Adopt system of the present invention, can effectively remove suspended substance, particulate matter and radiocobalt-60 metal ions in the cobalt-source well water, make cobalt-source well water water quality can meet national relevant specification requirement for a long time, solve source well water evaporative fill water-filling and prevent that cobalt source well from carrying out emergency processing in operational process just in case when cobalt source part leakage accident may take place.Native system, equipment is simple, and is easy to maintenance, and processing ease is that a cover suitability is strong, stability, the good system for treating cobalt-source well water circulation of security tool.
Description of drawings
Fig. 1 is the system architecture synoptic diagram.
Embodiment
Referring to Fig. 1, system of the present invention comprises water inlet pipe 1, line strainer 2, water pump 3, more medium filter 4, accurate filter 5, is filled with the ion-exchanger 6 of ion exchange resin, security personnel's strainer 7 and water tank 8;
One end of said water inlet pipe 1 stretches into well 9 bottoms, cobalt source, the other end is connected by the inlet of pipeline with line strainer 2, the outlet of line strainer 2 is connected by the inlet of pipeline with water pump 3, the outlet of water pump 3 is connected by the inlet of pipeline with more medium filter 4, the outlet of more medium filter 4 is connected by the inlet of pipeline with accurate filter 5, the outlet of accurate filter 5 is connected with the inlet that is filled with ion exchange resin ion-exchanger 6 by pipeline, the outlet that is filled with ion exchange resin ion-exchanger 6 is connected by the inlet of pipeline with security personnel's strainer 7, and the outlet of security personnel's strainer is connected with cobalt source well 9 with water tank 8 by pipeline respectively;
Said line strainer is selected 80～120 order line strainers for use, does coarse filtration, can prevent that large granular impurity from entering water pump, can adopt commercially available standard prod, is the product of DN40 as bore;
In the said more medium filter, be filled with filtrates such as quartz sand and fruit stone type gac, filtering accuracy is 100 μ m.Under the state that "dead" cobalt-60 leaks, can carry out regular back flushing, remove to filter and hold back material, keep the efficient and the filtering accuracy of strainer, prevent to stop up and lost efficacy.In case polluted by radiocobalt-60, need to change filtrate or use after treatment;
2～4 polypropylene 10 μ m filter cores of the inner installation of said accurate filter, it prevents that mainly introduced contaminants from entering in the system, also guarantees preposition filtering accuracy requirement simultaneously, guarantees filter quality;
The said ion exchange resin that is filled with in the ion exchange resin ion-exchanger 6 is the mixture of anionite-exchange resin and Zeo-karb, preferred poly-third ethene Zeo-karb and the anionite-exchange resin, the volume ratio of Zeo-karb and anionite-exchange resin is 1: 1.5～2.5, and the model that can adopt Rhom and Hass to produce is the nuclear level product of IRN160;
Because native system needs process source well water, keep the water quality of source well water, have radiocobalt ion processing ability simultaneously, require ion exchange resin to have radiation resistance, select for use nuclear grade ion-exchange resins do native system exchanger proper.Cobalt source recirculated water, directly contact with the cobalt source, unavoidably being subjected to cobalt-60 ionic pollutes, in case ion exchange resin comes out the radiocobalt ion-exchange in the recirculated water, if saturated back manipulation of regeneration, the radiocobalt ionic transformation period is longer, and there is the possibility of radiation pollution in born again waste water, influence surrounding environment, can not directly discharge, storing these waste water has certain degree of difficulty again, and part leakage in radiocobalt source is a kind of Special Circumstances, what handle is again recirculated water, need the ion-exchange concentration of exchange lower, the ion-exchange load is less, and the saturated cycle is long, treat to load again when saturated new ion exchange resin, when "dead" cobalt leaks, change ion exchange resin, can be by general waste treatment, if carried out radiocobalt ion-exchange, must collect the back and hand over relevant department to handle as radwaste.
Dress folded membrane polypropylene filter core in said security personnel's strainer, filtering accuracy is 0.45 μ m, its effect can prevent that exhausted resin from leaking, play the usefulness of resin catcher, can reach the effectiveness of fine filter again, the recirculated water cleaning that guarantees to enter cobalt source well is dustless, satisfies its requirement;
According to the preferred scheme of the present invention, the outlet of accurate filter 5 is connected with the outlet that is filled with ion exchange resin ion-exchanger 6 by bypass line 13, because need to consider the cost of ion exchange resin, little as recirculated water intermediate ion concentration, in the scope of control, can pass through bypass line 13, without crossing ion-exchanger, only make filtration treatment; If ionic concn raises in the time of will exceeding standard, close by-pass valve, cut off by-pass line, recirculated water enters ion-exchanger, handles, and reduces specific conductivity, and the life cycle that can prolong ion exchange resin so greatly reduces running cost.
System of the present invention also comprises pure water preparation device 10, for routine by mechanical filter.Charcoal filter, first-stage reverse osmosis machine are formed, and are connected with water tank 8 mutually with the source well by pipeline, with supplementary source well water;
According to the preferred scheme of the present invention, system also comprises the urgent water pipe 12 that replenishes that is connected with the municipal tap water pipeline, its effect is in the cobalt source well situation of undergoing mutation, water leaks in a large number in the well of source, when having had a strong impact on cobalt unit and normally having moved, need to use a large amount of make up water, guarantee that the cobalt source is under the safety level.
According to the present invention, native system also comprises cooling system 11 cooling systems that are arranged between water pump and the more medium filter 4, when cobalt unit intensity during greater than 1,000,000 Curie, cobalt-source well water is cooled off.
