In the utility model, the sewage is guided to the sludge storage area 8 formed by the inclined screen plate 7 through the water guide slope 6 on the partition filter screen 2; the sewage enters the circulating water tank 1 from the top inlet pipe 4 and enters the left sludge storage chamber 1a through the water guide of the water guide slope 6; due to the water guide effect, the sewage entering the left sludge storage chamber 1a can form a sewage fluid in the left sludge storage chamber 1a; the sewage fluid enters the sludge storage area 8 along the bottom of the left sludge storage chamber 1a; under the blocking effect of the inclined screen plate 7, the sludge in the sewage is filtered and retained in the sludge storage area 8, so that the sludge is concentrated and the sludge discharge is facilitated; the sludge can be discharged by starting the sludge pump, and the sludge discharge efficiency is improved.

[0019] As shown in Figure 1 and Figure 2 In order to improve the flowability of the sewage initially entering the circulating water tank 1, in the utility model, the water guide slope 6 is located at the upper half of the partition filter screen 2, the submersion degree of the water guide slope 6 in the circulating water tank 1 is reduced, the water guide stroke is increased, and the water guide slope 6 is fixedly arranged relative to the partition filter screen 2.
