Example 1
The present embodiment provides an apparatus for filtering contaminated water, as shown in fig. 1, which includes a tank 10, a pump 80, a controller 60, and a driving device 70 for driving the prefilter 40 to rotate. The primary filtering group comprises 3 primary filtering devices 40 which are arranged at intervals in the tank body 10, namely a first primary filtering device 40a, a second primary filtering device 40b and a third primary filtering device 40 c. Referring to fig. 2, the primary filter 40 is provided with a flow passage 41 communicating both sides.
A flow stabilizer 20, a rectifying device 30, a primary filtering group and an oil gathering device 50 are sequentially arranged in the tank body 10 along the water flowing direction; the tank 10 is provided with a medium inlet 11 at a sewage inlet end and a drain outlet 13 at a sewage outlet end. A sludge discharge port 12 is arranged at the bottom of the tank body 10 and at least between two adjacent primary filtering devices 40.

A first spring (not shown) is arranged between the prefilter means 40 and the tank 10, said first spring tending to force the prefilter means 40 to rotate in the direction of the angle set at the maximum. Wherein, the first spring is preferably a torsion spring sleeved on the pivot shaft; and a limiting block for limiting the swing angle of the primary filtering device 40, namely the maximum and minimum included angles.

In the tank 10, a second sensor 62 is disposed between the preliminary filtering device 40 and the oil collecting device 50, and is used for detecting the water quality after the preliminary filtering treatment.
The controller 60 is connected to the first sensor 61, the second sensor 62, the pump body 80, and the driving device 70, respectively. The controller 60 adjusts the flow rate and flow rate of the sewage through the pump body 80 according to the detection results fed back by the first sensor 61 and the second sensor 62, and controls the inclination angle of the flow channel 41 of the prefiltering device 40 through the driving device 70, so that the prefiltering speed and effect of the sewage can be automatically adjusted according to the specific conditions before and after sewage treatment, and the sewage treatment speed is increased as much as possible under the condition of ensuring the final excellent treatment effect. For example, when the degree of contamination of the wastewater entering the tank 10 is high, or the water quality detected by the second sensor 62 after primary filtration exceeds a predetermined fluctuation range, and the water quality after primary filtration has a large peak value and exceeds a predetermined threshold value, the controller 60 increases the inclination angle of the flow channel 41 of the primary filtration device 40 by the driving device 70, so that the fluctuation range of the water flow passing through the primary filtration device 40 is increased, and the flow rate and flow rate of the wastewater are reduced by the pump 80 until the water quality detected by the second sensor 62 reaches a predetermined standard. When the degree of contamination of the wastewater entering the tank 10 is low, the flow rate can be increased by controlling the pump 80, and the inclination angle of the flow channel 41 of the prefilter unit 40 can be reduced by the driving unit 70, thereby increasing the wastewater treatment rate.

When the detection result fed back by any one of the second sensor 62 and the third sensor 63 has a peak value and is out of the set range, the controller 60 increases the inclination angle of the flow passage 41 of the priming device 40 through the driving device 70, so that the fluctuation amplitude of the water flow passing through the priming device 40 is increased, and the flow rate of the sewage are reduced by the pump body 80. When the degree of contamination of the wastewater entering the tank 10 is low, the flow rate can be increased by controlling the pump 80, and the inclination angle of the flow channel 41 of the prefilter unit 40 can be reduced by the driving unit 70, thereby increasing the wastewater treatment rate.
