Artificial wetland process for sewage treatment

Abstract

The invention provides an artificial wetland process for sewage treatment, and relates to the technical field of sewage treatment. According to the artificial wetland process for sewage treatment, flexible sheet membrane stack assemblies, flexible sheet membrane stack systems and ecological wetland assemblies are included, the flexible sheet membrane stack systems are connected with at least one flexible sheet membrane stack assembly, the flexible sheet membrane stack systems are connected in parallel and converged to be connected with at least one ecological wetland assembly, and each flexible sheet membrane stack assembly comprises an outer frame. A membrane branch is arranged in the outer frame, and a water production pipe is arranged on the left side of the membrane branch. By arranging the film membrane stack system and the ecological wetland, not only is effective purification treatment on sewage achieved, but also species symbiosis, a substance cyclic regeneration principle and a structure and function coordination principle in an ecological system can be achieved, and on the premise of promoting virtuous cycle of pollutants in wastewater, the production potential of resources is fully played, repollution of the environment is prevented, and the ecological wetland system has a wide application prospect. The optimal benefits of sewage treatment and recycling are obtained.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a constructed wetland technology for sewage treatment. Background technique [0002] Sewage treatment: The process of purifying sewage in order to make it meet the water quality requirements for discharge into a body of water or for reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and is increasingly entering the daily life of ordinary people. [0003] However, the structure of the existing sewage treatment device is complex, the construction cost is high, and transportation is inconvenient. At the same time, the traditional sewage treatment equipment has a complex structure and high technical content, and it is not convenient for non-professionals to regularly maintain it. Once the equipment is damaged Its maintenance cost ...
