A method for harmless disposal and resource utilization of resin desorption liquid generated in the ion exchange process is provided. Resin desorption liquid is channeled into an electrolytic tank, which is arranged with an inlet and an outlet; the anode and the cathode within the electrolytic tank are separately connected to a stabilized power supply; both the direct and indirect oxidation process and occurred at the anode can decompose the organic pollutants in the desorption liquid; with necessary replenishment of fresh regeneration agent, the treated desorption liquid can exert excellent performance in regenerating saturated resin; the recycled use of resin desorption liquid is therefore realized, which consequently avoids unnecessary waste of regeneration agent and reduces the final yield of the desorption liquid. This method is characterized by being convenient in operation, without addition of extra reagents, without secondary pollution, and suitable for the desorption liquid with wide pH variations.

Proposed is an oxidation electrode for water treatment. The oxidation electrode for water treatment includes a current collector, an intermediate layer disposed on the current collector, in which the intermediate layer is made of a metal oxide, and an electrode active material coating layer, in which the electrode active material coating layer includes an electrode active material in powder form. The oxidation electrode for water treatment has the advantage that it is stable because the degree of change in current over time is not large and has a high efficiency in removing organic substances in water to be treated.

The present invention relates to a portable water purification and sanitizing apparatus and method. Due to the limited size of the apparatus and its ability to utilize DC power, the apparatus can be transported and operated in remote areas across the globe. The apparatus and method generates electrolytic products of chlorine, hydroxide and ozone that are utilized to purify and sanitize water for human consumption.
