Specific embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to make to protection domain of the present utility model Define.

Refering to shown in Fig. 1-Fig. 5, the utility model provides a kind of packed bed jet aeration tanks, by aeration tank pond body 1, filler Bed 2, water circulating pump 3, ejector 4, distributor 5 and connecting pipe composition, the top of aeration tank pond body 1 is provided with the He of water inlet 6 Delivery port 7, the middle part of the aeration tank pond body 1 is provided with partition wall 8, and the lower section of the partition wall 8 is provided with water hole 9；The water circulating pump 3 Intake is located at the lower section of packed bed 2；The two ends of the ejector 4 connect respectively water circulating pump 3 and distributor 5；The distributor 5 sets The bottom of pond body 1 in aeration tank, the distributor 5 by supervisor 5-1 and some bend pipe 5-2 constitute, bend pipe 5-2 one end be responsible for 5-1 phases Even, the end outlet of bend pipe 5-2 is sharp cone distal, and the bend pipe 5-2 is symmetrically interspersed in supervisor 5-1 both sides.

The ejector 4 is made up of nozzle 4-2, air entry 4-1, mixing chamber 4-3, trunnion 4-4 and anemostat 4-5, described Nozzle 4-2, mixing chamber 4-3, trunnion 4-4 and anemostat 4-5 set gradually, and the air entry 4-1 is located at the side of nozzle 4-2, The anemostat 4-5 is connected to distributor 5.

The water inlet 6 and delivery port 7 are located at the two ends of aeration tank pond body 1, and positioned at the top of packed bed 2.Sewage is from water inlet Mouth 6 enters aeration tank, and packed bed 2 is first from up to down passed through in vertical direction, flows through afterwards after water hole 9 again from bottom to top Through packed bed 2, Jing delivery ports 7 flow out, and complete whole handling process.

The water hole 9 is located at the bottom of partition wall 8 and away from aeration tank water inlet 6 and the side of delivery port 7.

Preferably, the supervisor 5-1 and bend pipe 5-2 is anticorrosion pipeline.

During normal operation, the activated sludge at aeration tank bottom 1 and the pressurization of mixed liquor Jing water circulating pumps 3 of sewage are promoted to and penetrate Stream device 4, Jing nozzles 4-2 sprays at a high speed, into mixing chamber 4-3, and forms local decompression in mixing chamber 4-3 and trunnion 4-4. Under differential pressure action, air Jing air entry 4-1 are inhaled in ejector 4, and with mixing chamber 4-3 in muddy water mixed solution Rapid contact Mixing mass transfer, the air-water mixture Jing anemostats 4-5 of formation introduces the supervisor 5-1 of distributor 5, and is sprayed by bend pipe 5-2.Cause Bend pipe 5-2 ends bore reduces, mixture velocity increase, Jing after bend pipe sprays, because inertia impulsive force forms eddy flow, disturbance in bottom of pond Pool bottom sludge, mixes to muddy water.So iterative cycles, realize carrying out sewage aeration aerating and stirring.

With fine gas bubbles rapid increase, flow velocity reduces the air that distributor 5 is discharged Jing after packed bed 2, outstanding in sewage The filled retention of float, suspended sludge utilizes oxygen and absorbs the organic contamination in sewage with the biomembrane for being attached to filler surface Thing carries out metabolism, is purified sewage.
