Background

The black and odorous water body is a serious water pollution phenomenon, so that the water body completely loses the use function and influences the landscape and the life and health of human beings. With the improvement of living standard of human and the high-speed development of industry, the sewage amount received by natural water body far exceeds the self-purification capacity of the water body. In 5 years, the state vigorously treats the black and odorous water body of the river channel, and plays a great role in restoring the ecology. However, many black and odorous water treatments are carried out by a simple chemical coagulation sedimentation method, so that the water achieves the apparent effects of no black and odorous water and low suspended matter. In fact, ammonia nitrogen and total nitrogen in water are not removed, and dissolved oxygen in water is very low, so that the water is easy to carry out anaerobic blackening again. .

A backwashing drainage groove 14 is arranged above the filter material layer 10, a backwashing drainage pipe 12 communicated with the backwashing drainage groove 14 is arranged on the side wall of the main body 1, a water outlet groove 13 is arranged above the backwashing drainage groove 14, a water outlet pipe 11 communicated with the water outlet groove 13 is arranged on the side wall of the main body 1, and valves are arranged on the water inlet pipe 2, the backwashing water inlet pipe 3, the one-level gas backwashing air inlet pipe 4, the two-level backwashing air inlet pipe 5, the aeration pipe 6, the emptying pipe 7, the water outlet pipe 11 and the backwashing drainage pipe 12.

Adopt the utility model discloses during the removal ammonia nitrogen:

the valves on the backwash water inlet pipe 3, the primary gas backwash air inlet pipe 4, the secondary backwash air inlet pipe 5, the emptying pipe 7 and the backwash water outlet pipe 12 need to be closed. The valves on the water inlet pipe 2, the aeration pipe 6 and the water outlet pipe 11 are opened.

Sewage containing ammonia nitrogen is discharged into a water inlet distribution pipe 18 through a water inlet pipe 2, then the sewage is uniformly distributed in a buffering water distribution and gas distribution area 16 through the water inlet distribution pipe 18, the water quantity rises layer by layer, the sewage is filtered through a filter plate 15, then the filtered sewage overflows a supporting layer 9 and enters a filter material layer 10, and the ammonia nitrogen, COD and SS (suspended substances) in the water body are removed through the metabolism of nitrobacteria on the filter material layer 10 through biological carriers, mainly nitrobacteria, on the filter material layer 10; in the process, the aeration pipe 6 is used for aerating the filter material layer 10, and dissolved oxygen in the water body is improved under the aeration condition, so that oxygen is provided for nitrobacteria. The treated water overflows the filter material layer 10, enters the water outlet tank 13, and is discharged through a water outlet pipe 11 communicated with the water outlet tank 13.

When back washing is carried out:

because the biomembrane wrapped on the filter material layer 10 after decontamination becomes thicker and thicker, the resistance of water inflow and the resistance of aeration become bigger and bigger; meanwhile, dead microorganisms of the biological carriers generated by metabolism can be accumulated in gaps of the filter material layer 10 and need to be cleaned out in time.

At first, the valve that closes inlet tube 2 stops to intake in main part 1, and close the valve on the aeration pipe 6 simultaneously, then open one-level gas backwash intake pipe 4, valve on backwash drain pipe 12, advance the gas backwash process through aerifing in the main part 1, last 5min later, close valve one-level gas backwash intake pipe 4 and go up the valve, open second grade backwash intake pipe 5, valve on the backwash water inlet tube 3, get into the air water and unite the backwash, last completion backwash process about 10min, wash water enters into backwash water drainage tank 14, discharge this device through the backwash drain pipe 12 rather than the intercommunication and collect the processing. And after the cleaning is finished, closing valves on the secondary backwashing air inlet pipe 5, the backwashing water inlet pipe 3 and the backwashing water outlet pipe 12 in sequence.

In the utility model, as the optimization, the water inlet distribution pipe 18 and the backwashing air inlet distribution pipe 19 are shaped like Chinese character feng. When the device operates to feed water, the water inlet distribution pipe 18 adopts a Chinese character feng-shaped distribution pipe, and water can be distributed at the bottom of the buffering water and gas distribution area 16 in a point-to-point manner, so that short flow caused by rising of the fed water is avoided. When the device is reversely cleaned, the air inlet and distribution pipe 19 is backwashed in a shape like a Chinese character feng to quickly form a layer of air pressure rise to loosen the filter material layer 10, so that incomplete reverse cleaning caused by large local air volume is avoided.

Because the water enters from bottom to top, the water outlet groove 13 is arranged above the inside of the backwashing water drainage groove 14, the water outlet groove 13 is higher than the backwashing water drainage groove 14, and the elevation of the backwashing water drainage groove 14 is low during backwashing, so that the sewage can be prevented from entering the water outlet groove 13.

The utility model discloses in, as preferred, backwash water drainage tank 14's both sides be provided with energy dissipation stationary flow bars 17, energy dissipation stationary flow bars 17 can make the surface energy of aeration weaken, avoid too many suspended substance to get into out basin 13 in, influence out water quality of water.

The utility model discloses in, as preferred, the buffering water distribution gas distribution district 16 and the main part 1 lateral wall on the precoat layer 10 on all be provided with district's access hole 8.

The utility model discloses in, as preferred, second grade backwash intake pipe 5 be and set up porose aeration pipe on the pipe wall, and with second grade backwash intake pipe 5 embedded in bearing layer 9, after the one-level gas backwash, close valve on one-level gas backwash intake pipe 4, open second grade backwash intake pipe 5, valve on the backwash water inlet tube 3, get into the combined backwash of air water, with second grade backwash intake pipe 5 embedded in bearing layer 9 on filter plate 15, can avoid air current and backwash water simultaneously through the pressure that filter plate 15 caused suddenly increase in the twinkling of an eye and lead to stopping with the backwash fan that second grade backwash intake pipe 5 is connected, and after backwash water inlet tube 3 supplies water, the wind pressure obviously descends, adopt the backwash fan that the operating power is low to realize wasing, can do benefit to and practice thrift the power consumption.

In the present invention, preferably, the bottoms of the backwash water discharge tank 14 and the water discharge tank 13 are sloped toward the pipe openings of the water discharge pipe 11 and the backwash water discharge pipe 12 communicated with each other. Because long-term water and mud accumulated in the backwashing drainage tank 14 and the water outlet tank 13 can cause anaerobism, moss and the like can appear in partial areas, and the water outlet quality is influenced. The bottoms of the backwashing drainage grooves 14 and the water outlet grooves 13 are respectively inclined towards the pipe openings of the water outlet pipe 11 and the backwashing drainage pipe 12 which are communicated with the bottom of the backwashing drainage grooves, so that water can be drained rapidly, and the influence on water quality caused by fermentation and anaerobic caused by water accumulation is avoided.

Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
