Description

(5A) DEVICE FOR CLEANING OF WASTE

I

The invention relates to the field of domestic wastewater treatment, to combined facilities using aeration and settling processes.

The aeration tank is known, which contains a cylindrical tank divided by a cylindrical partition into aeration and settling zones. In the annular zone - the aeration chamber, mesh nozzles with a compressed air supply system are installed.

A disadvantage of the known device is the need to use high-pressure blowers and high power consumption.

The purpose of the invention is to increase the efficiency of use by reducing capital and operating costs.

This goal is achieved by the fact that in a device comprising a cylindrical body divided by a coaxiVOD

The cylindrical partition located on the aeration chambers with the nozzle and settling, the source, fluid and air input units and the drain pipe, the nozzle is designed as a spiral tray with perforated tubes located in the aeration chamber along its entire height. In addition, in the lower part of the cylindrical partition holes are made

to arch type.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one. ,

The device comprises a cylindrical housing 1, located, for example, in the central part of a high-rise building, a pipe 2 for introducing source water, chambers are located in the center of the housing, and a settling tank 3 is for settling and / m.

20 In the annular space between the wall of the housing and the partition there is an aeration chamber in which the spiral 392 is installed along its entire height.

Trays mounted under the minimum1 1 ANGLE (slope), on the tray are plastic perforated tubes 5- In the lower part of the cylindrical partition there are 6 holes of an arched shape. In the sump 3, a silt pipe 7 is installed, and in the upper part of the device, a drain pipe 8, a cover 9 and a pipe 10 for exhausting the gas-air mixture, air is supplied to the device through pipe 1 1.

The device works as follows.

Sewage water through pipe 2 is fed to the first turn of the spiral tray. Recycled activated sludge is fed simultaneously from the power pipe 7 to the first turn. Formed with a mixture is aerated by air through perforated tubes 5. Discharge through the tray k the mixture enters through the holes 6 into the settling tank 3. the water through pipe 8 is drained from the device.

The advantage of the proposed device is ECONOMY. I use the space, since the vertical position of the device in the building is much more efficient than the location in the basement, reducing energy costs, favorable temperature conditions for cleaning processes.
