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 explained below in conjunction with the drawings:

[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 reaction chamber 1 located at the far left end, and the reaction chamber 1 located at the far right end is connected with a solid-liquid separator 3. Connected. The solid-liquid separator 3 is a non-distance-shaped container with a water outlet 4 on its upper part, and the separated sewage is discharged from the water outlet 4. A sludge return outlet 5 is provided at the bottom of the solid-liquid separator 3, which is connected to the sludge return inlet 6 at the top of each reaction chamber 1, and the separated and treated sludge in the solid-liquid separator 3 is returned from the sludge return outlet 5 Return to the top of each reaction chamber 1, enter the reaction chamber 1 from the sludge return inlet...

Abstract

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-liquidseparator 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 inventionhas 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 hasthe advantages of low capital investment and running cost, high separating efficiency and good output water quality.

Description

Technical field [0001] The invention relates to a sewage treatment equipment with anaerobic biochemical technology. Background technique [0002] At present, since the 1970s, wastewater anaerobic treatment technology has developed rapidly due to its low investment, low operating cost, and energy (biogas) that can be recycled for investment. The flow anaerobic sludge bed reactor (UASB) is a second-generation anaerobic reactor treatment technology that can retain a large amount of microbial solids. The microbial retention capacity of this batch of reactors makes the volume of the reactor large Reduced, processing capacity and processing effect are greatly improved. At present, these technologies still have certain problems in some aspects or need to be further studied. For example, the key technology of UASB is the reasonable design of the three-phase separator and the successful cultivation of granular sludge with good performance. However, the design of the domestic three-phase...
