A kind of cleaning system that the radioactive contamination water treatment is become potable water
Technical field
The invention belongs to a kind of water purification device; Be specifically related to a kind ofly when being mainly used in the open air, can apace domestic waters such as containing above underground water of above surface water of radioactive V class that exceeds standard or IV class or tap water be processed into the cleaning system of Drinking Water with the operation of nuclear pollution zone.
Background technology
Along with rapid development of high and new; The complicacy of future war and Unpredictability have become inevitable, in case accidents such as nuclear blast, nuclear leakage, biological warfare, chemical warfare, the attack of terrorism take place, not only cause casualties; The more important thing is the severe contamination that can cause to environment; Especially at the large size city of resident's population concentration, need the low-activity water treatment be become Drinking Water, be used at nuclear pollution zone preparation potable water.At present, the water purification system complex structure of prior art, expense height, and also purification is not thorough, does not often reach the standard of potable water.
Summary of the invention
The present invention proposes for the shortcoming that overcomes the prior art existence, and its objective is provides a kind of cleaning system that can apace the low-activity water treatment be become Drinking Water.
Technical scheme of the present invention is: a kind of cleaning system that the radioactive contamination water treatment is become potable water; Comprise the pump of surging, pretreating device, membrane separation device and after-treatment device; The described delivery side of pump of surging is communicated with the inlet of micro-filtration filtrator; The outlet of micro-filtration filtrator is communicated with the inlet of ultra filtration filter, and the outlet of ultra filtration filter is communicated with the inlet of high-pressure pump.Pipeline between ultra filtration filter and the high-pressure pump is provided with chemicals dosing plant; The high pressure delivery side of pump is communicated with the inlet of reverse osmosis filter group; The water outlet of reverse osmosis filter group is communicated with the inlet of combined type adsorber; The outlet of combined type adsorber is communicated with the inlet of sterilizer, and the outlet of sterilizer is communicated with the inlet of accurate filter.
Described micro-filtration filtrator is made up of Stainless Steel Shell and many 1~10 μ m filter cores.
Described reverse osmosis filter group is made up of many reverse osmosis filter SP, and every reverse osmosis filter is made up of glass steel shell and reverse osmosis membrane.
Described combined type adsorber by glass steel shell with in adorn many absorption filter cores and form, adsorbing filter core is the compound adsorbent that contains carbon and resin combination.
Described accurate filter is made up of stainless steel cylinder and 0.1~5 μ m filter core.
The present invention is rational in infrastructure, and is easy to use, and water treatment is thorough, can make the radioactive contamination water treatment become the standard of potable water.

Fig. 1 is that cleaning system of the present invention is arranged synoptic diagram.
Wherein:
1 pump 2 pretreating devices of surging
3 membrane separation devices, 4 after-treatment devices
5 micro-filtration filtrators, 6 ultra filtration filters

Embodiment
Below, a kind of become the cleaning system of potable water to be elaborated the radioactive contamination water treatment with reference to accompanying drawing and embodiment to of the present invention:
As shown in Figure 1, a kind of the radioactive contamination water treatment is become the cleaning system of potable water, comprise the pump 1 of surging, pretreating device 2, membrane separation device 3 and after-treatment device 4.Wherein pretreating device 2 comprises micro-filtration filtrator 5, ultra filtration filter 6 and chemicals dosing plant 7; Membrane separation device 3 comprises high-pressure pump 8 and reverse osmosis filter group 9; After-treatment device 4 comprises combined type adsorber 10, sterilizer 11 and accurate filter 12.
Wherein, The outlet of pump 1 of surging is communicated with the inlet of micro-filtration filtrator 5; The outlet of micro-filtration filtrator 5 is communicated with the inlet of ultra filtration filter 6, and the outlet of ultra filtration filter 6 is communicated with the inlet of high-pressure pump 8, and the pipeline between ultra filtration filter 6 and the high-pressure pump 8 is provided with chemicals dosing plant 7.The outlet of high-pressure pump 8 is communicated with the inlet of reverse osmosis filter group 9; The water outlet of reverse osmosis filter group 9 is communicated with the inlet of combined type adsorber 10; The outlet of combined type adsorber 10 is communicated with the inlet of sterilizer 11, and the outlet of sterilizer 11 is communicated with the inlet of accurate filter 12.
End in reverse osmosis filter group 9 also is provided with dense water out, and the outlet of accurate filter 12 is a pure water inlet.
Wherein, micro-filtration filtrator 5 is made up of Stainless Steel Shell and many 1~10 μ m filter cores, can remove suspended particle and impurity in the water.
Ultra filtration filter 6 is made up of many glass steel shells and ultra filtration filter membrane, mainly removes all kinds of colloids and all kinds of big molecule in the water.
Chemicals dosing plant 7 is made up of dosing pump and soup, and soup is the macromolecule antisludging agent, is mainly used in to prevent the fouling in reverse osmosis filter of indissoluble salt.Reverse osmosis filter group 9 is made up of many reverse osmosis filter SP, and every reverse osmosis filter is made up of glass steel shell and reverse osmosis membrane, can remove most of inorganic salts in the water, amino acid, BOD, COD, bacterium, virus and part salt.
Combined type adsorber 10 by glass steel shell with in adorn many absorption filter cores and form, adsorbing filter core is the compound adsorbent that contains carbon and resin combination, mainly removes the radiomaterial in the water, avoids the various harm of radioactive nuclide.
Sterilizer 11 is a ultraviolet sterilizer, can kill bacterium residual in the water.
Accurate filter 12 is made up of stainless steel cylinder and 0.1~5 μ m, further removes various residual suspended particles and impurity in the water, makes it reach the standard of potable water.
The present invention is rational in infrastructure, and is easy to use, and water treatment is thorough, can make the radioactive contamination water treatment become the standard of potable water.
