In particularly, the present invention relates to a method for killing organisms in the course of conveying ballast water in ship, comprising applying a voltage with frequency of 400-40000 Hz between the anode electrode and the cathode electrode of the free radical generator, thereby forming strong ionization discharge of electric field strength of 250-600 Td between the anode electrode and the cathode electrode, ionizing, dissociating, and exciting O2 and H2O, or O2, processing into active particles comprising O3, OHnulland HO2, dissolving excitately to obtain free radical solution mainly consisted of OHnull, adding the free radical solution to conveying pipeline of ballast water, conveying for 2-20 s in the pipeline, thereby obtaining killing organisms of ballast water selected from the group consisted of bacteria, single cell alga, and protozoan. It is capable to kill harmful invading microorganisms in the course of transporting ballast water without leaving any residual chemical reagent. The bacteria, single cell alga, protozoan, spore and vibrio, are eliminated and decomposed into H2O, O2, and small inorganic salt. It has no pollution and discharge, therefore, it can solve the problem of environmental pollution. The apparatus of carrying out above method comprises medium-high frequency electric source, ejector, gas liquid dissolution separator, liquid-liquid mixer, residual free radical treater, wherein a free radical generator is installed between the said ejector and the input raw material gas. The present method is capable of improving the quality of ballast water and is simple in operation and inexpensive.

摘要： A process and system for the self-regulated remediation of groundwater situated beneath the surface of a contaminated ground site is herein proposed. The process includes the steps of selecting a ground site to be tested for potential contamination, extracting soil gas samples from interspersed locations within an underground soil layer, gleaning information from the extracted soil gas samples to both determine the extent of any contamination and delimit any specific area of contamination at the selected ground site, determining both an appropriate concentration of a preselected oxidant or oxygen-releasing agent within a solution and an appropriate flow rate of injection according to the determined extent of contamination, determining both an appropriate number of groundwater injection points and an appropriate spacing between the groundwater injection points according to the delimited specific area of contamination, and delivering the determined preselected oxidant solution under pressure into the groundwater within the delimited specific area of contamination via the groundwater injection points at the determined injection flow rate.

摘要： A water purification system and method suitable for use in swimming pools, spas, hot tubs, water storage tanks, wells and water cooling towers adds (i) an oxidizing agent, preferably granulated or caked chlorine, (ii) metal ions, preferably silver from a galvanic cell having a silver anode electrically connected to a cathode made from a metal of still higher electrochemical potential, normally platinum, and, optionally (iii) an algaecide, preferably chelated copper and/or phosphate-removing compound, and/or (iv) a phosphate-reducing compound, all in synergistic combination. The galvanic cell is preferably some tens of square centimeters in size and some tens of grams in weight, thereby liberating sufficient silver or copper ions so as to aid in treating a multi-thousand liter body of water, such as a swimming pool, for, typically under normal contamination, some weeks to months until the anode is consumed. Copper and/or silver ions liberated from the galvanic cell cooperate with oxidizing agent to suppress bacterial, fungal and/or algae growth, particularly when new supply of oxidizing agent ceases for a prolonged time, normally >2 days. The (i) amount of chlorine, bromine or other chemicals needed to maintain water quality is thus significantly reduced to the greatly enhanced comfort of bathers while the (ii) time during which recovery can graciously be made from an exhausted supply of oxidizing agent is usefully extended.
