Artificial wetland processing system constructed by ecological bags

Abstract

The invention provides an artificial wetland processing system constructed by ecological bags, which comprises a collecting tank, a wetland tank and a delivery tank, partition walls at the bottoms of the tanks, partition walls on the peripheries of the tanks, and partition walls among the tanks are constructed by the ecological bags; when the partition walls on the peripheries of the tanks and the partition walls among the tanks are piled up, the ecological bags on the same layer and among the bag layers are connected integrally by project connection buckles; a natural soil layer is arranged at the bottom of the wetland tank; emergent aquatic plants are planted on the natural soil layer; submerged plants are planted on the ecological bags at the underwater parts of the four walls of the wetland tank; terrestrial plants are planted on the ecological bags at the overwater parts; buoyant rafts are arranged on the water surface; buoyant raft aquatic plants are planted on the buoyant rafts. The artificial wetland processing system carries out the purification treatment on sewage through multiple effects of sedimentation, filtration, chemical precipitation, adsorption, decomposition, microbial metabolism, plant metabolism, plant root systems and the like, has the advantages of stereoscopic repair, high efficiency, no limitation from the field, environment protection and low carbon, convenience for construction, installation, maintenance and management, cost saving, and wide application prospect.

Description

technical field [0001] The invention relates to a constructed wetland treatment system, in particular to a comprehensive wetland treatment system constructed of ecological bags that combines the functional features of surface flow constructed wetlands and subsurface flow constructed wetlands. Background technique [0002] At present, with the rapid growth of population and the acceleration of urban modernization, the discharge of urban sewage has also increased sharply. The discharge of a large amount of organic matter contained in sewage into the water body will reduce the dissolved oxygen content in the water body, and even reach a deficit. Oxygen state, serious pollution of water bodies, damage to ecological balance. At present, the conventional treatment methods of urban sewage in my country are mainly aerobic biological treatment and anaerobic biological treatment. These methods have large investment, high energy consumption, many processing units, high requirements for...

AI Technical Summary

Problems solved by technology

These two types of constructed wetlands have the following problems: (1) The location is fixed and the area is large; (2) The investment is large and the construction period is long; (3) There are many factors affecting the growth of plants. Once they are not planted, they are not easy to remove and replace. ; (3) It takes a long time for early system debugging, plant cultivation, and microbial domestication, and it often takes 2-3 plant growth cycles to achieve the ideal operating state, which is inefficient; (4) Biological and hydraulic complexity increases the processing mechanism of wetland systems , process dynamics and the knowledge and understanding of influencing factors, the design operation parameters are not easy to calculate accurately, often due to improper design in the early stage, the effluent water cannot meet the design requirements
