Description
Technical field
The utility model relates to water treatment field, particularly a kind of running water by disposal of depth system.
Background technology
Along with Economic development, the environmental pollution of waterhead area is more and more serious, a large amount of dissolved organic matters, heavy metal and microorganism have entered water body, traditional water technology has been difficult to satisfy new purification of water quality requirement, and the tap water of handling is depended alone to boil and can not be satisfied the demand that citizen drink safely.For strengthening water quality safety, 2007, country issued new " drinking water sanitary standard ", and water quality standard is brought up to 106 indexs to the requirement of drinking-water quality from original 35 indexs.The new standard emphasis has been strengthened the control requirement to microorganism, heavy metal and organic pollutant, and water quality standard basic and international organization and developed country integrates with.Implementing in full of standard brought new challenge to traditional water treatment technique.
The water treatment technology has been passed through the development in more than 100 year, and domestic treatment process mainly contains at present: 1) traditional coagulation, precipitation, filtration, chlorination four step rule technique; 2) the deep oxidation technique take ozone, gac as core, 3) combination process take ultra-filtration membrane as core etc.Wherein, four step rule technique is mainly removing suspended substance, turbidity, colourity and pathogenic bacteria in the former water as main, and it is extremely limited that dissolved organic matter and heavy metal are removed ability; Deep oxidation technique take ozone, gac as core although solved the harm problem of poisonous micro-content organism and chlorinated disinfection by-products, is removed the micro heavy in the middle of the water body and is not also played a role; Combination process take ultra-filtration membrane as core can effectively reduce the chloro precursor, and delivery turbidity remains at extremely low-level, can reach 100% to hydrobiont clearances such as bacterium, two worms (Cryptosporidium and giardia lamblia stiles), algae, but equally the removal of heavy metal almost not had help.
Present stage, the Organic pollutants of the nearly all waterhead area of China are all constantly increasing the weight of, and heavy metal contamination is frequent occurrence also.Though above technique can be removed a small amount of organism and microorganism, and is not obvious to the heavy metal removal effect in the water body, is difficult to the water quality standard that reaches new.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of running water by disposal of depth system that can effectively remove the heavy metal in the tap water.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of running water by disposal of depth system, comprise the coagulation basin, settling tank, filtration unit, the sterilizing unit that connect by pipeline successively, it is characterized in that: also be provided with a heavy metal adsorption fluidized-bed between described filtration unit and sterilizing unit, being filled with manganese in the described heavy metal adsorption fluidized-bed is inorganic composite materials.
Further, described heavy metal adsorption fluidized-bed bottom is provided with a water-in, and the top is provided with a water outlet, and the upper and lower part respectively is provided with a porous liquid grid distributor in the heavy metal adsorption fluidized-bed, and described manganese is that inorganic composite materials is located between the porous liquid grid distributor.
Further, described filtration unit is plate-and-frame filter press, sandfiltration pot, membrane sepn filtration unit etc.
Further, described manganese is that inorganic composite materials comprises: Manganse Dioxide (α-MnO
2, β-MnO
2, γ-MnO
2, δ-MnO
2, λ-MnO
2), manganic oxide (Mn
2O
3), trimanganese tetroxide (Mn
3O
4) and manganese oxide octahedron molecular screen (OMS-2) etc.
Adopt technique scheme, the advantage that running water by disposal of depth described in the utility model system has is:
1) the Adsorption of Heavy Metals ability is strong, and loading capacity is large;
2) simple to operate, easy to use, operation expense is low;
3) water yield, the component of tap water there is stronger adaptive faculty;
4) it is extremely low-level the water outlet heavy metal to be remained at;
5) regeneration is convenient, and use during regeneration sour reusable.
Description of drawings
Fig. 1 be the utility model the running water by disposal of depth system schematic;
Fig. 2 is heavy metal adsorption fluidized-bed basic block diagram of the present invention;
Wherein: 1. coagulation basin, 2. settling tank, 3. filtration unit, 4. heavy metal adsorption fluidized-bed, 41. water-ins, 42. porous liquid grid distributors, 43. manganese are inorganic composite materials, 44. water outlets, 5. sterilizing unit.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, a kind of running water by disposal of depth system, comprise the coagulation basin 1, settling tank 2, filtration unit 3, heavy metal adsorption fluidized-bed 4, the sterilizing unit 5 that connect successively by pipeline, being filled with manganese in the heavy metal adsorption fluidized-bed 4 is inorganic composite materials 43, concrete heavy metal adsorption fluidized-bed 4 bottoms are provided with a water-in 41, the top is provided with a water outlet 44, heavy metal adsorption fluidized-bed 4 interior upper and lower parts respectively are provided with a porous liquid grid distributor 42, and manganese is that inorganic composite materials 43 is located at 42 of porous liquid grid distributors.
Further, described filtration unit 3 is plate-and-frame filter press, sandfiltration pot, membrane sepn filtration unit etc.
Further, described manganese is that inorganic composite materials 43 comprises: Manganse Dioxide (α-MnO
2, β-MnO
2, γ-MnO
2, δ-MnO
2, λ-MnO
2), manganic oxide (Mn
2O
3), trimanganese tetroxide (Mn
3O
4) and manganese oxide octahedron molecular screen (OMS-2) etc.
My improvement made on the basis of tap water conventional processes of running water by disposal of depth described in the utility model system, namely adopting Twin-Screw Extrusion Technology to make manganese is that inorganic composite materials is shaped, and be that inorganic composite materials is filled in the fluidized-bed as sorbing material with the manganese that is shaped, be installed on the water treatment end, a small amount of heavy metal in the absorption tap water under fluidized state, it is extremely low-level that the water outlet heavy metal is remained at.Thereby guarantee that tap water quality reaches new " sanitary standard for drinking water ".Manganese is that inorganic composite materials belongs to Mn oxide, and is water insoluble, the phenomenon that therefore exceeds standard without water body manganese.Because manganese is that the inorganic adsorbing material loading capacity is very large, the time that reaches capacity is long, can adapt to the fluctuation of water quality simultaneously.
Manganese be the inorganic composite materials Adsorption of Heavy Metals to adopt concentration after saturated be that the nitric acid of 10-25% carries out wash-out, Adsorption of Heavy Metal Ions again after the wash-out regeneration; Elutriant adopts oxalic acid treatment, and heavy metal and oxalic acid form precipitation and removes, and elutriant is purified and can be recycled.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but the those skilled in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
