Embodiment Construction

[0018] In order to make it easier for those skilled in the art to understand, we will explain the present invention in more detail below in conjunction with the drawings and specific embodiments.

[0019] refer to figure 1 , figure 2 Domestic sewage in rural villages and towns includes the domestic sewage collected by the drainage pipe network that has been cleaned and diverted, and the surface runoff sewage that has not been cleaned and diverted. The sewage treated by the pre-treatment facility 1 flows or is pumped into two vertical-flow constructed wetland plant beds, the sewage flows downward in the vertical-flow constructed wetland plant bed 2, and then advectively enters the vertical-flow constructed wetland plant bed 3, The sewage flows upward in the plant bed 3 of the constructed wetland, and concentrates on the upper part of the plant bed 3 and flows into the trough type artesian aerator 4 by itself. During the flow of the vertical flow artificial wetland plant bed,...

Abstract

The invention relates to a compound artificial wetland treatment process of domestic sewage in villages and towns in rural areas. The process utilizes an artificial wetland treatment technology to be matched with a trough type automatically-flowing aeration channel for treating domestic sewage in rural areas. The treated sewage according with the standard can be drained in a local water environment and recycled as agricultural irrigation or environmental water. Compared with the conventional sewage in rural areas, the process adopts a benign artificial wetland ecological system with a certainecological landscape value; if not used, the artificial wetland can be used for secondary tillage to plant crops or fruit tress, thereby obtaining better ecological environment benefit. The technology has greater popularization and application values in rural areas.

Description

technical field [0001] The invention relates to the field of domestic sewage treatment, in particular to a compound artificial wetland treatment process for rural and township domestic sewage. Background technique [0002] Rural domestic sewage includes sewage from Linpan homes and township sewage. Linpan homes are scattered, and the sewage is difficult to build a sewage pipe network for centralized discharge, and many households or several households that live in a concentration are treated separately; townships are villages, towns, towns, etc. that live in a concentration. , the domestic sewage is relatively concentrated, and the pollution to the local water environment is obvious. It is necessary to build a township sewage treatment plant or station for centralized treatment. There is a great need for sewage treatment technologies with low operating costs, high environmental and ecological benefits, convenient management, and low investment. At present, traditional secon...
