JpGxaxxK level,

A known installation of biochemical wastewater treatment on a ship containing an aeration tank with an aerator, a sump with a distribution unit and airlift and technological pipelines (UK patent No. 1354126, M. Cl. With 02 With 1/06, 1974).

Signs that are common to the known installation and the claimed technical solution are the presence of an aeration tank, sedimentation tank and distribution unit.

The reason that prevents obtaining in the known installation the required technical result is the unmodular installation.

The prototype is a plant for biochemical wastewater treatment on ships, containing an aeration tank with an aerator, a sump with a distribution unit and airlift and process pipelines, while the distribution unit is made in the form of a degasser pipe with an expander, a reflector visor and additional pipes for removing excess water and foam, and the sump is equipped with an annular chamber mounted on it with openings for collecting water, with branch pipes 2000105046

yes clean water and air at the same time airlift is placed

along the axis of the degasser pipe and connected to the aeration tank (USSR copyright certificate 837933, M, Cl. C 02 F 9/00, 1981).

Prienaki, which is a commonplace of the prototype and the claimed technical solution, are the presence of an aeration tank with an aerator, a sump with a distribution unit and technological pipelines.

The reason that prevents obtaining the required technical result in the prototype is the non-modular implementation of the installation, which complicates the installation of the installation in soums.

The problem to which the invention is directed, is to simplify the installation ionization on ships.

The technical result that mediates the solution of this problem is to perform the installation in the form of transport modules.

The technical result is achieved by the fact that the biological wastewater treatment plant is made in the form of two spatially and hydraulically mating containers and contains a first aeration tank and a sump installed in the first container and a mineralizer and a second aeration tank installed in the second container, the input of which is made with the possibility of hydraulic connection with the water outlet sedimentation tank, and the outlet - with the ability to connect to the outlet pipe of the installation through the disinfection unit or

without it, in the case of water disinfection inside the aeration tank, the inlet of the first aeration tank is made with the possibility of hydraulic connection with the sewage supply pipe for cleaning, and the outlet is directly connected to the inlet of the sump, the sludge outlet is made with the possibility of connection through the sludge divider with the inlet of the return aeration tank of the first aeration tank and mineralizer inlet.

New in relation to the prototype features of the claimed technical solution consist in the installation in the form of two spatially and hydraulically mating containers, in the presence of a second aeration tank and a mineralizer, and also in the fact that the first container and a sump are installed in the first container, and the mineralizer and the second are installed in the second container aeration tank

The installation is made in the form of two containers 1 and 2, which are made with the possibility of spatial and hydraulic interfacing with each other. In the first container 1, the first aeration tank 3 is installed, equipped with an aerator 4 and a partition 5, as well as a settler b. At the same time, the partition 5 does not reach the bottom of the aeration tank 3, thereby dividing the very last into two sections ™ Za and 36. Section Za is the first in the direction of movement of the water and is connected to the inlet pipe 7 for supplying the waste ORGAN for cleaning. Section 36 is the second along the course of the movement of water and is connected through the Sv tray to the entrance of the settler b. In the second container 2, a mineralizer 8 and a second aeration tank 9 are installed, which performs the function of a post-aeration stage. The inlet of the second aeration tank 9 is connected to the outlet of the water of the sump b by means of a pipeline 10. The outlet 11 of the sludge of the sump b is connected to the input of the sludge divider 12, one output of which is connected to the input 13 of the return sludge of the first aeration tank 3, and the second output to the input 14 of the mineralizer 8. The output of the second aeration tank 9 is connected to the input of the bactericidal block 15, the output of which is connected to the output pipe 16 of the installation. In addition, the mineralizer 8 and the second aeration tank 9 are equipped with corresponding aerators 4,

The hydraulic connections between the installation devices described above are presented for the case when the installation is assembled on the ship. When the installation is not yet assembled, hydraulic connections between devices located in different containers are only potentially possible. Moreover, the scope of patent claims is determined not by the actual connection between devices located in different containers, but by the potential possibility of these connections. Hence, the corresponding features are formulated as follows: the inlet of the second aeration tank 9 is made with the possibility of hydraulic connection with the outlet of the water of the sump 6; the outlet 11 of the sludge settler b is configured to be connected through a sludge divider 12 with the inlet 13 of the return sludge of the first aeration tank 3 and the inlet 14 of the mineralizer 8; second aeration tank exit

9 is made with the possibility of hydraulic connection

with the output pipe 16 of the installation through the block 15 disinfection of purified water.

Installation is as follows.

Previously, a hole is cut out on board the vessel (whether it is left or right) in the size of container I, 2. Then, through this hole, with the help of lifting mechanisms, one container is brought into the vessel first, and then the other. After that, the containers are installed in a predetermined position, the devices located in the containers are fixed and connected using the corresponding process pipelines. They also install external devices (pumps, an equal flow column, flow meter, bactericidal unit, compressor, silencer, etc.), which are connected to devices located in containers in an appropriate way. After that, the hole in the side of the vessel is brewed.

The operation of the installation in assembled form is as follows.

Contaminated wastewater from a sump through an equal flow column (a sump and a column are not shown) through a pipeline 7 enters the section For the first aeration tank 3. In the section For water, it flows by gravity downward, passes under the partition 5 (which does not reach the bottom of the aeration tank 3), enters section 36, in which it moves up. Inside azrotenka 3 installed cassettes for attaching microflora (not shown). A corresponding aerator 4 is installed under the partition 5 to ensure air supply to both sections of the aeration tank 3. Biologically purified water from the aeration tank 3 enters the sump 6 through the tray 3. In the sump 6, suspended solids are separated from the purified water.

The settled water from the sump 6 through the pipeline 10 is discharged into the second aeration tank 9 (post-aeration stage). In the lower part of the aeration tank 9 there is a corresponding aerator 4 for supplying air. Purified water from the aeration tank 9 is pumped (not shown) to a bactericidal unit 15 with ultraviolet radiation, disinfected, and then discharged overboard 16 into the water pipe (into the reservoir). In this case, it is possible to use water chlorination in AeroFenka 9 instead of using a separate bactericidal unit 15.

Returnable sludge from the sump 6 by means of airlift (not shown) enters the sludge divider 12. In operating mode, the return sludge enters the first section for the aeration tank 3. Once a week (specified by trial operation), excess activated sludge is discharged into the mineralizer 8, while the mineralizer 8 is also equipped with an appropriate aerator 4, which provides air purge. This purge is necessary for the effective mineralization of sludge, which is accumulated in the mineralizer 8 and periodically (once in navigation) is taken out together with solid waste.
