Also, the handling of the equipment is complicated. In addition, when a filter is installed in a pipe for solid-liquid separation and the liquid is pumped, the pressure increase due to blockage of the filter can cause problems such as damage to the pipe or filter section. There was a problem. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to reduce clogging of screens and filters in solid-liquid separators to facilitate maintenance and management, and to prevent damage due to clogging and the like.

A cross-flow type solid-liquid separator was constructed by interposing a cylindrical screen for allowing the liquid to flow out, a processing liquid receiver was provided on the outside of the screen, and a net member was provided at the outlet of the processing liquid receiver. Note that it is preferable that the cylindrical screen is placed in the vertical portion of the circulation pipe because the separated liquid can easily pass through the entire circumference of the screen.

The liquid flows out, enters the processing liquid receiver, and is further discharged from the outlet. Since only the liquid of the solid-liquid thus circulated is successively discharged to the outside through the screen, the solid-liquid concentration in the raw water tank becomes high. When the concentration reaches a certain level, the pump is stopped and the concentrated liquid is disposed of from the raw water tank to a designated location. Separation of solid and liquid is carried out by a screen, and since the cylindrical screen surface is parallel to the flow direction of the solid and liquid, the screen is less prone to clogging, and since the screen is washed by the flow of water, clogging can be further prevented. Furthermore, if the screen becomes clogged, the clogged portion can be cleaned by spraying water from the outside of the screen, or the screen portion can be easily replaced.

Since it is washed, it is less prone to clogging and is easy to maintain. In addition, it is easy to install and remove the screen from the circulation pipe, and its replacement is easy.
Cleaning the clogged area is also easy as all you have to do is spray water from the outside. Furthermore, if the screen becomes clogged and the screen is damaged due to the pressure of the solid liquid being pumped, the solids with large particle sizes will remain in the processing liquid receiver and will not flow out. The pump and on-off valve can be stopped and repaired based on the sensor signal that detects this, so the equipment can be operated safely.
