Title:
PRESSURE/DENSITY-TYPE WATER LEVEL MEASURING MODULE
Document Type and Number:
WIPO Patent Application WO/2019/083228
Kind Code:
A1
Abstract:
Disclosed is a pressure/density-type water level measuring module, which measures the pressure and the density for each water level in an anaerobic digestion tank so as to precisely measure the water level inside the digestion tank according to measurement values of the pressure and the density for each water level and to regulate the water level inside the digestion tank. The pressure/density-type water level measuring module comprises: a pressure/density measuring unit provided at the side of the anaerobic digestion tank so as to measure the pressure of waste water flowing into the anaerobic digestion tank at a plurality of measurement points having different heights from the bottom surface of the anaerobic digestion tank; and a control unit for individually calculating an average density at the plurality of measurement points on the basis of the measurement values having been received from the pressure/density measuring unit, and allowing the waste water to flow into or be discharged from the anaerobic digestion tank on the basis of the calculated result, thereby regulating the level of the waste water flowing into the anaerobic digestion tank. Therefore, the pressure and the density inside the digestion tank are accurately measured such that the water level of the digestion tank is constantly regulated and maintained, thereby enabling organic solid materials to be prevented from flowing out or being withdrawn, without being properly processed, by the death of microorganisms. In addition, hydraulic retention time and the retention time of the solid materials can be constantly maintained according to the accurate measurement of the water level in the digestion tank, thereby enabling convenience to be provided in the operation and management of the digestion tank.
