Self-mixing type anaerobic ammonia oxidation baffle plate reactor

Abstract

The invention discloses a self-mixing type anaerobic ammonia oxidation baffle plate reactor which comprises a water bath heating system and a reactor body, wherein the water bath heating system is arranged on the reactor body and comprises a heater and a water bath heating layer; the water bath heating layer wraps the two side walls and bottom of the reactor body, and the heater is connected with the water bath heating layer; the reactor body comprises a water distribution area, a reaction area and a precipitation area; the water distribution area comprises a water inlet formed at the bottom of the reactor body; the reaction area is arranged above the water distribution area, multiple baffle plates are vertically arranged in the reaction area, and the reactor main body is divided into at least four cells in series connection by the baffle plates. By adopting the self-mixing type anaerobic ammonia oxidation baffle plate reactor disclosed by the invention, the wastewater mixing can be promoted, the problem of non-uniform microbial activity and number caused by non-uniform matrix distribution of the cells is effectively solved, and the overall reaction potential of the reactor is improved.

Description

technical field [0001] The invention relates to a self-mixing anaerobic ammonium oxidation baffled reactor. Background technique [0002] Due to the extensive use of chemical fertilizers and the discharge of industrial wastewater, the problem of water pollution is becoming more and more serious. Nitrogen pollution is one of the most serious problems. The eutrophication of the water body caused by the discharge of nitrogen into the water body leads to the deterioration of the water quality and the death of a large number of aquatic organisms. Anammox technology can effectively remove ammonia nitrogen and nitrite nitrogen in water bodies at the same time, and has the advantages of high efficiency, low cost, and low resource consumption. There are many kinds of anammox biological denitrification reactors, but there are some disadvantages, such as large proportion of dead zone in the reactor, weak shock resistance, and easy loss of anammox sludge. [0003] The anaerobic baffl...
