweeds, bacterium class, Mycophyta, yeast classDiscarded biological mushroom with fermentation industry food industry. S. cervisiae is widely used in food and beverage industry, and it is a kind of solidWaste material 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.

In order to realize the advanced treating of sewage and overcome tradition the deficiency of removing metal ion method, the present invention aims to provideProcess a method and apparatus for large volume low concentration heavy metal water, can effectively reduce heavy metal concentration, improve water outlet waterMatter, makes to process water and can reach reuse standard; Potential heavy metal resources is reclaimed simultaneously.
Specific embodiment of the invention scheme is: a kind for the treatment of apparatus of removing heavy metal in sewage, it is characterized in that, and compriseOne tank body, described tank base is connected with water inlet pipe, and tank body upper end is connected with outlet pipe, in described tank body, establishes successively from the bottom to topHave sandstone first filter layer, microorganism adsorption layer, filter cloth and granular activated carbon adsorption layer, described microorganism adsorption layer is provided with surface attachmentThere is the spheroid of microorganism.
Further, described ball material is polyvinyl chloride or Merlon.
Further, described filter cloth thickness is 5～10cm.
The second embodiment of the present invention is: a kind of processing method of removing heavy metal in sewage, comprises as claim 1Described a kind for the treatment of apparatus of removing heavy metal in sewage, is characterized in that comprising the following steps:
(1) select saccharomycete to carry out biological device absorption bacterium, saccharomycete is located in advance with alkalescence or weak alkaline aqueous solutionReason, saccharomycete after pretreatment is extremely neutral with deionized water washing through ebuillition of heated, be dried, grind;
(2) saccharomycete step 1 being formed is attached on plastic beads, and the plastic beads that is attached with microorganism is thrown inIn device biological adsorption layer;
(3) unlatching water inlet pipe makes the treating apparatus work of heavy metal.
Compared with prior art, the present invention has following beneficial effect: the present invention has overcome traditional removal metal ion sideMethod exists that cost is high, complicated operation, be difficult to low concentration wastewater the shortcoming such as to process, and realizes microorganism place by spheroid carrierReason mode, the mode of compatible multistage filtering and absorption, makes to process water and can reach reuse standard, simultaneously to potential heavy metal moneyReclaim in source.
The present invention has the following advantages:
One) compact conformation, floor space is little;
Two) biological adsorption material is industrial waste thalline, small 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 throughAfter processing, recycle.

Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in Figure 1, as shown in drawings, the present invention is the treating apparatus that a kind of up-flow is removed heavy metal in sewage, mainComprise a tank body, described tank base is connected with water inlet pipe, and tank body upper end is connected with outlet pipe, in described tank body from the bottom to topBe provided with successively sandstone first filter layer 1, microorganism adsorption layer 2, filter cloth 3 and granular activated carbon adsorption layer 4, described microorganism adsorption layer is establishedThere is surface attachment to have the spheroid of microorganism.
Through grid, the first sanitary sewage after heavy and Air Exposure, enter treating apparatus by water inlet from bottom, first through filling outThe first filter layer 1 that fills quartz sand filters, except suspended particulate substance and activated sludge etc. in anhydrating. Enter again microorganism adsorption layer 2, logicalCross the biological adsorption material adhering on bead heavy metal ion is carried out to adsorption treatment, remove the toxic heavy metal in multiple sewage(Pb, Hg, Cu, Zn, Cd, Co etc.). The biological adsorption material that has adsorbed heavy metal is held back by filter cloth 3, further holds back in sewageOther particles, the sewage after filter cloth 3 is held back enters granular activated carbon adsorption layer 4 again, the granular activated carbon of this layer is used forAbsorption is difficult in sewage for microorganism or general oxidizing process institute oxidation Decomposition, as phenol, benzene, oil and products thereof, pesticide, washWash agent, synthetic dyestuffs, aminated compounds and many artificial synthetic organic materials.
Adopt multistage filtering and absorption, utilize the feature that microorganism adsorption ability is strong, using microorganism as heavy metal ionIdeal adsorption material; Utilize the crown_interception of quartz sand and filter cloth, guarantee that adsorption reaction carries out smoothly; Utilize granular activated carbonTo the further suction-operated of difficult degradation pollutant, make sewage reach advanced treating effect.
