Abstract: A method for treating highly concentrated resin-desorption liquid generated from wastewater deep purification, including channeling the highly concentrated desorption liquid generated from anion exchange resin treatment through a nanofiltration membrane, the liquid being separated into nanofiltration permeate that can be reused as the desorption agent and highly concentrated nanofiltration retentate; adding a coagulating agent to the highly concentrated nanofiltration retentate to generate coagulation-precipitation; subjecting the supernatant formed after the coagulation-precipitation process to Fenton oxidation or ozone oxidation; after the reaction, adding to the liquid an alkali solution for further coagulation-precipitation; then channeling the liquid so treated back to the biochemical system of biochemical effluent treatment for further biodegradation is provided.

Abstract: A system and method for real-time network communications provides a session identifier as a public key for group communication between clients, and provides a channel identifier representing a private key for each of a plurality of clients. The channel identifier includes client-specific attributes, which function to indicate grouping criteria for the group communication. A dynamic communication link is created over a network between a client and a service based upon the public and private key combination such that group communication is enabled based upon the attributes of the private key and the public key. Communications are translated using a translation service which employs the attributes associated with the private key and the public key combination to provide response information in a designated language to enable multi-lingual real-time communications.
