By arranging multiple partitions 120 in a staggered manner and having a channel between one end of the partition 120 and the box body 110, the sewage passing time is extended.
[0035] In a specific implementation, a plurality of limit strips 121 are provided on the side of the partition 120, and the filter screen 130 is inserted between two limit strips 121. By providing a plurality of limit strips 121, the filter screen 130 can be easily inserted between the two limit strips 121, which is convenient for disassembly and assembly.
[0036] Specifically, the clamping member 150 includes a clamping rod 151, a spring 152 and a movable plate 153. The filter screen 130 is provided with a connecting cavity 131. The clamping rod 151 is slidably arranged in the connecting cavity 131. The movable plate 153 is fixedly connected to the clamping rod 151 and slides through the connecting cavity 131. The spring 152 is arranged in the connecting cavity 131 and abuts against the movable plate 153. By arranging the clamping rod 151, the spring 152 and the movable plate 153, when disassembling, the movable plate 153 is pulled to move, and the movable plate 153 drives the clamping rod 151 to move and squeeze the spring 152.

[0042] The working principle of the pretreatment device for domestic sewage is as follows: when in use, sewage is introduced through the water inlet pipe 210, and the sewage first enters the filter frame 220. Larger dirt is filtered and retained in the filter frame 220 for centralized cleaning. The agent is added through the adding cylinder 240. Multiple partitions 120 are arranged in a staggered manner, and one end of the partition 120 and the box body 110 have a channel, which can extend the time for sewage to pass through the box body 110, so that the agent can fully exert its effect and ensure the agent treatment effect. When it is necessary to remove the partition 120 to clean the adhered dirt, the movable plate 153 is pulled to move, and the movable plate 153 drives the clamping rod 151 to move and squeeze the spring 152. The clamping rod 151 is away from the clamping groove 122 of the partition 120, so that the filter screen plate 130 can be removed. When installing, the filter screen plate 130 is inserted along the two limit strips 121 in the same way, and the elastic recovery effect of the spring 152 is used to push the clamping rod 151 into the clamping groove 122 to achieve connection, which is convenient for quick disassembly and replacement and improves efficiency.
