In generally, the operation reference for Sedimentation tank in waste water treatment plant, especially for sludge effluent, is controlled by results of laboratory analysis or sludge concentration meter, but is not controlled by on line data research.
The purpose of this research is to develop a technology and device for SS settling characteristic measurement, and is proved and continuously monitored the SS in sedimentation tank in Hsin-Tsu Industrial wastewater treatment plant, based on Beer-Lambert theory. The results of this research, shown SS automatic measurement system, not only offer the on line data of SS settling change, and effectively estimate the change trend of effluent waster water quality, but also offered the output on line information, such as average specific gravity, integrated settling weight distribution, settling velocity, retention time and effluent waste water… etc., is on purpose to adjust the process of sedimentation tank and pretreatment units, in order to upgrade the treatment capacity efficiency and system steady.
At this stage, most monitor equipments in market just could measure the one spot concentration of waste water quality. But we could get the variation of SS concentration at different depth, SS integrated weight distribution with the depth and settling velocity by means of results of calculation and Analysis. Moreover we could estimate the SS concentration of effluent by the results of this measurement. The capital and O&M cost of our system are cheaper than the existing equipments in market, and are beneficial to get more information and controlled by on line data. Therefore, the system is not only populous and acceptance for end users, but also is helpful for operation and pollution control in waste water treatment plant. |
