Problems solved by technology

On the one hand, a large amount of tail water is discharged into the receiving water body, which brings high nitrogen and phosphorus pollution loads to rivers and lakes, causing negative impacts such as eutrophication, algal blooms, and water quality deterioration; on the other hand, due to the development of urban water resources High degree of utilization, insufficient ecological water, resulting in lack of water supply in urban landscape rivers, lakes, wetlands, etc., ecological degradation and other problems
The lack of effective use of tail water resources and the difficulty of ecological water use in urban rivers, lakes and wetlands have formed a huge contradiction
[0003] Existing urban tail water treatment technologies are usually realized by independent treatment units, and related technologies cannot be combined and optimized to form a system with integrated performance and better effect, so as to maximize the effect of tail water treatment

Abstract

The invention discloses an urban tail water composite unit type treatment device and method, and relates to the technical field of urban tail water treatment. The device comprises a lime clarification unit, an air floatation unit, a coagulation unit, an aeration oxygenation unit, an artificial wetland system unit and a carbon source unit. After urban tail water is treated by the units, the effects of reducing the content of suspended particles in the tail water, promoting nitrogen removal by biological denitrification, enhancing biological phosphorus removal and the like are achieved, the content of pollutants such as SS, nitrogen and phosphorus in the tail water is further reduced, and sufficient water source guarantee is provided for supplying urban landscape rivers and lakes.

Description

technical field [0001] The invention relates to the technical field of urban tail water treatment, in particular to a composite unit treatment device and method for urban tail water. Background technique [0002] Many urban landscape rivers and lakes are usually used as the final "receiving water body" for the effluent of sewage treatment plants, and bear the pollution load caused by the tail water discharge of urban sewage treatment plants. On the one hand, a large amount of tail water is discharged into receiving water bodies, which brings high nitrogen and phosphorus pollution loads to rivers and lakes, resulting in negative impacts such as eutrophication, algal blooms, and deterioration of water quality; on the other hand, due to the development of urban water resources The high degree of utilization and the lack of ecological water lead to problems such as lack of water supply and ecological degradation in urban landscape rivers, lakes, wetlands, etc. The lack of effec...
