Problems solved by technology

But the known plug-flow reactor (for example, baffle chamber anaerobic reactor, ABR) also has some deficiencies, the main aspects are: (1) the first reaction chamber of the reactor bears a local load far greater than the average load , a decrease in processing performance may occur
(2) The problem of how to distribute the water evenly

Embodiment Construction

[0015] In order to further illustrate the present invention, below in conjunction with embodiment is described in more detail.

[0016] figure 1 It is a schematic diagram of an embodiment of the heterogeneous internal circulation anaerobic reactor of the present invention. Multiphase internal circulation anaerobic reactor pool body 19 is divided into three internal circulation anaerobic reaction chambers 4, 5, 6 with two partition walls 16, and the structure of three single internal circulation anaerobic reaction chambers is the same, for An internal circulation anaerobic reaction chamber with a secondary reaction zone (hereinafter referred to as the reaction chamber).

[0017] In each reaction chamber, two three-phase separators 10, 9 are provided to form the lower I-level reaction zone and the upper II-level reaction zone respectively, and on the slopes of the two three-phase separators 10, 9, a Two settling areas, the gas collection pipe 12 is connected to the three-phase...

Abstract

The disclosed multiphase inner cycle anaerobic reactor comprises: at least two gas-sealed inner cycle anaerobic reaction chambers separated by separator and connected in series and contained a two-stage reaction zone, an opposite gas-lift tube, a gas collecting tube, a backflow tube, gas-liquid separators parallel on one gas exhaust pipe or output respectively, and a three-phase separator; and arranging a water guide plate on the inlet of reaction chamber and a gas stripping device on bottom of the air-lift. This invention has well flow pattern, mixed liquid, well microbe separated state, and other advantages.

Description

technical field [0001] The invention relates to an organic sewage treatment device, in particular to a multiphase internal circulation anaerobic reactor. Background technique [0002] Organic wastewater is an inevitable product of human social life, which requires effective treatment to reduce environmental pollution. At present, there are two types of biological treatment methods for various organic wastewater: anaerobic and aerobic. Compared with aerobic biological treatment, anaerobic biological treatment has more advantages, including low sludge yield, low energy consumption, energy recovery, etc. Therefore, anaerobic biological treatment technology is the most worthy of vigorous development in the field of sewage biological treatment. [0003] In the anaerobic biological treatment method, upflow anaerobic sludge bed (UASB) reactor is the most successful anaerobic biological treatment process so far, but it also has many shortcomings, such as operating at low temperatu...
