Embodiment 1

[0022] Such as figure 1 , a sewage treatment device beneficial to biological activity, comprising a closed pressure vessel with elliptical heads at both ends, three partitions 14 are arranged along the axial direction of the pressure vessel, and the partitions 14 divide the interior of the pressure vessel It is the first oxidation chamber 4, the second oxidation chamber 5, the mixing chamber 16 and the settling chamber 11 in succession. The partition plate 14 is provided with through holes through both sides. The first oxidation chamber 4 and the second oxidation chamber 5 are equipped with biological filler 6;

[0023] It also includes a feeding flange 7 provided on the surface of the pressure vessel, and a box bottom plate 10 is also arranged in the mixing chamber 16, and the box bottom plate 10 surrounds the upper part of the mixing chamber 16 to form a flocculant box 9. The feeding method The blue 7 communicates with the flocculant box 9, the bottom plate 10 of the box is...

Embodiment 2

[0028] The present embodiment is further limited on the basis of embodiment 1, as figure 1 , in order to facilitate the maintenance and inspection of the accessories in each chamber, it also includes a plurality of inspection holes 3 arranged on the pressure vessel shell, and the inspection holes 3 are respectively connected with the first oxidation chamber 4, the second oxidation chamber 5 and the settlement The chambers 11 communicate with each other, and the inspection holes 3 each include a connecting flange, a connecting pipe and a blind plate screwed on the connecting flange, and the two ends of the connecting pipe are respectively connected with the pressure vessel shell and the flange.

[0029] Because the present invention can be installed underground, in order to facilitate the strength of the weak part of the present invention, the connecting pipe is welded and connected with the pressure vessel shell, and the pressure vessel shell is also welded with reinforcing rin...

Abstract

The invention discloses a sewage treatment device beneficial to bioactivity. The sewage treatment device comprises a sealed pressure vessel, wherein two ends of the sealed pressure vessel are provided with elliptical sealing heads; three partition plates are arranged along the axial direction of the pressure vessel; the inside of the pressure vessel is sequentially divided into a first oxidizing chamber, a second oxidizing chamber, a mixing chamber and a settling chamber by using the partition plates; through holes passing through two sides are uniformly formed in the partition plates; and the first oxidizing chamber and the second oxidizing chamber are respectively filled with biological stuffing. The treatment device is high in intensive degree, good in sewage treatment effect and difficult to generate leakage pollution and can be mounted underground.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device beneficial to biological activity. Background technique [0002] At present, water resources are one of the problems that countries all over the world are facing urgently. According to the research report of the United Nations World Resources Institute, the world's water resources are facing a more severe situation than other resources and in the past in terms of quality and quantity. According to statistics, the annual industrial water consumption in the world is trillions of m3, and the situation of this phenomenon is very different in different parts of the world. The demand is extremely incompatible with the limited available water resources, and the industrial and domestic wastewater discharged to natural water bodies in the world every year is also Hundreds of billions of m3, causing more than 35% of fresh water resources to be polluted, so it will...
