Abstract

The invention provides a modular assembly type floating subsurface flow constructed wetland suitable for enhanced treatment of a discharge port. The floating subsurface flow constructed wetland is formed by mutually clamping a plurality of floating subsurface flow constructed wetland units; the perforated pipes of the adjacent floating underflow constructed wetland units are connected in series; during operation, water discharged from the discharge port enters the floating underflow constructed wetland unit through the water inlet pipe, is uniformly distributed through the perforated pipe close to one side of the water inlet end, is purified, is collected by the perforated pipe close to one side of the water outlet end, enters the next adjacent floating underflow constructed wetland unit, and is purified; finally, purified effluent is discharged to the bottom of the floating underflow constructed wetland unit through a water outlet pipe, and is further purified through an elastic filler arranged at the bottom of the floating underflow constructed wetland unit. The water surface space is fully utilized, land space occupation is avoided, the overall structure is stable, mounting, dismounting and maintenance are rapid and convenient, the overall shape is diversified, and the treatment effect is good.

Description

technical field [0001] The invention relates to the technical field of floating water constructed wetlands, in particular to a modular assembly type floating water submerged flow constructed wetland suitable for enhanced treatment of outlets. Background technique [0002] The pollution of discharge outlets around many rivers and lakes in my country is relatively serious. Even if the sewage discharge outlets are intercepted and blocked, the rainy season overflow pollution of combined discharge outlets and the first rain pollution of rainwater outlets are still serious. The effluent is subjected to intensive purification treatment. [0003] Constructed wetland is a natural sewage treatment engineering technology, which can be divided into surface flow constructed wetland and subsurface flow constructed wetland. The subsurface flow constructed wetland has strong purification ability per unit area, good heat preservation, little influence by temperature, and basically no energy ...
