Abstract

The invention relates to a sequencing batch jet-flow driven biochemical reactor, which comprises a reaction tank, a water inlet pipe, an immersible pump, a first-grade suction jet device with a double-gas-channel annular nozzle, a mixed solution guide pipe, a second-grade multi-nozzle radial jet-flow aerator, a gas supply device, a buoyancy driven water decanter and a driving winch of the water decanter; the first-grade suction jet device with the double-gas-channel annular nozzle is provided with an annular nozzle and inner and outer gas channels; the second-grade multi-nozzle radial jet-flow aerator is installed in the centre of the bottom of the reactor; the buoyancy driven water decanter is installed on the wall of the reaction tank over the horizon line of the reactor; and the driving winch of the water decanter is used for packing up or down the buoyancy driven water decanter through a driving rope. The sequencing batch jet-flow driven biochemical reactor disclosed by the invention can be used for increasing the aeration efficiency, accelerating the dynamic circulation of dynamic water and greatly increasing the mass transfer rate in the biochemical reaction process, so that the biochemical reaction efficiency is increased; and furthermore, the sequencing batch jet-flow driven biochemical reactor disclosed by the invention can also be used for treating various types of sewage, and can be flexibly combined with other sewage treatment processes.

Description

Technical field [0001] The invention relates to a biochemical reactor for sewage purification, in particular to a jet-driven sequential batch biochemical reactor. Background technique [0002] There are many types of biochemical reactors in sewage treatment facilities, and the sequencing batch activated sludge biochemical reactor is the most widely used one. The biochemical reactor has strong impact load resistance, good suppression effect on sludge expansion, high microbial activity, and can treat refractory organic matter. The process is simple, the investment occupies less area, and the operating cost is low. The operation and management are simple, the effluent quality is good, and it has the function of nitrogen and phosphorus removal. However, in terms of aeration, oxygenation, and decanting equipment technology, the biochemical reaction rate is restricted from further increasing, and the sewage purification efficiency of the currently used sequencing batch activated slud...
