Abstract

Дл этого процесс провод т при переменной скорости фильтровани , меньшей скорости мгновенного проскока, уменьша ее по мере отработки сорбционной емкости в соответствии с данными контрол за концентрацией примесей на выходе из фильтра.The invention relates to wastewater treatment by filtration, in particular, sorption treatment. The method allows to increase the filter performance at a fixed dynamic exchange capacity of the sorbent. For this, the process is carried out at a variable filtration rate, lower than the speed of an instantaneous breakthrough, reducing it as the sorption capacity is developed in accordance with the monitoring data for the impurity concentration at the filter output.
Description
Изобретение относитс к очистке сточных вод фильтрованием, в частности к сорбционной очистке.The invention relates to the treatment of wastewater by filtration, in particular to sorption treatment.
Цель изобретени - увеличение производительности фильтра при фиксировании динамической обменной емкости сорбента.The purpose of the invention is to increase the filter performance while fixing the dynamic exchange capacity of the sorbent.
Способ осуществл ют следующим образом .The method is carried out as follows.
Очистку воды провод т на неподвижном слое сорбента фиксированной динамической емкости, измер на вы- ходе из фильтра концентрацию удал емых примесей, допустимое (проско- ковое) значение которой ограничено и зависит от свойств взаимодействующих и получаемых при очистке веществ .Water purification is carried out on a fixed bed of a sorbent of a fixed dynamic capacity, the concentration of removed impurities measured at the outlet of the filter, the permissible (leakage) value of which is limited and depends on the properties of the interacting and obtained substances.
Определ ют скорость мгновенного проскока удал емых примесей через слой сорбента и процесс очистки провод т при переменной скорости фильтровани , выбира в качестве начальной скорость, меньшую скорости мгновенного проскока, но большую, чем рекомендуетс дл конкретного сорбента при работе с посто нной скоростью фильтровани . Дальнейший процесс очистки воды ведут до по влени на выходе сло сорбента проскоковой концентрации удал емых примесей с переменной скоростью, наблюда за тем, чтобы величина концентрации не превышала значение проскоковой.The speed of the instantaneous breakthrough of the removed impurities through the sorbent layer is determined and the cleaning process is carried out at a variable filtration rate, choosing an initial speed lower than the speed of the instantaneous breakthrough, but greater than recommended for a particular sorbent when operating at a constant filtration rate. A further process of water purification is carried out until the emergence of a layer of sorbent concentration of the removed impurities at a variable rate at the exit of the sorbent layer, watching that the concentration does not exceed the value of the slip.
Таким образом, при проведении процесса с увеличенной скоростью фильтровани повышаетс производительность фильтра и поддержание скорости переменной, но не превышающей значение , при котором происходит выход проскоковой концентрации примесей, способствует одновременно сохранению неизменной динамической обменной емкости сорбента.Thus, when carrying out the process with an increased filtration rate, the filter performance and maintenance of the speed variable, but not exceeding the value at which the leakage concentration of impurities occurs, contributes simultaneously to maintaining the constant dynamic exchange capacity of the sorbent.
