Embodiment 1

[0088] Such as figure 1 As shown, the present embodiment provides an anaerobic bioreactor, including unit modules B200 and unit modules A100 connected in series alternately in sequence, that is, unit module B200, unit module A100, unit module B200, unit module A100, unit module B200, The unit modules A100 are sequentially connected in series. And the unit module A100 and the unit module B200 are arranged and installed in an upper-lower alignment manner.

[0089] Such as figure 2 with image 3 As shown, four deflectors A101 are arranged in the unit module A100, and the four deflectors A101 divide the unit module A100 into a reaction zone Re, a water inlet zone In and a water outlet zone Ex, and the water inlet zone In is located at the side of the unit module A100. On the left and right sides, the water outlet area Ex is located in the middle of the unit module A100, and the reaction area Re is located between the water inlet area In and the water outlet area Ex. In this e...

Embodiment 2

[0097] Such as Image 6 with Figure 7 As shown, the present embodiment provides a sewage treatment device, including an anaerobic bioreactor, and also includes a pulse water inlet system 600 and a sedimentation tank 700. The pulse water inlet system 600 is located above the anaerobic bioreactor, and is connected with the unit module The water inlet area In of B200 is connected; the sedimentation tank 700 is located below the anaerobic bioreactor, the upper end of the sedimentation tank 700 is provided with an outlet pipe 701 , and the lower end of the sedimentation tank 700 is provided with a sludge discharge pipe 702 . The anaerobic bioreactor may have the structure of the anaerobic bioreactor described in Example 1, and may also be slightly different from Example 1 in terms of arrangement and number of unit modules.

[0098] On the basis of the above embodiments, further, a cover plate 800 is provided on the upper end of the sewage treatment device.

[0099] On the basis ...

Embodiment 3

[0101] This embodiment provides a sewage treatment device. The difference from Embodiment 2 is the pulse water inlet system 600, and the rest are the same as Embodiment 2.

[0102] For the sewage entering continuously by gravity, the pulse water inlet system 600 includes a pulse siphon water inlet device, which includes a pulse siphon water inlet tank and double siphon pipes with variable cross-sections. Not only is it easy to realize regular and quantitative intermittent pulse water intake, such as using a water intake method with a water intake time of less than 65 seconds and an interval of more than 15 minutes; it can also maximize the use of fluid potential energy, increase drainage capacity, reduce noise, and reduce energy consumption.

[0103] The working principle of the sewage treatment plant of the present embodiment is:

[0104] External sewage flows into the pulse siphon water inlet device by itself. After reaching the set water level, it is quantitatively discharg...

Abstract

The invention belongs to the technical field of sewage treatment and particularly relates to an anaerobic bioreactor and a sewage treatment device utilizing the same. The anaerobic bioreactor provided by the invention comprises a unit module A and a unit module B which are sequentially and alternately communicated in series; a plurality of flow guiding plates A are arranged in the unit module A so as to divide the unit module A into a reaction region, a water inlet region and a water outlet region; and a plurality of flow guiding plates B are arranged in the unit module B so as to divide the unit module B into a reaction region, a water inlet region and a water outlet region. The sewage treatment device provided by the invention comprises the anaerobic bioreactor. The anaerobic bioreactor has the beneficial effects that the occupied area is small, the investment is saved, the cost is low, the hydraulic retention time is short, the treatment efficiency is high, and the equalization, standardization and suit of the device are realized.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an anaerobic bioreactor and a sewage treatment device using the reactor. Background technique [0002] With the rapid development of my country's economy, the amount of wastewater generated by industrial production and residents' life has also increased rapidly, and the problem of water pollution has become increasingly prominent. The treatment of industrial wastewater and urban domestic sewage has become an important task. Sewage anaerobic biological treatment technology uses the metabolism and characteristics of anaerobic microorganisms to produce valuable energy-biogas while reducing organic matter without providing external energy. Therefore, it is currently economical and effective. One of the important ways to effectively solve the organic sewage treatment. [0003] There has been great progress in the development and research of anaerobic treatment te...
