Abstract

The invention belongs to the technical field of environmental protection, and specifically relates to an artificial wetland sewage treatment system. According to the invention, a horizontal undercurrent artificial wetland, an upstream vertical undercurrent wetland and a downstream vertical undercurrent wetland are mutually switched through simple valve opening and closing operations, and sewage can be circularly treated under the effect of a circulating pump. Meanwhile, a matrix is divided into a plurality of small units by adopting net cages to agilely combine the matrix and plants in the wetland. Compared with a single type artificial wetland, the removal process of pollutants can be enriched, the advantages of various types of artificial wetlands can be effectively utilized, the pollutant treatment efficiency is effectively improved, and the service life of the wetland is prolonged, so that the system has remarkable advantages in the field of sewage treatment. Three types of artificial wetlands can be used in series to treat same type of sewage, the three types of artificial wetlands can be alternately used, and the matrixes in different types and plants in the wetlands are agilely combined and paired to use by adopting the net cages.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a combined artificial wetland sewage treatment system. Background technique [0002] Water is a necessary condition for the existence of life and economic development, and it is also an important part of human tissue. However, human activities will cause a large amount of industrial, agricultural and domestic waste to be discharged into the water, polluting the water body. Around the world, more than 420 billion cubic meters of sewage are discharged into rivers, lakes and seas every year, polluting 5.5 trillion cubic meters of fresh water, which is equivalent to more than 14% of the total global runoff. Increasing water pollution has posed a major threat to human survival and has become a major obstacle to human health, economic and social sustainable development. Therefore, sewage treatment is an important issue related to the national economy and pe...
