Two perforate centre positions, wastewater inlet are at the inwall of the central cylinder of intermediate cavity, and filter core import is full-gear, row
Dirty passage is closed state, and now source water enters inside filter core and filtered, and clear water is come together between filter core and case after filtering,
Exported by outlet pipe；When needing to clear up filter core, rotational handle, make in filter assemblies capping and a perforate of intake antrum bottom surface
The heart overlaps, and drain outlet is opened, and the clear water between filter core and case enters filter core, miscellaneous in screen wall and filter screen by accumulating in
Matter is flushed into blow-off pipe discharge；After filter gauze cleaning is clean, rotational handle can carry out the cleaning of next filter screen, until filter core
Full recovery is to normal operating conditions.The filter filter core can be backwashed under not stopped status and independent blowdown,
But backwash needs manual rotation's handle to send operation signal, and every time can only a filter screen backwashed.
The content of the invention
It is an object of the invention to overcome shortcoming present in prior art, there is provided a kind of sewage disposal device, the equipment
The sewage being passed through in screen pipe is subjected to separating and filtering, clear water is come together in case, and is pumped into backpressure flushing part, by movement
