A reaction-sedimentation integrated deep-water aeration tower and its treatment process

Abstract

The invention provides a reaction-precipitation integrated deep water aeration tower and a treatment process thereof. The deep water aeration tower comprises an aeration tower body, wherein an aeration tower inner cylinder is arranged at the upper part of an inner cavity of the aeration tower body, and a plurality of guide holes are formed in the side wall of the upper part of the aeration tower inner cylinder; a guide plate is arranged between the lower end of the aeration tower inner cylinder and the inner wall of the aeration tower body, and the inner cavity of the aeration tower body is divided into a precipitation area and a mixing reaction area by the aeration tower inner cylinder and the guide plate; an overflow weir groove is formed in the inner side wall at the top of the aerationtower body, and the distance between the overflow weir groove and the bottom surface of the aeration tower body is 9.5-10.5m. Water pressure at the bottom of the aeration tower body is increased by increasing the height of the aeration tower, saturated solubility of oxygen is increased, and the working efficiency is improved. The tower has a compact structure, the inside of the aeration tower isfunctionally partitioned by the guide structure in the aeration tower, so that the aerobic reaction and separation and precipitation of a mixed solution in the aeration tower are conducted in one device, the construction cost and the operation cost are reduced, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a reaction-sedimentation integrated deep-water aeration tower and a treatment process thereof. Background technique [0002] At present, with the continuous advancement of urbanization, urban construction land tends to be tight, and the requirements for space utilization are also constantly increasing. In the context of this kind of urban development, the sewage treatment facilities of sewage treatment plants are required to occupy as little land as possible. As a result, sewage treatment structures have gradually developed from the ground to the air or underground. Buried sewage treatment facilities are buried below the surface, and the landscape effect is better, but it is not conducive to maintenance, and if the anti-seepage and anti-corrosion are not proper, it will cause serious consequences of groundwater pollution, so it is more suitable for occasions where the a...
