摘要： The present invention relates to a preparation method of La(OH)3 nanorod/walnut shell biochar composite material (LN-WB), comprising the following steps: putting walnut shell powder into a crucible and pyrolyzing and carbonizing in a muffle furnace at 350° C. to 450° C.; after the pyrolysis is completed, grinding and sieving the obtained biochar, and then repeatedly washing with deionized water; drying the washed biochar for later use; putting an appropriate amount of biochar into the deionized water to form a turbid solution; simultaneously dropwise adding LaCl3 and NaOH to the above turbid solution by using a peristaltic pump; and allowing the obtained mixture to stand at room temperature for 20 to 30 h, washing and drying for later use. The present invention successfully prepares a La(OH)3 nanoparticle-loaded biochar composite material through a simple synthesis technology.

摘要： An object of the present invention is to provide a water purification filter comprising activated carbon as a filtration material and a biodegradable polymer as a binder component, which water purification filter has a filtration flow rate sufficient for practical use as a pot-type water purifier while maintaining a certain free residual chlorine filtration capacity, and has a certain degree of hardness and excellent handleability. Provided is a water purification filter obtained by winding a nonwoven sheet containing fibrous activated carbon and a heat fusible core-sheath composite fiber and then heat fusing the sheet, wherein the heat fusible core-sheath composite fiber includes a sheath portion containing a biodegradable polyester resin having a melting point of 80 to 140° C. and a core portion containing a synthetic resin having a melting point at least 20° C. higher than the melting point of the biodegradable polyester resin, and wherein the water purification filter has a density of 0.12 to 0.30 g/cm3 and a specific surface area of 500 to 1800 m2/g.

摘要： An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system and a recirculation loop to the dilution reservoir for enhanced mixing of the dilute concentrate. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.
