Description
Technical field
The invention belongs to field of environment engineering technology, be specifically related to a kind of filter of removing impurity in the water, and in the application of the aspects such as emergency processing of environmental protection and heavy metal precipitation.
Background technology
In recent years, China's great environmental pollution accident that takes place frequently, especially heavy metal pollution incident.Guangdong Bei Jiang cadmium pollution incident in 2005 for example, Linyi, Shandong in 2009 arsenic contamination incident and Zijin mining industry copper in 2010 contamination accident etc.These contamination accidents have caused serious threat to urban water supply safety.
These contamination accidents in case happen suddenly, the harm that society, economy, environment are caused is difficult to thoroughly recover.With regard to heavy metal, emergency method is the precipitation method the most fast and effectively at present.But but there is the difficult problem of Separation of Solid and Liquid in this method; If as early as possible heavy metal precipitation is not separated from water body; The heavy metal that its influence that is vulnerable to water body pH has on the one hand consequently precipitated is got back to again in the water body, will face this huge engineering of desilting in the bed mud in river if deposit on the other hand.This shows that after heavy metal precipitation, realizing filtering fast is a step the most key in the emergency processing.Impurity in the sewage can be effectively removed in filtration, realizes Separation of Solid and Liquid, and is beneficial to subsequent treatment work.
In addition, burst natural calamities such as flood, earthquake have certain influence to water quality, also face the quick removal of impurity in the water, are main with turbidity and metal ion wherein.There are some researches show big flood make suspended material increase, reduced water transparency (Sheng Jianming, Fei Zhiliang, Ge Jiachun. big flood is to the influence of lake ecological environment. Nanjing Forestry University's journal; 2000,24:112～115), bring " hysteresis effect " (Luo Xianbao of heavy metal ion and to water quality impact; Wen Jun; Luo Dong is strange etc. and flood is coerced the influence and the Study on Risk Assessment of factor pair Thousand-Island Lake water quality. Chinese Ecological Agriculture journal, 2006,14 (3): 118～121).There is sample investigation to show after the earthquake that the turbidity accounting is heavy bigger in the defective index of water quality; And exist the phenomenon that ferrimanganic exceeds standard (Chen Zhi, Yue Yunyao, Zhang Ting etc. Jiangyou City source water testing result is analyzed after the earthquake. preventive medicine information magazine; 2009,25 (9): 734～735).
Filtration is a kind of effective water quality purification method.In filtering technique, traditional filter is the straight tube cylinder of filling filtrate, and wherein the most key is the selection of filtrate.With regard to filtrate, can be divided into the both surface filtration is main filtrate, for example filter cloth, filter screen, agglomerated material, powder etc.; With the filtrate that with the in-depth filtration is the master, for example solid particle or short fiber.(Fang Tunan; Pan Yuanqi. filter the theory and the progress on basis. chemical industry equipment and anticorrosion [J] .2001.3:2-7) at present the filter about heavy metal generally be directed against micro heavy solution, mostly used filtrate is the material with heavy metal ion generation physical-chemical reaction.For example the CN201020131025.2 patent discloses a kind of ceramic element filter, and this filter adopts active carbon and ormolu ceramic element pipe to drinking water, removes heavy metal ion through physical action; The CN200810089706.4 patented invention a kind of ion exchange material with adsorption function, this material is 2-17meq/g to the adsorption capacity of heavy metal ion.Then few to the filter of heavy metal precipitation specially.The filtering heavy metal deposition needs the filtrate only be fixed and through the physics crown_interception, and this filtrate can obtain the rate of filtration and filter effect preferably simultaneously, to adapt to the requirement of emergency processing.In addition, recurrent short flow phenomenon also influences filter effect in filter process, also need improve filter for this reason, can make it to combine better with filtrate on the one hand, and another side also can be avoided short flow phenomenon.
Summary of the invention
The technical problem that the present invention will solve provides a kind of modularization filter, and this modularization filter can better solve the contradiction of the rate of filtration and filter effect and the problem of the short-and-medium stream of filter process.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
Modularization filter of the present invention constitutes by holding water module (1), filtering module (2), water outlet module (3) and composite filter element (4).Concrete member and connected mode: hold water module top and be water-locator (5), upper end and hold water layer (6), be that filter core compacting snib (7), lowermost end are outer hybrid layer (8) near the bottom for water inlet.The filtering module upper end is outer hybrid layer (8) for interior hybrid layer (9), centre for filter core support compacting parts (10), lower end.Filter core support compacting parts (10) are united two into one by filter core support snib (11) and filter core compacting snib (7).Filtration water outlet module (3) is held water layer (12) and is filtered out the mouth of a river (13) by interior hybrid layer (9), filter core support snib (11), water outlet and forms.Between each module promptly by the chimeric one that is assembled into of inside and outside hybrid layer.Composite filter element (4) is filled in the inside and outside formed inner chamber of hybrid layer.Composite filter element (4) is sewed up by both surface filtration material and in-depth filtration material mechanical and is formed, the proper and interior side superimposed of filter core support compacting parts snib of suture (14).Composite filter element both surface filtration material is polypropylene (PP) filter cloth (15), the moisture absorption hardly of this material, and acid and alkali-resistance and common organic solvents.The in-depth filtration material is viscose staple fibre (16), and density is 1.50～1.52g/cm
3The filter core shape is complementary (as circular, square etc.) with size and filter inner chamber.
Filtering composite filter element of water outlet module filter core support snib place's placement when this device uses, chimeric then filtering module is positioned over another filtering module support snib place, chimeric more subsequently filtering module with second composite filter element again.Chimeric so layer by layer compacting filter core, but flexible combination are until needed filtering module number.The last chimeric water module of holding.To streaming, liquid to be filtered promptly held water layer by the filter upper end and flows into, and promptly filters out mouth of a river outflow by the filter lower end under this installed and is.
This device is to different process object; Can adjust filtering module flexibly; As filtering for heavy metal precipitation; Take two to five filtering modules according to heavy metal attribute and concentration are unusual, adopt three to four filtering modules, adopt three filtering modules for solid suspension SS advanced treating in the Sewage Biological Treatment is general for general suspension (like silt particle etc.).
