Problems solved by technology
[0006] (2) Suspended sludge is easy to lose, especially when the water flow changes, there is a phenomenon of mud running
[0007] (3) There is no liquid return separation device
[0008] (4) Due to the low sludge concentration and low unit treatment rate, the cost of large structures increases accordingly

Embodiment Construction
[0023] The present invention will be further described below in conjunction with accompanying drawing:
[0024] Such as figure 1 As shown, the present invention is composed of a plurality of reaction chambers 1 connected in series. A water inlet 2 is provided at the lower end of the leftmost reaction chamber 1, and the rightmost reaction chamber 1 is connected with a solid-liquid separator 3. connected. The solid-liquid separator 3 is a non-distance container, and a water outlet 4 is arranged on its upper part, and the separated sewage is discharged from the water outlet 4 . The bottom of the solid-liquid separator 3 is provided with a sludge return outlet 5, which is connected to the sludge return inlet 6 at the top of each reaction chamber 1, and the sludge separated and treated in the solid-liquid separator 3 is discharged from the sludge return outlet. 5 returns to the top of each reaction chamber 1, and enters the reaction chamber 1 from the sludge return inlet 6 at the...

The invention relates to a baffling contact precipitation integral anaerobic reactor which is characterized by consisting of a plurality of reaction chambers that are communicated and connected with each other in series, wherein, one reaction chamber positioned at the end part is provided with a water inlet, and another reaction chamber positioned at the other end is connected with a solid-liquid separator which is provided with a water outlet; the upper parts of the reaction chambers are provided with filler, and the adjacent reaction chambers are separated by a traverse baffle. The invention has the characteristics of simple technique, less investment, low running cost and the like; compared with the traditional anaerobic digester, the anaerobic reactor needs no mechanical stirring device and secondary sedimentation tank; compared with UASB and IC, the anaerobic reactor needs no expensive water inlet system and triphase separator with complicated design. Therefore, the invention has the advantages of low capital investment and running cost, high separating efficiency and good output water quality.
Description
technical field [0001] The invention relates to sewage treatment equipment by anaerobic biochemical technology. Background technique [0002] At present, since the 1970s, the anaerobic treatment technology of wastewater has developed rapidly because of its characteristics of low investment, low operating costs, and the ability to generate energy (methane) that can be invested and recycled, and a number of higher-than-liter technologies have emerged. Flow anaerobic sludge bed reactor (UASB) is a second-generation anaerobic reactor treatment technology that can retain a large amount of microbial solids. The ability of these reactors to intercept microorganisms makes the volume of the reactor greatly The processing capacity and processing effect are greatly improved. At present, these technologies still have certain problems in some aspects or need further in-depth research. For example, the key technology of UASB is the reasonable design of the three-phase separator and the ...
