Device combining air feeding and biological connection and the formed water purifying system

Abstract

The present invention provides a device to combine air supply and biological contact that can be applied to purify the pollutants in water. The device to combine air supply and biological contact includes an air vent structure; a biological contact structure to connect the air vent structure; a device externally connected structure to connect the biological contact structure arranged between the device externally connected structure and the air vent structure; and a ventilating structure to connect the air vent structure and transport air to the air vent structure.

Description

technical field [0001] The present invention relates to a device that combines air supply efficiency and biological contact effect, and also relates to a system for purifying pollutants in water using this device, especially to a system for purifying organic pollutants in water using this device system. Background technique [0002] The gas supply of the biological purification treatment system known to pollute the water body is fixed aeration equipment, which fixes the aeration pan or aeration tube to the bottom of the waste water tank (close to the bottom surface or in contact with the bottom surface), or uses jet aeration The machine is fixed on the wall of the pool; it has a serious shortcoming: when the aeration equipment fails, the pool water and bio-sludge need to be drained before the equipment can be repaired or replaced, but the emptying of the pool water and bio-sludge will lead to microbial flora Death and the disintegration of the original biological purificati...

Problems solved by technology

According to the biological purification treatment system of this known polluted water body, the biological bacteria bed 30 can become automatic floating with the water level in the container 51 and the flow velocity, then will move to any position in the container vertically and horizontally, its movement Uncontrollable, especially multiple (in fact all) bacteria beds 30 will move in the same direction with the water flow, so they are densely packed in one place, which makes it subject to some disadvantages / weaknesses: accumulation in the downstream of the water flow due to water flow In places, the distribution of microbial carriers is uneven, and the local excessive accumulation will of course reduce the purification effect and treatment capacity, and even cause the microbial film "film plume" to block the flow of water, and even lead to the increase of the back pressure of the water flow, resulting in microbial carrier The deformation, cracking, and fragmentation of the biofilm can easily lead to the detachment of the microbial film due to floating and collision, fatally reducing or paralyzing the purification treatment capacity

[0005] Known biological purification treatment system of polluted water body and its used biological bacteria bed, as shown in Figure 4, it is fixed on the container bottom by support 28 with aeration equipment (aeration pipe) 25, can not follow biological bacteria bed 30 Change the air supply position due to the movement of the air, which makes it subject to other shortcomings / weaknesses: after the biological bacteria bed 30 moves with the water flow or wind direction, it can no longer effectively contact the air released by the aeration equipment (aeration pipe) 25 , and may even die collectively, with serious consequences

[0006] The biological purification treatment system of known polluted water body and its used biological bacteria bed again, as shown in Figure 4, its aeration equipment 25 (separate with biological bacteria bed 30) is fixed on the bottom, and this just makes it subject to a Serious shortcoming: when the aeration equipment (aeration pipe) 25 fails, if the water and biological mud in the container 51 are not emptied, then it is difficult to repair or replace the equipment, but the emptying of the pool water and the biological mud will lead to microorganisms The death of the bacteria group will cause the original biological purification system to collapse, which will cause a waste of time for rebuilding the biological bacteria after the equipment is repaired, and a waste of manpower and material resources required
