Problems solved by technology

During the use of this process, it was found that due to the relatively good quality of raw water in drinking water sources, the biofilm formation cycle on the surface of the biofiller in the pretreatment unit is long, the activity of the biofilm is not high, and the effect on water purification has not been effectively exerted.

Abstract

The invention belongs to the technical field of environment ecology engineering, and particularly relates to a wetland treatment type water treatment system beneficial to biological stuffing surface biofilm generation. The invention provides the wetland treatment type water treatment system, comprising a biological stuffing unit and a wetland unit, wherein the biological stuffing unit is used for performing biofilm treatment on a water body to be treated, and biological stuffing is arranged in the biological stuffing unit; the wetland unit is used for performing wetland purification treatment on the water body subjected to biofilm treatment, and the wetland unit sequentially comprises an emergent aquatic plant area and a submerged plant area according to a flowing direction of the water body; the biological stuffing unit and the wetland unit are in fluid communication with each other by a biological stuffing unit water outlet pipeline, and the biological stuffing unit and the wetland unit are also in fluid communication with each other by a backflow pipeline. The wetland treatment type water treatment system has the characteristics of short forming time, good active effect of a biofilm and high water purification efficiency, and the effect of treating the water body by the biofilm when the biological stuffing is applied to treatment on natural water bodies such as wetland and a river channel can be improved.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and specifically relates to a wetland treatment type water treatment method and system which are beneficial to the formation of biofilm on the surface of biological fillers, and further relates to a new method for forming biofilms on the surface of biological fillers. Background technique [0002] At present, in the field of raw water purification of contaminated drinking water sources, ecological purification technologies that are widely used mainly include artificial wetlands, ecological grass artificial media, and ecological floating beds. The process improves the raw water quality of drinking water sources. The Chinese invention patent specification with application number 201210181368.3 discloses a process, which includes a pretreatment purification unit, a composite wetland purification unit, a high-efficiency oxidation purification unit, a submerged plant purifica...
