After contact with microorganisms, the waste liquid enters the sedative compartment 8 and by means of airlift 13 it is supplied to the upper chamber, from where it is discharged to the lower chamber by means of a siphon 15. The described operation is repeated many times.

This invention relates to the biological purification of domestic waste water and those close to it in terms of the composition of industrial wastewater using attached microorganisms on a filler with a significantly developed surface.

The purpose of the invention is to increase the productivity and oxidizing state of i: -; ocTi, by improving the use of air oxygen.

} 1a of FIG. 1 shows a device for the biological treatment of wastewater in PPA; in fig. 2 upper and lower chambers; and FIG. 3 - the same, in nJiA ie, in FIG. 4 shows section A-A in FIG. H; in fig. 5 is a view B in FIG. 3 for f, 6 is a section BB in FIG. 3.

- The device consists of secd, each of which includes the bottom and top

new chambers 1 and 2, the volume of which is determined by the flow rate of the treated liquid and the required length of 1: -. The lower chamber 1 is a container, which is divided by partitions 3 and is divided into two workers and two sedative compartments 5.6 and 7.8. In the working compartments place containers 9 with a stationary brush gauge. Bulkheads 3 and 4 play the role of a jetting device that allows the treated fluid to compress 1g of contact with the active biome. The working and sedative compartments communicate through the lower slot 10-1 separating them;

The compartments have an overflow edge 11. The second soothing compartment 8 is equipped with a tubular well-well 12 with a bottom for accommodating the airlift 13, which serves to move the fluid from the lower chamber to the upper and one (5 temporary airlift aeration. Adj. compartments 7 and 8 are connected to each other by siphon tubes 14 for emptying.

The upper chamber 2 is similar in structure to the lower one, only the second soothing compartment in the course of the fluid movement is equipped with a siphon 15 for discharging the cleaned fluid into the sedative compartment. 7 bottom camera 1. On the downward branch of the siphon 15 there is an ejector 16 with a suction nozzle for jet aeration of the cleaned
