Problems solved by technology

The removal of phosphorus in sewage by wetland microorganisms is achieved through the assimilation and absorption of phosphorus and the accumulation of phosphorus-accumulating bacteria. Because there is no obvious sludge discharge in wetlands, the phosphorus in the microorganisms can be said to be a cyclic process and has no substantial effect.

Embodiment Construction

[0035] The present invention is further described below by specific implementation case:

[0036] When a plant configuration method that improves the quantity and activity of wetland microorganisms is applied to downward filter type wetlands and horizontal subsurface flow wetlands, it can make the water quality conditions and microbial communities in different spatial divisions have a significant difference, illustrating that the plant of the present invention The configuration has significantly improved the types and activities of wetland microorganisms.

[0037] This implementation case is a compound artificial wetland used in series connection of downward filtering wetland and horizontal subsurface flow wetland. It is a rural domestic sewage wetland treatment project. The downward filtering wetland covers an area of ​​about 50m 2 , the horizontal subsurface flow wetland covers an area of ​​about 60m 2 . The wetland was officially put into use in March 2013. After three se...

Abstract

The invention discloses a plant configuration method for improving the quantity and the activity of wetland microbes. The method is characterized in that shallow-rooted wetland plants, medium-rooted wetland plants and deep-rooted wetland plants are planted in the matrix of a constructed wetland at intervals; and the root system of the shallow-rooted wetland plants is distributed in a 5-15cm plantation layer, the root system of the medium-rooted wetland plants is distributed in a 10-14cm plantation layer, and the root system of the deep-rooted wetland plants is distributed in a 20-60cm plantation layer. The plant configuration method allows the beneficial influences of the wetland plants on the wetland microbes to be maximally performed through reasonable layout of the kinds of the wetland plants on the basis of a wetland decontamination mechanism, effectively increases the quantity and the activity of the wetland microbes, and improves the wetland water treatment effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a plant configuration method for increasing the number and activity of wetland microorganisms. By scientifically and rationally configuring wetland plants with roots at different depths in the wetland, the number and activity of wetland microorganisms can be increased, and the artificial The effectiveness of wetlands. Background technique [0002] Constructed wetland technology is a sewage ecological treatment technology gradually developed in the 1970s. It simulates the ecosystem built by natural wetlands through engineering measures. Constructed wetlands mainly consist of wetland substrates, wetland plants and microorganisms. It uses the physical, chemical and biological synergies of wetland substrates, wetland plants and microorganisms to achieve efficient purification of sewage. At present, the outstanding effect of constructed wetland in sewage treatment is reflect...
