摘要： A flocculation monitoring apparatus and a flocculation monitoring method are provided, and the flocculation monitoring apparatus and the flocculation monitoring method are capable of stably measuring a flocculation state of water to be treated even when the number (density) of flocs has increased.
A measurement-light applying part (laser-light applying part 10) applies a measurement light to a measurement region (18) in the water to be treated (8) and a scattered-light receiving part (12) receives a scattered light due to particles of the water to be treated. A measurement value arithmetic part (arithmetic circuit 48) calculates an index related to flocculation of the water to be treated, by using an amplitude of a light reception signal acquired in the scattered-light receiving part.-

摘要： There is provided a coagulation treatment device configured to perform chemical injection control based on a coagulation state monitoring sensor, the coagulation treatment device being capable of accurately controlling the addition amount of a coagulant with the color and amount of particles taken into consideration. A coagulant is added to a coagulation tank 3 by a chemical injection device 4. A detection signal from a coagulation state monitoring sensor 10 provided at a coagulation device 3 is input to a controller 8 and the chemical injection device 4 is controlled. The coagulation state monitoring sensor 10 includes a light emitting unit configured to emit a laser beam toward coagulation treatment solution, and a light receiving unit having a light reception optical axis orthogonal to a light emission optical axis of the light emitting unit. A light reception signal intensity change range is corrected by using light reception signal intensity, and a floc formation state is determined based on a corrected value of the light reception signal intensity change range.

摘要： Provided is a flocculation state monitoring sensor with which blockage of an ejecting part which ejects a gas towards a light emitting part and a light receiving part can be prevented, and which performs stable monitoring. A flocculation state monitoring sensor comprising: a light emitting part 3 which irradiates laser light towards a measuring region S which measures a flocculation state; and a light receiving part 4 which receives light scattered along a direction which intersects with a direction along an optical axis of said light emitting part 3, wherein the light emitting part 3 and the light receiving part 4 are cleaned by air being ejected from nozzles 21, 31 theretowards. A small amount of air is provided to the nozzles 21, 31 between cleaning periods to purge floe, etc.

摘要： A coagulation monitoring device monitoring a treatment state of water to be treated undergoing a coagulation treatment includes a laser light irradiating part irradiating laser light on a measurement region of the water to be treated, the laser light being emitted at at least predetermined time intervals and subjected to an amplitude modulation at a predetermined frequency; a scattered light receiving part receiving scattered light from particles of the water to be treated residing in the measurement region; a signal processing part extracting a measurement value indicative of an intensity of the scattered light, from light-reception signal obtained at the scattered light receiving part; and a measurement value arithmetic part continuously or discontinuously capturing m (m=2 or more) sets of plural measurement values, each set consisting of n (n=2 or more) measurement values, the measurement value arithmetic part extracting a plurality of measurement values in ascending order from a lower value for each set, the measurement value arithmetic part figuring out an average measurement value from a plurality of measurement values with a lowest value removed therefrom. This enables avoidance of influence of flocs generated in water to be treated during coagulation and ensures stable measurement of SS turbidity of water to be treated.
