Description

The proposed utility model relates to sanitary engineering and can be used in the treatment of domestic wastewater of separately located facilities, small towns and individual residential buildings.

A known bioreactor containing fermentation and separation chambers, a partition with holes, inlet and outlet pipelines (see Randolph R. What to do with wastewater. M. "Stroyizdat", 1987, p. 44).

The well-known bioreactor is a simple and easy-to-use device for water purification, but a number of its structural features allow us to indicate the following disadvantages:

1. Large construction volume, since the bioreactor includes a separation chamber, which makes up 30% of its volume, in which the processes of decomposition of organic pollutants practically do not take place, since the concentration of silt in it is negligible. In the decomposition chamber, mainly only the physical purification of water by gravitational sedimentation of suspended solids occurs. In connection with this, the volume of the fermentation chamber remains significant and, together with the separation chamber, is large.

2. The low fermentation rate is the reason for the large construction volume, since the contact of silt with water is insignificant, since its fermentation occurs only in the lower part of the bioreactor - in the sediment accumulator. The mixing of water with gases released during the decomposition of organic substances is not able to significantly intensify the cleaning process: low technological reliability indicators, since with a significant salvo flow, which is typical for individual house drainage systems, not only dissolved organic substances can slip through the bioreactor, but suspend.

Known bioreactor containing fermentation and separation chamber, inlet and outlet pipelines (see USSR author's certificate No. 1754675, M. Cl. C02F 3/28, publ. 1992).

The disadvantage of this bioreactor is the low degree of purification.

Known bioreactor containing a housing with a lid and a hatch, separated by vertical partitions with overflow openings on the camera, the inlet and outlet for the treated waste fluid, the housing is made in the form of a glass in which the vertical partitions are installed radially and form sector cameras of equal volume in the direction of fluid movement - inlet, overflow and outlet, overflow openings are made in the form of vertical slots located on the periphery of the partitions near the walls of the housing, the width of the slots in the towns decreases in the direction of fluid movement, and the height does not exceed the height of the outlet (see Patent RU No. 2055816, M. Cl .. C02F 3/28, publ. 1996).

The disadvantage of this bioreactor is the low degree of purification.

A bioreactor is known, which is a container without a bottom, closed by a lid, and mounted in a separate container, the internal cavity of which is connected to the inlet, outlet and evacuation pipes, inside the container there are cells with aerobic microorganisms living on them, an airlift running through the center of the container, working from the air supply source, a return air outlet pipe is installed on the cover (see http://kakpravilnosdelat.ru/septik-fast/).

The disadvantage of this bioreactor is the low degree of purification.

A bioreactor is known, which is a container without a bottom, closed by a lid, and mounted in a separate container, the internal cavity of which is connected to the inlet, outlet and evacuation pipes, inside the container there are cells with aerobic microorganisms living on them, an airlift running through the center of the container, working from the air supply source, a return air outlet pipe is installed on the cover (see http://oseptike.ru/septik-fast).

The disadvantage of this bioreactor is the low degree of purification.

The technical result of the proposed utility model is to increase the degree of purification by involving all wastewater in the tank, ensuring an increase in the path of movement of water contaminated with elements of organic origin or chemicals, with air, involving all sewage in the purification process, due to the created flow elimination of stagnant zones in the bioreactor.

The technical result is achieved by the fact that in the bioreactor, which is a container without a bottom, closed by a lid, and mounted in a separate container, the inner cavity of which is connected to the inlet, outlet and evacuation pipes, cells with aerobic microorganisms living on them are located inside the container, an airlift running from the air supply source passes through the center of the container, a return air pipe is installed on the lid, a pipe for collecting water contaminated with elements of organic origin or chemicals, in the airlift is located away from the honeycomb, near the inner wall of a separate container, and below the honeycomb, and the airlift air supply pipe is mounted in the air and liquid passage pipe in the form of a discharge in the direction of liquid and gas flow.

In FIG. 1 schematically shows the proposed bioreactor, consisting of a container 1 without a bottom with cells located inside 2 with aerobic microorganisms living on them; airlift 3 passing through the center of the container 1; air blower 4, which can be used as either a fan or a compressor; pipes 5 return air outlet (ventilation pipe) mounted on the lid 6, covering the container 1; a separate container 7, in which a container 1 with cells 2 is mounted, pipes 8 for pumping; inlet pipe 9, outlet pipe 10; pipes 11 for supplying air to the airlift 3, pipes 12 for the passage of air and liquid. Position 13 denotes a precipitate.

In FIG. 2 schematically shows the connection of pipes 11 and 12.

The bioreactor is a container 1 without a bottom, closed by a lid 6, and mounted in a separate tank 7. The internal cavity of the tank 7 is connected to the input 9, output 10 pipes. The bioreactor also includes a pipe 11 for supplying air to the airlift 3 pipe 12 for the passage of air and liquid. Inside the container 1, honeycombs 2 are located with aerobic microorganisms living on them. Through the center of the container 1 passes an airlift 3, working from an air supply 4. On the lid 6, a pipe 5 for returning air is installed. The pipe 12 for the intake of water contaminated with elements of organic origin or chemicals in the airlift 3 is located away from the honeycomb 2, near the inner wall of a separate container 7, and below the honeycomb 2. The air 11 air supply pipe 11 is mounted in the air and liquid passage pipe 12 in the form of a branch in the direction of flow of liquid and gas.

The intake of water contaminated with elements of organic origin or chemicals, in the airlift is carried out at the wall of a separate tank 7 below the cells 2. This provides an increase in the path of movement of water contaminated with elements of organic origin or chemicals, with air coming from the supercharger 4.

The operation of the device is based on the method of biological aerobic purification of waste fluid. He suggests that water contaminated with organic elements or chemicals is purified by a colony of bacteria that have been specially bred and placed in cells 2. For bacteria living in cells, it is vital that any liquid waste, as well as oxygen, is continuously supplied. Organisms living in the colony break down and fully absorb all incoming organic and chemical substances. The waste products of the bacteria described are carbon dioxide and industrial water, the purity of which is 98%.

A high degree of purification due to the involvement of all effluents in the tank in the purification process, ensuring an increase in the path of movement of water contaminated with elements of organic origin or chemicals, with air is the advantage and advantage of the proposed technical solution compared to the prototype.
