Abstract
The present invention relates to a structural filter element for purifying water and a preparation method thereof. The structural filter element mainly takes high molecular material, such as polyethylene resin, or acrylic acid resin, or polyurethane resin or rubber, as base material, active carbon fiber, or active carbon, or molecular sieves, or diatomite is added, and the structural filter element is formed by pulverizing, mixing homogeneously, heating, plasticizing, moulding or extruding. The structural filter element for purifying water has the structure of filtering holes and adsorbing holes. The structural filter element can be used for treating purified water, impurities, such as heavy metals, pesticides, organic matters, etc. can be removed, and the structural filter element can have the functions of sterilization and disinfection.
Description
The present invention relates to structural filter element of a kind of usefulness of purifying waste water and preparation method thereof, relate to structural filter element of using in a kind of processing procedure of purifying waste water and preparation method thereof specifically, belong to water purified treatment field.
At present industrial wastewater, sanitary sewage, agricultural chemicals etc. are to causing severe contamination in the water source, though after water factory's purified treatment, can remove the part harmful substance, extremely low to heavy metal, agricultural chemicals and some organic substance clearance.Running water is in conveying, because the part pipe network is long neglected and in disrepair, the water tank of skyscraper setting loses in cleaning, and all can cause secondary pollution to drinking water, harm humans health for sterilization adds chlorine-containing disinfectant.For addressing the above problem, various types of water purifiers have been developed and have produced both at home and abroad, its material for core is generally selected the graininess active carbon for use, one or more active materials such as fiber-reactive charcoal, molecular sieve, directly be contained in these materials in the water purifier, can remove heavy metal, agricultural chemicals, organic matter though do like this, can not remove and degerm and sterilize.Because of bacterium can enrichment breeding on this class sorbing material.In order to sterilize, need ooze silver or chlorination to active carbon, add iodinate, this can feed water and bring secondary pollution.And in the water purifier as load porous ceramic filter element or through the porous polymer materials of sintering, hollow fiber filter membrane etc., though can intercept the part bacterium, but can not effectively remove harmful substances such as heavy metal, agricultural chemicals, organic matter, in a word, the structural filter element of using in the existing processing procedure of purifying waste water is unsatisfactory.
The objective of the invention is to design a kind of special filtering holes structure that possesses, the structural filter element of a kind of usefulness of purifying waste water of adsorption hole structure is to overcome the shortcoming and defect of above-mentioned various filter cores.
The object of the present invention is achieved like this: the structural filter element of a kind of usefulness of purifying waste water of the present invention, this filter core is made up of base material and additive, and described base material is selected from one or more the combination in polyvinyl resin, acrylic resin, ammonia ester resin, the rubber; Described additive is selected from two or more the combination in active carbon, NACF, molecular sieve, the diatomite; Above-mentioned base material and additive are through pulverizing respectively, mixing, heating, plasticizing, mold pressing or extrusion modling; It is characterized in that the raw material proportioning of above-mentioned base material and additive (percentage by weight, down together) is:
Base material: additive=40-60: 60-40.
The composition preferred substrates of this filter core is a polyvinyl resin, and additive is an active carbon fibre peacekeeping molecular sieve, and its proportioning is base material: additive=58-54: 42-46; NACF 32-34 wherein, molecular sieve 10-12.
The composition of this filter core also preferred substrates is a polyvinyl resin, acrylic resin and rubber; Additive is active carbon and diatomite, and its proportioning is base material: additive=45-49: 55-51; Polyvinyl resin 41-44 wherein, acrylic resin 1.5-2, rubber 2.5-3; NACF 44-41, diatomite 11-10.
Described rubber is nontoxic natural rubber or nontoxic synthetic rubber.
The preparation method of filter core of the present invention is characterized in that by following process preparation:
(1) selects materials and weigh by above-mentioned weight proportion;
(2), cross 200 mesh sieves with the base material raw material pulverizing;
(3) additive is pulverized, is crossed 200 sieves, and with base material powder mixing;
(4) the said mixture material is packed in the mould, extrusion modling, forming temperature is 150-240 ℃, promptly gets filter core of the present invention after the cooling.
Filter core forming shape of the present invention can be rectangle, cylinder or other shape; Can decide according to the structure of water purifier.
The present invention compared with prior art, it is a kind of structural filter element with the usefulness of purifying waste water of filtering holes structure, adsorption hole structure, the processing that it can be used to purify waste water can be removed impurity such as heavy metal, agricultural chemicals, organic matter.Can also degerming, sterilization.
The present invention is further described below in conjunction with embodiment:
Embodiment 1
(1) selects materials and weigh by following weight proportion;
Base material: polyvinyl resin 50Kg
Additive: NACF 30Kg
