Description

•Изобретение относится к биохимической очистке сточных вод, а именно к биологическим фильтрам с искусственной аэрацией.• The invention relates to biochemical wastewater treatment, namely to biological filters with artificial aeration.

Известен биофильтр, содержащий корпус с решетчатым дном, на котором размещена загрузка, узел подачи, распределения ц отвода обрабатываемой воды, трубопровод подвода воздуха .Known biofilter containing a housing with a trellised bottom, on which is placed the load, the supply unit, the distribution of distribution of the outlet of the treated water, the air supply pipe.

с перфорированными патрубками, расположенными в загрузке (1) .with perforated nozzles located in the load (1).

Однако известный биофильтр не обеспечивает равномерную подачу воздуха по всему объему. В створе наклонных трубок не вся плоскость обеспечивается равномерной подачей воздуха, особенно верхних слоев, в наибольшей степени подверженной заиливанию. К тому же конструкция известного аэрофильтра усложнена.However, the known biofilter does not provide a uniform supply of air throughout the volume. In the alignment of inclined tubes, not the entire plane is provided with a uniform supply of air, especially the upper layers, which are most susceptible to siltation. In addition, the design of the known air filter is complicated.

В известном устройстве в процессе эксплуатации не имеется возможности замены перфорированных трубок без выгрузки-загрузки биофильтра. Преиму- __ щёства установки перфорированных тру- “ бок в загрузке не могут быть использованы на существующих биофильтрах без выгрузки-эагруэки.In the known device during operation it is not possible to replace perforated tubes without unloading and loading the biofilter. The advantages __ of the installation of perforated tubes in the load cannot be used on existing biofilters without unloading-eagrueki.

Цель изобретения - повышение эффективности использования биофильтра 30 путем обеспечения равномерной подачи воздуха по всему объему загрузки и облегчение эксплуатации.The purpose of the invention is to increase the efficiency of use of the biofilter 30 by ensuring a uniform air supply throughout the volume of the load and ease of operation.

Для достижения поставленной цели узел.подачи воздуха размещен' над загрузкой и установлены перфорированные трубки, имеющие снизу конус со спиралеобразным резцом, перпендикулярно дырчатому дну.To achieve this goal, the air supply unit is placed above the loading and perforated tubes are installed, having a cone with a spiral-shaped cutter at the bottom, perpendicular to the hole bottom.

Для искусственной вентиляции биофильтра прйменено усложненное междудонное пространство с гидрозатвором. _k For artificial ventilation of the biofilter, a complicated double bottom space with a water seal is used. _k

На чертеже изображен биофильтр,общий вид.The drawing shows a biofilter, General view.

Биофильтр содержит корпус 1,загрузку 2, водораспределительное устройство 3, узёл 4 подачи воздуха,перфорированные трубки 5, которые снизу имеют конус 6 со спиралеобразным резцом 7 и которые установлены перпендикулярно к дырчатому дну 8, сплошное днище 9 с лотками-10.The biofilter contains a housing 1, a load 2, a water distribution device 3, an air supply unit 4, perforated tubes 5, which bottom have a cone 6 with a spiral-shaped cutter 7 and which are installed perpendicular to the hole bottom 8, a solid bottom 9 with trays-10.

Биофильтр работает следующим образом.The biofilter works as follows.

Загрязненная вода подается водораспределительным устройством 3,проходит через загрузку 2. По перфорированным трубкам 5, .подсоединенным к узлу 4 подачи воздуха, в загрузку поступает воздух. Очищенная сточная во893893 да отводится из биофильтра по лоткамContaminated water is supplied by the water distribution device 3, passes through the load 2. Through the perforated tubes 5 connected to the air supply unit 4, air enters the load. Purified waste water 893893 and is discharged from the biofilter in trays

10, выполненным в сплошном днище 9.10, made in a solid bottom 9.

Установка вертикальных перфорированных трубок с конусами обеспечивает равномерную подачу воздуха во всем объеме загрузки, упрощает введение их в загрузку на существующих сооружениях биофильтрацйи, монтаж и демонтаж во время эксплуатации.The installation of vertical perforated tubes with cones ensures a uniform air supply throughout the volume of loading, simplifies their introduction into loading at existing biofiltration facilities, installation and dismantling during operation.

Claims

The invention relates to biochemical wastewater treatment, in particular to biological filters with art aeration. A biofilter is known, comprising a housing with a lattice bottom, on which the load is located, a feed unit, distribution and, removal of treated water, an air supply pipeline with perforated tubes located in the load tl3 However, the known biofilter does not even uniformly supply air throughout . In line with inclined tubes, not all planes provide with a uniform supply of air, especially the upper layers, which are most susceptible to silting. In addition, the construction of a well-known aerofilter is complicated. In the known device during operation there is no possibility of replacing perforated tubes without unloading and loading the biofilter. Advantages of installing perforated pipes in the load can not be used on existing biofilters without unloading and loading. The purpose of the invention is to increase the efficiency of the use of a biofilter by ensuring uniform air supply throughout the load volume and facilitating operation. In order to achieve this goal, the air supply hub is placed by loading and perforated tubes are installed, having a cone with a spiral cutter from below, perpendicular to the perforated bottom. For artificial ventilation of the biofilter, a complicated double bottom space with a water seal is applied. j The drawing shows the biofilter, a general view. The biofilter includes a housing 1, a load 2, a water distribution device 3, an air supply unit 4, perforated tubes 5 that have a cone 6 with a spiral cutter 7 and that are installed perpendicular to the perforated bottom 8, a solid bottom 9 with trays-10. The biofilter works as follows. The contaminated water is supplied by the water distribution device 3, will flow through the load.

2. The perforated tubes 5, which are connected to the air supply unit 4, receive air in the charge. Purified wastewater is discharged from the biofilter through trays 10 made in a solid bottom 9. Installing vertical perforated tubes with cones ensures uniform air flow throughout the loading volume, simplifies their insertion into the loading on existing biofi.practice facilities, installation and removal during operation. Claims of the Invention Biofilter, -containing casing with grated bottom, on which is placed the loading, supply, distribution and drainage unit of the treated water, air supply pipe with perforated nozzles located in the loading, characterized in that, in order to increase the efficiency of use uniform air supply throughout the load and ease of operation, it is equipped with cones with spiral-shaped cutters attached to the ends of perforated pipes, and perforated the pipes are installed perpendicular to the bottom of the case, and the air supply pipe is located above the load.
