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 purifying sewage, in particular to a jet-driven sequencing batch biochemical reactor. Background technique [0002] There are many forms of biochemical reactors in sewage treatment facilities, and the sequencing batch activated sludge biochemical reactor is one of the most widely used. This kind of biochemical reactor has strong shock load resistance, good effect on sludge expansion inhibition, high microbial activity, and can process refractory organic matter. The process is simple, the investment occupies less land, and the operation cost is low. The operation and management are simple, the effluent water quality is good, and it has the function of nitrogen and phosphorus removal. However, in terms of aeration, oxygenation and decanting equipment technology, the further improvement of the biochemical reaction rate is restricted, and there is still a large room for improvement in the sewage purifica...
