Description

Sludge precipitation NMBR reactor

Technical Field

The utility model belongs to the sludge treatment field, concretely relates to sludge sedimentation NMBR reactor.

Background

With the development of domestic economy, more and more sewage appears in the production and living processes, and the demand for sewage treatment is greater and greater, which means that the process for sewage treatment is required to be efficient, and the direct result of the high efficiency is that the occupied area of the process is reduced.

However, the most common method is a secondary sedimentation tank at present, namely, sludge is firstly precipitated and then the precipitated sludge is transferred into an aeration tank.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide a sludge settling NMBR reactor.

The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:

a sludge sedimentation NMBR reactor comprises a reactor body, a bracket arranged at the top of the reactor body and used for being connected with an aeration tank, a water outlet weir arranged in the reactor body, a sludge discharge channel arranged at the lower end of the reactor body, a sludge discharge port arranged at the lower end of the sludge discharge channel and a water inlet arranged at the outer side of the reactor body and communicated with the reactor body; the two ends of the water outlet weir are fixed on the reactor body.

Reinforcing plates are arranged on two sides of the reactor body; the water inlet is arranged on the reinforcing plate; the interior of the reinforcing plate is a sewage channel; the sewage channel is communicated with the bottom of the reactor body.

The water inlets are uniformly distributed; the water inlet is square.

The sludge discharge channel is conical.

The sludge discharge port is a 90-degree straight outlet.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a sludge precipitation NMBR reactor utilizes the support can arrange its whole aeration tank in, the effectual area that has reduced, because it is overall design, easy to assemble and demolish moreover, improves its utilization ratio itself. When in use, the sludge sedimentation NMBR reactor is arranged in an aeration tank, and sewage enters the reactor body from the water inlet to carry out natural sedimentation; the settled sludge directly enters the aeration tank from the sludge discharge port through the sludge discharge channel for further treatment, and clear water is discharged from the water outlet weir, and the operation is repeated in cycles and continuously circulated, so that the function of the original secondary sedimentation tank is completed.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 1-2 show a sludge-settling NMBR reactor, which comprises a reactor body 2, a bracket 1 arranged at the top of the reactor body and used for being connected with an aeration tank, a water outlet weir 7 arranged in the reactor body, a sludge discharge channel 4 arranged at the lower end of the reactor body, a sludge discharge port 5 arranged at the lower end of the sludge discharge channel, and a water inlet 31 arranged outside the reactor body and communicated with the reactor body; the two ends of the water outlet weir are fixed on the reactor body through bolts 6. Reinforcing plates 3 are arranged on two sides of the reactor body; the water inlet is arranged on the reinforcing plate; the interior of the reinforcing plate is a sewage channel; the sewage channel is communicated with the bottom of the reactor body. The water inlets are uniformly distributed; the water inlet is square. The sludge discharge channel is conical. The sludge discharge port is a 90-degree straight outlet.

The principle of the utility model is that: placing the sludge precipitation NMBR reactor in an aeration tank, and allowing sewage to enter a reactor body from a water inlet for natural precipitation; the settled sludge directly enters the aeration tank from the sludge discharge port through the sludge discharge channel for further treatment, and clear water is discharged from the water outlet weir, and the operation is repeated in cycles and continuously circulated, so that the function of the original secondary sedimentation tank is completed. The NMBR technology has stable flow state of mixed liquor, good sludge property, easy formation of granular sludge and excellent settling property; after being placed in an aeration tank, the reactor can integrate reaction and precipitation, has high sludge concentration, short hydraulic retention time, small occupied area and less equipment investment; the sludge is unpowered and flows back completely, the energy-saving effect is obvious, and the operating cost is low; the system has the advantages of quick start, stable operation, strong impact load resistance and convenient management. The core equipment has no easily damaged parts, and the service life is free from maintenance. Investment is saved: the land occupation is small, the civil engineering is less, the pipe network is less, the excavation of the lake bottom is not needed, and the investment is greatly saved; compared with the traditional process, the noise is very small, and the sound environment around the water body is not influenced; the operation and maintenance are simple, only the startup and shutdown are needed, and no special person is needed to take care of; the construction period is short, the installation can be carried out when water exists or not, and the construction period is short; no secondary pollution and environmental protection.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
