Abstract
1. Способ непрерывного измерения биохимического потребления кислорода (БПКT), биохимической потребности в кислороде (БПК) и скорости биохимического окисления (k1), отличающийся тем, что процесс отбора воды из водного объекта для анализа БПКT (где Т - длительность биохимического потребления, т.е. инкубационного периода) не общепринятый (т.е. дискретный), а непрерывный, состоящий в том, что организуется непрерывный поток забираемой на анализ воды из водного объекта в трубопровод, причем скорость течения воды в трубопроводе подбирается такая, чтобы за требуемый инкубационный период времени Т вода проходила расстояние между двумя соседними контрольными сечениями трубопровода, в которых установлены датчики для непрерывного измерения концентрации растворенного кислорода в проточной воде. ! 2. Устройство для непрерывного измерения биохимического потребления кислорода (БПКT), биохимической потребности в кислороде (БПК) и скорости биохимического окисления (k1), состоящее из водозаборного модуля и трубопровода с непрозрачными стенками, на котором в определенных сечениях установлены датчики непрерывного измерения концентрации растворенного кислорода, позволяющие вести мониторинг одновременно трех упомянутых показателей качества воды. 1. The method of continuous measurement of biochemical oxygen consumption (BOD), biochemical oxygen demand (BOD) and biochemical oxidation rate (k1), characterized in that the process of selecting water from a water body for BOD analysis (where T is the duration of biochemical consumption, t. i.e., the incubation period) is not generally accepted (i.e., discrete), but continuous, consisting in the fact that a continuous flow of water taken for analysis from a water body into the pipeline is organized, and the flow rate of water in the pipeline is selected such that s for the required incubation period T water passed the distance between two adjacent sections of pipeline control in which sensors are installed for the continuous measurement of dissolved oxygen concentration in the flowing water. ! 2. A device for continuous measurement of biochemical oxygen demand (BOD), biochemical oxygen demand (BOD) and biochemical oxidation rate (k1), consisting of a water intake module and a pipe with opaque walls, on which sensors of continuous measurement of dissolved oxygen concentration are installed in certain sections allowing to monitor simultaneously the three mentioned water quality indicators.
