The invention relates to a sectional filter for discharging sludge and water for a culture pond, consisting of a main pipe body and an adjustable pipe set, the peripheral surface of the main pipe body is disposed with a plurality of through holes. The adjustable pipe set has a set of water level adjusting pipe provided on the outer peripheral surface of the main pipe body and a flow rate adjusting pipe provided inside the main pipe body, wherein the peripheral surface of the water level adjusting pipe is provided with an opening and the flow rate adjusting pipe is disposed with a plurality of through holes. Accordingly, the threshold water level for discharging sludge can be adjusted using the water adjusting pipe, and utilizing vertical displacement of the flow rate adjusting pipe to enable the through holes of the flow rate adjusting pipe and the through holes of the main pipe body to form relative position adjustment, the flow rate of discharging sludge can be flexibly controlled. Therefore, the design of
