Description
Изобретение относитс к очистке сточных и природных вод, а белее . конкретно к способам автоматического контрол растворимости газа в этих водах при их биохимической очистке и может быть использовано в водоподготовке .The invention relates to the treatment of waste and natural waters, and whiter. specifically, to methods for automatically controlling the solubility of gas in these waters during their biochemical purification and can be used in water treatment.
Известен способ контрол растворимости газа в воде при ее биохимической очистке путем измерени парциального давлени этого газа 1.A method is known for controlling the solubility of a gas in water during its biochemical purification by measuring the partial pressure of this gas 1.
Недостатком такого способа вл етс невозможность пр мого определени растворимости газа из-за независимости его парциального давлени от физико-химического состава сточных и природных вод.The disadvantage of this method is the impossibility of directly determining the solubility of a gas due to the independence of its partial pressure from the physico-chemical composition of waste and natural waters.
Известен также способ автоматического контрол растворимости в воде при биохимической очистке путем измерени активности газа 2.There is also known a method for automatically controlling the solubility in water during biochemical purification by measuring the activity of a gas 2.
Недостатками известного способа вл ютс невысокие точность (не бо лее +15-20%) -и надежность процесса контрол (по наработке на отказ не более 1000 ч при доверительной веро тности 0,8) из-за вли и на этот процесс растворенных солеёй, активного ила, органических веществ и температуры .The disadvantages of this method are low accuracy (no more than + 15-20%) - and the reliability of the monitoring process (with a time to failure of not more than 1000 hours with a confidence probability of 0.8) due to the influence of dissolved salt on this process, activated sludge, organic matter and temperature.
Целью изобретени вл етс оптимизаци процесса контрол растворимости газа в воде.The aim of the invention is to optimize the process of controlling the solubility of a gas in water.
Указанна цель достигаетс тем, что измер ют концентрацию газа в воде и по отношению газа в воде к , This goal is achieved by measuring the concentration of gas in water and the ratio of gas in water to
10 его активности определ ют растворимость газа.10 its activities determine the solubility of the gas.
На чертеже представлена схема осуществлени способа.The drawing shows the implementation of the method.
Сущность способа состоит в следу15 ющем.The essence of the method is as follows.
В анализируемую сточную или природную воду, обрабатываемую в очистном сооружении 1, помещают датчик 2 активности растворенного газа, напри20 мер кислорода или хлора, и датчик 3 концентрации этого газа. Датчики 2 и 3 св заны между собой через блок 4 согласовани , подключенный к регистрирующему прибору 5.Sensor 2 of the activity of the dissolved gas, for example, oxygen or chlorine, and sensor 3 of the concentration of this gas are placed in the analyzed waste or natural water treated in the sewage treatment plant 1. Sensors 2 and 3 are interconnected via matching unit 4 connected to recording instrument 5.
2525
Выходные сигналы датчиков 2 и 3, пропорциональные соответственно активности газа и его концентрации в воде, поступают на вход блока 4. В блоке 4 фо млируетс выходной сигнал, The output signals of sensors 2 and 3, proportional to the activity of the gas and its concentration in water, respectively, are fed to the input of block 4. In block 4, the output signal is generated,
30 пропорциональный отношению концентра30 proportional to the concentration
