Description
Technical field
The utility model, about water treatment, particularly relates to a kind of oil well, the treatment unit of coal bed gas well output water of high fluorine content and treatment process thereof.
Background technology
Fluorine is one of requisite trace element of human life, and human body is respectively organized all fluorine-containing, maximum with the fluorine content of tooth, bone and hair.Appropriate fluorine can make bone tooth solid, reduces morbidity of dental caries, also has benifit to neural excitatory transmission, phosphorus metabolism, parathyroid function, cellular enzymes system and reproductive process.But the harm that the too much absorption of fluorine produces animals and plants and human body is considerably beyond the not enough impact on HUMAN HEALTH of fluorine.Oil repellent is too high, can affect the Ca,P metabolism of human body, and the substance metabolism of human body and physiological function are got muddled, thus causes some fluorosis symptoms such as skeletal fluorosis, spot tooth, and fluorosis also can cause anaemia, leukopenia etc.Current various countries are according to the temperature of locality and the fluorine quantity of everyone every daily ingestion, formulate the national fluorine-containing standard of tap water (within the scope of 0.5-2.0mg/L), Drinking Water in China fluorine content standard is 0.5-1.0mg/L (GB 5749-2006), agricultural irrigation water quality standard (GB 5084-2005) is general area≤2mg/L, high fluorice region≤3mg/L.
China's water of high fluorine content has a very wide distribution, and relates to and about has 27 provinces, municipalities and autonomous regions.Report that China has in people's tap water of more than 700,000,000 that fluorine is more than 1.0mg/L according to National survey, HUMAN HEALTH in water of high fluorine content serious threat, especially oil well, coal bed gas well production water, and its fluorine content is generally greater than 5mg/L, must carry out except fluorine process before discharge.The defluorination method used at present is broadly divided into two large classes: fractionation and physical partition method.Fractionation is divided into again coagulant sedimentation, calcium salt precipitation method, lime phosphate process, chemical process and the electrochemical methods such as electrodialysis, electrocoagulation such as alkali-lime method, thermooxidizing magnesium processes.Physical separation method is divided into adsorption filtration method (bone black method, zeolite process, activated carbon method and activated alumina method) and ion exchange method (ion exchange column method, reverse osmosis method) two kinds.Due to easy and simple to handle, equipment is simple, working cost is low, current application is activated alumina method the most widely.But there is the defects such as fluorine removing rate is low, defluorinating agent consumption is large, processing cost is high, effluent quality is unstable to some extent in existing defluorination method, as the calcium salt precipitation method added amount of chemical such as lime, calcium sulfate, calcium chloride are large, be only suitable for the pre-treatment of high fluorine waste water; Electroosmose process to raw water quality require strict, facility investment is large, processing cost is high and eliminate other Hubeiwans; There is electrode passivation phenomenon in electrocoagulation, causes defluorination effect and economic performance to be deteriorated; Containing a large amount of dissolved aluminums in the water outlet of aluminium salt precipitation method, there is detrimentally affect to neural system; Molysite deposition method is comparatively strong to metal protection, and when flocculation operation condition is not good, often using water-band has light yellow; The bone black method recovery time is long, and bone black is soluble in acid, need control former water pH to reduce the loss of filtrate when practical application; Zeolite process loading capacity is low, dosage large, the process water yield is little; Activated carbon method requires higher to pH, generally has stronger adsorptive power when pH < 3, there is no adsorptive power during pH > 3; The maximum deficiency of ion exchange column method is the mineral substance removed in water, introduces amine substance; Reverse osmosis method processing cost is high, membrane module easily pollutes, work-ing life is shorter.Therefore, efficient, cheap defluorinating agent is developed and suitable technology of Fluoride Removal needs the problem of solution present stage badly.
