By adopting the technical scheme, the sewage can be filtered layer by layer, so that the sewage is filtered more thoroughly.

Optionally, the upper end of the well lid is provided with a drawstring.

Through adopting above-mentioned technical scheme, be convenient for open the well lid, clear up the well is inside.

Optionally, the L-shaped pipe is made of steel.

By adopting the technical scheme, the steel material has better performance.

In summary, the utility model includes at least one of the following advantages:

1. the first filter plate, the filler, the second filter plate and the third filter plate can filter sewage layer by layer, so that the sewage can be filtered more thoroughly;

2. through setting up L type pipe and come to carry out automatic drainage to sewage to, improve the suitability of device.
