By setting the adjusting screw 306 and the floating ball 307 and the adjusting screw 306 floating on the surface of the sewage, it is convenient to adjust the positions of the intercepting plate 302, the first oil filtering plate 303 and the second oil filtering plate 304 according to the water level of the sewage, so that the intercepting plate 302, the first oil filtering plate 303 and the second oil filtering plate 304 are always between the upper and lower of the sewage liquid level.

[0027] Working principle: When a sewage treatment and discharge device is in use, in the initial state, first, the sewage inlet 103 and the sewage outlet 104 are arranged at both ends of the treatment tank 1. The first partition plate 2 and the second partition plate 201 fixedly connected in the treatment tank 1 divide the internal cavity of the treatment tank 1 into three parts, so as to perform three-stage treatment on the sewage as required. And an intercepting plate 302, a first oil filtering plate 303 and a second oil filtering plate 304 are connected to the limiting rod 301 fixedly connected inside the treatment tank 1, and a floating ball 307 is installed at the top of the adjusting screw 306 arranged on the intercepting plate 302, so as to enable the first oil filtering plate 303 to still be between the liquid levels when the liquid level changes;
[0028] When it is necessary to intercept and filter the oil on the surface of sewage according to the change of liquid level, first, the sewage enters the treatment tank 1 from the sewage inlet 103. After reaching a certain liquid level in the treatment tank 1, it contacts the floating ball 307 and drives the floating ball 307 to move accordingly according to the liquid level height by buoyancy. Since the adjusting screw 306 connected to the bottom of the floating ball 307 is connected to the intercepting plate 302 through the adjusting nut 305, when the floating ball 307 rises and falls with the liquid level, the intercepting plate 302, the first oil filtering plate 303 and the second oil filtering plate 304 also rise and fall according to the liquid level, so that the intercepting plate 302 is always between the liquid surface. Because the density of oil is small and it floats on the water surface, the first oil filtering plate 303 and the second oil filtering plate 304 can effectively intercept the oil. This device is convenient for intercepting and filtering the oil on the surface of sewage according to the change of liquid level.
