Patent TW-363946-B (TW)
Title: Combined continuous and intermittent aeration for wastewater treatment
Inventor: TZOU WEN-YUAN
IPC: C02F7/00
Filed: 1995-02-20
Granted: 1999-07-11
Abstract: The objective of this invention is to reduce the cost of chemicals and to control sludge bulking in aeration tank. The incoming wastewater is necessary to adjust pH value to neutralization before the organic wastewater was treated by an activated sludge process. However, the sludge bulking occurred frequently in activated sludge resulting in high SS (suspended solids) concentration and turbidity in effluent. The process combined a continuous aeration tank with an intermittent aeration tank in this invention is applied to a low pH wastewater which is not need to neutralize by NaOH and flew directly into the first stage aeration tank. The volatile organic acids were decomposed in this stage, the rest of organic pollutants were treated by an intermittent aeration tank which followed by a continuous aeration tank. The dissolved oxygen (DO) in the second stage is equal to zero during non-aeration periods to select microorganisms in terms of zoogloea bacteria rather than filamentous bacteria. The advantage of this process is to treat organic pollutants, to control sludge bulking, and to avoid a high pH in the final effluent.

Granted: 1999-12-11
Abstract: A television viewer can easily navigate programs which are grouped according to a common service provider or other grouping criteria by depressing the "channel up" or "channel down" buttons on a hand-held remote control. Programming services which are provided via one or more transmission paths are integrated, thereby allowing a viewer to successively select the grouped channels regardless of the broadcast signal, transmission path, frequency spectrum, transport stream and/or PID in which the channel is carried. Data is provided with broadcast signals to indicate broadcast address information which corresponds to a primary channel and one or more secondary channels of a channel group. A viewer can successively view the channels of the group while bypassing intermediate non-group channels. Grouped channels can thus be designated by a common channel designator such as a channel number. Goodwill and brand loyalty which has been built up over time in a local station channel number can be used to define a family of programs to maintain continuity as channels are added or dropped, or channel assignments of programming services are rearranged. A method for grouping a plurality of broadcast programming services which are provided in corresponding channels, comprising the step of: grouping a first plurality of said channels in a first channel group according to a desired first grouping criteria; said first channel group including a primary channel, and at least one secondary channel; wherein: a user can successively select the programming services corresponding to said first channel group according to a user control signal and data that associates said primary channel with a broadcast address of said at least one secondary channel.
