Description
Technical field
The utility model relates to a kind ofly can handle isolating device to heavy metals such as micro-antimonies in the source water of Drinking Water.
Background technology
Antimony is the main raw material of alloy manufacturing, printing and pigment production, and the danger label of metallic antimony is 15 (harmful product are away from food).The approach that antimony enters human body comprises suction, eats, and main harm is that mucous membrane is had hormesis, can cause visceral lesion, its acute toxicity LD
507000mg/kg (rat oral).The acute effects that contact higher concentration antimony causes has chemical conjunctivitis, rhinitis, pharyngitis, laryngitis, bronchitis, pneumonia; The oral acute gastroenteritis that causes, constitutional symptom has fatigue and weak, dizziness, headache, limb muscle ache, and can cause the heart, liver, renal impairment.Chronic influence comprises headache, dizziness, easily excitement, insomnia, weak, gastrointestinal dysfunction, mucous membrane irritation symptom.Antimony pollution in the environment comprises artifact pollution (stibiated rubbish, the dust that mining causes, waste water, waste residue, the coal that gasoline and thermal power station are used etc. contains the burning of antimony fuel) and natural pollution (rich antimony ore district, some hot spring and geothermal area to contain the antimony amount higher).Natural water body will finally become the environment home to return to of most of antimony.Be subjected to the influence of factors such as rock decay, rain drop erosion and anthropogenic discharge, antimony is present in the water surrounding with all cpds form or with suspended state or with solubilised state.
At present, in China's Drinking Water heavy metal antimony be mainly derived from upstream blowdown of source water dry point from the beginning and the mineral reserve that the water source is rich in non-ferrous metal antimony with flowing through.The source of pollution difference, the main component of the antimony of formation is also different, and the antimony that the former discharges mainly is present in the water body with ionic condition, and the valence state of existence mainly is trivalent and pentavalent, and the composition of the antimony that the latter generates is mainly molecular state.According to the thermodynamic argument of antimony modality, in the oxygen enrichment water body (as surface water), antimony should mainly exist with pentavalent, vice versa, yet in fact, it is found that not only trivalent antimony can exist under some oxygen-enriched environments, and quinquevalence antimony can occur under anaerobic environment also.Tracing it to its cause, is that except that dissolved oxygen, settling, biology, suspended particle all might make a difference to the form of antimony because of the physicochemical environment more complicated in the actual water body.Just generally speaking, still mainly be quinquevalence antimony in the surface water, be present in the water with very stable neutral molecule.
The improvement present situation of antimony pollution: high density antimony is handled a small amount of application, and the improvement of lower concentration antimony pollution does not also have extremely successful case, is in the research experiment stage mostly, no large-scale application example or processing cost height.
The processing of antimony is primarily aimed at the high density stibium-containing wastewater in the existing water, and is worldwide actually rare for the processing of antimony in the Drinking Water.Simultaneously, because antimony concentration low (common＜100 μ g/L), difficult in the Drinking Water, up to the present, to the antimony pollution sophisticated treatment unit of none also of trace in the Drinking Water, the water quality after the processing also is difficult to reach drinking water standard and requires (antimony limit value≤5 μ g/L) in the world.
The utility model content
The purpose of this utility model aims to provide a kind of water treatment device, can effectively separate heavy metals such as micro-antimonies in the source water of Drinking Water, makes the water quality after the processing can reach the drinking water standard requirement.
The technical solution of the utility model is: comprise active water Buffer Pool, coagulation basin, settling tank, topping-up pump, more medium filter, accurate filter I, high-pressure pump, and nanofiltration membrane or reverse osmosis membrane equipment, and be connected in sequence by above equipment with polyamide composite film, cellulose acetate membrane, polyvinyl alcohol derivative film or urea polyamide membrane material.
Be connected with sterilant chemicals dosing plant and coagulating agent chemicals dosing plant on source water Buffer Pool, the coagulation basin respectively.
Be provided with reductive agent chemicals dosing plant and Scale inhibitors chemicals dosing plant between more medium filter and the accurate filter I successively.
Described nanofiltration membrane or reverse osmosis membrane equipment are connected with washing unit by purge control valve.
Described washing unit is to be connected in sequence by cleaning water tank, flushing water pump, accurate filter II, and is linked to each other with the import of nanofiltration membrane or reverse osmosis membrane equipment by the accurate filter II of the washing unit inlet valve by purge control valve; The outlet of nanofiltration membrane or reverse osmosis membrane equipment links to each other with the cleaning water tank by the outlet valve of purge control valve.
What described accurate filter preferably adopted is the filer element type strainer.
The entrance and exit of topping-up pump respectively is serially connected with a pressure controller.
Topping-up pump and high-pressure pump outlet are connected with check valve, prevent to manage interior aqueous reflux, impact the impeller of water pump, also can prevent the piping system air inlet.
Topping-up pump, more medium filter, accurate filter, high-pressure pump, and the connecting tube of nanofiltration membrane or reverse osmosis membrane equipment is provided with pressure and takes into account under meter.
The outlet of nanofiltration membrane or reverse osmosis membrane equipment is connected with conductivity meter.
Advantage of the present utility model is: adopt device of the present utility model to handle the Drinking Water antimony pollution, and the clearance height, treatment effect is highly stable, is not subjected to Effect of Environmental substantially.Technology maturation, result are easy to control, and the level of automation height can be completely achieved fully automatic operation, and running cost is low.
