This invention relates to wastewater treatment plants by a biochemical method.

The purpose of the invention is to increase the efficiency and purification of waste water by pulsing the exposure of the charge and intensively saturating the biofilm with oxygen in the air.

The drawing shows the biofilter.

The device consists of paired containers 1 with loading 2, made for example from scraps of polyethylene pipes and located on the grid 3,

It begins to overflow into the pipeline 10, and then enters the sewer.

The pressure under the cup 6 decreases to atmospheric (the siphon is charged). Water from the tank 1 rushes under the glass 6 and through the outlet 5 flows out of the hydraulic seal 4, filling the bowl 14 mounted on the right arm of the rocker arm 13.

The right-hand rocker arm is lowered and, by means of rigid cable gi 15, provides a revolution in the water distribution

the tank is separated from the bottom of the tank by a certain tilting chute 12, with

distance, hydraulic backplates 4 with outlets 5. Inside the tanks there are siphoning devices, turn the cup 6, mounted on supports 7 and not reaching the bottom of the tank. Two tubes 8 and 9 are attached to the upper part of the glass from opposite sides. One of them is siphonized, ending with an open end above the maximum. 25 levels of water in the tank. 1 and connected to the branch pipe 10 | the other is disconnecting, ends with a cjpt open end at the bottom of the tank. Above the tanks 1 there is a waste water supply pipe 11 and a water distribution device, made in the form of a swinging trench 12. There is a swinging rocker under the tanks. 13 with two bowls 14, located under the outlet nozzles 5 of the hydraulic locks 4. The opposite shoulders of the tilting water distribution trough 12 and the rocker arms 13 are connected by a rigid thrust 15.

The device works as follows.

The wastewater from the feed pipe 11 is directed through the pumping water distribution chute 12, for example, into the right tank 1. The water passes through the bed of charge 2, the surface of which is populated by microorganisms. The organic portion of the contaminants, retained by the biofilm, is subjected to biochemical oxidation using aerobic microorganisms.

As the tank 1 is filled with water under the cup 6, the pressure increases, and the water in the siphon tube 8 is displaced when the maximum level is reached. Order 5511/25

This is done by filling the left tank 1 with water.

Emptying the right tank will stop when the water level in it reaches the level of the lower knee of the connector of the connecting pipe 9. The air entering through this pipe under the cap eliminates the vacuum in it and the siphon is discharged.

The cycle of filling and emptying the containers periodically repeats. Moreover, when containers are emptied, the air is intensively sucked into the bulk of the load and regenerates it.

The biofilter is easy to manufacture and reliable in operation, it allows to intensify biochemical processes. The pulse biofilter FULLY eliminates energy consumption due to self-regulation of wastewater supply.
