| 摘要 |
The present invention relates to a system (17) for real-time monitoring and/or controlling wastewater or sludge dewatering and/or thickening processes, said system (17) comprising a wastewater piping (13) comprising a wastewater inlet (1) and a concentrated wastewater outlet (18); at least one dewatering or thickening device (14), attached to said wastewater piping (13) between the inlet (1) and the outlet (18); at least one total solids measurement device (2, 8, 11), attached to said wastewater piping (13); at least one total suspended solids measurement device (3, 7, 10), attached to said wastewater piping (13) or a fluid outlet (9) of the dewatering or thickening device (14); an inorganic coagulant container (4) connected to said wastewater piping (13); a feeding valve (5) to control a flow of inorganic coagulant from said inorganic coagulant container (4) to said wastewater piping (13); and a control unit (15); wherein the flow of inorganic coagulant is adapted to be controlled to uphold at least a predetermined set point value (TDS1) in relation to the value measured by said total solids (TS) measurement device, and the value measured by said total suspended solids (TSS) measurement device. The present invention further relates to a method for controlling said system and the use of the system for monitoring and/or controlling a wastewater dewatering and/or thickening process. |
