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 the device, especially to a device for purifying organic pollutants in water 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 purification system will caus...

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, such as Figure 4 As shown, it fixes the aeration equipment (aeration pipe) 25 at the bottom of the container by the bracket 28, and cannot change the air supply position with the movement of the biological bacteria bed 30, which makes it subject to other shortcomings / weaknesses: biological bacteria After the 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] Known biological purification treatment system of polluted water body and its used biological bacteria bed again, such as Figure 4 Shown, its aeration equipment 25 (separate with biological bacteria bed 30) is fixed on the bottom, and this just makes it be subject to a serious shortcoming: when aeration equipment (aeration pipe) 25 failures, if not the inside container 51 If the water and biological mud are emptied, it is difficult to repair or replace the equipment, but the emptying of pool water and biological mud will lead to the death of microbial flora and the collapse of the original biological purification system, which will cause the reconstruction of biological bacteria after the equipment is repaired. Waste of time and waste of required manpower and material resources
