A method for control of quality of purification of sewage waters in which two coherent light beams are directed at angle one to another to probing zone of solution, with registration with photo-receiver of intensity of light radiation dissipated by particle, with determination of the period and the number of Doppler signals in unit time. First solution prior to purification is directed to measuring cell, with measurement of the period and number of pulses of Doppler signal in unit time, after that solution after purification is directed to the measuring cell, with measurement of the period and the number of pulses of Doppler signal in unit time as well, with calculation of the velocity and concentration of particles, and with evaluation of quality of purification through determination of the ratio of concentration of particles prior to purification to concentration of particles of solution after purification. |
