REVERSE ANGLE PRECIPITATION APPARATUS HAVING REVERSE-STACK-FLOWING STRUCTURE

摘要

The present invention relates to an inverse gradient settlement apparatus having an inverse gradient stacking flowing structure, including a settlement tank into which raw water flows; a plurality of inverse gradient settlement plates which are installed and slope for the opposite direction of raw water current flowing in the settlement tank; a scrapper which is installed between the inverse gradient settlement plate and the bottom floor on the settlement tank to transfer sludge from the inverse gradient settlement plate to a sludge discharging hole on the settlement tank; a scrapper driving motor for rotating and agitating the scrapper; and a settlement plate connection part which connects the inverse gradient settlement plate to each other to supply raw water to the lower part of the inverse gradient settlement plate.
