Description
Technical field
The present invention relates to the manufacture method of a kind of purifying equipment for running water and refining plant, relate in particular to a kind of manufacture method that can effectively remove filtration unit and the filtration unit of various bacteriums in the tap water.
Background technology
Contain objectionable impuritiess such as bacterium, heavy metal, gas with foreign flavor, pigment in the tap water, according to statistics, contain about more than 2000 kinds of compounds in the tap water usually, wherein kind is harmful more than 200.Water purifier is an a kind of ideal family water purifying plant, is used for tap water and purifies, and makes the tap water that is polluted and do not reach the safe drinking water standard after this water purifier is handled, and all can be greatly improved.Can effectively remove chlorine in the water, trichloromethane, agricultural chemicals, SYNTHETIC OPTICAL WHITNER, the chemical toxicant of harmful human body such as organism is sent out and heavy metal, eliminates peculiar smell.In the prior art, the preposition filtration unit of water purifier is provided with the two-stage filter core usually, and the first step is the cotton filter core of PP, and the second stage is the extruded activated carbon filter core, and described two-stage filter core is arranged on the water treatment path.Activated carbon promptly is found from earlier 1900s and can be used to use as water treatment.It is the carbon of a tool vesicular tissue, and these holes are exactly the surface-area that is used for increasing activated carbon adsorption impurity.The quality of the rerum natura of carbonization material and its starting material and treating processes has great relation.Activated carbon is that chemical substance is got in abutment surface vesicular tissue absorption, organic contamination source, heterochromatic, peculiar smell etc.Generally speaking, the activated carbon that volume is more little, its total body surface area can be big more, and adsorptive power also will be high more, but the crushing of its pipeline also can be high more.How the PP filter core is with adsorbing suspended impurity, particle, mud or the like in the water intaking.With micron (micron) is the fractionated standard, and commonly 1,5,10,20 microns are waited the production method of pore size filter ectonexine different densities by filter core bigger adsorptive power to be arranged.When selecting PP scrubbing filter core, must look use occasion and select different pore size filters.When the tap water flow was big, the adsorptive power of activated carbon filtration material was very limited, can not effectively remove the chlorine residue in the tap water, can not effectively remove the heavy metal in the tap water; After the adsorptive power of activated carbon filtration material reaches capacity, must change the activated carbon filtration core, otherwise just can't play a role in filtering, and frequently change the activated carbon filtration core, will use to the user makes troubles, and increases use cost.Simultaneously, cotton filter core of PP and common activated carbon filtration material all can not suppress the growth of bacterium, and described two-stage filter core is not changed for a long time, can cause secondary pollution on the contrary, and bacterium is how much multiples to be increased.In order to reach the antimicrobial purpose, existing treatment process is that the extruded activated carbon filter core is dipped in Silver Nitrate and the rare nitric acid mixing solutions, after the drying, silver ions be physical adsorption on the extruded activated carbon filter core, can have biocidal efficacies, yet, in a single day described extruded activated carbon filter core is arranged on the water treatment path, silver and nitric acid all can be separated out, and silver is heavy metal, and is harmful, nitric acid is separated out becomes nitrite, and life-time service can be carcinogenic.
