Environment-friendly flood drainage channel water quality purification system

Abstract

The invention discloses an environment-friendly flood drainage channel water quality purification system. According to the technical scheme, the system comprises a plurality of filter screen boxes arranged in the length direction of a reinforced flood drainage channel, a filter material is detachably arranged in each filter screen box, the filter material comprise ceramsite or gravel filled in the filter screen boxes, an ecological floating island is arranged between every two adjacent filter screen boxes, a sedimentation tank is arranged at each filter screen box in the reinforced flood drainage channel, an artificial waterweed blanket used for bearing pollution-resistant bacteria or algae is laid at the bottom of the reinforced flood drainage channel, and the reinforced flood drainage channel comprises a capillary crystalline concrete member. According to the scheme provided by the invention, the water quality purification system based on the reinforced flood drainage channel with a stable structure and good durability is simple, efficient, practical, economical, easy to maintain and capable of effectively intercepting nutrient elements such as N, P and the like in water, so that the problem of serious eutrophication of a water body is restrained.

Description

technical field [0001] The invention relates to the field of ecological environment, in particular to an environment-friendly flood drainage canal water purification system. Background technique [0002] At present, eutrophication water pollution treatment technologies mainly include chemical treatment, physical treatment and biological treatment. Chemical treatment requires the addition of a large amount of chemicals, which is costly and likely to cause secondary pollution; physical restoration measures mainly include engineering methods such as sediment dredging, water diversion and water exchange, and the absolute amount of nutrients in the restoration process has not been reduced. Fundamentally solve the problem; biological treatment technologies such as artificial wetlands and biological floating islands construct aquatic plant systems in situ, and use the adsorption and absorption of plant roots to reduce nutrients such as nitrogen and phosphorus in the water, thereby ...

Problems solved by technology

However, in the prior art, since the height of the water flow in the river is not stable, soil culture plants are planted directly on the embankment, and the plants are easily submerged after the water rises. When the water level drops, the submerged plants need to be replanted, resulting in a workload. In addition, the durability of the reinforced flood discharge channel of the existing technology is not good, and there is room for improvement
