Problems solved by technology
[0003] At present, the biochemical oxygenation devices in sewage treatment projects all use blower devices, which generally exist: the general water level of the blower oxygenation is 4m~5m. If the pressure of the blower is not enough, its oxygenation stroke is short. Press down several pieces and put them together to form large bubbles with lighter specific gravity. The oxygen molecules in the oxygenation will quickly surface, resulting in waste of energy; Power consumption doubles the operating cost; due to the use of a blower, it must be equipped with an aeration head to supply air to a large area, and the aeration head is easy to block, resulting in air flow interruption and uneven oxygen supply. It is carried out under the condition of removing the liquid in the sewage tank, resulting in long pipeline repair time, high maintenance cost and high maintenance technical requirements, which directly affects the use efficiency

Embodiment Construction
[0007] Take the 8m pool as an example below in conjunction with accompanying drawing, the present invention will be further described:
[0008] See figure 1 , the high-concentration biochemical aerator is set in the 8m deep biochemical tank 9, the sludge pump 10 sludge pump inlet pipe 10-1 enters the biochemical tank 9 sludge layer 8, and the sludge pump 10 of the sludge pump 10 The sludge pumping pipe 10-2 Connect the negative pressure chamber 1, the side of the negative pressure chamber 1 is provided with an air channel 1-1, the lower end of the negative pressure chamber 1 is fixed in the order of the air-water mixing pipe 2, the primary compression pipe 3, the secondary compression pipe 4, and the air-water diffusion pipe 5 Connect, the side of the lower end of the air-water diffusion pipe 5 is provided with 4 spouts 6 evenly arranged on the circumference, and 1 spout 7 at the bottom of the pool faces the bottom of the pool.
[0009] See figure 1 , energized, the sludge p...

The present invention discloses a high concentration biochemical aerator which comprises a pump, an inlet pipe, an outlet pipe, a gas-water mixing tube and a nozzle, and is fixed connected in an order of a gas-water mixing tube, a first compression pipe, a second expanding-contracting pipe, a gas-water spreading pipe and a nozzle, wherein the middle parts of the first compression pipe and the second expanding-contracting pipe are contracted, while the two ends of which have a bell-mouthed shape. The liquid level of the biochemical tank is generally more than 8 m, and the volume of the biochemical tank is increased, so that the travel of the air microbubble is doubled and the oxygen utilization ratio is up to 60% which is four times larger than that of the prior art, besides the generated biochemical sludge welters in the tank, and the investment is saved. The noise is low, so that rigorous soundproof device is not needed. The operation is convenient, the maintenance cost is low and the maintenance time is 90% shorter than that of the blower. The removal percentage is high and the removing effect is stable for removing CODcr and BOD5 from water.
Description
[0001] 1. Technical field: [0002] The high-concentration biochemical aerator of the present invention relates to the technical field of sewage treatment, in particular to the technical field of oxygenation devices, and is applied to sewage treatment projects, biochemical pools, regulating pools, etc. for oxygenation. 2. Background technology [0003] At present, the biochemical oxygenation devices in sewage treatment projects all use blower devices, which generally exist: the general water level of the blower oxygenation is 4m~5m. If the pressure of the blower is not enough, its oxygenation stroke is short. Press down several pieces and put them together to form large bubbles with lighter specific gravity. The oxygen molecules in the oxygenation will quickly surface, resulting in waste of energy; Power consumption doubles the operating cost; due to the use of a blower, it must be equipped with an aeration head to supply air to a large area. It is carried out under the condi...
