Example Embodiment

[0043] The first aspect of the present invention provides an improved batch batch reactor, which includes an anaerobic reaction unit, a first anoxic reaction unit, a mud-water separation unit, an aerobic unit, a first batch unit, a second batch unit, A pre-anoxic unit, a second anoxic reaction unit, a first anoxic / aerobic reaction unit and a second anoxic / aerobic reaction unit.

[0044] In this document, the modified sequential batch reactor is also referred to as an improved sequential batch reactor, which includes at least two sequential batch units. In the first half of a typical operation cycle, the raw water flows through the anaerobic reaction unit, the first anoxic reaction unit, the aerobic unit, the first anoxic / aerobic reaction unit and the first batch unit in sequence, and then flows into the mud-water separation The unit is separated into supernatant and bottom sludge. The bottom sludge is transported to the anaerobic reaction unit through the pre-anoxic unit. The sup...

Abstract

The invention provides a multi-unit modified sequencing batch reactor and an application thereof. The multi-unit modified sequencing batch reactor comprises an anaerobic reaction unit, a first anoxic reaction unit, a slurry separation unit, an aerobic unit, a first order batch unit and a second order batch unit, and the multi-unit modified sequencing batch reactor also comprises a pre-anoxic unit, a second anoxic reaction unit, a first anoxic/aerobic reaction unit and a second anoxic/aerobic reaction unit. The multi-unit modified sequencing batch reactor can fully utilize carbon sources in raw water and improve the removal rate of total nitrogen, is especially suitable for treating waste water with low carbon-nitrogen ratio, and can also be used for treating waste water with high carbon-nitrogen ratio.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment. Specifically, the invention relates to a multi-unit (especially 10 units) improved sequencing batch batch reactor and its application in sewage (especially sewage in southern China) treatment. [0002] technical background [0003] The inventor invented the improved sequencing batch batch reactor 20 years ago, which covers functions such as anaerobic / anoxic, aerobic, sequenced batch reaction, and precipitation effluent, and is convenient for multiple treatment chambers in a single box (abbreviated as One pool with multiple chambers or one pool with multiple units) form integration (see Chinese Patent No. ZL97196312.6). A typical improved sequencing batch batch reactor with one pool and five chambers includes an anaerobic reaction unit, a separation unit, a main aeration (aerobic) unit, and two sequential treatment (sequencing batch) units. During the operation cycle, one of the sequencin...
