Abstract:

A biologically active reactor system for the treatment of wastewater comprises one or more submerged denitrification reactors having coarse media particles and a fixed biological film comprising biologically anoxic active microorganisms. One or more submerged aerated filters are in fluid communication with the one or more submerged denitrification reactor, the submerged aerated filter comprising coarse media particles and a fixed biological film comprising biologically aerobic microorganisms for oxidation of organic matter. One or more deep bed denitrification filters for removal of suspended solids and denitrification of oxidized nitrogens are in fluid communication with the one or more submerged aerated filters, the deep bed denitrification filter comprising fine media particles of less than 6 mm. Effluent from the submerged aerated filter is recycled to the submerged denitrification reactor for pre-denitrification prior to being piped to the deep bed denitrification filter. During the method, wastewater influent along with treated effluent from the submerged aerated filter is fed to a submerged denitrification reactor.

Abstract:

A padding protective arrangement for furniture includes an elastic connective member and a plurality of cushioning pads. The elastic connective member has first and second end connecting portions, and a connector provided on the first end connecting portions. Each of the cushioning pads has a thickness larger than that of the elastic connective member, and a through mounting slot formed on the cushioning pad, wherein the elastic connective member is arranged to penetrate the cushioning pads at the respective mounting slot in such a manner that the first and the second end connecting portions are detachably connecting with each other by the connector to define a cushioning loop within the elastic connective member and the cushioning pads, wherein the cushioning loop is arranged to fittedly encircle a rim portion of the furniture for providing a cushion effect to absorb shock when a user accidentally hits the rim of the furniture.
