摘要： PURPOSE:To secure the proper cleaning work and thus to increase the working efficiency by detecting the light volume change caused by the soil at the optical path forming part of the optical detection system and then a comparison is given between the detection signal and the reference signal to control the cleaning cycle at the optical path formation part. CONSTITUTION:Piston 36 is lowered down to the area of lower side H than the optical paths of projector 33 and receiver 34 is order to measure the soil of transparent inner cylinder 30 of the measurement tube. Thus the light sent from projector 33 enters receiver 34 via the sludge water. This measurement signal is compared with the reference signal sent from reference value setting circuit 43, and the cleaning cyclic signals are cleassified into (a)-(e) according to what signal level of the straight line (b) the difference signal is positioned at. Arithmetic circuit 45 supplies the cleaning end signal to control circuit 46 via the difference signal of comparator circuit 44 and also gives adjustment to the cleaning cycles of timer part 48 like (a)-(e) in accordance with the scale of the difference signal. In this way, the proper cleaning is given to increase the working efficiency.

摘要： PURPOSE:To find the concentration of floating matters of activated sludge (MLSS) by measuring the volume (SV) of a sludge precipitation part and the concentration (D) of the sludge after standing still for a prescribed time in a measurement pipe and multiplying said measured values. CONSTITUTION:A sludge precipitation part 21 is formed in a SV measuring pipe 5 and ultrasonic waves are projected successively from the lower side ultrasonic transmission element 40 by controlling an oscillation circuit 45 by a controlling circuit 44. Then, the height of the sludge precipitation part 21 is measured by deciding the intensity of the ultrasonic waves received by a reception element 41 through a level deision circuit 43 and the SV value is found through a conversion circuit 46. The ultrasonic waves are projected from one of transmission elements 40 located lower than a precipitation boundary face 23 and the concentration is measured from the intensity of the ultrasonic waves received by the element 41 through a sludge concentration measuring circuit 47. The SV(%) value and precipitated sludge concentration D(%) are inputted into a multiplication circuit 49 and (SV)XD=MLSS(%) is found.

摘要： PURPOSE:To measure a precise sludge capacity and sludge settlement property by measuring the detecting result obtained every scanning while comparing with the detecting result before the scanning. CONSTITUTION:When the light source 14b corresponding to the position exceeding the precipitating part 28 is scanned, the transmission light amount larger than the light amount absorbed by the precipitating part 28 from the light sources 14a-14b-1 and transmitting therebefore is detected by a photoelectric converting device 15. The corresponding electric signal is discriminated by a discriminating circuit 17 as a signal 1 and fed to the control circuit 32, the correspondence to the light source 14c is taken and converted into a height signal of a sludge interface 29. A detecting signal obtained every successive scanning is output to a memory circuit 3 and a comparison circuit 34 and compared with a detecting signal obtained during the scanning before the scanning stared by the memory circuit 33. In the case where the difference is above a predetermined range, an abnormal display is done and also the scanning is carried out again.

摘要： PURPOSE:To confirm whether the detecting result of the light source is a true interface detecting result or not by comparing the transmission amount of the light source detecting a sludge interface with the transmission amount of the light source lighted and scanned after this light source. CONSTITUTION:The light transmission amount of the light source 14c located at a dislocation part 29 between the precipitating parts 25a, 25b becomes large. A signal converted by a photoelectric converting part 15 exceeds the discriminating level of a discriminating circuit 17 and a signal 1 is fed to a controlling circuit 32. The controlling circuit 32 receiving the signal 1 feeds a position signal of the light source 14c corresponding to said signal to a memory circuit 33. The memory circuit 33 maintains the value until the reading signal comes from a reading command circuit 34. Subsequently, the light source after the light source 14c is lighted and when the light from the light source 14d corresponding to a precipitating part 25b is received, the memory contents of the memory circuit 33 is reset. Further, the lighting and scanning are continued, and then, a true precipitating part height at the light source 14b of the interface 26 is detected.
