  • Method of implementing association in Automatic Switched Optical Network (ASON)
    Publication number: 20070121635
    Abstract: A method of implementing association in an Automatic Switched Optical Network. When an initial node of the 1+1 protection service is outside the ASON, it associates the primary service and the slave service to realize 1+1 protection. This invention includes: a node of a first associated service acquiring path information of a second associated service from a node of the second associated service, and associating the second associated service to the first associated service according to the path information of the second associated service.

  • Activated sludge process for sewage purification
    Patent number: 5447633
    Abstract: In a two-stage activation plant, part of the activated sludge (sludge circuit (1)) from the first stage (11) is transferred to the second stage (12) and part of the activated sludge (sludge circuit (2)) from the second stage (12) is transferred to the first stage (11), so that mixed biocenoses are formed in both stages (11 and 12). The biomass to be denitrified from the first stage is transferred to the second stage by the sludge circuit (1) and the biomass to be nitrified from the second stage is transferred to the first stage by the sludge circuit (2), so that not only carbon compounds are decomposed but nitrogen compounds may be removed by nitrification and denitrification in both stages (11 and 12).
