The carrier rotating machine 100 of the present invention will be described with reference to FIGS. 1 to 10. First, referring to FIG. 1, the advanced sewage treatment facility consists of a distribution tank - anoxic tank - aerobic tank - sludge storage tank - settling tank - discharge tank. Although arranged, the carrier rotator 100 of the present invention is rotatably installed by being immersed in the aerobic tank, and is installed to rotate in the opposite direction to the inflow direction of the influent.

When the influent flows into the aerobic tank, the carrier rotator 100 rotates in the opposite direction to the inflow direction of the influent flowing into the aerobic tank, and eventually the influent flows backward while receiving the flow resistance by the carrier rotator 100 and rises up at the same time. The turbulent flow is formed while mixing, and the contact between the air and the organic matter contained in the influent water is more efficient with the microorganisms attached to the carrier.

On the other hand, a concentration sensor for measuring the concentration of the influent is installed at the inlet side of the aerobic tank. After detecting the concentration of the influent by the concentration sensor, the signal is transmitted to the control unit, and the control unit is A speed control signal is sent to the speed reducer of the driving means.

That is, when the concentration of the influent flowing into the aerobic tank is detected as high concentration, the rotation speed of the carrier rotator 100 provided with the composite carrier is increased, and when the concentration of the influent water flowing into the aerobic tank is detected as a low concentration, the rotation speed of the carrier rotator 100 equipped with the complex carrier is detected. Decrease speed control.

In this way, in a state in which the carrier rotator 100 rotates at high or low speed depending on the concentration of the influent, the influent flows inward through the passage (space between the support plates) formed in the carrier rotator 100, and at the same time the carrier rotator 100 of It flows into the inside through the inlet holes of the plurality of carrier units 112 disposed therein, and eventually the influent water permeates smoothly up to the composite carrier 200 filled in each carrier unit 112 .

At this time, even if the complex carriers 200 in the carrier unit 112 are subjected to an external force (vibration during rotation of the carrier rotator), they are inserted and installed inside the carrier unit body to maintain a firmly fixed state.

The sensing means 95 and 97 may be installed in four or more front, rear, left and right, and furthermore, may be installed to form a circular arrangement. It is preferable to install it so that

When the chain 94 installed as described above detects movement by the sensing means 95 and 97, it transmits data according to the sensed signal to the control unit 99, and the control unit 99 receives the transmission data and operates the carrier rotator. The rotational operation such as reducing or stopping the rotational speed may be adjusted, and the tension of the chain 94 connected to the sprocket 82 may be adjusted using a tension adjuster.
