Description
Technical field
The invention belongs to the water treatment technology field, relate in particular to the organic rare earth porcelain sand filtration of a kind of removal pellet and preparation method thereof.
Background technology
At present, Chinese face is being led serious water quality crisis, and water pollution problems constitutes a serious threat.The complex genesis of China's water pollution problems, large in number and widely distributed, pollutant kind is many, load is high, has aggravated the rare degree of Chinese water greatly, and threatens the public's healthy and standard of living, causes the huge social financial loss.From beginning in 1999, Chinese city sanitary sewage quantity discharged begins to surpass discharged volume of industrial waste water, in the agricultural production process, the chemical fertilizer usage quantity is soaring year by year, not only fail grain yield is improved accordingly, and make constantly the increasing the weight of of rural area pollution of area source in the eyes, and environmental quality is produced the increasing influence of influence, some areas groundwater pollution is serious day by day, and water pollution accident enters prone period occurred frequently.According to statistics, 3988 of water pollution accidents just take place in 2004-20011.Especially the great water pollution incident because of illegal blowdown of enterprise and accident initiation also is to take place in succession, and wherein comparatively great typical event is the pollution incident of preserved egg river, Guangdong Bei Jiang cadmium pollution incident, Hun River Fushun, Liaoning section water quality phenol concentration over-standard incident, Hongsuihe River, Guangxi swan section water pollution incident.On February 20th, 2009, Yancheng, Jiangsu at the title that " hundred rivers all " are arranged, because the west of a city water factory that supplies water to the urban district, more river factory to be subjected to volatile phenol compound polluted, Yancheng on July 23rd, 2009, tap water water source, Chifeng City, Inner Mongol well is flooded by heavy rain and causes waterhead area contaminated.Occurring symptoms such as diarrhoea, vomiting, dizziness, heating after having at least more than 4300 signature because of drinking public water supply goes to see a doctor.The Chifeng this beyond the Great Wall the small city also should this overnight " well-known " domestic and international.This shows that water surrounding and our human beings'health are closely bound up, the organism in the removal water is to ensureing HUMAN HEALTH significance again.
At present, removing organic water technology mainly contains: " coagulation-precipitation-filtration " technology, air stripping method, sterilization and disinfection technology, carbon source technology, biologic treating technique, ion exchange technique, membrane separation technique and photo chemistry technology treatment technology or the like.These water technologies can make the control of the organic content in the water reach higher index.But be used to handle various industrial sewages, industrial water purification, city tap-water, municipal effluent and family expenses pure water now, the soft filtering material is to make the traditional filtrate of quartz sand, gac and hard coal or the like, there is the problem into following aspect in it: voidage is smaller, adsorption time is too short, lost efficacy easily and obstruction, than being easier to wearing and tearing, have only work-ing life about 1 year.
Summary of the invention
The purpose of this invention is to provide the organic rare earth porcelain sand filtration of a kind of removal pellet and preparation method thereof, to overcome present prior art above shortcomings.
The objective of the invention is to be achieved through the following technical solutions:
The organic rare earth porcelain sand filtration of a kind of removal pellet comprises the raw material of following parts by weight: rare earth 10-12, viscosity loess 25-35, porcelain sand 40-60, calcium carbonate stone powder 9-16, binding agent 2-5;
Pure Silicon Metal content 〉=0.01 in the described rare earth, Pure Silicon Metal are at least a in the polysilicon; Binding agent is made by following weight percent raw material: polyethylene 0.5-2%, gelatine 0.5-2% and silica gel 97-98%.
The preparation method of the organic rare earth porcelain sand filtration of the described removal of embodiment of the invention pellet may further comprise the steps:
1) takes by weighing rare earth, in the rare earth that takes by weighing, add properties-correcting agent, properties-correcting agent is one or more in talcum powder, silicon-dioxide and the alpha-crystal form Beta-crystalline polyacrylic, has antireflective effect, can improve toughness of products and improve heat-drawn wire, properties-correcting agent can allow rare earth increase the content of Pure Silicon Metal after interpolation, is beneficial to that there are more gaps the inside behind finished product, better absorbs the heavy metal of sewage the inside;
2) raw material soaking that configures of step 1) after 1-2 hour, is directly added porcelain sand and is fermented in water, the normal temperature bottom fermentation, and fermentation time is 1-2 hour, makes rare earth and the abundant combination of porcelain sand;
3) step 2) add calcium carbonate stone powder, viscosity loess and binding agent in the raw material of handling well, then through being machined to form the spherical shape body that diameter is the 2-4 millimeter;
4) the spherical shape body of step 3) being made is put into the kiln of fire porcelain, through 200-300 degree high-temperature firing, fires the naturally cooling postforming 1 hour.
Beneficial effect of the present invention is:
1, spherical surface, filtrate body internal pore are evenly distributed, and voidage is big, and antifouling property is good, than traditional quartz sand, and gac, zeolite filtration advantages of good adsorption effect 8-15 times, water is generally 15-20m by the speed of filtrate
3/ h, the bed head loss is little, can reduce the filter tank height, saves power consumption and capital cost;
2, uniform particles is regular, easy cleaning, and back washing strength is generally 12-20l/m
2.s, wear away for a short time, can use repeatedly, can reach work-ing life more than 8 years; Compare quartz sand and gac, the water loss of back flushing of the present invention can reduce 30-50;
3, the pore volume area specific surface area in the filtrate is big, and holding filth capacity is big, is generally 9-10kg/m
3, be 5 times of carbon leaching material;
4, corrosion-resistant, acid and alkali-resistance does not run off, pollution-free, and no stripping nuisance guarantees water conditioning;
5, the adsorption effect of filtrate is 5 times of gac.
