Embodiment 1

[0027] Example 1, such as figure 1 As shown, the integrated micro-power sewage processor based on the UASB reactor includes a tank body 1 and a water inlet pipe 32 . The water outlet end of the water inlet pipe 32 extends into the tank body 1 . The tank body 1 is provided with a drainage area, a steam-water separation area 4 and a biochemical reaction area 5 sequentially from top to bottom. The drainage area includes an outlet weir 2 . The water outlet weir 2 is an annular structure arranged around the inner wall of the tank body 1 , and the water outlet weir 2 is fixed on the inner wall of the tank body 1 .

[0028] The tank body 1 is also provided with a central cylinder 33 and an aeration device. The central cylinder 33 is arranged at the central axis of the tank body 1 , and the lower end of the central cylinder 33 protrudes into the biochemical reaction zone 5 near the bottom of the tank body 1 . The upper end of the central cylinder 33 is set higher than the height o...

Abstract

The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated micro-power sewage treater based on a UASB reactor. The sewage treater comprises a tank body and a water inlet pipe, wherein a drainage area, a steam-water separation area and a biochemical reaction area are sequentially arranged in the tank body from top to bottom, and a central cylinder of which the upper end overhangs to be higher than the water level of the drainage area and the lower end overhangs into the biochemical reaction area and an aeration device located in the biochemicalreaction area are further arranged in the tank body; a steam-water separator and at least one gas stripping pipe connected to the steam-water separator are arranged in the steam-water separation area,the water outlet end of the gas stripping pipe extends into the central cylinder to achieve nitrification liquid backflow, and the gas stripping pipe is provided with a gas stripping adjusting valveused for adjusting the nitrification liquid backflow amount. By arranging the gas stripping pipe, the aeration device and the central cylinder, backflow of nitrification liquid is achieved, and the gas stripping adjusting valve is arranged on the gas stripping pipe, so that the backflow amount of the nitrification liquid is adjusted.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated micro-power sewage processor based on a UASB reactor. Background technique [0002] There are continuous and intermittent biochemical treatment of sewage. Continuous treatment generally uses biochemical tanks and secondary sedimentation tanks as monomers. The biochemical tank is in the form of a rectangle, and the secondary settling tank is in the form of circular radial flow, which can make full use of the sedimentation principle. Biochemical reaction tanks for batch treatment, such as CASS tanks, are generally divided into several cycles per day, and each cycle consists of steps such as water intake, aeration, sedimentation, and standing. For these two forms of biochemical treatment, there are generally many structures, high lifting heights, and relatively large floor area. [0003] The integrated sewage treatment equipment integrates vario...
