Изобретение относитс к устройствам , предназначенным дл обработки сточных вод путем биохимического окислени .This invention relates to devices for treating wastewater by biochemical oxidation.

Известен биофильтр, содержащий установленньй на горизонтальном валу в резервуаре пакет дисков с карман ами,1 J.Known biofilter containing installed on the horizontal shaft in the reservoir package of disks with pockets, 1 J.

Однако известное устройство неэффективно а работе, так как насыщение воды кислородом происходит периодически и только на смоченных поверхност х дисков.However, the known device is inefficient in operation, since the water is saturated with oxygen periodically and only on wetted surfaces of the disks.

Цель изобретени - повьшение эффективности использовани за счет обеспечени непрерывной аэрации и орошени дисков.The purpose of the invention is to increase the efficiency of use by providing continuous aeration and irrigation of the discs.

Указанна цель достигаетс тем, что в погружном биофильтре, содержащем резервуар в виде полуцилиндра , с протекающей в нем сточной водой , в которую погружены пакеты дисков, насаженных на горизонтальную ось, в диски вмонтированы расположенные по их окружности и вдоль их оси горизонтальные отрезки закрытых с торцов труб, которые имеют отверсти , наход щиес снизу труб в момент их погружени в сточную воду.This goal is achieved by the fact that in a submersible biofilter containing a semi-cylinder reservoir, with waste water flowing in it, in which packages of disks mounted on a horizontal axis are immersed, horizontal segments of the ends closed along their circumference are embedded in the disks pipes that have holes that are below the pipes when they are immersed in wastewater.

На 4мг. 1 показан биофильтра продольный горизонтальный разрез; на ,фиг. 2- поперечный разрез А-А на фиг.1.At 4mg. 1 shows a biofilter longitudinal horizontal section; in FIG. 2 is a cross-section A-A in FIG.

Биофильтр включает в себ резервуар 1 в виде полуцилиндра, заполн емый сточной водой, в которую полупогружёны пакеты дисков 2, насаженных на горизонтальный вал 3, а в диски по их окружности вмонтиро15 ваны горизонтальные отрезки труб 4, имеющие по образующей отверсти 5 и заглушки 6 в торцах.The biofilter includes reservoir 1 in the form of a semicylinder filled with waste water, into which packages of disks 2, mounted on a horizontal shaft 3, are semi-loaded, and horizontal sections of pipes 4, forming an opening 5 and plugs 6 the ends.

Погружной биофильтр работает следующим образом. Submersible biofilter works as follows.

Claims

The waste water, flowing along tank 1, fills the space between the disks 2 rotating on the horizontal shaft 3. The biological film formed on the surface of the disks 2 absorbs organic substances in the waste water, oxidizes them and uses them as a source of nutrition and energy, thus purifying waste water from organic impurities with their transformation into mineral substances, partly remaining in the water, and partly released into the atmosphere. A biological film, as is known, consists of aerobic microorganisms and in order to activate their vital activity, as a result of which water purification is achieved, a continuous supply of microorganisms with nutrients and air oxygen is required. This is achieved by the fact that the horizontal sections of pipes built into packages Pdiskov 2 at the moment of their immersion in waste water have openings 5 facing downwards and are therefore filled with air, the latter being displaced by water as the discs rotate and the tubes rotate around the horizontal axis. The air displaced from the pipes rises through. a layer of water saturates it and the streamlined biofilm with atmospheric oxygen, thus providing a continuous supply of microorganisms of the biofilm in the water volume with oxygen. When leaving the water pipe 4 have holes 5 facing up and filled with water. In the further rotation, the holes of the 5 pipes, turning around the horizontal axis, both bake the emptying of the pipes. The exuding water not only irrigates the biofilm, giving it nourishment, but also becomes saturated with oxygen in the air, increasing the total aeration of the waste water. Thus, the aerobic microorganisms of the biological film, freely floating in the entire volume of the waste water, have a continuous supply of food and oxygen to the air, which ensures the growth of biomass, activates its viability and, as a result, increases the oxidative power, and hence the cleaning ability of the device. Compared with the known devices in the proposed submersible biofilter, the oxidizing power is increased due to: a) the creation of an uninterrupted supply of air oxygen to the biofilm; b) creating a continuous supply of organic matter wastewater to the biofilm; c) the simultaneous supply of oxygen and organic wastewater to the biofilm; d) activation of aeration of the total volume of waste water; e) intensification of diffusion flows of oxygen dissolved in wastewater in the direction of the biofilm. Claims of the invention A submersible biofilter containing a package of disks with pockets mounted on a horizontal shaft in a tank, characterized in that, in order to increase the efficiency of use by providing continuous aeration and irrigation of the disks, the pockets are made of end pipes closed with a generatrix mounted into in the disks on their periphery.
