Abstract
The invention discloses structural filter cores and specifically relates to a structural filter core for removing carbon tetrachloride from drinking water and a preparation method thereof. In the preparation process of the structural filter core, various raw materials are weighed according to the mass percent the original formula and are mixed and stirred to be even; a cationic surfactant is mixed with the raw materials of the original formula according to a mass ratio that 1-5g of the cationic surfactant is added in per kg of the raw materials, and stirring is carried out for 10-30min; and a mixture is put in a honeycomb mold, molded after being sintered at high temperature, and demolded after being cooled by airing, and then, the porous honeycomb structural filter core with prescribed pore diameter and porosity factor is obtained. The structural filter core not only purifies the drinking water, but also avoids the injury to human bodies arising from excessive carbon tetrachloride in the drinking water, thereby being very applicable to the treatment of drinking water at home terminals. Proved by test, the structural filter core has a ratio of over 99.9% in the removal of the carbon tetrachloride in the drinking water.
Description
Technical field
The present invention relates to a kind of filter core, relate to a kind of filter core of removing carbon tetrachloride in the drinking water and preparation method thereof specifically, belong to water purification treatment technology field.
Background technology
Carbon tetrachloride is a conventional sense standard important among the GB5749-2006 " drinking water sanitary standard "; Be industries such as chemical industry, medicine, agricultural chemicals raw material and solvents commonly used; Output and consumption are all very big; Increased the weight of the pollution that carbon tetrachloride causes water quality, carbon tetrachloride has the volatility and the lipides solubility of height, thereby is prone to by skin, mucosal absorption human body worked the mischief.And excessive carbon tetrachloride has carcinogenic, teratogenesis, mutagenesis in the Drinking Water, and long-term drinking is excessive contains the carbon tetrachloride drinking water and can produce human body and have a strong impact on.Up to the present, research remove the low concentration carbon tetrachloride drinking water technology seldom, Related Experimental Study is also less relatively, the treatment technology that can make the discharging of low concentration carbon tetrachloride reach " drinking water sanitary standard " almost is blank.
At present, the improvement technology of removal carbon tetrachloride has physics method, chemical method, bioanalysis.Physical treatment process or result and discharge standard are far apart, or cost is too high and be difficult to promote the use of; Chemical method is simple usually; Chemical oxidization method and chemical reduction method all have removal effect preferably to the carbon tetrachloride in the waste water, and bioanalysis also has certain treatment effect, especially in the laboratory; Certain micro-organisms shows the stronger degradation capability of carbon tetrachloride; But in the biological wastewater treatment facility of long-time running, carbon tetrachloride causes the microbial degradation performance to descend, thereby causes treatment facility normally not move; Photocatalytic oxidation is used for the organic chlorine water of advanced treating, is the comparatively active direction of research both at home and abroad, the carbon tetrachloride of this method in can degradation water, but reaction rate is less, and the reaction time is longer, and employed catalyst is except Ti0
2Outside relatively inexpensive, its catalyst is comparatively expensive, and has problems such as preparation complicacy, recovery and activation difficulty.
Summary of the invention
The present invention is under the jejune situation of treatment technology of low concentration carbon tetrachloride in existing novel drinking water, the problem of influence with high costs to existing a series of treatment technologies, that reaction rate is little and clearance is low and the filter core designed and developed.
