A disadvantage of the known BOXING pond is that it does not work in winter conditions, when the cleaning process is carried out under anaerobic conditions.

The purpose of the invention is the provision of wastewater treatment in anaerobic conditions.

The objective is achieved by the fact that the water layers filled with sand, gravel, sand planted with aquatic vegetation and is connected with the tank, equipped with a level switch and pump Assembly.

Biological oxidant stable contact /BOXING/ ponds, designed to work both growing and growing seasons and based on biological wastewater treatment in anaerobic conditions.

BOXING ponds contain capacity, layers filled with sand 2 gravel 3 sand 4 planted with aquatic vegetation 5, connected by pipes 6 and 7 are equipped with valves 8 and 9 with the electric motors 10 and 11, with the tank 12, provided with a level switch 13 and the pump 14 and motor 15, the motor 16 and the suction pipe 17, with the tank 18 having a relay urovnya electric motor 23, connected to the level switch 19. The motors 10 and 11 are connected to the motor control 24 that has a software device 25. The control system of the electric motor 16 is connected to a level switch 13.

BOXING ponds are as follows.

The initial population of the sewage six tanks are made for manual control of the valves 8 and 9 with the electric motors 10 and 11. After that, the control valves 8 and 9 with the electric motors 10 and 11 are transferred to the auto mode.

At the beginning of the seventh day software device 25 closes the circuit of the motor control 24, including the electric motors 10 and 11, opening the valve 9 in the first tank and the valve 8 in the seventh capacity. When open the valve 9 decontaminated waste water from the first tank 1 through the pipe 7 flows into the reservoir 18.

During filling of the tank 18 level switch 19 closes the circuit of the control motor 23, including the motor 22 and the pump 21 pumps the liquid waste into the irrigation network. After emptying the first tank 1 level of waste water in the tank 18 is reduced and the level switch 19 opens circuit control motor 23, while electr electric motor 16, including the electric motor 15, and the pump 14 pumps contaminated waste water from the tank 12 in the seventh container 1 during the day. At the beginning of the eighth day, a programming device 25 closes the circuit of the motor control 24, including the electric motors 10 and 11 and opening the valve 8 in the first and the valve 9 in the second tank and closing the valve 9 in the first and the valve 8 in the seventh tanks. Decontaminated waste water from the second tank 1 flows into the reservoir 18, and contaminated waste water during the day is pumped into the first tank 1 from the tank 12.

This process is periodically repeated. Using the proposed BOXING ponds is achieved wastewater treatment in anaerobic conditions, which will reduce the square BOXING ponds and to provide year-round cleaning.
