Abstract: PURPOSE: A wastewater treatment system that has two contact aeration steps is provided to meet environmental guidance, in which discharged water from waste sources should be at least 10ppm or less in BOD(Biochemical Oxygen Demand) & SS(Suspended Solid) respectively. In the system, the first and the second aeration tanks have contact media therein for fixing microorganism, and the volume of second aeration tank, which is installed to retreat residual BOD & SS from the first tank, is about 1/10 compared with that of the first tank. CONSTITUTION: Wastewater flown through a flow pit(3) and a flow equalization tank(2) runs into the first contact aeration tank, wherein retention time is about 22 to 26 hrs. and 30 to 80 m/m¬3 of contact media is installed therein. The first contact aeration tank is preferably partitioned into 2, 3 or more chambers for releasing shock-load, and a diffuser is installed to prevent clogging and consequential corruption at regular intervals. BOD & SS value of discharged water from the first contact media respectively below about 20ppm. After precipitating suspended solids in the first sedimentation tank(5) at the rate of 30 m¬3/m¬2-day, wastewater flows into the second contact aeration tank, wherein retention time is about 1 to 3 hrs. and 100 to 400 m/m¬3 of contact media is installed in front of the diffuser(13). The diffuser occasionally generates high-compressed air bubbles for separating microorganism from clogged contact media, and separated microorganism is removed by using a pump(14) after being collected.

A mask for an additional information burying is formed. The addition information is buried by use of the mask in the variation range of the frequency. The frequency-converted audio data, at which the additional information is buried, is reverse-converted into the audio data. In order to detect the additional information buried at the audio data, the audio data is converted into a frequency. A mask for a synchronous detection is generated from the frequency-converted audio data. The additional information is detected by use of the mask for the additional information detection.

Abstract: PURPOSE: A CSM(Cell Site Modem) testing apparatus in a backward CDMA channel and a test data generating method are provided to increase a reliability and a stability of a channel card by generating a test data to use it as an input data of a test circuit, constructing a white Gaussian noise generating circuit and obtaining a signal-to-noise ratio with an output signal of the White Gaussian noise generating circuit and the test data. CONSTITUTION: A pattern and a speed of a data to be tested are determined, and in this respect, a data of a speed of 1200bps is preferably selected to reduce a burden to a RAM(S1). A quality indicator is added to the data to be tested having a data speed of 9600bps and a 4800bps(S2). The reason for adding the quality indicator only to the 9600bps and 4800bps data is to slow the speed of substantial information data as the amount of the actual data becomes small. A tale bit of 8 bit of every 0 is added to the data(S3). The data is convolution-coded to correct an error generated due to a noise and an interference in a radio interval of the data(S4). A code symbol repetition is performed with the data, one of which is actually transmitted(S5). The data is read to perform a block interleaving. This is to make random a burst error, and the data is recorded in the block interleaver in a line unit and read in a column unit(S6). One of 64 modulated symbols is corresponded to every 6 code symbol for the data(S7). It is determined each data is to be transmitted by using the data transfer rate of a frame and a part of the code for the data(S8). A long code is generated for the data determined to be transmitted(S9). The long code is orthogonally spread to complete a test data(S10).
