METHOD FOR INTERPOLATION CONTROL OF WASTE WATER AND INDUSTRIAL WASTES POLLUTION Russian patent published in 2019 - IPC G01N33/18 C02F1/00 

FIELD: ecology.

SUBSTANCE: invention relates to methods of monitoring the environment and can be used to control contamination of sewage water or surface water of natural water bodies. Method of interpolation control of contamination of waste water and industrial effluents involves measurement of concentration of contamination in sewage pipe at inlet and outlet of controlled section and comparison of measurement result with maximum permissible value of MAC. Measurement of concentration of contamination and comparison of measurement result with maximum permissible value of MAC is carried out using posts analyzing contamination of waste water or industrial wastes, installed at inlet and outlet of sewage pipe, made in the form of measuring modules connected through switchboard to computer unit. Additionally determining probability of detecting P_DET. contamination in the absence of its fixation by said analysis stations, representing a sequence of measurements as a stationary Poisson flow, calculating probability P_DET. by formula:

where λ is average amount of occurrence of contamination of certain type per unit time; T₀ – time of waste water flow from the beginning of observations to the analysis post installed at the sewer pipe inlet; T₁ is the time required to obtain information on the type and degree of contamination from the analysis post installed at the inlet of the sewage pipe; T₂ is the waste water flow time along the sewage pipe; T₃ is the time required to obtain information on the type and degree of contamination from the analysis post installed at the outlet of the sewage pipe.

EFFECT: invention provides higher reliability of pollution control of waste water in natural-industrial territorial complexes.
