In the above suspension treatment device, the height of the water outlet is lower than the height of the weir plate.
When the supernatant in the sewage storage part highly reachs the weir plate, liquid flows into supernatant discharge portion through the weir plate, and when the height of the liquid in the supernatant discharge portion highly reached the height of delivery port, the supernatant was discharged from delivery port department, and sewage in the header tank has carried out twice in sewage storage part and supernatant discharge portion respectively and has depositd and once filtered through the weir plate, has reduced the suspended solid content in the supernatant of discharging for the supernatant is cleaner.
In the above apparatus for treating suspended matter, the weir plate has a plurality of water flowing grooves at positions opposite to the water outlet.
Supernatant in the sewage storage part flows to the supernatant discharge part through the water flowing grooves on the weir plates, and the water flowing grooves have a filtering effect on the supernatant to block suspended matters in the supernatant in the sewage storage part.
In the above apparatus for treating suspended matter, the flume has an inverted triangle shape.
The water flowing grooves in the shape of the inverted triangle are connected together to form a height fluctuation shape, the supernatant flows to the supernatant discharging part through the inverted triangle-shaped low-lying part, and suspended matters in the supernatant are blocked in the sewage storing part by the inverted triangle-shaped bulge part, so that the supernatant is filtered.
In the above-described suspended matter treatment apparatus, the length of the sewage storage portion is longer than the length of the supernatant discharge portion. The weir plate divides the water collecting tank into a sewage storing part and a supernatant discharging part, and the length of the sewage storing part is 4-5 times of that of the supernatant discharging part, so that more sewage is precipitated in the sewage storing part, and the precipitated sludge can be treated by a sludge recovery pump.
In foretell suspended solid processing apparatus, the header tank is the back taper structure of narrow down wide to conveniently concentrate the sediment to the mud in the supernatant, be convenient for retrieve.
In foretell suspended solid processing apparatus, be located in the header tank the both sides of weir plate all are equipped with the mounting plate, form the draw-in groove between the mounting plate, the weir plate sets up in the draw-in groove, the weir plate with draw-in groove clearance fit. The weir plate is in clearance fit with the clamping groove, and the weir plate can be pulled out from the clamping groove to be replaced when being damaged in the use process.
