Flow direction switching type anaerobic ammonium oxidation baffle plate reactor

Abstract

The invention discloses a flow direction switching type anaerobic ammonium oxidation baffle plate reactor which comprises a reactor body, wherein the inner cavity of the reactor body is divided into a reaction region, a water distribution region and a settling region; the reaction region is divided into a plurality of grids by first vertical partition plates; a clearance is reserved between the first vertical partition plates and the upper end of the reactor body; the grids are divided into rising regions and dropping regions through combined type partition plates; the upper parts of the combined type partition plates are perpendicular parts, and the lower parts of the combined type partition plates are chamfer parts which are bent towards the rising regions by certain angles; a corresponding settling region is divided from the dropping region by a second vertical partition plate, and a sludge reflow seam is reserved between the second vertical partition plate and a gradually enlarged plate; the water distribution region is provided with a water inlet and a water outlet communicated with the outside; detachable gas collection covers are arranged at the top of the reactor body. The flow direction switching type anaerobic ammonium oxidation baffle plate reactor has the beneficial effects that sludge is convenient to add and collect; the reactor is difficult to block and runs stably; the gas tightness of the reactor is high; the problem of low microorganism activity caused by lack of matrixes in the tail grid of a conventional anaerobic ammonium oxidation baffle plate reactor is solved, and sludge running off due to hydraulic scouring is reduced.

Description

technical field [0001] The invention relates to a flow direction switching type anaerobic ammonium oxidation baffle reactor. Background technique [0002] With the development of industry, the problem of water pollution is becoming more and more serious, such as nitrogen pollution, which will directly threaten human health and the sustainable development of society. The eutrophication of water caused by the discharge of nitrogen into water will cause water quality to deteriorate, and there will be a large number of aquatic organisms. die. Sewage remediation has become a hot spot in this era. Biological denitrification is a new and effective sewage treatment technology. Anaerobic ammonia oxidation technology is one of the best representatives. This technology has the advantages of high efficiency, low cost, and low resource consumption rate. There are many types of anammox biological denitrification reactors, but there are some disadvantages, such as a large proportion of de...

Problems solved by technology

[0004] In order to solve the problem of low microbial activity in traditional anaerobic baffled reactors due to the excessive concentration of the matrix in the first compartment and the low microbial activity caused by the lack of matrix in the last compartment, the microorganisms are in a starvation state.
