A water disinfection delivery treatment system first filters the supply by a particle and then a carbon filter. The partially treated flow is split in two and a first part passes through a first cutoff valve and is fed into a disinfection (iodine) chamber, filter or feeder via a flow restricter. The chamber output passes through a second solenoid driven cutoff valve. The second part is fed to a third cutoff valve and this valve's output is summed with the second valve's output and then fed into a holding tank. The tank retain's a volume such that the water remains therein for at least a period sufficient to permit a minimum 3 log reduction of pathogenic microbes. A final carbon filter is downstream of the tank as is a meter and dispenser. A method is also provided for delivering potable drinking water.

The invention provides a method for recovering gold from a printed circuit board of a waste mobile phone. The method comprises the following steps that the gold in a gold leaching liquid of the printed circuit board of the waste mobile phone is adsorbed by adopting an adsorbent so as to obtain gold-loaded carbon, wherein the adsorbent is selected from biochar or iodine-loaded biochar; and the gold-loaded carbon is subjected to desorption, and then a desorption solution is electrolyzed so as to obtain the gold. According to the method, after gold leaching is carried out on the printed circuit board of the waste mobile phone, the iodine-loaded biochar is adopted for adsorption, liquid gold is concentrated, then the gold can be recovered through electrolysis, meanwhile, the gold leaching liquid (iodine) can be recovered, so that the production cost can be lowered, and the resource utilization efficiency can be improved; modification is carried out on the biochar by using an ethanol solution of iodine so as to prepare the iodine-loaded carbon, so that the gold adsorption efficiency can be improved, and meanwhile, the utilization rate of the iodine can be increased; and the biochar prepared from agricultural waste is used for adsorbing the gold, so that the waste can be recycled, the production cost can be lowered, and the energy consumption can be reduced.

The invention belongs to the technical field of polymer material and the field of biomedical engineering, in particular relates to a preparation method for a biodegradable radioactive particle used for curing cancer. The method comprises the following detailed steps: the basic material of the radioactive particle with the needed shape is prepared by using a macromolecular biodegradable material with excellent biocompatibility according to demands; the obtained basic material of the radioactive particle is put into a 0.1 to 0.4mol/l surface modified liquid for dipping and generating aminolysis and carrying out grafting reaction; purified water is used for washing the grafted basic material for removing dissociative functional groups; the obtained basic material is put into a coupling agent liquid to dip for 1 to 2 hours and then is coupled; the obtained basic material is put into the liquid to dip for 12 to 24 hours and then washed to remove the dissociative functional groups; a radioactive isotope is used for replacing the iodine element in the basic material obtained by step (4); and a decoration film is collocated into a liquid and is coated on the surface of the basic material, thus obtaining the needed product. The degradation product is innoxious and harmless, and can be discharged outside the body by metabolism. The preparation method is simple and low in cost.
