Реактор периодического действия с интеллектуальной системой управления Fuzzy logic

Номер: RU0000170437U1
Автор: Андрей Дмитриевич Войтенко
Принадлежит: Общество с ограниченной ответственностью "ИВЕА"

Очистка хозяйственно-бытовых и близких к ним по составу производственных сточных вод в подавляющем большинстве случаев осуществляется биологическим методом с применением аэрационных сооружений с активным илом. В условиях резко выраженной неравномерности поступления сточных вод и необходимости запуска установок на минимальных притоках сточных вод наибольшую эффективность имеют установки с реакторами периодического действия, более известными под английским названием sequencing batch reactors (SBR). Процесс биологической обработки осуществляется в одном реакторе, в котором последовательно производится аэрация и затем осветление. Отстаивание ила происходит во время остановки аэрации, а чтобы удалить отстоявшуюся воду, используется устройство для слива. Типичный цикл состоит из пяти последовательных операций, объединенных в три фазы процесса обработки:4. Подача сточной воды и ее биологическая обработка (аэрация/перемешивание в реакторе).5. Отстаивание (отделение ила).6. Опорожнение и затем перерыв (удаление избытка осадка).Длительность циклов определяется длительностью процессов биологической обработки, которые зависят от концентрации сточных вод, поступающих на очистку и от требуемой степени очистки сточных вод.Реакторы периодического действия с интеллектуальной системой управления Fuzzy Logic анализируют в реальном времени данные датчиков рН, ОВП и растворенного кислорода и по внутреннему алгоритму принимают решение о продолжении или прекращении текущей операции биологической обработки. Внутренний алгоритм использует известные зависимости между загрязненностью воды и переменными рН, ОВП и растворенного кислорода. Алгоритм принятия решений включает кластеризацию данных и нечеткую логику Fuzzy Logic. В результате интеллектуального управления максимально используются преимущества реакторов периодического действия и используются дешевые и простые в эксплуатации датчики. Применение реакторов периодического действия с интеллектуальным управлением Fuzzy Logic всегда ...

Wetland Biofilter Chamber with Peripheral Catch Basin and Method of Use Thereof

Номер: US20120091057A1
Автор: Greg B. Kent, Zach J. Kent
Принадлежит: Individual

A horizontal flow water treatment method and wetland biofilter apparatus provides a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

An advanced water treatment method processes a continuous flow of water in a sequence of stages including pre-filtering [] to remove solids, conditioning [] to adjust pH, blending [] with a recycled dense microalgae culture, and passing the resulting mixture through an enclosed, environmentally-controlled photobioreactor [] where nutrients, PCB's, trace metals and other pollutants and regulated compounds are taken up by the algae. The flow from the PBR is separated using cross-flow filtration [] to produce a treated water flow and a dense microalgae flow that is recycled to the blending stage [] upstream. Thus, whereas the algae is recycled, the water entering the system is treated by flowing sequentially through the stages of the system, without any recycling or repetition of treatment stages. 1. A method for advanced water treatment , the method comprising:a) receiving a continuous flow of water;b) pre-filtering the received flow of water to reduce suspended solids;c) conditioning the pre-filtered flow of water to increase bio-availability of nutrient constituents in the pre-filtered flow;d) blending in a blending vessel the conditioned flow with a dense live microalgae flow (RAA) to produce a mixture flow;e) passing the mixture flow once through an enclosed tube photobioreactor (PBR) so that microalgae in the mixture flow reproduce and take up nutrients and trace metals in the mixture flow;f) continuously separating microalgae from the mixture flow exiting the photobioreactor to produce a treated flow (permeate) and the dense live microalgae flow (RAA);g) continuously returning the dense live microalgae flow (RAA) to the blending vessel; andh) measuring a flow velocity of the mixture flow and automatically adjusting the mixture flow to maintain stable mixture levels in the blending vessel and filter equalization tank.2.

The invention relates to an apparatus, methods and applications to grow microorganisms on-site to treat contaminated environments. Furthermore, the invention refers to an apparatus that is designed to function under a wide range of environmental conditions including extreme cold, extreme heat and direct exposure to sunlight. Such environments normally reduce the shelf-life of the organisms in the holding chamber that feeds the fermenter where they are being grown. These environments can also lower the growth rate of the organisms in the fermenter causing diminished cell output. Quite often the optimum point of application for the organisms is outdoor and too far from structures with appropriate protection from ultraviolet radiation from the sun or from excessive cold or hot weather. The invention also claims a dark coating that blocks ultraviolet radiation and a special coating that reflects heat away from the bioreactor. In addition, the invention claims a flexible micropore diffuser that allows aeration while gently mixing the fermentation broth.
