Pressure filter operation rate measuring device of acid wastewater filtration equipment

摘要

The present invention relates to a pressure filter operation rate measuring device of a wastewater pressure filtration system that separates sediment sludge contained in a wastewater generated from a cold rolling mill and a plating plant, and simultaneously filters the wastewater. In the conventional acid wastewater pressure filtration equipment, which is provided with a secondary pH adjustment tank, and a sedimentation tank, a sludge storage tank, a pressure filter, and an adjustment tank are sequentially connected to the rear side, and a filtrate storage tank is provided on the outlet side of the pressure filter. Wherein, the inner center of the filtrate storage tank is provided with a diaphragm to guide the laminar flow into turbulent flow, the laminar flow portion of the filtrate storage tank is located a steel tube formed with a through hole on one side of the bottom for measuring the level of the filtrate The upper part of the steel tube by using bolts and nuts to maintain a predetermined gap between each flange Value was, the steel tube to the upper inner side of the hayeoseo form a measurement apparatus body through the respective flange and install a water level measuring apparatus installed in connection with the panel.
