Apparatus for analyzing and sampling of liquid effluents coming from an industrial installation.

摘要

To provide for the monitoring of liquid effluents discharged from an industrial installation, an apparatus is used which automatically takes a sample at regular intervals in a sampling system (22) and which immediately analyses a sample taken at the same time as the previous one in an analytical system (24). At each sampling, the apparatus measures the flow rate of the effluents in the discharge pipe (10) by means of a flow meter (32). In addition, the apparatus continuously monitors the opacity of the discharged effluents in an opacimeter (30). A microprocessor (34) fitted with a control keyboard (36) for the input of parameters and a printer (38) displaying the results provides for control of the apparatus and, if necessary, actuates alarms (42) and valves (16, 12) for shutting off the pipes carrying the incoming water (14) and those carrying the discharged effluents. <IMAGE>
