Abstract

The invention discloses a sewage treatment system of a horizontal baffling compound type artificial wetland, which is characterized by comprising multi-stage surface flow type artificial wetland chambers and multi-stage underflow type artificial wetland chambers connected in series in sequence, and separating walls and different water passing structures are arranged among the chambers. Various types of artificial wetland chambers connected in series are arranged in manner of horizontal baffling, and the bottom surfaces of the wetland chambers keep about 1 percent of longitudinal slopes. The invention can flexibly carry out multi-stage combination on different types of wetlands according to the characteristics and the treatment requirements of sewage, has long treatment flow and wide adaptability, and is not easy to block. The sewage flows through each treatment chamber of the horizontal baffling compound type artificial wetland in sequence in an automatic flow mode and is discharged after automatically completing all treatment processes.

Description

Technical field [0001] The invention relates to the field of sewage treatment, in particular to a secondary anaerobic horizontal baffle composite constructed wetland sewage treatment system and a sewage treatment method thereof. Background technique [0002] At present, the centralized treatment technology of municipal sewage in my country is relatively mature, and the sewage treatment efficiency is increasing year by year. However, in the vast rural areas and urban-rural junctions, except for some urban communities in water source protection areas that have simple sewage treatment devices, most of them are in a state of letting go, and are directly discharged into nearby rivers without any treatment. The nearby water bodies caused serious pollution. [0003] The above-mentioned decentralized sewage has the following characteristics: 1) Large daily variation coefficient of sewage water volume: Due to the small source area of ​​decentralized sewage and similar drainage rules, the d...
