Description

The invention relates to the treatment and treatment of wastewater.

A biological oxidation contact stabilization pond (BOX pond) is known in which, in order to ensure deworming of the effluent during discharge and size reduction of the devices by reducing sediment agitation and ensuring vertical movement of the water intake device, the water distribution device elastic cylinder with clamping collars and spacer rings having connecting pipes and vertical rods, and kzhe floats, placed at the periphery of the upper water intake openings.

However, the intake device does not provide wastewater treatment from microalgae, which fall into open water bodies and cause them to bloom. In addition, the intake device loses mobility due to corrosion of vertical rods that are constantly in the waste water.

The purpose of the invention is to increase the degree of purification due to the removal of microalgae from sewage when discharging them into watercourses, increasing reliability, reducing metal intensity and simplifying the design of the intake device.

The goal is achieved by those. that in the BOX pond containing water bodies with inclined bottoms, the pipelines for the supply and disposal of wastewater with water intake devices, the latter is installed in addition

holding tank communicated with ponds on a frame mounted on a building piping pivotally mounted on a water outlet and equipped with a movable filtering material and a fan with a perforated tube for cleaning the filtering material from microalgae operating from a sensor mounted on the suction pipe pump unit.

Fig, 1 shows the BOX pond, a general view; in fig. 2 - intake device, side view; in fig. 3 - receiving device, top view.

BOX ponds contain a group of reservoirs 1 with inclined bottoms communicating by means of pipes 2 equipped with valves 3 and electric motors 4 with tank 5. In tank 5, on the slides 6, the frame of the intake device 7 is mounted, equipped with driven and driving rollers 8 and 9. rotation from the electric motor 10 through the chain transmission 11, and the electric motor 12 with the fan 13 and the perforated tube 14. driven by the leading and driving rollers the filter material 15 is placed above the funnel 16, having sidewalls 17 with the plates 18, about sealing them connected with a pivotally installed drainage pipe 19 with a water outlet 20 fixed on the suction pipe 21 with a sensor 22 and a pump unit 23 having an electric motor 24 with a motor control system 25 connected to a level relay 26 installed in a tank 5, and an electric motor ten.

Wastewater is supplied to the group of reservoirs 1 through pipes 2 having water outlets 27, valves 28 with electric motors 29 connected to electric motor control system 30. The motor control system 30 includes a program device 31, controlling valves 3 and 28 with electric motors 4 and 29. Motor control system 32, sensor 22 controls the operation of motor 12.

BOX pond works as follows.

Initially, the sewage of the six reservoirs 1 is filled with manual control of valves 3 and 28 with electric motors 4 and 29. After that, control of valves 3 and 28 with electric motors 4 and 29 is switched to automatic mode. At the beginning of the seventh day, the software device 31 closes the circuit of the motor control system 30 and opens the jaw 3 with the electric motor 4 of the first reservoir 1 and the valve 28 with the electric motor 29 of the seventh reservoir 1.

When the valve 3 is open, the disinfected wastewater from the first reservoir 1 goes through pipes 2 to reservoir 5. When the reservoir 5 is filled, the floats 6 pop up and the level switch closes the 2G system circuit;

0 motor controls, includes a pump unit 23 and an electric motor 10, resulting in rotation with the help of a chain transmission 11, a master 9 and a slave 8 rollers, and accordingly ъ filtering

5 material 15. Sewage water with microalgae entering the reservoir 5 from the first reservoir 1 is cleaned of microalgae, the passage through the filtering material 15 and entering the funnel 16

0 through the drainage pipe 19 and the outlet 20, fills the suction pipe 21 and is pumped out by the pump unit 23.

As the flow of waste water containing microalgae through the filter

5, the material 15 clogs its pores and a vacuum is formed in the suction pipe 21, then the sensor 22 is activated and closes the circuit of the motor control system 32 and switches on the electric motor 12, the fan 13 starts air supply

0 into the perforated tube 14 to purge the filter material 15 and release its pores from microalgae. When ke filtering material 15 from microalgae in the suction pipe 21

5, the vacuum is stopped and the sensor 22 opens the circuit of the motor control system 32 and turns on the electric motor 12 and the air supply by the fan 13 is stopped.

0After emptying the first reservoir 1

the level of waste water in the tank 5 decreases and the level relay 26 opens the circuit of the motor control system 25, turning off the motor 24, stopping

5, the operation of the pump unit 23, and the frame of the water intake device 7 placed on the floats 6, is lowered to the bottom of the tank 5.

Non-contaminated wastewater flows through pipes and gas outlets 27 with open valve 28 to the seventh reservoir 1 during the day. At the beginning of the eighth day, the software device 31 closes the circuit of the motor control system 30, including

5 work electric motors 4 and 29 v. closing the valves 3 and 28 of the first and seventh reservoirs and opening the valves 3 and 28 of the second and first reservoirs, the raw sewage is supplied to the first reservoir

1 and treated wastewater from the second 1 to the tank 5 through pipes 2,

This process is periodically repeated. When using the proposed BOX pond, microalgae are removed from treated wastewater when discharged into watercourses, preventing their contamination, and in addition, the use of manual labor during exploitation of BOX and ponds is excluded.
